  • 100 hours of pre-clinical instruction
  • 6 weeks, minimum of 120 hours of clinical training in the sponsoring dental office

Prerequisite: Successful completion of Preliminary Oral Inspection (POI), and Infection Control Practice (ICP) courses.

       * These courses are not required for graduates of a CODA accredited school of dental assisting.
