City of London School for Boys Entrance Exams

How entry to City of London School for Boys works

City of London School for Boys 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.

City of London School for Boys 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.

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