SACREs and ASCs
Although RE is part of the basic school curriculum, it is not part of the English National Curriculum. Instead its content and management are determined locally. Standing Advisory Councils for Religious Education (SACREs) are the local committees that advise local authorities responsible for education on matters connected with RE and religious worship. ASCs (Agreed Syllabus Conferences) are the local committees that draw up local RE syllabuses. They are required to review the local RE syllabus at least every five years. Although ASCs are constituted separately to the local SACRE, they often comprise many of the same people and have the same committee structure.
