 In 1965 the College Board assumed responsibility and oversight for what would become known as College-Level Examination Program (CLEP®), and soon thereafter sought and received the endorsement of the American Council on Education (ACE). 1967 marked the establishment of 50 test centers throughout the United States and the first national administration of CLEP exams.
