The Accrediting Council for Continuing Education and Training has been aiming to inspire and promote quality-oriented continuing education and training since 1978. ACCET is officially recognized as an accrediting body by the U.S. Department of Education and the International Organization for Standardization. The accrediting council focuses on institutions that offer non-collegiate continuing education and training programs. Their service sets them apart from most accrediting bodies because it is not exclusively dedicated college institutions.

The institutions accredited by the ACCET are organizations, rather than colleges, that provide educational resources and training within corporations or companies. These continuing education and training programs are spread throughout the United States as private career schools, corporate training departments, intensive English teaching programs, trade associations, labor union training programs, religious organizations, public affairs societies, and volunteer organizations. ACCET is a voluntary affiliation of organizations committed to regulating continuing education programs through peer review and evaluation processes.
