The Schools inspector, Ofsted has published its first report reviewing education standards across the East of England.
It's found children in this region have among the lowest chances of attending a good school, with primary schools performing the worst in the country.
The region's secondary schools are also falling behind.
Julie Branch, Headteacher at Holywell Primary School in Cambridgeshire, thinks some schools will struggle to meet Ofsted's standards.
"Getting rid of 'satisfactory' was probably a good idea, although the number of schools becoming 'requires improvement', which is what they've replaced it with because they're not yet 'good', is extremely challenging.
"Some of the issues around the data that they're wanting on the children's progress, and the way that's measured, can feel hard to achieve for some schools but it is right.
"You want your child to be in a good school, schools want to be good and there's a job that needs to be done."
Ofsted has today published its first ever report reviewing education standards in the East, and the region's primary schools in particular have come in for criticism.
The Annual report says that children in the East have a lower chance of attending a good or better school than other areas of the country.
In fact, primary schools in this region are said to be performing worse than any other region in England, with over half of the local authority areas in the East below the national average for good or better primary schools.
Secondary schools are also thought to be struggling, although improvements are beginning to be noticed thanks to a rise in the percentage of good or outstanding schools in the region compared to this time last year.
Finally, the report states that leadership and management of schools are the worst in the country.
Compared to the national level of 82%, only 76% of Eastern schools are said to be led well.
Sean Harford, Ofsted Regional Director for the East of England, said that he was concerned with the findings:
“While secondary schools in this region are closing the education gap with national performance, this cannot be said for primary schools. The picture for primary aged children is dire.
“Despite the relative affluence of the region, primary school pupils in the East of England have one of the lowest chances of attending a good school in the country.
"It cannot be right that nearly 250,000 children are going to a school that is not good enough. Improvements must be made and made quickly if children are to have a better starting chance.
“Leadership and management are also the worst overall in the country. As Regional Director for the East of England I am determined to focus minds through our inspection and improvement work.
"Ofsted inspectors will monitor, challenge and support those institutions that are underperforming and we will not walk away until education standards improve in the region.”
