Welsh secondary schools ranked by score

This table, produced by BBC Wales, ranks all secondary schools in Wales by the total score they were given by the Welsh government.

It's an assessment of a school's performance in the academic year 2010-11, where the lowest scores represent the best performance.

The scores were derived by assessing school performance within four categories including GCSE results and attendance.

Within each category, a school's score is modified to take into account the percentage of pupils eligible for free school meals.

Most of the categories also take into account progress over time, to reward schools that are making improvements in performance.

The scores are used by the Welsh government to rank the schools into five bands.

The best possible score was 11 and the worst possible score was 44.
