Dental Expanded Function Dental Auxiliary - Certificate


This 18-credit part-time certificate program is designed to prepare certified Dental Assistants and licensed Dental Hygienists to become licensed in Washington State as an Expanded Function Dental Auxiliary (EFDA).

Course content is designed to prepare students for the Washington Restorative Exam (WARE) and the restorative portion of the Western Regional Examining Board (WREB).

The program combines didactic, laboratory, and clinical instruction to prepare EFDA's for such duties as placing and contouring restorations, final impressions, and performing certain dental assisting procedures under general supervision.

Note: BTC has not made a determination that the Dental Program curriculum meets educational requirements for licensure/certification outside of Washington State. We encourage students who plan to work out-of-state to check relevant local licensure/certification requirements.

  • Employment and Wage Data Sources

    1Employment data come from the Washington State Board for Community and Technical Colleges (SBCTC) and reflect WA/OR employment for students enrolled at BTC between 2016-17 and 2018-19. Students are included in the employment rate if they left with a credential. Rates are not shown for programs with fewer than 10 students meeting the above criteria.

    2Wage data come from Washington State Employment Security Department (ESD) 2020 Occupational Employment and Wage Estimates (Washington State wage) and reflect 2015-2018 employment. Wage data represent occupations that BTC faculty have identified as the most relevant career paths for program graduates. Note that these wages reflect employees with varying educational levels/credentials. For cases in which multiple occupations have been identified by faculty, a weighted percentile is calculated using each occupation’s percentile wage and employment size estimate. Wages are not shown for programs for which occupations do not meet the ESD’s minimum thresholds for publishing. If the program has wage data from the Washington SBCTC that involves shift work, these ESD wages reflect the same number of hours used in the annual wage calculation. Starting wage = 25th percentile, median wage = 50th percentile, wage potential = 75th percentile.
