In 1938 the school moved to its present site in Farnham Royal in Buckinghamshire, and became a charitable trust in 1968 under the Headmaster at the time Peter Wright.

Caldicott has suggested that these changes maintain the tradition of the school, while making it more inclusive for parents and an easier transition for boys.

[13] The headmaster Peter Wright was active in this, as well as a number of other teachers, targeting boys good at sports and, to a lesser extent, in the choir.

[15] On 4 December 2011, Peter Wright and Hugh Henry, another teacher, were charged with child sex offences alleged to have taken place between 1959 and 1970.

[21] Thames Valley Police on 1 May 2012 charged another former teacher, John Addrison,[22] with sexual offences committed against children at the school between 1979 and 1981.

Addrison was subsequently further charged[23] with child sex offences committed at Moor Park School near Ludlow, Shropshire, between 1985 and 1988.

[24][25] Under ex-headmaster Simon Doggart, another incident of alleged child sexual abuse was reported; the headmaster and the chairman of the board of governors, Lord Justice Scott Baker, suspended the teacher (who did not return).
