You also need to wear your house lanyard and skirts/trousers. Different subjects also offer equipment you need, such as red aprons for DT, PE kit, trainers/football boots and calculators for maths.
The school has a variety of enrichment, including music, art and dance. Many students attend these to broaden their knowledge and make new friends. There are also programs, such as Antibullying Ambassadors, which have won the Diana Award. There are 4 houses, Neptune, Jupiter, Saturn and Mars. These houses have competitions such as sports day, football and House Games. Every year a music show is hosted, and there is a club where you can design clothes for the school show, lead by Miss Oakley. Teachers have class codes, e.g Miss OakleyâÂÂs code is SOY.
The school was built in August 25, 1931 by the Mill Hill Schools Foundation. The current school was created as a merger between Moat Mount Comprehensive and Orange Hill school in Burnt Oak after the latter was closed. Orange Hill had originally been a grammar school and Moat Mount a secondary modern before the ending of the grammar school system in the Borough of Barnet in the early seventies. Moat Mount Comprehensive had a sixth form of up to 80 pupils in the mid-Seventies and a total school population of around 970 pupils. In contrast, the school was notable for its "Good" report established by Ofsted. It has stated how mature the pupils were and how teachers were experts in their roles.
It is for students aged 11 to 18. The school has 1,684 pupils as of the 2023/2024 school year. As of 2025/2026, the school has 1,538 pupils. There are 500 sixth formers. The current headteacher is Andy Stainton, who has succeeded Geoffrey Thompson. Thompson has retired in 2019, which caused him to depart the school.
Selection of GCSE option subjects takes place in Year 9. The Science course leads to double GCSE certification. For English, students have the opportunity to study both English Language and English Literature to GCSE level. ICT and Religious Education can lead to a full or a half GCSE. Languages are chosen in the end of Year 8.
