Ash’s view

A grand boarding school with a strong sense of community and excellent pastoral care. ISEB pre-test at 13+, then school papers and interview. At 11+ they run their own assessment day. They value all-rounders — sport, music and drama matter alongside academics.

How entry to Haileybury works

Haileybury uses the ISEB Common Pre-Test as part of its admissions. It is an online, adaptive test in four parts: English (40 minutes), maths (40 minutes), non-verbal reasoning (30 minutes) and verbal reasoning (25 minutes). A child sits it once, and the scores are shared with each school that asks for them.

Because the test adapts to each answer, confident accuracy matters more than speed alone, and verbal reasoning is often the section that separates strong candidates.

Haileybury also sets its own assessments. Depending on the entry point, these can include written papers, reasoning tests, an interview or a group activity, and they are where the school looks most closely at how a child thinks.

For 13+ entry (joining in Year 9), many schools assess children in Year 6 or Year 7, well before they start, so the timetable is worth checking early.

At 16+ (Sixth Form entry), students are usually assessed in the autumn of Year 11 with a mix of reasoning tests, subject papers and interviews, and offers are normally conditional on GCSE results. There is more on this on my 16+ entry page.

Dates and requirements change from year to year, so always check the latest details on the school’s website.
