Every school's change

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 or a new school nearby can also explain a big rise or fall.

Newer schools

11 schools still filling their classes in 2015/16 or opened since, with 1,636 pupils between them. They aren’t in the figures above.
