Qualifying scores

Sir Joseph Williamson's Mathematical School

No fixed pass mark. The Medway Test aggregate score (max 700 — English and maths standardised scores double-weighted, plus reasoning) is compared to a threshold set fresh each year: the score level that includes roughly the top 25% of Medway Year 6 children. The threshold is published by Medway Council with results in October. Passing makes a child eligible; each school's oversubscription criteria then apply.
