The NCA is organized into two distinct Commissions. The Higher Learning Commission (HLC) oversees the accreditation of degree-granting colleges and universities. The Commission on Accreditation and School Improvement (CASI) accredits a wide variety of educational institutions, ranging from early childhood, elementary, middle, and secondary schools to adult-vocational, college preparatory, and non-degree granting post-secondary institutions. In July 2006, NCA CASI merged with the Southern Association of Colleges and School Council on Accreditation and School Improvement to form AdvancED.
NCA's monthly newsletter Exchanges, available online, contains information on accreditation sanctions, changes in policy, and board members.
