A independent school in South London for girls, with entry at 11+. Here is the test it uses, what is in it and how to prepare.
Most independent schools set their own maths and English papers in January of Year 6, often with a reasoning test, creative writing and an interview.
| Stage | Paper | Questions | Time |
|---|---|---|---|
| 11+ assessment | Maths | 25 | 60 minutes |
| 11+ assessment | English | 12 | 60 minutes |
| 11+ assessment | Reasoning | 40 | 40 minutes |
| 11+ assessment | Puzzles & Problem Solving | 15 | 30 minutes |
Paper formats are indicative and change from year to year. Always check the current arrangements with the school or local authority.
The Independent school 11+ (own papers) covers maths, English, verbal reasoning and non-verbal reasoning. Most families start steady preparation in Year 4 or early Year 5, building accuracy first and speed later, then sit timed papers through the summer before the test, which usually takes place in January.
For maths, secure the Key Stage 2 arithmetic, fractions, ratio and problem solving before moving to the multi-step questions that separate the strongest candidates.
For English, read widely every day and practise comprehension, vocabulary, spelling, punctuation and grammar; selective tests reward precise word knowledge.
Verbal reasoning is a set of learnable question types, such as letter codes, hidden words and word analogies. Learning each type, then practising it against the clock, lifts scores quickly.
Non-verbal reasoning is about spotting patterns in shapes: rotations, reflections, sequences and matrices. Short, regular sessions work better than long ones.
This test includes a piece of writing, so practise planning and writing a short story or description in a set time.

Schools do not publish pass marks. As a guide, Prism suggests a child aims to score around 88% consistently in practice for a super-selective school. This is Prism’s own estimate, not a figure from the school, and no score guarantees a place.
Most families start in Year 4 or early Year 5, then practise timed papers during the summer before the test, which usually takes place in January.
Prism starts with a free assessment across maths, English, verbal and non-verbal reasoning, then builds a weekly plan for your target schools. Parents follow progress free.
