The Aromatherapy Registration Council (ARC) has developed and administers the Registered AromatherapistTM (RA) registration program as a means to fulfill its mission of promoting the safe delivery and effective practice of aromatherapy, with the ultimate purpose of protecting public health and safety. Candidates who successfully pass the exam earn the RA credential and receive a Certificate of Registration.

In 2018 ARC proudly registered 118 RA’s and recertified 3 RA’s.

“ARC is thrilled to see a new group of aromatherapists gain their RA registration and would like to congratulate them on this achievement.” said Dorene Petersen, ARC Chair.

In 2018, ARC hit a benchmark with a cumulative total of over 1,484 candidates who have sat for the exam since December 2000. In 2018, ARC candidates took the exam in three languages: English, Japanese and Korean.

The ARC Board encourages all aromatherapists who are dedicated to demonstrating a commitment to professionalism and public safety to consider earning their RA credential. Further, maintaining and renewing the RA registration shows a continued commitment to ongoing education, professionalism and public safety.

The ARC exam is composed of multiple-choice questions submitted by aromatherapy subject matter experts, aromatherapy educators, RA’s, and industry members. It is offered during two examination windows each year through the Professional Testing Corporation (PTC). Registration for 2019 is open, and the deadlines for the October exam is:
