Admissions
How to apply (opens in a new tab)
You apply through your council, not the school - even for academies and free schools. Applications close on 31 October, the year before starting.
Hampshire admissions (opens in a new tab)
The council publishes the oversubscription criteria and last year’s offer distances, which is the closest thing to knowing your chances.
If you are refused a place (opens in a new tab)
You can appeal, and you can join a waiting list at the same time. Accept whatever offer you get first - declining it can leave you with no place at all.
This school’s own admissions (opens in a new tab)
Schools that set their own criteria - faith schools, grammars, academies - publish them on their own site.
