In 1966 Chippenham Grammar School and the Girls' High School integrated with the Chippenham Secondary Modern Schools in a semi-comprehensive system with all 11 to 13 year old boys and girls being educated on the Hardenhuish site.
Finally, in 1975 a fully comprehensive school came into existence, serving the northern and western areas of Chippenham and adjacent villages, and taking the name Hardenhuish School.
