Admissions information
The Sir Joseph Williamsons Mathematical School entrance test is the Medway Test, administered by Medway Council. Here is everything you need to know about the Sir Joseph Williamson’s Mathematical School admissions criteria and exam structure.
Sir Joseph Williamson’s Mathematical School belongs to the Medway 11+ Consortium and selects pupils on academic ability through the Medway Test. The Medway Test is made up of three papers covering English, Maths and Reasoning, the latter including verbal, non-verbal and spatial reasoning. The papers are multiple-choice and use a separate answer sheet.
In the Medway Test, the English and Maths papers carry greater weight than the Reasoning paper, and all scores are standardised and adjusted for age. Pupils who achieve a standardised score above the Medway threshold are deemed selective and are eligible to apply, although meeting the threshold does not guarantee a place.
Parents register their child for the Medway Test online through Medway Council, with registration typically opening in mid-May and closing in mid-June. Children who attend a Medway maintained primary or junior school usually sit the test at their own school, while children who do not sit it at a Medway test centre. Parents must also name Sir Joseph Williamson’s Mathematical School on the Secondary Common Application Form (SCAF).
Medway Test results are typically issued to parents in mid-October, after which families submit their secondary school application to the Local Authority, ranking their preferred schools, by the 31st October deadline. School place offers are confirmed on National Offer Day in early March. Being deemed selective does not guarantee a place, as the school is regularly oversubscribed.
Key admissions details
Sir Joseph Williamson’s Mathematical School admits a large boys’ cohort into Year 7 each year.
Sir Joseph Williamson’s Mathematical School does not operate a formal catchment area, so a child deemed selective may apply regardless of where they live. Where the school is oversubscribed, places are allocated after looked-after children, siblings, staff children and health cases to those who live closest, measured by the shortest safe route.
