Choosing a prep school

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.

Prep schools: common questions

How many independent prep schools does Houseroom list?
Houseroom lists 485 independent prep schools: 80 girls', 49 boys' and 356 co-ed. Most are in London and the South East.
How much do prep schools cost?
The median top day fee across the prep schools Houseroom lists is £24,300 a year, including 20% VAT since January 2025. Boarding, lunches, uniform and trips cost extra.
What age do children start prep school?
Most prep schools take children from 3 or 4 into a pre-prep or nursery, with a second main entry at 7+ (Year 3). Some boys' preps also admit at 8+.
What is the difference between a prep school and a pre-prep?
A pre-prep teaches children from about 3 to 7. The prep school proper runs from 7 to 11 or 13. Many schools have both on one site, so children move up without a second admissions round.
Do prep schools prepare for the 11+ and 13+?
Yes. Preps that run to Year 6 prepare for 11+ entry to senior schools; preps that run to Year 8 prepare for 13+ entry, including the Common Entrance or a senior school's own assessment and any pre-tests in Year 6.
