Schools educating young people permanently excluded from mainstream education say they are under pressure due to a rise in exclusions.
Permanent exclusions in Surrey rose 81% from 59 in 2018-19 to 107 in 2021-22.
The head of three Pupil Referral Units (PRUs), which educates excluded and suspended pupils, said demand for its service had grown since the pandemic.
Amy Smith, director of education at the Inclusive Education Trust, said the need for its services was “the highest that I’ve ever seen”.
“There is not enough to support young people, particularly those exhibiting challenging behaviour,” she said.
