St Simon Stock is a mixed Roman Catholic comprehensive co-educational school with an academic and pastoral tradition.

Its function is to serve the educational needs of Roman Catholic students in the Mid Kent area.

The headteacher at the time, Mr McParland, stated that this was to emphasise the school's Catholic ethos.

[1] In the early 2000s, after the appointment of John McParland as headteacher, a drama studio was built in memory of Kath Topping, a former school governor, along with two new science classrooms.

One other new block has been built, which contains three specialist ICT rooms, which are equipped with a full class set of 30 desktop computers, and interactive whiteboards.
