Welcome to the Committee on Dental Auxiliaries

Registered Dental Hygienist Recorders

COMDA administers all of the dental auxiliary licensure examinations for the Dental Board of California. Each examination uses actual practitioners to conduct the actual grading of the examination.

RDH Examination - The RDH clinical examination is normally given in the Summer and the Fall. Persons who are referred to as "Recorders" are employed by COMDA to assist appointed Examiners during the examination process.

Once a person has successfully served as a Recorder for two or more years, they may be considered for possible appointment as an actual grading Examiner.

Interested persons can expect to be asked to record examiners findings at each examination in their area, which is normally one weekend in June, one weekend in July, and one weekend in October or November. Recorders are paid a $135 per day salary, and are paid per diem and travel expenses within certain State guidelines.

Interested persons must be current practitioners with one or more years of experience, and must complete and submit an Application in order to be considered.
