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.

Getting a place

Open to all. There is no entrance test.

Nearly full1,707 pupils for 1,770 places, 2024/25
96% full

Fewer than one place in twenty is empty, so in most years more families apply than there are places. Living close by, or already having a child here, makes a real difference. Pupil numbers have stayed about the same since 2021/22.

Will my child get a place?

The last child to get a place lived 6.9 miles away in 2026. Children in care, brothers and sisters of current pupils, faith and other priority groups are placed first. After that, the closer you live, the better your chances. Type in your postcode to see how far away you are.

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. More children applied than there were places. The last place went to a child living 6.9 miles from the school. Living closer than that didn't guarantee a place, but living much further away meant missing out that year.

Specialist SEND provision. Resourced provision (extra staff and funding within a mainstream school), for specific learning difficulties.

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 Wiltshire with specific learning difficulties provision.

The most common needs among pupils getting extra support: emotional and mental health (70), Specific learning difficulty (65), Autistic spectrum disorder (54), Moderate learning difficulty (34), language and communications needs (23), Physical disability (6).

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.

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 St John's Marlborough 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.

How the score was worked out

The score is out of 100. A 69 means that once everything below is added up, this school comes out ahead of 69% of secondary schools in England. Results bounce around from year to year, especially in small schools, so we also show a likely range: 60 to 76. 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.

Questions parents ask

Is St John's Marlborough a good school?

Yes, going by the figures. St John's Marlborough scores 69 out of 100. That is above schools that take in a similar mix of pupils, and ahead of 68% of the 50 schools most like it in England. The score could fairly be anywhere from 60 to 76, so a few points either way between schools doesn't mean much.

What is St John's Marlborough's Ofsted rating?

Ofsted rated St John's Marlborough not judged at its last full inspection on 11 February 2025.

How good are St John's Marlborough's GCSE results?

Its Attainment 8 score, which is the average grade across a pupil's best eight subjects times ten, was 50.9, against 46.8 for England. In each subject, pupils here finished about half a grade ahead of children across England who started secondary school at the same level.

How many pupils does St John's Marlborough have?

1,692 pupils aged 11 to 18 were on the roll in January 2026. It has 1,620 places, so it is 104% full.

Is St John's Marlborough oversubscribed, and how far away can you live?

Yes. For September 2026 the last place went to a child living 6.9 miles away. Children in care, brothers and sisters of current pupils and other priority groups come before distance, so the cut-off moves every year.

What is attendance like at St John's Marlborough?

Pupils were in school 91.4% of the time in 2024/25. Similar schools in England managed 91.4%. 23% of pupils missed at least a tenth of the year.

The average class had 22.7 pupils in January 2026. Across England it was 22.8. 19% of classes had more than 30 pupils.

Does St John's Marlborough have specialist SEND provision?

Yes. It has resourced provision (extra staff and funding within a mainstream school) for specific learning difficulties. To get a place there, a child normally needs an education, health and care plan (EHCP) that names the school.

Does St John's Marlborough have a sixth form?
