Growing and falling since 2015/16
Each school's change in pupils over 10 years, from 2015/16 to 2025/26. A change of 10% or more either way counts as growing or falling.
30 schools with figures for both years
Average class size in these schools went from 26.5 in 2015/16 to 23.6 in 2025/26. 11 of the 13 schools that fell by 10% or more kept or added classes. A fall in pupils can mean smaller classes rather than fewer children wanting places. Smaller classes

Ranked by percentage change. Only schools with 50 or more pupils in 2015/16 are ranked, leaving out any still filling their classes then, because a few pupils make a big percentage in a small or new school. An amalgamation, a new school nearby or smaller classes can also explain a big rise or fall.
