The number of pupils being permanently excluded in some areas has dramatically increased over the last year, figures obtained by Tesreveal.
In one local authority, permanent exclusions rose by more than 300 per cent between 2015-16 and 2016-17.
Three areas saw their permanent exclusions triple during the course of a year. Numbers at least doubled in 12 authorities and a total of 25 local authorities saw permanent exclusions increase by at least 50 per cent.
Behaviour and exclusion experts attribute these rises to increased pressures on schools, both academic and financial.
“For exclusions to be skyrocketing like that, it has to be biting somewhere,” behaviour expert Jarlath O’Brien said.
