Opponents of selective education were celebrating this week after comprehensives outperformed grammar schools in new "value-added" tables of achievement beween the ages of 14 and 16.
Only three grammars featured in the top 100 secondaries ranked according to progress made by pupils during key stage 4.
The results contrast vividly with the key stage 3 league tables, published last month, which ranked schools by pupils' progress from 11 to 14. In those, grammars filled 44 of the top 49 places - and dominated national media coverage.
David Chaytor, a Labour backbench MP and leading comprehensive campaigner, said: "The stunning performance of our leading comprehensive schools should be the final nail in the coffin of the case for selective secondary education."
Value-added measures attempt to gauge how much a school improves a pupil's performance. They compare a pupil's results with those of children across the country who start out with similar ability levels.
It is still difficult, though, to get a complete view of a secondary school's contribution to a pupil's education throughout the years running up to GCSE as there is not yet a national 11-16 value-added measure.
The Government has attempted to move towards this with a measure based on a smaller number of schools. It has produced a separate list of the 133 secondaries with the best value-added scores at key stage 3, and then ranked them by how much extra value they add during key stage 4.
Again, comprehensives appear to do well on this measure. David Miliband, the schools minister, pointed out that they filled 97 of the top 133 places.
However, supporters of selection by ability will also point out that 27 of the 133 were grammar schools. As grammars account for just 166 of the country's 3,700 secondaries, this is a strong representation.
Leading this table was Lordswood girls' school, Birmingham, where Jane Hattatt, the head, described the result as a vote of confidence in comprehensive education.
Sir John Cass school, in Stepney, east London, had the highest value-added score overall at key stage 4. It also was the country's most improved secondary. Skegness grammar in Lincolnshire topped the KS3 value-added table.
Fir Vale school, Sheffield, which was forced to close and re-open only five years ago under the Government's controversial Fresh Start policy had the country's seventh best value-added score at key stage 4.
Thomas Telford school, the city technology college in Telford, Shropshire, again had the best results among comprehensives in the traditional, non-value-added tables. For the fourth year running, all of its pupils achieved the benchmark five or more GCSEs at C or better (or equivalent).
This year all got at least nine passes at C or better.
But the tables were again denounced by some of those near the bottom, many of which are already lined up for closure.
Ramsgate school in Kent finished bottom: just 4 per cent of its pupils achieved five or more passes at A* to C.
Carol Dibbs, the new executive headteacher at High View school in Derby which came equal second from bottom on a score of 7 per cent, said the tables were a "kick in the teeth" for staff who had worked hard to take the school out of special measures.
