Selection route
- Medway Test
Local authority selection test · GL Assessment · Three multiple-choice papers with a minimum 20-minute break between papers. Medway maintained primary/junior pupils sit at their own school; pupils from non-Medway primary/junior schools sit at an allocated Medway Council test centre in Medway. Medway independent-school candidates follow their school-specific allocated arrangements.
English and maths age-standardised scores count twice and reasoning once. For September 2027 entry, the minimum weighted total for a grammar assessment is 478, equivalent to 26% of the Medway maintained-school cohort. A grammar assessment does not guarantee a school place.
