  • ACHS is the only nationally accredited College offering online certificate, diploma, undergraduate and graduate degree programs in complementary alternative medicine.
  • You can feel confident in choosing ACHS for your holistic medicine education. Our programs and administration have been rigorously evaluated and found to both meet and exceed national accreditation standards.
  • ACHS also is a member of the Higher Education Transfer Alliance (HETA), designed by CHEA. HETA is: "a voluntary group of accredited institutions that are concerned with the importance of student mobility, enhancing success in transfer of credit, and affirming the responsibility and prerogative of individual institutions with respect to acceptance of transfer credits. HETA is a Web-based directory of colleges and universities that is open to all institutions that are accredited by an organization recognized by the Council for Higher Education Accreditation (CHEA) or the United States Department of Education (USDE).
  • "An institution's membership in HETA tells you that its transfer decisions are not made solely on the basis of the accredited status of a sending institution and that the institution has agreed at least to consider transfer requests from other institutions. Each HETA member institution has an interest in cooperative efforts to assure and enhance student mobility."
