Subjects
Results came out for 12 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
Subjects that did worse than the England average: Biology (26% here, 82% across England), Art and Design (6% here, 58% across England), Physics (32% here, 82% across England), Chemistry (32% here, 81% across England).
The small number is how many pupils sat each subject. Subjects with fewer than six pupils 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. 1 of the 3 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.
555 places were empty (53% of the total), so almost everyone who applies gets in. Pupil numbers have fallen by 15% since 2021/22, so places are getting easier to find.
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 (112 offers for 210 places).

The most common needs among pupils getting extra support: emotional and mental health (68), Autistic spectrum disorder (23), Specific learning difficulty (23), Moderate learning difficulty (20), language and communications needs (15), Vision impairment (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 Kemnal Technology College 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 Kemnal Technology College, 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 2 means that once everything below is added up, this school comes out ahead of 2% of secondary schools in England. Results bounce around from year to year, especially in small schools, so we also show a likely range: 1 to 3. 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.
