Harefield School is a secondary school in Uxbridge, London. Located on the site of the former community school, John Penrose School, which closed on 31 August 2005,[1] it reopened as an academy in 2005 and specialises in sports. Among other connections, Watford Football Club provides coaching there (the school serves as its youth system), and it also hosts an elite gymnastics division. 2024, the school began phasing out its sixth form, and is no longer accepting admissions for that area. In September 2023, the school joined the academy trust QED, and changed its name to Harefield School.
In January 2014, the academy was one of three schools that featured in BBC Three's six-part series Tough Young Teachers. The series was filmed throughout the 2012–2013 academic year.
