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.

Every school's change

64 schools with figures for both years

Schools still filling their classes in 2015/16, and schools opened since, are listed separately.

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.

Newer schools

1 school still filling its classes in 2015/16 or opened since, with 45 pupils. It isn’t in the figures above.
