Clarendon School
Clarendon School is a special academy in Twickenham for boys and girls aged 4 to 16. It has 164 pupils, 4 more than it has places for. About 42 in every 100 pupils come from a low-income family, far more than at most schools in England. Ofsted's last grade was outstanding, back in 2024.

What Ofsted found
A shorter visit on 25 April 2024 found nothing to change the school's grade. Read the report on Ofsted's website.
Outstanding overall. A shorter follow-up visit found nothing to change that, although the inspectors did raise some concerns, so a full inspection will follow. The last full inspection was before September 2019, which is as far back as Ofsted's public records go, so we can't show its date or the grades for each area.

Subjects
Results came out for 1 GCSE subjects in 2025. Each figure is the share of pupils who got a grade 5 or better, next to the average for state secondaries in England.
Subjects that did worse than the England average: Art and Design (7% here, 58% across England).
The small number is how many pupils sat each subject. Subjects with fewer than six pupils aren't published.

Year 6 results (SATs), summer 2025
13 children took the tests. Here is how they did against every state primary in England. With a year group this small, a couple of children can move the percentages a long way.

There are no progress figures for 2025. That year group missed their Year 2 tests during Covid, so there was no starting point to measure from. Progress figures come back with the December 2026 results. Tests were cancelled altogether in 2020 and 2021.
† These results are for Clarendon School, the school this one replaced in October 2016. Same building and the same children. It got a new registration number, usually because it joined an academy trust.
Does every child do well here?
A good school does well by every child, not just on average. Each row compares two groups of pupils here. The grey marks show the same two groups across England. Every gap at this school is smaller than the gap across England. When a group has fewer than about ten pupils, its figures jump around a lot from year to year.
At GCSE, 2025
At the end of primary school, 2025
Low-income means the child has had free school meals at some point in the last six years. A group's figure isn't published when it has fewer than six pupils.
Getting a place
Admissions policy not published.
Each council publishes its own figures on how many families applied and how far away the last child to get a place lived. We are adding councils one at a time. If you have a link to Richmond upon Thames council's admissions booklet, send it to us.

Staff and money
From the government's count of school staff in November 2025 and the school's published accounts.
Money
From the academy accounts return, year to August 2025. The per-pupil figures are compared with other special schools in England that report their accounts the same way.
Reserves are the money left over at the end of the year, kept back for emergencies and big projects. Being in the red year after year is a warning sign. Very large reserves can mean money sitting in the bank instead of being spent on today's pupils. Academy figures are rounded to the nearest £1,000 and include a share of any money the trust holds centrally.
The area around the school
Crime figures come from police.uk. The police record each crime at the nearest of a fixed set of map points rather than the exact spot, so “within 500 m” is only rough. House prices are from HM Land Registry sales nearby over the last two years.
