 By 1969, Mr David Pennells had been appointed as the new headmaster, and despite some opposition, the school became comprehensive in 1972, changing its name to Cheadle Hulme County High School, and in 1974 with government changes from Cheshire County Council to Stockport Council, Cheadle Hulme High School.There was a significant building programme, including an associated sports centre, so the school could now accommodate up to 1,500 children.The change to a comprehensive system resulted in the loss of the house system, and replaced with year groups and form tutors.
