Teaching & academics
The results speak plainly: an average Attainment 8 of 72.3 against a national figure of 46.9, and 98 per cent of pupils securing at least a grade 5 in English and Maths where the national average is 47 per cent. This is a school where strong academic outcomes are the norm rather than the exception. The pupil-to-teacher ratio of about 20.1 reflects a large school, but Ofsted's Outstanding rating for quality of education suggests teaching keeps pace.
