Understanding School Catchment Areas & Admission Distances
“Am I close enough to get in?” is the question every parent asks. For most oversubscribed schools in England, your home-to-school distance is the deciding factor after higher-priority criteria (looked-after children, siblings, faith criteria) are applied. This guide explains how the system works and how to use data to improve your chances.
How School Catchment Areas Actually Work
Contrary to popular belief, most schools in England do not have a fixed “catchment area” with defined boundaries. Instead, admission is determined by distance from the school after higher-priority criteria are applied. The “last admitted distance” — the distance of the last child offered a place — is what creates the effective catchment.
This distance changes every year depending on how many families apply and where they live. A school might admit children up to 0.8 miles in one year and only 0.5 miles the next.
Key insight: Three years of admission distance data gives a much more reliable picture than one year. If the furthest distance has been 0.6, 0.7 and 0.5 miles over three years, you should plan based on ~0.5 miles, not the 0.7 outlier.
The Typical Order of Admission Priority
Most non-faith, non-selective schools use this order:
Looked-after children (LAC) and previously looked-after children
Children in care or adopted from care. This is a legal requirement.
Siblings
Children with a brother or sister already attending the school. This is the most common criterion after LAC.
Distance
Children who live closest to the school. This is where the "catchment" effect happens.
Faith schools add religious criteria (church attendance, baptism). Grammar schools use entrance test results. Some schools use “banding” to ensure a balanced intake by ability.
How Distance Is Measured
There are two common methods:
Straight-line distance
Measured “as the crow flies” from your home address (usually the front door) to the school's designated measuring point (usually the main entrance). Used by most local authorities.
Shortest safe walking route
Measured along roads and paths. This produces longer distances and can favour families on different sides of the school. Used by some authorities including parts of London.
Watch out: Check your local authority's policy to see which method they use. A family 0.3 miles away by straight line might be 0.6 miles by walking route — or vice versa. This can determine whether you get a place.
Understanding Oversubscription
A school is oversubscribed when it receives more applications than it has places. The degree of oversubscription varies enormously. Some schools receive twice as many applications as places; others are only just full.
Classpot shows the oversubscription ratio for every school that publishes admission data. A ratio of 3:1 means three families applied for every one place. The higher the ratio, the tighter the admission distance will be.
Schools that are not oversubscribed will admit all applicants. If you are not within distance of a popular school, there may be an excellent but less well-known school nearby that admits everyone who applies.
Tips for Maximising Your School Choices
- List the maximum number of preferences your local authority allows (typically 3–6).
- Include at least one “safe” school where you are very likely to get a place.
- Check three years of admission distances, not just one — one year can be an outlier.
- Remember that siblings get priority. If your oldest gets in, younger children are much more likely to.
- Don't assume you'll get your first choice — list preferences honestly in the order you want them.
- If you live equidistant between two good schools, the less popular one may have a wider catchment.
- Visit schools during open days — data tells part of the story, but the feel of a school matters too.
Frequently Asked Questions
How do I find a school's catchment area?
Most schools don't have a fixed catchment. Check the “last admitted distance” in previous years. Classpot shows oversubscription data and applications-to-places ratios for every school.
Does living in the catchment guarantee a place?
No. The admission distance changes every year. Living within last year's distance does not guarantee a place this year if more families apply from closer.
How is the distance to school measured?
Most authorities use straight-line distance. Some use shortest walking route. Check your local authority's admission policy.
Can I move house to get into a catchment area?
You can move genuinely, but temporary moves to secure a school place are considered fraudulent and can lead to the offer being withdrawn.
