The STT is produced by GL Assessment and consists of two multiple-choice papers, each about 60 minutes including a short break between them: 1. Verbal skills — comprehension, technical English, and verbal reasoning. 2. Mathematical and non-verbal skills — maths and non-verbal/spatial reasoning. A shorter practice test is normally given about two days before the main test so children know what to expect and become familiar with the question style. Children at state-funded Buckinghamshire primary/partner schools sit the test at school during the school day.

Children living outside Buckinghamshire CAN sit the Buckinghamshire Secondary Transfer Test (STT). Buckinghamshire is one of the most popular out-of-county grammar destinations — families from Hertfordshire, Oxfordshire, Middlesex and London regularly apply. Registration: out-of-county children register directly with Buckinghamshire County Council (not through their home LA). The registration form and deadline are the same as for Bucks residents — typically June/July for a September test. See buckinghamshire.gov.uk for the current year's registration form. Applying for a place: after results (October), apply via your home LA's Common Application Form by 31 October, listing the Buckinghamshire grammar school(s) you want. Your home LA passes preferences to Bucks. Criteria impact: the pass mark is the same for all children (≥121). Once a child qualifies, many Bucks grammar schools prioritise by catchment area — children living outside the defined priority area compete for remaining places after catchment and sibling applicants. Check the individual school's oversubscription criteria for the exact priority order.
