Boarding or day: You decide by February of the entry year, and Westminster offers a boarding taster in June of Year 7 (age 11 to 12).
The ISEB Pre-Tests: You register your child with ISEB, the Independent Schools Examinations Board, for free, and share the applicant ID with each school and the test center. Westminster’s own registration is separate.
Moving from abroad: Your child can take the Pre-Tests at their current school abroad, but the papers and interviews take place at Westminster.
After the offer: Westminster’s offer is unconditional, though it still expects steady progress, good conduct, and a fully supportive reference from your child’s school in March of Year 8, and waiting-list places can come up until the end of June of Year 8.
Missed registration? The Challenge, Westminster’s King’s Scholarship exam, is open to children under 14 on 1 September of the entry year, registered or not, though an unregistered candidate who doesn’t win a scholarship has no right to an ordinary place. Occasional places may also come up at the Head Master’s discretion, usually after a family relocates.
