If you want to become a licensed dental hygienist in Washington D.C., you must be prepared to complete the following:
Step 1. Complete an Educational Program in the Practice of Dental Hygiene
To achieve a dental hygienist license in Washington D.C., you must successfully complete an educational program in the practice of dental hygiene that is at least 2 academic years in length and is accredited by the Commission on Dental Accreditation (CODA) of the American Dental Association (ADA).
Although there is but one CODA-accredited dental hygiene program in Washington D.C., there are 7 programs in Maryland and 6 programs in Virginia.
A two-year CODA-accredited dental hygiene program culminates in an associate degree (A.A., A.S., or A.A.S.), while a four-year CODA-accredited program culminates in a bachelor degree (B.S.) in dental hygiene. Both programs are recognized by the American Dental Hygienists Association as entry-level programs, although the minimum degree requirement for licensure is an associate degree.
Dental hygienists who want to pursue additional opportunities in the field of dental hygiene often complete bachelor degrees in dental hygiene, as it may allow them to manage dental offices or work in research or educational settings. Further, master’s degrees in this profession are generally reserved for individuals who want to pursue careers in teaching, research, or in clinical practice outside of the dental office.
Step 2. Receive a Passing Score on the National Board of Dental Hygiene Examination
The National Board Dental Hygiene Examination (NBDHE) through the Joint Commission on National Dental Examinations (JCNDE) has become a standard assessment tool for the licensure of dental hygienists throughout the U.S., including the District of Columbia.
The NBDHE, which consists of 350 questions that are designed to assess a candidate’s basic dental hygiene knowledge, including biomedical, dental hygiene, and dental sciences, is administered at Pearson VUE testing centers throughout the United States. In Washington D.C., you may take the NBDHE at the Pearson VUE testing center on 1615 L Street NW or in nearby Bethesda, Maryland, or Alexandria or Vienna, Virginia.
Before you can schedule to take the NBDHE through Pearson VUE, you must apply through the JCNDE. Once your eligibility to sit for the exam has been verified by the JCNDE, you can expect an email from the JCNDE detailing examination scheduling appointment instructions.
Step 3. Receive a Passing Score on the Commission on Dental Competency Assessments (CDCA) Examination
Once you have successfully passed the NBDHE, you may then apply to take the Commission on Dental Competency Assessments (CDCA) practical examination. You can contact CDCA and schedule your examination at the same time you begin the license application process. CDCA schedules candidates, administers all examinations, scores the examinations, and notifies candidates of their test results. It is up to you, however, to ensure that your examination results are forwarded to the Board.
The CDCA examination is offered at least 5 times a year: September, November, February, April, and July. One of the CDCA examination sites is located at Howard University in Washington D.C. Contact CDCA at 301-563-3300 to begin the application process.
Step 4. Receive a Passing Score on the District of Columbia Dental Law Examination
