Choosing a private school is one of the biggest decisions a family makes, and the highest-ranked school is rarely the best school for a particular child. This guide walks through how to weigh the factors that actually matter, in the order they matter.
Start with your child, not the rankings
A school that suits a confident, exam-focused child may be wrong for a creative or late-developing one. Before comparing any schools, write down what your child actually needs.
Useful things to be honest about:
- Pace. Do they thrive under pressure, or shut down? A highly selective school is a gift to some children and a seven-year grind for others.
- Size. A large school offers more subjects, more teams and more chance of finding their people. A small one offers more attention and fewer places to get lost.
- Structure. Some children need clear routine and firm boundaries; others need room.
- Strengths outside the classroom. If sport, music or drama is central to who they are, that should weigh heavily.
- Any identified needs. If there is dyslexia, autism, ADHD or another need in the picture, that reshapes the whole list — see dyslexia and choosing a school and autism, ADHD and school choice.
The most common mistake is choosing the school you would have wanted, rather than the one this child needs.
Get the money settled first
It is worth doing the arithmetic before you fall in love with anywhere, because the emotional cost of withdrawing a settled child is high.
Work out the total across the full run of years — including sixth form, all children, and annual increases — rather than year one. Then add the extras, which routinely add a meaningful amount on top of the headline fee: uniform, trips, music lessons, exam entries and transport. See the hidden costs of private school.
Two further points:
- Since January 2025, VAT applies to private school fees, which changed fee levels unevenly across the sector.
- Means-tested bursaries are widely under-used, and must be applied for during the admissions round rather than after an offer. See bursaries and scholarships and how to pay private school fees.
If the fees only work on the optimistic version of your finances, a less expensive school you can sustain is almost always the better outcome. There is a wide range — affordable private schools covers what the lower fee tiers buy.
Read the results properly
Headline results measure who a school admits at least as much as how well it teaches.
- Attainment measures (percentage at grades 9-7, or A*-B) reflect the intake heavily. A selective school will always look strong.
- Progress measures get closer to what the school adds.
- Small cohorts are volatile. Look at three years, not one.
- Check the department you care about, not the school average. Subject variation within a school is often larger than variation between schools.
Our guides to reading exam results and reading league tables go into this in detail. For the official state-sector data, the Department for Education publishes Compare School and College Performance.
Check inspection reports — and their date
Most association independent schools are inspected by the Independent Schools Inspectorate; others by Ofsted, whose reports are published on the Ofsted reports site.
Both inspectorates have changed their frameworks recently, so older reports use retired grading vocabulary. A rating from several years ago describes the school as it was, quite possibly under a different head. Read the text rather than the label — see the new Ofsted report cards explained and ISI vs Ofsted.
Weigh the commute honestly
The factor most consistently underestimated at the point of choosing, and most consistently regretted later. Measure the journey at the real times, in both directions, and count the extra trips — matches, concerts, the child who is unwell at eleven in the morning.
The hidden cost is co-curricular: if your child cannot stay for the play or the second-team fixture because the coach leaves at half past four, you are paying for a programme they cannot use. See how far is too far for the school run.
Then visit — and visit properly
Everything that matters after the longlist stage is visible on a visit and invisible in data.
- Go on a normal school day if you possibly can, not only to the Saturday open morning. They are different places.
- Watch the children, not the tour. Do they look at ease with the adults? What happens in the corridor between lessons?
- Watch how staff speak to a child who is struggling. This tells you more than anything said to you directly.
- Trust the atmosphere. Parents are usually right about this and then talk themselves out of it.
Our guide to making the most of an open day has a full checklist.
Questions worth asking
- What happens to a child who finds a subject difficult?
- What is staff turnover like, and who has left recently?
- How do you communicate with parents, and how quickly do you respond?
- Where do your leavers actually go, and what proportion of the year group is that?
- What does a typical week look like beyond lessons — and can a day pupil access it?
- How many pupils are on the learning support register?
- What would you say this school is not good at?
That last question is the most revealing. A head who answers it honestly is worth a great deal.
Build a realistic shortlist
Apply to more schools than feels necessary, spanning a range of selectivity. The most common cause of a difficult offer day is a list of four schools all pitched at the same demanding level.
Registration deadlines vary and some are very early — see the independent school admissions timeline.
It is also worth checking the free alternatives properly. If you are in or near a selective area, a grammar school place costs nothing — see private school vs grammar school and grammar schools by county.
Putting it together
Shortlist on results, fees and inspection outcomes; then decide on the visit. You can filter by location, fees, gender, boarding and SEN provision on the school search, browse by area — for example private schools in Surrey, Hertfordshire or schools in Birmingham — and put your final three side by side on the comparison tool.
