similar schools
St Osmund's Church of England Middle School is a converter academy in Dorchester for boys and girls aged 9 to 13. It has 714 pupils and room for 720. About 17 in every 100 pupils come from a low-income family, far fewer than at most schools in England. We give it 55 out of 100. That puts it in line with schools like it, ahead of 42% of the 50 schools most like it. Ofsted's last grade was good, back in 2022.

What Ofsted found
Ofsted's last full inspection was on 5 July 2022, back when it gave schools one overall grade. Read the report on Ofsted's website.
Good overall.
This inspection is more than 4 years old. When Ofsted next visits, the school will get a report card instead of one grade.

There are no progress figures for 2025. That year group missed their Year 2 tests during Covid, so there was no starting point to measure from. Progress figures come back with the December 2026 results. Tests were cancelled altogether in 2020 and 2021.
† These results are for St Osmund's Church of England Middle School, the school this one replaced in March 2020. Same building and the same children. It got a new registration number, usually because it joined an academy trust.
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. 2 of the 4 gaps are 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 the end of primary school, 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. As a Church of England school it may put families of that faith first. Check the school's own admissions rules.
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.
The last child to get a place lived 4.5 miles away in 2026, 1.2 miles away in 2025, 1.2 miles away in 2024. 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 4.5 miles from the school. Living closer than that didn't guarantee a place, but living much further away meant missing out that year.

The distances are the council's own, usually measured in a straight line from home to the school gate. If the distance is getting shorter each year, the school is getting harder to get into. See which councils we have this data for.
What a home within 1.2 miles of the school costs
Every home sold within that distance of the school (the typical cut-off over the last three years), of any type, from HM Land Registry records. If homes here cost more than the district average, that is the price people pay to live close enough to get in.
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.
The most common needs among pupils getting extra support: Autistic spectrum disorder (50), emotional and mental health (32), Specific learning difficulty (23), language and communications needs (11), Other difficulty or disability (10), Hearing impairment (7).

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 St Osmund's Church of England Middle School with the 48 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 48 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 55 means that once everything below is added up, this school comes out ahead of 55% of secondary schools in England. Results bounce around from year to year, especially in small schools, so we also show a likely range: 34 to 73. 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.
