St JohnâÂÂs Beaumont School is a private coâÂÂeducational day and boarding preparatory school for boys and girls aged 3 to 13, located on Priest's Hill, near Old Windsor on the Berkshire - Surrey border in England. Founded in 1888 by the Jesuits as the preparatory school for Beaumont College, it is widely regarded as the oldest purposeâÂÂbuilt preparatory school in the United Kingdom.
In 2025, the school was acquired by Intellego Education. St John's Beaumont School is part of the group's family of schools composed of Core International (Rome), Brighton College Madrid, Brighton College Rome and Brighton College Lisbon.
St John's Beaumont was established in 1888 as a purpose-built preparatory school.
In 2009, Her Majesty Queen Elizabeth II opened the school's new purpose-built sport centre.
In 2023, the school transitioned to a fully co-educational model, welcoming girls into its PreâÂÂPrep and middle school years under the leadership of Headmaster Philip Barr.
In 2025, operational responsibility for St John's Beaumont was transferred from the Jesuits to Intellego Education.
The school campus occupies approximately 50 acres of woodland and playing fields on the edge of Windsor Great Park.
Facilities include specialist classrooms, a 25âÂÂmetre indoor swimming pool, floodlit allâÂÂweather courts, an indoor sports hall with an 8âÂÂmetre climbing wall, dedicated art and music studios, science laboratories, library and ICT suites, and theatre space. Recent developments support the expansion of the pupil body and the transition to coâÂÂeducation, including enhanced spaces for performing arts and sports.
