The number of pupils hurting themselves is said to be at a high.
NHS figures obtained by BBC Newsbeat show a 20% rise in the number of 10 to 19-years-olds admitted to hospital because of self-harm injuries across England, Wales and Northern Ireland.
The government says it has asked experts to examine how to tackle self-harming and related issues in schools.
The NHS figures show the number of hospital admissions rose from 22,978 in 2012-13 to 28,730 in the following year.
Figures for Scotland were not available.
According to the National Association of Head Teachers and the Association of Teachers and Lecturers, spending cuts to local services have left schools without as much expert medical help as in the past.
