Clayesmore School in detail

Clayesmore School in its own words

From the headteacher's welcome: "There is a quality that is easier to feel than it is to describe that strikes a family on their first visit to Clayesmore. The campus is impressive, the facilities are excellent, but it is the atmosphere that stays with you: ambitious, warm, and genuinely alive."

Coming up: an open day on Friday 27 November 2026 at 3.30pm. Check the school's website before you go, as dates can change.
