On 2 June 1920 Rendcomb College opened with twelve boys, James Herbert Simpson (formerly a House Master at Rugby School) at the helm as Headmaster and Noel Wills as Chair of Governors.

These estates passed to the Earls of Gloucester by the late 12th century, and were subsequently sub-let to the De La Mare family.

[4] A new wing was added to the main building in 1968 to provide Sixth Form Study bedrooms which subsequently evolved into the Junior part of the School in 2000 for pupils aged 3–11.

[5] In September 1966 the Old Rectory was opened as a boarding house for younger boys, after major alterations and additions and it still serves that purpose today.

The trustees gave the college use of a house in the village ~ number 20 ~ to use for students in their final year, who live together in small groups for a week at a time managing budgets, meals (and laundry!)

In October 2014 Rendcomb College was granted planning permission by Cotswold District Council for a multi-purpose Performing Arts Centre.

[6] At the heart of the School site is the Parish church, St Peter's, which dates back to the 12th century, though much of the current structure reflects a 16th-century rebuilding.

[11] 100 feet above the college, at a point from which a view is obtained, ten acres of the park contain sports pitches and a recently refurbished pavilion.

A heated open-air swimming pool lies next to the college buildings, presented in 1961 by the Dulverton Trust and Major David Wills.

The Griffin Centre opened in 2016 and included a 350-seat auditorium, mirrored dance studio with ballet bars, drama theory classroom, dressing rooms and a prop and set workshop.

Rendcomb College was founded to give students (boys as then was the case) from modest backgrounds a broad-ranging education in an inspirational setting.
