There is currently no limit on the size of most primary and secondary school classes in England although infant classes – for pupils aged four to seven – have a statutory maximum of 30 pupils.
Some exceptions are permitted, such as including a child with special educational needs who is partly educated in a special school as the 31st pupil.
According to official Department for Education data, 15 primary schools in Portsmouth have classes with more than 30 pupils.
In total the schools are home to 36 classes with more than 30 pupils, containing 1,186 children.
