How to Become a Licensed Registered Dental Hygienist (RDH) in California by successful completion of the Western Regional Examination Board (WREB)

A law effective January 1, 2010, will allow those seeking licensure in California as a Registered Dental Hygienist (RDH) to obtain licensure by passing the Western Regional Examination Board (WREB). The application and examination forms on this page contain all of the requirements that a WREB applicant for RDH examination and licensure must complete. Applicants must:

1. Be a graduate of a board approved and accredited Dental Hygiene program.
2. Successfully complete the WREB.
3. Complete approved courses in the administration of local anesthesia, soft tissue curretage, and nitrous oxide.
4. Pass the National written examination.

Once the application is deemed complete, a letter will be sent to the applicant containing information allowing the applicant to schedule their law and ethics written examination through a computer-based testing agency (PSI). Qualified applicants must then pass the written Law and Ethics examination.
