Comparisons are with secondary schools. Scales run from lower (left) to higher (right) figures. For absence and suspensions lower is better, so their scales run green to red; blue scales describe the school's pupils and staff and aren't good or bad. * Calculated by SchoolScores from the council's or England's schools, weighted by pupils (or teachers, for turnover); other figures are published by DfE.
