Joining St John’s

Boys normally join St John's at 3+ in the Nursery or at 4+ in Reception. We also have a smaller intake at 7+ with boys going into Year 3. Other vacancies may occur from time to time in other years and particularly at 11+.

Admission at 3+ and 4+ is by a simple assessment designed to ensure that each boy has the potential to flourish within the environment and culture of St John’s. Boys who join us in the Junior Department of the Prep school at seven are assessed with written tests and an interview.

The Headmaster would be delighted to welcome you for an individual tour of the school. Please contact the school office on 020 8866 0067 or email
