ARC celebrated 15 years of dedication to providing an unbiased standardized test for aromatherapists by registering and recertifying 105 Aromatherapists in 2015.

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 2015 ARC proudly registered and recertified 105 Aromatherapists.

“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 2015, ARC hit a benchmark with a cumulative total of over 1,000 candidates  who have sat for the exam since December 2000. This year, 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 2017 is open, and the deadlines are as follows:
