NEW scores that show how schools help pupils progress have led to dramatic changes in their league-table positions.
In a pilot project that ranked 495 primaries, the 50 with the highest "value-added" measures included 21 which did not make the top 50 when ranked by raw scores. Four schools leapt more than 200 places to be ranked among the top 40.
The project, which also looked at 10 special schools, compared children's test scores at age 11 with their scores at seven.
The resulting scores - which will be calculated for English primary schools next year and published alongside raw scores - were presented as a measure with a standard score of 100.
Measures above 100 represent schools where pupils made more progress than the national average; measures below 100 represent those where pupils made less progress.
Th e four that leapt more than 200 places to be among the top 40 for pupil progress were: St Vincent's Catholic primary in Dagenham; Allen Edwards primary in the London borough of Lambeth; Our Lady of the Rosary Catholic primary, Leigh, Lancashire; and St Stephen's Church of England, Bury, also in Lancashire.
The Department of Education and Skills is banding value-added scores so that each school gets graded for adding value that will put its raw score into context. A school in the top 5 per cent nationally will get an A, the next 20 per cent a B, the middle 50 per cent a C, the next 20 per cent a D and the lowest 5 per cent an E.
But there are fears that low grades could stigmatise schools. Professor Peter Tymms, of Durham University, said: "I think value-added measures are important, but I question whether they should be made public. For example, schools which are ranked D will still have made progress. And even if every school is brilliant, there will still be some which are ranked as Es."
The number of schools getting a perfect score in KS2 tests - when all their pupils reach level 4 in English, maths and science - has dropped by one , from 179 last year to 178 in 2002.
Henleaze junior in Bristol has the the biggest year group with a perfect score: all 97 pupils achieved level 4 in the three subjects. South Farnham community junior in Surrey, which enjoyed the largest clean sweep last year, missed out by just one percentage point - 99 per cent of its 124-strong cohort achieved level 4 in English, while all pupils made the grade in maths and science.
The 11 pupils who took the key stage 2 tests at Urchfont Church of England school in Devizes, Devon, achieved the highest average point score of 32.8. The point score for a level 5 is 33.
The most improved school in England was St Barnabas in Manchester, which came out of special measures in 2001 (see below) Bottom of the table was South Borough primary in Maidstone which had its results quashed. Hothfield village primary, Ashford, Kent, had the second lowest results. Hothfield head Liz Akhurst said that the 15 children who were eligible to take the tests last year had been affected by a turnover of staff while they were in Years 2, 3 and 4. She added: "Nine of the children were on the register of children with special education needs. In English, only seven children took the test and when you are talking in percentage terms about that number of children, it is slightly ridiculous."
Richmond-upon-Thames was the most successful local education authority, after the City of London, which has only one school, and the Isles of Scilly, which have four.
The bottom authority was Sandwell, which was 13th from bottom last year.
