What Ofsted found
A shorter visit on 21 October 2022 found nothing to change the school's grade. Read the report on Ofsted's website.
Good overall. A shorter follow-up visit found nothing to change that. 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.

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
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 Hertfordshire 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 council school accounts, year to March 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.
