Therfield School
similar schools
Therfield School is a converter academy in Leatherhead for boys and girls aged 11 to 18. It has 1,075 pupils and room for 1,375. About 20 in every 100 pupils come from a low-income family, a bit fewer than at most schools. We give it 57 out of 100. That puts it in line with schools like it, ahead of 44% of the 50 schools most like it. Ofsted's last grade was good, back in 2024.

What Ofsted found
A shorter visit on 16 May 2024 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.

A level subjects
16 A level subjects had results in 2025. Each figure is the share of students who got an A* to B, next to the average for state sixth forms in England. When only a handful of students take a subject, its figures jump around from year to year.

A levels only. BTECs, T levels and other courses are in the table above. Subjects with fewer than five students aren't published.
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. None of the gaps 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
Open to all. There is no entrance test.
278 places were empty (21% of the total), so almost everyone who applies gets in. Pupil numbers have grown by 5% since 2021/22.
In 2026 every child who applied got a place, so how far away you live didn't matter. That could change if the school gets more popular.
We measure in a straight line from the middle of your postcode to the school. The council measures its own way, and the cut-off changes every year. Use this as a rough guide, and read the council's admissions booklet before you apply.
How places were given out for September 2026. Every child who applied got a place (239 offers for 210 places).
Who goes here
Who a school teaches matters. That is why our score compares it with schools that take in a similar mix of children, not with every school in the country.
Specialist SEND provision. Resourced provision (extra staff and funding within a mainstream school) with 19 pupils, for speech, language and communication.
To get a place in the unit or resourced provision, a child normally needs an education, health and care plan (EHCP) that names the school. Other schools in Surrey with speech, language and communication provision.
The most common needs among pupils getting extra support: emotional and mental health (70), Autistic spectrum disorder (42), Specific learning difficulty (36), language and communications needs (36), Other difficulty or disability (6), SEN support but no specialist assessment of type of need (3).

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 secondary 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.

Compared with schools like it
Our score compares Therfield School with the 50 schools in England whose pupils are most like its own. We match on family income, how many children are learning English, special needs, the neighbourhood, the size of the school and how it admits pupils. Those 50 schools are dotted all over the country, so we don't list them. What matters is where this school sits among them.
Nearby schools with a similar mix of pupils that score higher
Of those 50 schools, these are within 25 km and score at least five points more than Therfield School, nearest first. A school with the same kind of pupils and a higher score is the fairest sign that it gets more out of them.

How the score was worked out
The score is out of 100. A 57 means that once everything below is added up, this school comes out ahead of 57% of secondary schools in England. Results bounce around from year to year, especially in small schools, so we also show a likely range: 47 to 67. Every part is judged against schools with a similar mix of pupils. For small schools we pull each part towards the group average, so one unusual year can't swing the score too far.
