In the inspectors' and the school's words

Academic
The curriculum is ambitious and pupils enjoy being challenged.[36]
Pastoral care
Leaders ensure staff are well trained to support pupils pastorally. Sixth-form students have been trained as mental health ambassadors. These include a support hub, specialist staff and work with external agencies when required.[36]
Behaviour
The behaviour of pupils is exemplary both in lessons and around the school site.[36]
Learning support
This helps these pupils to access the full curriculum effectively. leaders have not embedded systems to check that strategies are effective or being consistently used by staff.[36]
Enrichment
They have access to a broad curriculum and a large range of wider opportunities.[36]
Pupil voice
They seek to develop inquiring, informed and compassionate young leaders.[36]
Structure
Leaders have high expectations for pupils’ conduct.[36]
Performing arts
Opportunities range from sport and music activities, jewellery club and the ‘zen-den’[36]
Visual arts
The examples of artwork on show in the school gallery typify the high-quality outcomes pupils produce. in art, pupils receive regular targeted feedback on their work, and sixth-form students take part in weekly peer review sessions.[36]
