Heading:  Learning Estate Strategy – Roll Projections
__________________________________________________________________
1. Summary
1.1 In order to support our comprehensive Learning Estate Strategy, which was
approved by this Board in August, Renfrewshire Council has worked with data
specialists Edge Analytics, to produce a full-estate pupil projection model that
spans the next 10 years. This model offers an estimate of the number of
pupils expected to attend each of Renfrewshire’s primary and secondary
mainstream schools, taking into account a number of key factors which will be
outlined in this report. The full overview of estate projection for the next 10
years can be found in Appendix 1. 
1.2  The findings from these projections are outlined, along with an analysis of the
implications and next steps for the schools where future capacity planning
interventions will require to be considered. 
1.3 This report also provides an explanation of the approach and key components
that support the construction of the roll-projection model, as well as supporting
detail to outline bespoke adjustments that have been made by Edge Analytics
to align the model to a Council wide school estate approach. 
__________________________________________________________________
2. Recommendations
2.1 The Board is asked to:
2.1.1. Note the contents of this report, including the final 10 year roll-
projection estimates for each of Renfrewshire’s primary and secondary
mainstream schools.

Page 2

Page 2 of 17 
2.1.2. Note the approach being taken to assess all schools identified in this
report as requiring future capacity planning to be undertaken, and the planned
next steps for each. 
2.1.3. Note that the recently approved Learning Estate Strategy approach will
be used to provide a strategic framework to progress planning for any long
term and permanent intervention considerations for the estate. 
2.1.4. Note the information provided on the approach and key components
used to create the roll-projection model, including the detail about the specific
model created for Renfrewshire’s mainstream school estate by the Council’s
commissioned partner, Edge Analytics. 
3. Background
3.1. Renfrewshire Council have engaged Edge Analytics to produce a roll-
projection model for the entire learning estate. Progressive prioritised phases
of work have been ongoing since early 2023 which has consisted of the
following outputs:
• A roll-projection model was produced in early 2023 showing a 10-year
projection for the following schools:
o Park Mains High School 
o Trinity High School 
o Dargavel Primary School 
o Bishopton Primary School 
o St John Bosco Primary School 
• Further subsequent modelling was produced in late 2023 for this cohort
of schools, extending the projection timeline to 15 years to support long
term estate planning and decisions making to manage the longer term
impact of the full build out of Dargavel village.
• A roll projection model for 10 years for the entire learning estate has
now been produced and is presented to this board to support overall
strategic learning estate planning. 
3.2. A series of reports have been presented to the Education and Children’s
Services Policy Board across 2023 and 2024 to outline the implications of this
work.
3.3. In Appendix 1 of this report, a table outlining the 10-year projections for all
schools in Renfrewshire is provided for reference. It should be noted this does
not include the Council’s two additional support needs schools, Riverbrae and
Mary Russell, as admissions to these establishments are allocated on a
needs basis, which cannot be projected through a roll-projection model for
catchment demand.

4. Roll Projections Summary 
4.1. Analysis of the trends forecasted for all schools in the estate can be seen in
Appendix 2 of this report, covering the next 10 years. This analysis  highlights
that  within the primary school estate by 2033/34:
• 8 schools are projected to grow by more than 10%.
• 22 schools are projected to decline by more than 10%. 
• 20 are projected to remain broadly static. 
4.2. Within the secondary school estate by 2033/34:
• 7 schools are projected to increase in capacity, 4 of which will be
greater than 10%.
• 4 schools are projected to decline.
4.3. National data shows birth rates are declining, and this impact emerges sooner
within the primary school estate and is reflected in a falling projected school
roll in almost half our schools within the next 10 years. It is expected the
emerging fall in rolls within the primary sector will subsequently and
increasingly feed through into the secondary estate, however the full impact of
this will be beyond the 10-year projection timeframe currently modelled. This
expectation of a subsequent impact within the secondary sector is consistent
with the limited scope 15-year projection modelling completed earlier in the
year to support primary and secondary estate planning emerging from
Dargavel village. 
5. Capacity Planning
5.1. As highlighted in Appendix 1, a projection is shown for all primary and
secondary establishments. This shows the expected level of catchment
demand for each school based on a series of datasets and calculations. For
background reference, an overview of how the roll projections are developed
is provided in Section 9 of this report. 
5.2. A placing request is a request for a place at a school of which the person
does not live within the catchment. An in-catchment request is a request for a
place at a secondary school where the person lives within the school
catchment but did not go to an associated feeder primary school. These
requests can only be considered once catchment demand has been met.
5.3. Whilst this report is not intended to focus on the detail of capacity planning at
individual school level, a brief overview of this process is provided below. For
estate planning purposes, roll projections are assessed against what is known
as the ‘planning capacity’ of each school. However, it should be noted the
planning capacity is a figure of how many children could be accommodated
from a space perspective within the school (based on national space metric
standards), and will rarely match the actual number of children in a school, as
classes require to follow policy and national directive on maximum allocations
which are as follows:
Stage  Class Maximum

P1 25
P2 30
P3 30
P4 33
P5 33
P6 33
P7 33
Composite Class 25 
S1 – S6 Practical class 20
S1 – S2 Classroom Activity 33
S3 – S6 Classroom Activity  30 
5.4. A definition of the two types of capacity measurements that are used are
provided below:
5.5. Planning Capacity – Planning Capacity is a physical, theoretical measure of
the total number of pupils which could be accommodated in a school, based
on the total number of teaching spaces, the size of those spaces and the
class size maxima (The Scottish Government 2014).
5.6. Working Capacity - Working Capacity is a dynamic and more realistic
measure of the total number of pupils which can be accommodated in a
school in a particular school session. The Planning Capacity is adjusted
based on the organisational needs of the school that session e.g. taking into
account pupil roll, composite classes, staffing etc. to calculate Working
Capacity (The Scottish Government 2014).
5.7. Local authorities are expected to be flexible and adapt accommodation to
meet the required working capacity of any given academic year.
Consequently, the purpose of the planning capacity is to support longer-term
planning to assess the required scale of the learning estate and any planned
future interventions that may be required.
5.8. It is important to emphasise the recently approved Learning Estate Strategy
will provide the strategic framework to support, at a full-estate level, the
review of any medium to long term capacity planning requirements and
considerations that emerge from the detailed analysis and interpretation of the
key outputs from the projection modelling. These could include for example,
consideration of catchment reviews; extension to buildings (either permanent
or temporary); or indeed new learning estate buildings.

5.9. Whilst the Learning Estate Strategy will support consideration of the estate
from a wider strategic perspective, the most appropriate response to short-
term capacity planning is at local level, as fluctuations in catchment demand
are a routine factor in regular education planning. Each year, Children’s
Services management, in collaboration with Head Teachers, undertake
capacity and class planning. This is addressed through the Council’s
admissions policy for aspects such as placing requests and associated
primary transition to secondary education. However, it is also managed at a
detailed level through timetable planning at secondary level, and class
planning at primary. This process can involve using additional flexible space
in schools that may not be ordinarily designated as classrooms in the capacity
figure of the school, such as General Purpose (GP) spaces, IT suites, flexible
learning rooms etc. In this process, the Council must duly consider its duty to
provide education to children in their catchment where possible and should
mitigate any impact on the effective delivery of the curriculum when
considering using additional space. It is of course important to note the use of
additional flexible school space is a short-term measure and would never be
intended to address long-term capacity requirements. 
5.10. When it is not possible to mitigate the catchment demand through additional
available accommodation within existing school establishments, the Council
would appropriately consider temporary accommodation to manage  any
short-to-medium-term capacity demand.
6. Findings from Projections – Primary Schools 
6.1. Upon review of the projections for the primary school estate, it is expected the
majority of the learning estate will be in a position to accommodate demand
over the next ten years. Whilst projections indicate that some establishments
are anticipated to come close to or even slightly over capacity, the
arrangement to accommodate this will be considered using the process
outlined in paragraph 5.8 and 5.9. 
6.2. However, there are a small number of schools that projections indicate require
priority capacity planning to be progressed, considered and future
interventions implemented. An overview of these establishments is provided
below. 
Dargavel & Bishopton Primary Schools - Long Term 
6.3. Capacity pressures through new housing development in Dargavel Village
have been regularly reported to this board and continue to be monitored
carefully. 
6.4. In the previous projections, last reported to this board in January 2024, a
range of scenarios were presented. These showed that the upper demand
scenario for primary-school places within Dargavel could reach a potential
maximum of 1,500 in 2033/34. The 15-year projections shared at that time
indicated 2033/34 would be the peak year in all scenarios, and demand would
start to fall year-on-year after that point. The updated 10-year projections
indicate that there could be 1,429 primary-school-aged children living in
Dargavel by 2033/34. This suggests long-term demand will be within the
range of previously published scenarios (albeit towards the upper end). As
previously reported to Board, projection modelling of new large community
growth areas similar to Dargavel Village, is complex and subject to a range of

Page 6

Page 6 of 17 
uncertain influences, including the pace at which the remaining development
is constructed, future birth rates and migration patterns and over the medium
term, and parental choice to retain or take up available places at the
neighbouring Bishopton Primary that is currently being used to temporarily
support Dargavel Village. In this context it is important that the projected roll
modelling is monitored against live data emerging from actual pupil
registrations each year. This will provide ongoing intelligence as to the degree
to which emerging demand is tracking, against existing projections each year.
This annual monitoring regime will inform and support any requirement for
early consideration of any further capacity interventions within Dargavel
village to provide additional temporarily and or permanent increase in
capacity.
6.5. In the current school year, 2024/25, the pupil projection model provided as
part of this report estimated that 219 pupils could be expected to begin P1
across both Dargavel and Bishopton Primary Schools. Provisional school
census information shows that only 165 P1s began school at Dargavel and
Bishopton this year. This means that actual pupil figures are currently trailing
the projected peak of 1,429 in year 2033/34 by 54 pupils (219 minus 165). As
outlined above, this will continue to be reviewed annually to understand if
lower actual demand develops as a continuing trend. 
6.6. Given the current projection model suggests that just over 1,400 children
should be expected in 2033/34, it is prudent to plan for accommodating this
level of demand but importantly recognising that this represents only a
temporary peak and should not in isolation drive decisions regarding long
term permanent capacity planning. Although no similar guidance exists in
Scotland, Education capacity planning guidance in England sets out clearly
that based on historic evidence for large scale housing developments, similar
to Dargavel, a peak period of education demand will emerge and local
authorities should plan for meeting both long term demand levels, through
permanent capacity provision and temporary peak demand period through
use of flexible capacity for example effective use of shorter life modular
accommodation – failing to approach capacity planning in this manner is likely
to result on over-provision of long term capacity.  
6.7. Previous 15-year modelling for Dargavel completed earlier this year,
concurred with the evidence led guidance from England, and indicated that
beyond the peak year of 2033/34, demand will begin to fall. Assuming a
similarly shaped demand curve, this suggests longer-term demand will fall to
around 1,260 pupils by 2038/39. The updated modelling indicates that in
2028/29 demand will equally be 1,260 which provides greater planning
certainty that temporary demand is likely to emerge over a 9-year window
between 2029/30 – 2038/39, with the maximum peak of circa 1,400 occurring
in 2033/34.  
6.8. The new primary school currently being developed in Dargavel will have a
planning capacity of 800, whilst the existing Dargavel Primary School main
building has proven to be able to operate at a level of 500, albeit there is
currently an additional capacity of 198 in place through temporary modular
classrooms. This provides total permanent long term planning capacity of
1,300 (800 + 500), sufficient to meet long term demand projections.
Additionally, should the temporary modular classrooms currently in place be
retained, this would provide total available capacity of circa 1,500, providing

Page 7

Page 7 of 17 
sufficient flexibility in capacity to meet the projected 9-year temporary peak
period in demand. 
6.9. In broad terms, this latest set of long-term projections for Dargavel remain
within previous planning scenarios and existing plans for permanent and
flexible temporary capacity remains appropriate. However, it continues to be
recognised that projection modelling of this nature is not exact and there
remains the risk that actual demand levels and patterns that emerge may
shift, both upwards or downwards. Actual demand will therefore continue to
be closely monitored and tracked against projections and as previously
reported to Board, this will provide the opportunity to consider early, the
implications of demand levels trending beyond the upper scenarios. In such
circumstances, several options exist for the longer-term capacity planning, all
of which have been referenced in previous reports to this board. The following
options were presented to the Education and Children’s Services Policy Board
on 18th January 2024:
• As outlined above, retention of the additional temporary modular
classroom capacity at Dargavel Primary School. As temporary
classrooms currently exist on site and the council already owns these,
they could remain in place for a longer period, securing flexibility in
capacity of up to 1,500. 
• Additional permanent capacity in the form of an extension at the
current Dargavel Primary School with a 268-capacity extension having
already been designed to provide confirmation that such an option was
viable and deliverable on the existing extended site.
• Utilise surplus capacity at Bishopton Primary School, which is expected
to become available after 2027 when the new Dargavel Primary School
opens. This would require catchment areas to be redrawn.
• It was further noted in the report that additional flexible space in the
new Dargavel primary school could be utilised, albeit this option would
not be preferred. This new primary school has flexibility as a core
design principle meaning that it can accommodate over and above its
theoretical planning capacity.
6.10. A combination of any of the above options would also be possible. The
ongoing monitoring arrangements and future long term projection updates will
ensure if additional intervention is required the opportunity to engage with the
school and wider communities to determine the most appropriate approach
will be possible several years in advance.
Dargavel & Bishopton Primary Schools - Short Term 
6.11. Following construction completion of the new two class permanent block at
Bishopton Primary School, the theoretical planning capacity for this school is
530. Dargavel Primary school has capacity for circa 700 children due to
additional capacity existing with the temporary classrooms at the school.
6.12. For the short term i.e. August 2025 and August 2026, live data has been used
to analyse the expected demand at both Dargavel Primary School and
Bishopton Primary School over this short-term period. This is primarily due to
the roll projection model, which is primarily focused on long term demand not

Page 8

Page 8 of 17 
adjusting for the immediate short term impact of the Dargavel catchment
children who will instead attend Bishopton Primary School through the ballot
process, 
6.13. This analysis is captured in the table below which shows the roll projection
model, applies the previously agreed cap of 75 P1s to Dargavel, and
reallocates the numbers above that to Bishopton. As noted, only 165 P1s
started across Dargavel Primary and Bishopton Primary this year. This is a
reduction from the projected 219 that was factored into the pupil projection
model, contributing to the expected school roll each year as seen in Appendix
1. These live figures, along with the cap of 75 P1s at Dargavel Primary School
are shown below: 
6.14. This shows that there is a potential need for capacity planning to be
undertaken at Bishopton Primary School in 2026 to meet demand before the
new Dargavel Primary School opens in 2027. However, as noted, this
reduction in P1 entrants compared to estimated projections, could have a
positive impact on school capacity planning for the longer term, should figures
continue to trend below estimated levels. 
6.15. As can be seen from the above, with the impact of reallocating additional
pupils above the 75 cap from Dargavel to Bishopton, the estimated roll of
Bishopton for August 2026 is 583, above the planning capacity of 530. In
response, the following options are currently being kept under review:
• Capacity planning national guidance could be utilised to implement
what is known as ‘team teaching’, which is the process of having more
than one teacher in a classroom to accommodate more children than
the prescribed maximums (25, 30, and 33) only if space allows to
retain 1.7m2 per pupil as per approved guidelines. As Bishopton
Primary has large traditional classrooms, it is already known that
significant additional space exists in classrooms to allow this measure
to be implemented, if required.
• Implement additional temporary classrooms at either Bishopton
Primary School, or on the vacant land in the Council’s ownership,
directly joined on to Dargavel Primary School. 
6.16. If demand does not keep up with Edge projections and live data continues to
show a lower number of pupils entering at P1, no intervention may be
required. 
6.17. All options require to be carefully considered, and it is proposed that
engagement is undertaken with the school communities of both Dargavel and
Bishopton Primary Schools, in collaboration with Head Teachers, to help

determine the appropriate course of action. The priority, as always when
capacity planning in the school estate, is to protect the education experience
and curriculum delivery. 
St John Ogilvie Primary School
6.18. An increase in demand for St John Ogilvie Primary School in Paisley can be
seen in the projections for this school. An overview of projections is provided
below: 
6.19. As projections show the school roll at St John Ogilvie could increase above
the planning capacity figure in the next academic year, immediate planning is
being undertaken to assess current school operation and schedule of
accommodation to determine if any additional teaching space can be created
in the school, to accommodate this demand in the short-term. 
6.20. It is also prudent to assess the level of placing requests submitted to this
school to determine if they are having an ongoing impact on the ability to
accommodate future catchment demand. Should this be the case, as with
other schools in a similar position, placing requests can be reviewed in line
with the council’s admissions policy to ensure catchment space is prioritised.
An initial review of placing requests shows in the last 7 years (full primary
cycle) there have been 110 placing requests granted to St John Ogilvie. This
is a significant number of placing requests for a school of this size and can be
managed as part of this review. 
If there are still concerns about the ability to meet the catchment demand after
the above has been considered, then alternative options will be assessed as
part of the wider Learning Estate strategy. 
7. Findings from Projections – Secondary Schools 
7.1. The secondary school estate projections provided in Appendix 1 shows there
are four schools where capacity will require to be managed over the next ten
years. An overview of these establishments is provided below: 
Gryffe High School 
7.2. Demand for Gryffe High School has been high for several years. This is
managed on an ongoing basis by the Council’s admissions policy, to ensure
the overall school capacity is maintained. 
7.3. Projections show demand for Gryffe could slightly exceed the formal planning
capacity of the school in the next few years, although this is then forecast to
fall back well below capacity. The Council’s admissions policy shall be
implemented in these instances to manage any minor expected peak over
and above the school capacity. This can involve limiting placing requests
where catchment demand is required, whilst an assessment will also be

undertaken to interrogate timetable demand and any additional flexible use of
space that could be utilised to meet any short-term demand. 
Beyond any short-term capacity planning, the recently-approved learning
estate strategy will guide any permanent intervention in future years. 
An overview of projections for Gryffe is provided below: 
Park Mains High School
7.4. Work is under way to extend Park Mains High School to accommodate up to
2,000 pupils. Projections show the school roll is expected to steadily increase
over the next ten years. An overview of projections for Park Mains is provided
below: 
7.5. Park Mains currently has a modern temporary classroom block in operation
from this academic year providing 5 classrooms, increasing the capacity of
the school to 1,756, from the previous formal planning capacity of 1,591. This
ensures any short-term demand can be accommodated. The demand over
the next three years (until the school is extended) will be monitored, as it is
possible that live data will be less than the forecast. For context, in this current
academic year, the school is trailing the estimated projections by 13, and
should that trend continue, the number of pupils attending the school would
be less than projected, reducing the impact. 
7.6. The projections for Park Mains show the school roll exceeding 2,000 in years
2032/33, and 2033/34. As previously reported to Board, the number of placing
request and in-catchment requests to Park Mains are included in the
projection model and are a contributing factor in the school roll temporarily
exceeding capacity in the future. Therefore, further mitigation can be provided
by managing and reducing the number of placing requests to the school
through the admissions policy. 
7.7. To provide an understanding of how much this could expect to reduce the
overall school roll, the following levels currently exist across Park Mains,
covering a 6-year period:

Total combined 205 
7.8. The table above shows the overall school roll of Park Mains can be reduced
by applying the Council’s admissions policy and implementing a phased
reduction of requests. It is important to note any pupil currently in the school
has a right to remain, and the admissions policy only applies to the point of
entry at a school. 
7.9. This latest set of data and analysis shows Park Mains is expected to
accommodate long-term demand. Previously officers reported to Board that
demand for Park Mains High School was expected to drop after a decade
(within the 15-year projection model). This reflects the impact of school roll
decline in other communities within the catchment and reinforces that pupil
numbers from Dargavel Village in isolation do not determine the projected roll.
Whilst the growth of the Dargavel development will have a significant impact
on the school roll of Park Mains, analysis shows the roll for every other
feeder primary school for Park Mains is set to decline, with the exception
of Langbank which may experience very limited  growth. Only when this is
combined with the algorithm used in the roll projections model to determine
housing growth and migration movement in and out of the catchment, can the
estimated school roll be assessed. 
7.10. As was noted in response to the statutory consultation for a new primary
school in Dargavel, the need to consider secondary provision for this area
was a priority raised by the community. It is important to emphasise similar to
primary provision, continual  close monitoring of both actual demand and
future  projection updates for Park Mains will be undertaken , and should
there be any indication the capacity will come under pressure, the wider
learning estate will be considered to develop options for the most appropriate
solution to secondary provision in this area of Renfrewshire.
7.11. St Andrew’s Academy
7.12. Whilst St Andrew’s Academy was built with a planning capacity of 1,250, it
has operated efficiently above this level for several years. This has been
achieved by effectively managing timetable demand, implementing flexible
use of classroom space, and applying the Council’s admissions policy. 
7.13. Projections show the demand for St Andrew’s is expected to broadly remain
consistent for the next 5 to 6 years. A small increase can be expected as
housing development across the Paisley area continues, however the wider
aspect of migration in and out of the area as well as full analysis of all feeder
primaries show some catchment populations declining whilst others increase,
giving a balanced net effect on the school roll. An overview of projections for
St Andrew’s Academy is provided below:

Page 12

Page 12 of 17 
7.14. The council’s admissions policy can also be applied to mitigate any impact on
the ability for St Andrew’s Academy to operate efficiently. Whilst placing
requests are managed at levels that can be accommodated currently, the
school currently has a significant level of in-catchment request. 
7.15. A table has been provided for St Andrew’s below, showing current levels of
requests in this school:

7.16. This analysis shows there is an ability through the council’s admissions policy
to reduce the school roll of St Andrew’s Academy, should any capacity
pressure be applied through demand. Analysis also shows that non-
denominational secondary schools in Paisley have sufficient capacity to
accommodate any impact of realigning pupils to catchment schools through
the admissions policy.
Trinity High School 
7.17. Trinity High School projections also show planning is required to mitigate the
projected school roll within the next two years and beyond. An overview of
projections for Trinity High School is provided below: 
7.18. As is established practice and process across the school estate, a thorough
assessment of available space in the school will be undertaken to determine
where timetable flexibility can be used to manage short-term capacity.
7.19. It is noted by officers that the mitigations outlined at 7.7 to help manage and
reduce pupil roll at Park Mains High School is likely to increase demand for
Trinity High School further. This will be managed as part of the medium-term
Learning Estate Strategy and detailed planning on this continues. In addition,
as highlighted previously in the report, placing requests and in-catchment
requests can be managed through the admissions policy and this will also be

7.20. The above shows there is an ability to reduce capacity pressure on this school
by applying the admissions policy. 
St Benedict’s High School 
7.21. Figures in Appendix 1 show that St Benedict’s could come close to, or slightly
exceed its planning capacity for a short period of time. An overview of
projections for St Benedict’s is provided below: 
7.22. These figures will be monitored to determine if the estimates are produced as
projected where short term local measures can be taken through for example
additional use of space or utilising the Council’s admissions policy to manage
numbers. 
8. Estate Summary 
8.1. The analysis provided above confirms options exist for mitigating increasing
school capacities at both full-estate level and local school level, and a
fluctuating school roll should be seen as a normal process with measures that
can be applied on a year-to-year basis. 
8.2. There is a recurring theme in secondary school provision where a significant
number of in-catchment, and placing requests exist within the school estate.
Parents and carers have a right to request what school their child attends, and
it is for the Council’s admissions policy, which follows legislation, to apply
control to this. Should the council be required to manage requests, this would
have a positive impact on realigning pupils to their intended catchment
schools.
8.3. The agreed Learning Estate Strategy is pivotal to the development of the
school estate and to medium and long-term capacity planning across

Renfrewshire. The strategy will enable the council to consider all
Renfrewshire primary and secondary schools in a holistic manner, the
relationship and interaction between schools and the optimum estate design
to deliver the required interventions. 
9. Roll Projection Methodology 
9.1. The purpose of conducting a pupil-projection analysis is to determine an
approximation of the future expected number of pupils that require primary or
secondary education in Renfrewshire. A projection methodology is built on a
foundation of historical data for births, NHS data, primary and secondary
school census information, and housing land audit which outlines known
development in the area. 
9.2. Renfrewshire Council has partnered with Edge Analytics to produce a
bespoke model based on their tried-and-tested methodology. An overview of
how this model is created including the data sets used, and processes for
determining projections is outlined in Appendix 3 of this paper. 
9.3. An important aspect of roll projection models is they are merely an informed
estimate There are many significant variables, including the fundamental
aspect that the expected number of births in an exact geographical area can
only be estimated based on historical trends, and national datasets. Pupil
projections produced through these models are thus best used for high-level
future planning and estate management to determine any intervention that
may be required in years to come.
9.4. With the above information, it is therefore essential that pupil projections are
used as a mechanism to identify where mitigations should be considered in
advance of any potential capacity issues. Pupil projection should be assessed
against the school’s planning capacity. As noted in this report, a planning
capacity is a notional figure of an approximate number of pupils that can be
accommodated, but this figure can be flexible when it comes to determining
the true working capacity. 
Pupil Product Ratio – New House Building
9.5. The pupil product ratio (PPR) is a figure that is derived from assessing
historical trends that estimates the number of children typically generated by a
new housing development. These figures are used to determine the pupils
generated when a new house is built, and used to support proposed levels of
developer contributions that are sought through the planning application
process. Renfrewshire has used a PPR rate for a number of decades, and
this was revised in 2018 following a benchmarking exercise with other local
authorities. It is important to note that the PPR methodology is only used to
determine the pupils produced for new houses built in any particular
year. The PPR rate does not apply to existing housing that has been built in
any previous year, to the year in question. This therefore means that for a roll
projection model, the PPR rate is only one element that is considered. 
9.6. As noted, the PPR is also used to assist with the production of pupil forecasts.
When considering PPR for roll projections, the PPR is applied to any new
build house to determine the number of pupils that it expects to generate
when a family move into that home. These pupils are then applied to the
appropriate school and year group using historical data as part of the

Page 15

Page 15 of 17 
projection model. This PPR rate is only ever applied once – when the house is
built, it is ongoing migration factors that need to be considered to understand
the number of pupils moving into a home that already exists.  
9.7. From a Renfrewshire wide perspective, there is an average PPR rate of 0.27
for primary and 0.13 for secondary which equates to the number of pupils
generated per new house built. The impact of this is applied to relevant
catchment schools with a series of other conditions such as historical school
transitions, as well as migration rates in and out of the local area. It is critical
to note that when planning for future school capacities, the PPR rate is only
one factor used within the methodology to determine the impact on school
rolls. There are many factors that must be considered, which is why a roll
projection methodology is the only appropriate way to assess this. The
following considerations must be given when considering a PPR rate:
• The number of pupils expected to be generated do not all arrive at
once. (e.g. a housing development of 200 houses multiplied by the
PPR of 0.27 equates to 200 X 0.27 = 54 pupils). They are also
assigned across all the class stages at the school and not just at entry
level.
• The Housing Land Audit outlines an indicative programme of
housebuilding and presents a 7-year forecast. Using the scenario
above, the 54 pupils estimated as generated by a development must
then be assigned against the proposed programme of housebuilding,
and the years this equates to. Assumptions are applied to spread the
potential pupils generated across the pace of housebuilding for that
specific development.
• When allocating potential pupils generated (e.g. 54) to a school,
historic rates are used to allocate the appropriate percentage to non-
denominational, and denominational catchment schools. 
• The PPR is only one aspect of roll projections, and it must be
assessed in collaboration with migration factors for people
moving both in and out of a catchment area, as well as historic
school trends, current school census information, transitions
statistics and placing request data. This is where migration factors
play a crucial role in estimating school rolls, particularly in large new
build developments, as the impact of migration (families moving in or
out of homes that have already been built previously) is considered in
the roll projection model but cannot be determined by assessing a PPR
rate in isolation. 
Live Data Monitoring 
9.8. When assessing ongoing estimations for pupil projections, it is fundamental to
estate capacity management to be monitoring live data. As noted, roll
projections simply produce an estimate of the number of pupils expected to be
at each school in years to come, and will not result in the exact number of
pupils.

Page 16

Page 16 of 17 
9.9. Typically, roll projections would be updated each year. As an interim measure
to monitor what is expected to happen in the immediate future (e.g. the next
academic year), there is an opportunity to assess live data in the form of:
• P1 registrations for the upcoming academic year.
• P7 transfer to secondary schools.
• In-catchment and placing request applications to attend an alternative
school.
9.10. These figures build an accurate picture of how many pupils are going to be
attending a school and can be matched against the estimated pupil
projections. By comparing the live data (registrations and placing requests)
with projections, officers can quickly determine if actual demand is trailing or
exceeding what was projected. This in turn informs any mitigations applied at
a local level, through the usual capacity planning process or by applying the
admissions policy.
______________________________________________________________ 
Implications of this report 
1.  Financial 
Any mitigations that are required to accommodate pupils in the short term
at local level, or by administering the Council’s admissions policy will bring
no, or minimal financial impact. Any financial impact of opening a new
classroom to accommodate catchment pupils will require teaching resource
costs, and classroom provisions. This is a standard process that is
managed in line with department budgets. For any further measures that
require to be implemented, these will be progressed in line with the recently
approved Learning Estate Strategy and its associated financial model. 
2.  HR and Organisational Development 
None. 
3. Community/Council Planning 
Reshaping our place, our
economy and our future 
-  The learning estate shall be
appropriately scaled and equipped
to meet curriculum expectations and
deliver an appropriate learning and
teaching experience for all. 
4.  Legal 
None. 
5.  Property/Assets 
Roll projections will allow the learning estate to be scaled appropriately,
with consideration for any future capital investment required to meet the
demand needs. Similarly, roll projections will identify any establishments
that are showing as having significant surplus capacity that can be
considered by the wider Learning Estate Strategy.

6.  Information Technology 
None. 
7.  Equality and Human Rights   
The Recommendations contained within this report have been assessed in
relation to their impact on equalities and human rights. No negative impacts
on equality groups or potential for infringement of individuals’ human rights
have been identified arising from the recommendations contained in the
report. If required following implementation, the actual impact of the
recommendations and the mitigating actions will be reviewed and
monitored, and the results of the assessment will be published on the
Council’s website. 
8. Health and Safety
None. 
9. Procurement 
Any procurement work required to address future capacity needs will be
conducted in collaboration with the Council’s Procurement team and
adhere to appropriate regulations. 
10. Risk 
The production and monitoring of roll projections is a mechanism of risk
management to plan the future scale of the learning estate and any
subsequent mitigations that are required to be implemented. 
11. Privacy Impact
None. 
12.  Climate Risk
None. 
13.  Children’s Rights
This report does not cover a new policy, function, or strategy nor a
substantive change to an existing policy, function or strategy which will
have an impact on children’s rights. When considering any future school
provision, the impact this will have on children is a key consideration, and
any work will be based around the direct needs of children to allow their
education experience to thrive. Whilst children have a right to choose
where they wish to attend school in collaboration with their parents, the
council’s admissions policy applies to ensure that schools that are
oversubscribed can be managed.

edge-ucate Mainstream Stakeholder Note  1 
2023–24 Academic Year  
Introduction
1.1 Edge Analytics has produced pupil forecasts for schools in Renfrewshire using its edge-ucate
Mainstream pupil projection model. This note provides an overview of the edge-ucate Mainstream
model, a summary of its key data inputs and a description of the forecasting methodology.
Model Overview
1.2 edge-ucate Mainstream is a modelling framework for mainstream pupil forecasting, developed by
Edge Analytics to support local authorities in their school place planning activities.
1.3 Edge Analytics has calibrated its edge-ucate Mainstream model for Renfrewshire using the latest
available evidence on resident pre-school age children, local schools and their pupils1, together with
assumptions on the potential impacts of migration and planned local housing developments on future
pupil numbers.
1.4 The model has been configured with a 2023–24 base year, providing a 10-year forecast for both
primary and secondary year groups under three scenarios:
• The BASE scenario assumes that there will be no change in the size of pre-school,
primary or secondary cohorts over time.
• The HOUSING scenario includes the impacts of planned housing on cohort size,
through the application of primary and secondary pupil yield factors to a trajectory of
planned housing growth. 
• The MIGRATION+HOUSING scenario includes the impacts of migration and planned
housing, combining the housing and pupil yield assumptions of the HOUSING scenario
with assumptions on the impact of pre-school, primary and secondary migration on
cohort size.
Data Inputs
1.5 The edge-ucate Mainstream model for Renfrewshire includes the following key data inputs:
• Details of each mainstream school in Renfrewshire, including recent and planned
school changes. In total, there are 61 open schools in Renfrewshire: 50 primaries (16
denominational and 34 non-denominational) and 11 secondaries (3 denominational

• A list of primary and secondary non-denominational catchment areas in Renfrewshire.
These are the smallest geographical unit used by the edge-ucate Mainstream model. 
1 edge-ucate Mainstream is configured to provide forecasts for mainstream schools located in Renfrewshire. Pupils
attending independent/special schools, alternative provision or schools located outside Renfrewshire are not included.

• A 3-year history of September school census data, providing a count of pupils by
primary non-denominational catchment area, year group (P1–S6) and school attended
(consistent with the schools list) in 2021–22, 2022–23 and 2023–24.
• Pre-school population data for 2021-22, 2022-23, and 2023-24, providing a count of
resident children aged 0+ to 5+ (by single year of age) by primary non-denominational
catchment area, sourced from National Records of Scotland mid-year population
estimates and Health Visitor data.
• Estimated births for each primary non-denominational catchment area, derived using
historical Health Visitor data.
• A trajectory of planned housing development by primary non-denominational
catchment area, with an accompanying primary pupil yield factor2 of 0.27 and a
secondary pupil yield factor of 0.13.
Forecast Methodology
1.6 The edge-ucate Mainstream forecasting methodology for Renfrewshire comprises a series of stages,
which are summarised in Figure 1 and described below.

Stage 1: Pool of Resident Pre-School Children
1.7 In Stage 1, a pool of resident pre-school children aged 5+ (P1 age) is identified for each primary non-
denominational catchment area in Renfrewshire using the pre-school population data and estimated
births:
• In the BASE and HOUSING scenarios, all children remain resident in the same primary
non-denominational catchment area until age 5+.
• In the MIGRATION+HOUSING scenario, migration factors are applied to the resident
pre-school population in each primary non-denominational catchment area, adjusting
the size of each cohort in consecutive forecast years. The migration factors are based
on the trends in the 3-year history of pre-school population data.
Stage 2: Primary Intake
1.8 In Stage 2, an intake rate for each primary non-denominational catchment area identifies the
proportion of resident children aged 5+ (from Stage 1) that enters mainstream primary education (P1)
in Renfrewshire. Transition rates identify the proportion of these children that enter specific primary
schools, allocating pupils from each primary non-denominational catchment area to each primary
denominational school and primary non-denominational school, in line with existing catchment area-
to-school pupil flows. Inflow adjustments identify any additional P1 pupils that enter each primary
denominational school and primary non-denominational school from outside the council area. These
assumptions are based on trends in the 3-year history of pre-school population data and school
census data.
Stage 3: Primary Cohort Progression
1.9 In Stage 3, P1 pupils (identified in Stage 2) transfer to successive primary year groups (P2–P7),
accounting for migration and/or new housing:
• In the BASE scenario, all pupils remain in the same primary school until P7.
• In the HOUSING and MIGRATION+HOUSING scenarios, primary pupil yield factors
are applied to the number of planned homes in each primary non-denominational
catchment area. The resulting yield is allocated to mainstream primary schools
(denominational and non-denominational) in Renfrewshire in line with existing
catchment area-to-school pupil flows.
• In the MIGRATION+HOUSING scenario, migration factors are additionally applied to
the number of pupils in each primary school (denominational and non-denominational),
adjusting (up or down) the size of each cohort in consecutive forecast years, based on
trends in the school census data.
Stage 4: Secondary Intake
1.10 In Stage 4, an intake rate for each primary non-denominational catchment area identifies the
proportion of resident P7 pupils (from Stage 3) that enters mainstream secondary education (S1) in

Renfrewshire. Transition rates identify the proportion of these pupils that enter specific secondary
schools, allocating pupils from each primary non-denominational catchment area to each secondary
denominational school and secondary non-denominational school, in line with existing catchment
area-to-school pupil flows. Adjustments are made for pupils resident outside the council area. These
assumptions are based on trends in the 3-year history of school census data.
Stage 5: Secondary Cohort Progression
1.11 In Stage 5, S1 pupils (identified in Stage 4) transfer to successive secondary year groups (S2–S6)
accounting for migration and/or new housing. The Stage 3 methodology is used.
1.12 From S4 onwards, pupils are transferred to successive secondary year groups (S5 and S6) using stay-
on rates, which adjust the size of each cohort (at each secondary school) in consecutive forecast
years. The stay-on rates are based on secondary school-level trends in the 3-year history of school
census data.
