IGCSEs don't count towards Attainment 8, so it understates many independent schools.

In the inspectors' and the school's words

Academic
Leaders set high academic expectations for pupils.[19]
Warmth
Leaders actively promote the school’s aims and ethos so that its community is welcoming and inclusive. Pupils maintain positive, friendly and supportive relationships with each other.[19]
Pastoral care
The pastoral needs, mental health and emotional wellbeing of pupils are carefully, collectively and individually prioritised. Full-time nurses manage the medical centre and are supported by well-trained counsellors.[19]
Behaviour
Leaders reinforce positive behaviour so that pupils behave well. As a result, bullying issues are rare.[19]
Learning support
Pupils who have SEND make good progress from their starting points and achieve in line with their peers in their GCSE and A-level examinations.[19]
Enrichment
Leaders provide a stimulating and varied programme of extra-curricular activities which are well attended by pupils.[19]
Pupil voice
Sixth-form pupils lead the school parliament which votes on issues directly raised by pupils. As a result, leaders have increased the number of water fountains and revised school menus.[19]
Independence
some teaching is less effective because it limits pupils’ engagement and participation and opportunities for them to think and learn for themselves.[19]
Collaboration
Pupils have a secure understanding of the school’s motto to ‘work well and be happy’. Sixth-form pupils provide mentorship to younger pupils, such as helping those in Year 7 to manage their commitments and time effectively.[19]
Structure
They seek to ‘catch the good’ so that pupils’ kind and respectful behaviour is recognised. Staff implement the behaviour policy fairly and consistently.[19]
