What is the NDHCE?


The National Dental Hygiene Certification Examination (NDHCE) is designed to assist the provincial and territorial dental hygiene regulatory authorities to determine whether or not an applicant for certification, registration, or licensure possesses adequate knowledge and/or skill related to entry-level dental hygiene practice standards.


The NDHCE is intended to fulfill the written examination requirement. However, acceptance of the NDHCB Certificate is completely at the discretion of the individual provincial or territorial dental hygiene regulatory authority.

The format of the NDHCE is as follows:


  • The exam is delivered in electronic form in computerized testing centres across Canada and is comprised of 200 multiple choice questions;

  • This four-hour exam consists of 2 two-hour sessions delivered back to back but with a compulsory 15 min break in between;

  • the passing score is calculated using a proven psychometric method. The scaled score range is from 200 to 800 with a passing score of 550. Candidates whose total score is at or above 550 pass the exam. Candidates whose total score is below 550 do not pass the exam;

  • the International tooth numbering system is used in the exam;

  • the Metric system is used throughout the exam; and

  • the examination is offered three times a year (in January, May, and September) in at least one centre in each region in Canada (see list).


The NDHCE tests the candidates' ability to apply their knowledge as entry-to-practice professionals to solve oral health care problems and answer questions related to dental hygiene practice. The examination is based on dental hygiene competencies (e.g. Dental Hygiene Process (DHP): Assessment & Diagnosis, DHP: Planning, DHP: Implementation, DHP: Evaluation) outlined in the latest Examination Blueprint. The dental hygiene competencies were reviewed and validated by dental hygiene professionals representing all fields of practice and all regions of Canada. Regulatory authorities were consulted to ensure that the competencies reflect dental hygiene practice in all jurisdictions.
