The school is organised horizontally on a Year basis. There is a Learning Co-ordinator with repsonsibility for Year 7 (and primary-school liaison), Learning Co-ordinators for Year 8, 9, 10 and 11, and a post-16 education Learning Co-ordinator (Year 12 and 13). All work closely with the Head and the Management team to ensure continuity and consistency of approach in the implementation of school policies, arrangements and general pupil welfare. Pupils in Year 7 are taught in mixed ability groups, apart from pupils with Additional Learning Needs who have their own specialist provision which includes a degree of integration. From Year 8 onwards, pupils may be placed in ability sets in some subjects, whilst remaining in their normal forms for others. Pupils' work is monitored continually and formal examinations are held annually. Pupils are registered in mixed-ability groupings in all Years; Tutorials, Personal and Social Education and some subject lessons are also conducted in mixed-ability groups. On entry into Year 10, pupils choose subjects which will be the basis of a two-year programme of study leading to an external qualification.
