Why one rating is not enough
Headline ratings simplify rich information and can be out of date by the time you move. To judge schools well, combine four kinds of evidence: what inspection and performance data do and do not show, how admissions actually work where you are buying, the practical fit of distance, travel and wraparound care, and a short evaluation loop that tests likelihoods and back‑up paths.
This article is written for the UK. It highlights key operational differences across England, Scotland, Wales and Northern Ireland so you can check the right primary sources for your area.
Key concepts you will use
Step by step: how to judge schools well
A short evaluation loop that leads to a sound decision
Use a focused loop to test likelihoods and set contingencies. Do not chase the highest single rating. Treat inspection and performance as inputs alongside admissions mechanics and daily practicality.
Worked examples to show the mechanics
These examples illustrate how to apply the steps. Replace placeholders with your local policies and actual distances before using.
4.1 Primary place likelihood for two streets in one town
Assumptions: a town in Hertfordshire, England. School X is a community primary. Oversubscription after looked‑after children and siblings is distance, measured by straight‑line GIS. Random allocation is used only when two distances are identical. Waiting list re‑ranks under the same criteria. PAN 60.
Last year the final on‑time offer distance was 0.42 miles. This year’s demand is unknown.
Inputs: House A is 0.37 miles by straight line. House B is 0.44 miles by straight line. Neither has sibling priority and both apply on time.
Mechanics: after protected priorities, the rank sorts by straight‑line distance. House A ranks ahead of House B. If 60 offers fill at 0.40 miles this year, House A is offered. House B is refused and placed on the waiting list. The waiting list re‑ranks as new applications arrive. Joining siblings or moves inside 0.40 miles can push House B down.
What to record: distance method, tie‑break, and the fact that last distance offered is descriptive, not guaranteed. If House B later moves to 0.39 miles, provide proof of new address per the policy and request re‑ranking. Do not expect transport eligibility, which uses different walking‑route rules.
4.2 Secondary comparison where inspection profiles match but travel and Progress 8 differ
Assumptions: two academies have recent Ofsted report cards with similar profiles across evaluation areas and no safeguarding concerns. Journey options differ.
School M: Attainment 8 equals 49.0. Progress 8 equals +0.30. Bus is 26 minutes door to door. Walk is 32 minutes.
School N: Attainment 8 equals 51.5. Progress 8 equals −0.05. Bus is 14 minutes. Walk is 18 minutes. Data are three‑year averages from the Department for Education performance service.
Reasoning: if you value progress more than raw attainment, School M’s +0.30 suggests stronger value‑added. But the shorter, more reliable commute to School N may reduce daily friction and support punctuality and participation. Combine this with curriculum fit and extracurriculars, then run admissions likelihoods for each school’s criteria and distance method before ranking preferences.

Glossary
- Attainment 8
The average points score across eight approved GCSE‑level qualifications.
- Progress 8
A value‑added measure from end of primary to GCSE across eight subjects.
- Catchment area
A defined priority area used by some admission authorities. It confers priority when oversubscribed but is not a guarantee of a place. Always see the school’s policy.
- Report card (Ofsted)
Since 2024, inspection outcomes for state‑funded schools in England are presented across evaluation areas rather than as one overall grade.
- SEAG Entrance Assessment
The post‑primary transfer test used by many Northern Ireland grammar schools within oversubscription criteria.
- Statutory walking distance
For transport eligibility in England, generally 2 miles under age 8 and 3 miles age 8 to 16 measured by available walking routes. This is separate from admissions distance.
Verified callouts
Catchment areas are not guarantees and can change each year
Catchment or priority areas give higher priority only when a school is oversubscribed. They do not guarantee admission and arrangements can change annually. Always read the current, determined admission arrangements for the intake year and the school’s own definition of catchment and distance.
Distance method is set locally and affects priority
Distance can be measured as straight‑line or by walking route and from specific address and school points. Your mapping app may not match the authority’s GIS. Check each school’s policy before estimating likelihood.
Inspection outcomes are snapshots
Inspection findings describe quality and safeguarding at the time of inspection and can change. England’s Ofsted now reports via evaluation‑area report cards. Read the whole report, not just headlines.
