What the school inspection says

“Pupils are happy and safe. They behave exceptionally well in lessons and around the school. This means that no learning time is wasted. Relationships between staff and pupils are excellent … Pupils attend a wide range of additional clubs and activities. In the sixth form, there is an extensive enrichment programme. This includes activities such as debating, introductory courses to Russian and Italian and completing an accredited award in science … The curriculum is ambitious for most pupils. However, in Years 7 and 8, a small number of pupils do not study modern foreign languages as part of their usual weekly timetable. This limits the breadth of the curriculum for these pupils in comparison to their peers. Behaviour and attitudes and sixth-form provision are deemed to be outstanding.”
