There was continuing growth in the numbers of day pupils - especially girls - and a boom at nursery and primary levels.
There was good news on the academic front too, with half of all GCSE entries gaining an A or A* and more than one in three A-level entries winning an A.
However, James Sabben-Clare, headmaster of Winchester College and chairman of the Headmasters' and Headmistresses' Conference, attributed the improvement to the fact that it was had got easier to do well in A-levels. He said: "A-levels have changed over the years. The content has in most, probably all, subjects been reduced."
