Alleyn’s School is a leading co-educational independent day school in Dulwich, London, educating pupils aged 4–18 across its Senior School and two Junior Schools: Alleyn’s Oakfield and Alleyn’s Junior School.
A system of prefects was introduced at Alleyn’s by Herbert Baker who was Headmaster for just one year in 1902-3. Prefects wore boaters to distinguish them from the other boys up until the 1950s.
