Norfolk and Suffolk have jumped above the national average for GCSE exam results in provisional league tables released this morning.
This is the first year the government has used a new measure - known as Progress 8 - to judge how schools are performing.
Progress 8 aims to measure how well pupils progressed between the end of primary school and the end of secondary school, compared to pupils in other schools who got similar results at the end of primary school.
The higher the Progress 8 score, the better schools and local authorities have performed.
Norfolk and Suffolk both had a provisional average Progress 8 score of 0.02, compared to -0.03 across state funded schools in England. Cambridgeshire's score was 0.12.
In Norfolk, Hethersett Academy was the top performing school, with a score of 0.68, which was classified as 'well above national average'.
Wymondham College, on 0.53, was the only other Norfolk school in the same position.
City Academy Norwich (-0.52), the Hewett Academy (-0.54) and King's Lynn Academy (-0.54) were all listed as 'well below average'.
The top-rated schools in Suffolk included Stradbroke High (0.36), Sir John Leman High (0.34) and East Point Academy (0.26).
Ormiston Denes Academy, in Lowestoft, was rated 'well below average', with a score of -0.66.
The final league tables will be released in January 2017, and will take account of the results of exam appeals.
