Glenthorne High School
similar schools
Glenthorne High School is a converter academy in Sutton for boys and girls aged 11 to 18. It has 1,754 pupils, 196 more than it has places for. About 14 in every 100 pupils come from a low-income family, far fewer than at most schools in England. We give it 93 out of 100. That puts it well above schools like it, ahead of 66% of the 50 schools most like it. Ofsted visited in January 2026 and gave it a report card, which is below.

Results came out for 22 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.
Strongest subjects
The small number is how many pupils sat each subject. Subjects with fewer than six pupils aren't published.

A level subjects
21 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.
Strongest A levels
Every A level subject against England, 2025
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. 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
Open to all. There is no entrance test.
The school is full, with 139 more pupils than it has places for. More families apply than can get in, so things like how close you live and whether an older brother or sister is already here decide who gets a place. Pupil numbers have grown by 7% since 2021/22, so places are getting harder to come by.
How places were given out for September 2026.
What parents say
From Ofsted's Parent View survey: 210 parents answered in the year to 6 April 2026. Parents choose whether to fill it in, and many only do so when an inspection is coming, so don't read too much into small differences. The England figures are the average for secondary schools with enough answers to publish.
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 22 pupils, for autism.
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 Sutton with autism provision.
The most common needs among pupils getting extra support: Autistic spectrum disorder (99), Specific learning difficulty (53), emotional and mental health (26), language and communications needs (16), Moderate learning difficulty (13), Physical disability (8).

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 Glenthorne High 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 Glenthorne High 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 93 means that once everything below is added up, this school comes out ahead of 93% of secondary schools in England. Results bounce around from year to year, especially in small schools, so we also show a likely range: 90 to 95. 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.
