Trevelyan School is a comprehensive middle school in Windsor, Berkshire, England, within the Royal Borough of Windsor and Maidenhead LEA. The school is attended by approximately 600 boys and girls aged between nine and thirteen.
The school was officially opened on 26 March 1930 as the New Windsor Council School by Sir Charles Trevelyan, the President of the Board of Education. It was renamed Trevelyan School in his honour in 1954.
Since 1979, it has been a co-educational comprehensive Middle School, catering for pupils between the ages of nine and thirteen.
In 1998, the Royal Borough of Windsor and Maidenhead assumed responsibility for the school from the former Royal County of Berkshire Council.
In 2002 the school moved from its Green Lane home for the previous 72 years to a new site in Wood Close.
In 2007, Trevelyan School became an associate Arts College, linked to The Windsor Boys' School.
Trevelyan School has twenty classes of students, arranged in four year groups of five classes each. Year 5 is the youngest year group in the school, and year 8 the eldest. Each class in a year group belongs to one of the school's five houses, named after people who have played an important part in the school's history:
Before September 2005, there were four houses named after the British patron saints:
Patrick's House won the annual house-points competition for the five years before the names were changed.[citation needed]
