RESEARCHERS laid into the “burning injustices” in the education system yesterday after finding that half of pupils expelled from school have recognised mental health problems.

The Institute for Public Policy Research (IPPR) found that on average 35 children are excluded from schools in England every day — the majority of them about to sit their GCSEs.

Researchers also found that black students are four times more likely to be excluded.

The think tank even suggested that the number of excluded kids with mental health problems may rise to 100 per cent once undiagnosed problems are taken into account.

IPPR spokesman Kiran Gill warned that discrimination in school exclusions was “a crime” and called on Prime Minister Theresa May to address the issue of “vulnerable children being thrown out of England’s schools.”

National Union of Teachers general secretary Kevin Courtney warned that the education system is “creating exam factories in which increasingly children feel demoralised while cuts to funding leave some schools without adequate support to cope with serious behavioural or mental health issues.”
