One inadequate school in Wigan: new analysis shows the difference of education standards between rich and poor areas

The Liberal Democrats said the Conservatives "have let our children down" after decimating funding to schools across England.

RADAR analysis of Ofsted figures shows a significant disparity between the number of inadequate and outstanding schools in the poorest and richest areas.

In the North West, 76 schools were rated inadequate as of December 31 – including one in Wigan.

Of these, 36 were based in the 20 per cent most deprived places, while just six were in the wealthiest 20 per cent of areas.

Meanwhile, some 22 per cent of the schools in the wealthiest neighbourhoods were rated outstanding, compared to just 13 per cent of those in the most deprived places.

There was a reverse trend for inadequate schools, with one per cent of the schools in the wealthiest rated as inadequate, compared to three per cent of those in the poorest.

It means an inadequate school in the North West is three times as likely to be in an area with the highest deprivation levels than in the lowest.

Munira Wilson MP, Liberal Democrat education spokesperson, said: "Every child deserves a great education, no matter what their background is.

"Parents should not have to send their children to schools which have had their funding decimated by a Conservative Government that has lost interest in providing high-quality education."

Ms Wilson said school trips are being axed, teaching assistants laid off and classroom repairs ignored due to a lack of funding.

She added: "Far from preparing the next generation for the future, ministers have totally abandoned them."

Across England, nearly a third of 405 qualifying inadequate schools are based in areas where pupils live in the 20 per cent most deprived areas across the country, compared to just 19% of outstanding schools.

Of the 4,000 schools in the wealthiest areas, just one per cent are rated inadequate. This almost triples to 2.9 per cent for the poorest areas.

It means three times as many inadequate schools are in the most deprived 20 per cent of areas as in the richest.

A Department for Education spokesperson said: "Standards continue to rise with 90 per cent of schools now judged to be good or outstanding last year, up from 68 per cent in 2010. In the last year alone, 214,000 more children now attend good or outstanding schools.

"School funding is rising to £60.7 billion next year, the highest ever level in real terms per pupil.

This includes pupil premium funding, which will rise to over £2.9 billion in 2024-25 in line with inflation.

"We have significantly increased support for disadvantaged pupils through the £1 billion National Tutoring Programme and by expanding our support so more than double the number of children receive free school meals than in 2010."
