The admissions process at Wycombe Abbey is competitive, attracting around 300 applicants for 80 places at 11+, 160 for 20 places at 13+, and 190 for 20 places at 16+. The school crafts its own exam papers rather than using Common Entrance and sixth form applicants need at least six grade 9-7s at GCSE, with 9-8s in chosen A level subjects. While academic excellence is important, the school values bright, curious, and kind students willing to take risks and work hard. Roughly 9% of students come from state primary schools and 19% international students. Prospective students are encouraged to visit the school through open mornings and coffee mornings. The 11+ process begins in Year 5 with registration closing on 1st June of the previous year. The first stage involves a CAT4 test, assessing verbal, quantitative, non-verbal, and spatial reasoning. Successful candidates then attend an Assessment Day at Wycombe Abbey, including written tests, interviews, and group activities, providing a comprehensive overview of their academic potential and suitability.
