The school was initially located on two sites, the former Heath Grammar School building (initially referred to as the Crossley Heath Annex but later changed to the Crossley Heath 6th Form Centre) and the Crossley and Porter School building. The former Heath building initially housed the combined sixth forms of the two schools, plus the combined fourth form, with all other years being housed at Savile Park. As the number of pupils reduced over the coming years, the 6th form and 4th form were relocated to the Savile Park site and the Free School Lane site was passed over to the local authority to become a training centre. Throughout this period, the staff head count was also reduced to reflect the smaller number of pupils.
