Out-of-borough is allowed in many cases, but it is not neutral
Parents often discover grammar schools by looking beyond a borough boundary. That can be sensible: selective routes do not always line up neatly with council borders, and some families live close to schools in a neighbouring area.
The application process still needs careful handling. You normally apply through the local authority where you live, even if the schools are in another local authority area. The receiving school or authority then applies its admissions rules.
Example
A family living outside Bexley may still be able to register for the Bexley Selection Test and name a Bexley grammar school on the CAF. But if the child reaches the selective standard, the school-level policy still matters. Some places may be affected by distance, priority groups, sibling rules, or score ranking.
The same pattern appears in other areas such as Kent, Slough and Buckinghamshire: the boundary does not always block an application, but it can shape how realistic the school is.
What to check
- Which local authority receives your CAF.
- Whether you need to register separately for the test.
- Whether the school admits out-of-area applicants.
- Whether distance or priority area rules have affected past allocations.
- Whether the journey is practical every day, not just on test day.
- Whether your current address must meet any date or evidence rule.
Use the school policy, not borough folklore
Out-of-area admissions are an area where rumours spread quickly. Read the current admissions policy for the named school and the local authority guidance for the year of entry, then test the journey on the school map. A school can be technically open to wider applicants and still be very hard to reach in practice under its allocation rules.
