Falling pupil numbers should lead to smaller class sizes, says union

Falling pupil numbers in England’s schools should be used to cut class sizes, the largest education union has said.

Daniel Kebede, the general secretary of the National Education Union (NEU), told the BBC around a million pupils are being taught in classes of more than 31 children.

Between 2023 and 2029 primary pupil numbers are expected to fall by 6.8%, with secondary numbers stable, according to the Department for Education.

New government figures show a modest fall in the number of school teachers overall, and progress towards the government’s target of 6,500 extra teachers which covers secondary and special schools, as well as further education colleges.

The latest statistics show 4,654 teachers in those settings, which represents solid progress against their target of 6,500 by the end of the parliament.

Overall, there was a fall in 2025 of 1,900 full time teachers in schools.

The government clarified in April 2026 that its manifesto promise of extra teachers does not cover primary schools or early years.

With primary pupil numbers falling, the government has cut its target for recruiting new teachers for the next school year by 23%.

Kebede said instead of cutting its teacher recruitment, the government should use the “historic opportunity” of falling pupil numbers to make class sizes smaller.

“At the moment we have the largest class sizes in Europe, a million children taught in classes of 31 or more”, he said, adding that under the last Labour government teacher numbers fell more slowly than pupil numbers.

He said teachers were needed to deliver on government plans to support many more children with special educational needs in mainstream schools by 2030.
