Choosing a prep school in St John's Wood

11+ or 13+ leavers

Prep schools split by leaving age. Most London girls' and co-ed preps run to Year 6 and prepare for 11+ entry; many traditional boys' preps run to Year 8 and prepare for 13+ entry to schools such as Eton, Harrow, Winchester and Westminster, often via pre-tests in Year 6. Check which a prep is built for before you apply.

Entry points

The main entry points are 3+ or 4+ (nursery or reception), 7+ (Year 3) and, at some boys' preps, 8+. Entry at 4+ is usually by informal assessment or registration order; 7+ usually involves reading, maths and reasoning tests. Registration often closes well over a year before entry.

What to compare

Look at leavers' destinations over several years, not one; how many pupils win senior-school scholarships; class sizes; how much of the week goes to sport, music and drama; and whether the school supports 11+ or 13+ preparation in the timetable or expects outside tutoring.
