Westminster School

How Westminster School uses the Common Pre-Tests

According to the school’s admissions pages, Westminster School uses the ISEB Common Pre-Tests as part of its admissions process for entry at 11+ and 13+. The sitting is typically an early stage: schools that use the Pre-Tests generally follow them with their own assessments, interviews or references before making offers.

Key details

Sitting the Pre-Tests: the practical steps

How the process works for any school that uses the Common Pre-Tests — the school-specific parts (deadlines, second-stage assessments) always come from the school itself.

• Register via ISEB’s Guardian Portal

  Registration is free for parents. You register once on ISEB’s Guardian Portal and receive an Applicant ID to give to every senior school you apply to, including Westminster School.

• One shared sitting per academic year

  Your child sits the four online adaptive tests — English, Maths, Verbal and Non-Verbal Reasoning — once in the academic year, and every ISEB school on your list accesses the same result. Results go to the schools; parents are reported not to receive the scores themselves.

• Deadlines are set by the school, not ISEB

  For 2026-27, ISEB’s live testing window runs from 1 September 2026 to late May 2027, but each senior school decides when the sitting must be completed. For 13+ boarding entry, deadlines are reported to fall around October–November of Year 6 at many schools — check the school’s own dates early.

• Where the tests are sat

  The tests are invigilated at approved venues — the child’s own junior or prep school, a senior school being applied to, or an approved invigilation centre in the UK or overseas.
