Pupil premium funding should be trebled to support disadvantaged pupils in the wake of the Covid crisis, a multi-academy trust leader has said.

Oasis Community Learning founder Steve Chalke warned that the learning gap between financially disadvantaged and better-off pupils in England “has become a gulf”.

He said recent research suggests disadvantaged children fell further behind during the lockdown than more affluent pupils, and called on the government to treble the pupil premium funding.

The boss of Oasis, which is responsible for 31,500 children at 52 academies across England, told the BBC: “Government should respond to the need before it causes irrevocable damage by trebling this funding, at least over the next three years, and focusing it on children living in persistent poverty and facing long-term disadvantage.

“It is vital that government makes this move now, to ensure that a generation of children, already disadvantaged before the Covid-19 lockdown but whose situations have deteriorated even further, are not completely abandoned, doomed to spend their lives struggling for opportunities their peers will have ready access to, rather than flourishing.”

Mr Chalke also called for a boost to the government’s £350 million National Tutoring Programme (NTP).

He told the broadcaster the funding for the scheme, which is aimed at helping disadvantaged pupils catch up after lockdown, “is far too little” and does not do enough to address the “aching long-term need to narrow the disadvantage gap”.

In a statement to the BBC, the Department for Education (DfE) said the classroom was the best place for disadvantaged pupils to be, where the government’s £1 billion Covid-19 catch-up package was “tackling the impact of lost teaching time”.

The statement said this includes £350 million for less affluent pupils through the NTP, “which is in addition to our £2.4 billion pupil premium to improve these pupils’ attainment and outcomes”.

A spokeswoman added: “Headteachers and school leaders are best placed to make decisions about their pupils and which of them need the most support.”
