WHAT IS ACCREDITATION
Accreditation for Naturopathic programs in the United States is an entirely "voluntary" process. Accreditation for an institution of learning represents a "validation" that the school programs have been thoroughly investigated and found worthy of recognition. This investigation is conducted by a qualified group of people familiar with the programs offered. Students and institutions of learning have come to rely on decisions from ANMAB as a reliable source for determining quality in education.
