Westminster Under School 7 Plus (7+) Exam Guide

About Westminster Under School

Westminster Under School is the junior school of Westminster School, and its 7+ is one of the most sought-after entry points in London. The school is now co-educational at 4+, 7+ and 11+, having admitted its first girls in September 2026 as part of a move to full co-education by 2030.

About 60 boys and girls join at 7+ into Year 3 for 2027 entry, though the school has said this will fall to around 28 by September 2029 as the transition settles. The old 8+ entry point has been discontinued; 4+, 7+ and 11+ are now the only routes in.

Admissions information for 2027 entry to Westminster Under School at 7 Plus (7+)

Note the deadline first: 30 September 2026, weeks earlier than most London 7+ registrations close. Miss it and the cycle is gone.

The process runs in two rounds. Round 1, in mid-October, is written: maths, English, verbal and non-verbal reasoning, sat in small groups with breaks built in. Round 2, in November, invites roughly 100 to 120 children (the school’s own pages give both figures) to a session built to feel like a normal school morning: games on arrival, classroom activities, an outside play break and a snack, plus an informal interview, usually in small groups, and further short tests in English, spelling and maths.

The school is blunt on two points: there is no sibling policy, ‘places are awarded solely on the basis of performance’, and bursaries only exist from 11+. Offers come shortly after round 2, in later November.

How can I register my child for the 7 Plus (7+) assessment at Westminster Under School?

Registration for September 2027 entry opened on 1 September 2025 and closes on 30 September 2026, via the school’s online admissions system, with a £300 non-refundable fee. Children who joined the school’s own Pre-Prep at 4+ come through a separate continuous-assessment route, so the external 7+ field is competing for the places that remain.

What is the 7 Plus (7+) assessment format at Westminster Under School?

Round 1 is the full written spread: maths, English reading and writing, verbal reasoning and non-verbal reasoning. That makes Westminster Under one of the few London 7+ assessments where reasoning practice genuinely earns its place alongside English and maths.

The school’s advice to parents is to avoid outside tuition, ‘which we feel can detract from freshness, spontaneity and eagerness to learn’. Take that seriously in how you prepare: the aim is a child who has met the question types before and isn’t thrown by a timed booklet, not one who has been drilled through the summer.

Westminster Under School 7 Plus (7+) top tips for your child

• Put 30 September 2026 in your calendar now; it is unusually early and non-negotiable
• Cover all four papers lightly rather than two heavily: maths, English, verbal and non-verbal reasoning all appear
• Spelling comes up again in round 2, so keep a gentle spelling habit going
• Round 2 is a mock school morning; children who settle quickly into new groups show best, and that comes from ordinary social practice, not tutoring
• Watch for the information booklet in March for the exact October test date
