About Us

The Williamson Trust was founded by Governors of Sir Joseph Williamson’s Mathematical School in April 2011. The Chair of Governors, Mr Michael Costello, is also Chair of The Williamson Trust and a National Leader of Governance.

“The Trust in charge of the Academy provides effective support.”  -  Ofsted

The Trust is governed by an overarching Academy Trust Board, with significant powers delegated to local governing bodies.

There are currently six academies in our family of schools in Medway, Kent:

  • Sir Joseph Williamson’s Mathematical School
  • The Hundred of Hoo Academy
  • High Halstow Primary School
  • Elaine Primary Academy
  • Allhallows Primary Academy
  • Stoke Community School

We are also, in partnership with the Rochester Diocese Board of Education, co-sponsor of St James’ Church of England Primary Academy School in Grain.

“The Trust is fully committed to raising achievement and has ensured that teachers receive high quality professional development at all levels.”  - Ofsted
