Pupils and staff are all highly ambitious in their pursuit of aspirational academic outcomes. Outcomes for pupils at both GCSE and A level are among the highest in the country.[34]
Warmth
Pupils are unwaveringly encouraging and supportive of each other at this outstanding school. Pupils of all ages have a real love for the school.[34]
Pastoral care
This ensures that pupils receive a high level of support in response to any concerns they may have.[34]
Behaviour
Pupils' behaviour is unfailingly positive.[34]
Learning support
They use this to plan and teach lessons that meet pupils' individual needs, including those with special educational needs and/or disabilities[34]
Enrichment
They are eager to come to school each day, as there is so much to get involved with.[34]
Pupil voice
All students are expected to be involved in leading and managing the many varied and interesting clubs on offer. Older students ensure that younger pupils are given important pupil-led opportunities to contribute their voice[34]
Independence
