Medway
Sir Joseph Williamson's Mathematical School
Exceptional results, but a place depends on the entrance test rather than where you live — worth a look only if you are planning to sit it.
What the data says
Published data, read plainly. It tells you what to check next; it does not guarantee a place or replace your local authority’s admissions guidance.
Attainment 8 of 69.5 is well above the national average of around 46. This reflects strong GCSE outcomes across the standard subject basket.

Admissions realism depends on your home postcode and the school's published allocation data. Enter your postcode on this page to get a more specific assessment, and always verify the latest policy on the school's official admissions page.
This is a selective school. Admission usually requires passing an entrance test. Check the school's admissions policy for test registration deadlines.

- The DfE stopped publishing Oxbridge and Russell Group shares for individual schools after the 2022-23 performance tables (students who left in 2019/20). Top-third figures continue.
- Figures are percentages of all students who finished 16 to 18 study at the school, counting those who sustained a university place in the two years after leaving.
- Rankings use the average across years weighted by the number of students; a school needs at least 2 years and 50 students to be ranked. The top-third ranking uses the latest 3 years. Ranks are among state-funded schools and colleges.
- '<0.5%' means above zero but under half a percent. 'Suppressed' means 5 or fewer students.
