The purpose of the NDSE is to test entry-level competencies required of specialists. The NDSE covers general specialty knowledge including basic sciences, clinical diagnosis, and treatment planning. The level of knowledge required is consistent with Commission on Dental Accreditation of Canada (CDAC) requirements in each of the specialties.

The Royal College of Dentists of Canada (RCDC) is responsible for developing, administering, and scoring the examinations. To do this, the NDSE Committee who, along with the Specialty Examination Team Leads and staff, oversee all aspects of the examination processes.
