Schools at or over capacity
A school is identified as at or in excess of capacity when their pupil number on roll is greater than or equal to capacity. A schools’ reported capacity may not reflect the entirety of a school’s physical space, and therefore in some cases the number of pupils on roll can be higher than the capacity, without the school being overcrowded. Some schools choose to operate in excess of their stated capacity because they feel that they can comfortably do so. Schools sometimes use non-teaching accommodation - for example a library - for teaching space.
Overall, the number of state-funded schools that were at or in excess of capacity in 2023 is similar to 2022 at 3,670 (18% of schools). This is lower than the 4,370 (22%) schools in 2010 when the series began.
The number of state-funded primary schools that were at or in excess of capacity remained similar to 2022, at 2,880 schools (17%) in 2023. Of which, 520 are operating at but not in excess of capacity, 1,600 exceed by fewer than 10 pupils and 760 exceed by 10 or more pupils.
The number of state-funded secondary schools that were at or in excess of capacity remained similar to 2022, at 790 schools (23%) in 2023. Of which, 10 are operating at but not in excess of capacity, 130 exceed by fewer than 10 pupils, and 640 exceed by 10 or more pupils.
Pupils in places that exceed their school's capacity
Where the number on roll is higher than a school’s capacity, the number of pupils in places that exceed their school's capacity is the difference between number on roll and capacity.
The number of pupils in places that exceed their school's capacity was similar to 2022 at 59,000 (0.7% of places) in 2023. This is lower than the 97,000 pupils in places that exceeded their schools' capacity in 2010 (1.2% of places).
In primary schools, there were just under 22,000 pupils in places that exceed their school's capacity, a decrease since 2022. This is in line with a decrease in pupil numbers, as the proportion of places is similar to recent years at 0.4%.
In secondary schools, there were 37,000 pupils in places that exceeded their school’s capacity, an increase since 2022. This increase is in line with a rise in pupil numbers in 2023, as the proportion of places remains the same at 0.9%. This continues the upward trend in recent years, which corresponds to the school-age population that is now in secondary school phase.
Unfilled places
A school has unfilled places if its capacity is higher than the number of pupils on roll. The number of unfilled places is the difference between the capacity and the number on roll.
As of May 2023, 83% of primary schools (nearly 14,000) had one or more unfilled places. This rate has been the same since 2021 and maintains the highest rate in over a decade, reflective of the falling primary population.
For secondary schools, 77% had one or more unfilled place (nearly 3,000 schools). This rate has been the same since 2021. The proportion of secondary schools with unfilled places rose steadily from 72% in 2010 to 86% in 2016 as secondary schools added capacity in preparation for the larger secondary population. Since then, the proportion of places unfilled has fallen as secondary pupil numbers increased.
Unfilled places can be evidence of local authorities having planned ahead for future need, as the increase in pupil numbers at primary level is now moving into secondary level and will continue to do so over the coming years. Unfilled places can also be attributed to the building of whole new schools, which fill up from the bottom, leaving space in the upper years until those year groups work their way through. In some areas, low or declining need for places will also contribute to the number of unfilled places.
In 2023, there were 578,000 unfilled places in primary schools, an increase of 1% from 569,000 in 2022, and 26% more than in 2010 (458,000).
There were 465,000 unfilled places in secondary schools, a decrease of 7% from 502,000 in 2022, although 31% more than 2010 (355,000).
Overall, in primary and secondary schools, there were 1 million unfilled places (12% of total school places available), a decrease of 28,000 places since 2022, however the proportion of the total places available remains similar. This is an increase from 814,000 places in 2010 (10% of total school places available). The increase is a combination of the population having moved into and then out of primary over the last 12 years, and secondary capacity being added in preparation.
At local authority level there is variation in the percentage of unfilled school places. For primary schools this ranges from 3% (Wolverhampton) to 29% (Westminster and Lambeth). For secondary schools this ranges from between 3% (Kensington and Chelsea) to 24% (Barking and Dagenham).
