Apparently, the South West is the region most being harmed by this underfunding.
“The number of state secondary schools falling into deficit in England has almost trebled in the last four years to more than a quarter, research says.
Analysis by independent think tank the Educational Policy Institute (EPI) found the proportion of local authority secondaries in deficit rose from 8.8% in 2013-14 to 26.1% in 2016-2017.
Its study of official figures also found a significant increase in the number primary schools in deficit.
The government disputed the findings.
The EPI report focuses on local authority schools because the data is publicly available. It excludes academies, which account for about 60% of secondaries and 20% of primaries in England.
The research adds to growing evidence of the financial struggles faced by a significant minority of schools.
This was highlighted during the General Election campaign as a major issue for voters.
The report also found two-thirds of council schools spent more than their income in 2016-17, while 40% have had balances in decline for at least two years in a row.
“For a significant proportion of schools in England, being able to meet the cost of annual staff pay increases from a combination of government funding and their own reserves looks highly unlikely, even in the short term,” said the report.
Jon Andrews, EPI’s director for school system and performance, said: “We are seeing an increasing number of schools spending more money than they have coming in and our analysis shows that increasing costs on staff are going to add to that pressure, even with the additional funding being delivered by the National Funding Formula. …”
