Aylesbury High School (AHS) was founded in 1959, in Aylesbury, Buckinghamshire, when the previously co-educational Aylesbury Grammar School (founded 1598) split to become two single-sex grammar schools. The two institutions remain on adjacent sites. The school takes its pupils from a wide area as far from Aylesbury as Oxford and Milton Keynes, as admissions are determined by the eleven-plus. The current headmaster is Alan Rosen. The school is colloquially referred to by locals as "Aylesbury Girls'" and by the students as "the High" or "AHS".
