Professional Exams and Registration

Prior to enrollment with ACHS, students are solely responsible for confirming that the certificate, diploma or degree program in which they enroll will meet their personal and career objectives in the state they reside in. If you are interested in pursuing a career in the health and wellness industry, you should consult with the appropriate state board in your state to assure that your credentials will allow you to achieve your professional goals.

Aromatherapy Membership and Registration Options

An aromatherapy certificate, diploma or degree provides graduates with useful skills that may enhance a current career path or offer opportunity to work in the holistic health and wellness community, however, graduation from an aromatherapy program does not convey any sort of license to practice.

Currently, there are no licensing requirements for aromatherapists in the United States. 

There are memberships and registration options in the industry, including:


Important: Aromatherapists may not claim to treat, diagnose, or cure any illness, because doing so may be considered practicing medicine without a license and a violation of State Medical Practice Acts.
