11+ Admissions

Joining Trinity at an exciting time that’s full of opportunities to get stuck in to new activities and make new friends.
Our induction programme for boys joining at 11+ – which includes our New Boys’ Morning and water sports trips – is designed to ensure that your son has the best transition from his primary or prep school.

With class sizes of around 21 students, teachers will get to know your son quickly and he will always have someone to ask if he has any questions or worries. He will also have Sixth Form mentors to go to if he needs help, who have been through the process themselves.

Applications for entry in September 2024 are now closed. You can register your interest for entry in September 2025 using the button below:

A day in the Life of the Lower School

A day in the life of a First Year student at Trinity School in Croydon. Told through the (mostly!) unedited voices of our entertaining youngest students, we hope it gives you a taster of what’s on offer in the Lower School.

The Trinity admissions journey

From hearing about us to waving your son off on his first day at Trinity, there are six simple stages of our admissions process, outlined in this video. Key dates and other information to help you make your application can be found below.

Trinity fosters a caring atmosphere where boys can flourish and excel.
