Secondary School League Tables: Key

The average point score at GCSE is arrived at by giving recognition to all qualifications gained by a pupil. An intermediate GNVQ is awarded four times as many points as an A* to C grade pass at GCSE.

The value added score is arrived at by predicting what pupils should achieve at 16 when they arrive at the school at age 11. If ­ on average ­ pupils improve upon their predicted performance, the school will be awarded a score of more than 1,000. If they slip back, it will get less than 1,000.

The average point score for A-level again takes account of all qualifications gained by pupils ­ including key skills. The majority of the weighting is for A-levels though with 120 points for an A grade, 100 for a B, 80 for a C, 60 for a D, 40 for an E. An AS-level is worth half an A-level.
