Most local schools are failing government's new standards at KS2, league tables show - see the results for your child's school

Most schools fell below the newly-created floor standard which demands 65 per cent of pupils reach the required levels in reading, writing and maths.

And the Dorset County Council area was named as one of the bottom five in the country with just 45 per cent of 11-year-olds making the grade.

It was ranked 148th out of 152 local authorities with Poole and Bournemouth at 74th and 75th respectively with 54 per cent each and Hampshire in 28th place with 59 per cent. The top authority in the country was Kensington and Chelsea at 70 per cent.

The tests have been widely criticised with parents warned to ignore the results due to "chaotic" changes to testing.

Just 53 per cent of pupils across the country reached the required standard compared to 80 per cent in last year's less rigorous tests.

In the run up to and during the tests, teachers and heads complained that the new papers had been set at too high a level and that not enough information had been made available.

General Secretary of the National Association of Head Teachers, Russell Hobby, said: "The pass mark for the test was set at a ridiculously high level.

"We have just failed half the children in the country and yet Ofsted is saying nearly 90 per cent of schools are good or outstanding.

"Pupils were doing what they should have been doing in the early years of secondary school. Some of the grammatical stuff was the same level as GCSE English."

He added: "This data is not worth the paper it is written on. The government itself has said that it cannot be used to trigger interventions in schools."

But School Standards Minister Nick Gibb said the introduction of a new curriculum had raised expectations and ensured "pupils become more accomplished readers and are fluent in the basics of arithmetic, including times-tables, long division and fractions."

In Dorset, the top performing school was Lulworth and Winfrith at 89 per cent with Bere Regis at the bottom with just seven per cent.

Baden Powell and St Peter's was top in Poole (69 per cent) with Branksome Heath at the bottom (24 per cent) and St Katharine's and St Mark's in Bournemouth jointly topped the table with 71 per cent. Heathlands was at the bottom with 15 per cent.

New Forest schools performed better with Burley Primary at the top with 93 per cent and Sopley at the bottom with 31 per cent.

Councillor Deborah Croney, Cabinet Member for Learning, Skills and Children’s Safeguarding at Dorset County Council, said: ""Dorset schools continue to do well in reading but the changes to assessment of writing nationally caused anomalies which make this years writing outcomes unreliable and this disproportionately impacted on Dorset’s overall figures.

"We are working to improve maths and there has been exciting work across Dorset with the Teaching Schools Alliance and Maths Hubs, including the Singapore Maths Project.

"These new strategies are being implemented in schools and will further improve maths outcomes.”

In Poole, councillors are celebrating after moving up from second bottom in the country last year to above the national average.

Cllr Mike White, cabinet member for children, said: "This improvement represents the strong partnership between the council and local schools."
