Ofsted says contextual value added (CVA) scores - taking into account external factors such as poverty - are the best measure of education quality.
But it adds that absolute CVA values or rankings using them have no meaning because of the way they are calculated.
The Department for Children, Schools and Families produces tables of the schools with the highest CVA values.
A spokeswoman for the DCSF said: "It is not our standard practice in official statistics to rank schools, either by their raw grades in national curriculum tests and other qualifications, or by their CVA scores.
