Ipswich High School was opened as a school for girls in the Assembly Rooms in Northgate Street, Ipswich, on 30 April 1878 with 43 pupils. The first headmistress, Miss Sophie Youngman, held the position for 21 years and the school flourished and expanded under her leadership. She was succeeded by Miss Kennett and, in 1905, the Council of the Trust purchased a large private house and grounds in Westerfield Road, Ipswich. The move provided a more modern classroom standard, science laboratories and a playing field. Another house, Woodview House, was purchased in 1913. Owing to the continued expansion of the school and the demands of the modern curriculum, the decision was taken in 1992 to rehouse the school at Woolverstone Hall, a Grade 1 listed building set in of parkland on the banks of the River Orwell, the former premises of Woolverstone Hall School for boys. Transition to the co-educational Diamond School model was commenced in 2018, with induction of the first boys scheduled for the new school year beginning in September. The change from a single-sex to co-educational system received mixed responses from parents and alumnae. the school serves a wide area of Suffolk and north Essex, taking girls and boys aged 4–18 years and providing both primary and secondary school education, including a sixth form, where pupils take traditional A Levels in subjects such as Latin, History and Mathematics.
Governance
Following acquisition of the school by London and Oxford Group in 2017, the principal and the chair of governors remained in their positions, reporting to the ownership subsidiary Ipswich Education Limited.
