Assessment of Clinical Skills (ACS)

Assessment of Clinical Skills (ACS)

The Assessment of Clinical Skills (ACS) assesses clinical competence through the performance of clinical requirements on simulated patients.


The ACS is held over a two-day period during which you perform twelve (12) dental procedures on simulated patients (manikins) in a clinical setting.

ACS locations

The ACS is administered at Faculties of Dentistry in Canada and in New Zealand. Although the clinics use standard dental equipment, each of the dental clinics are different and may use slightly different equipment.

The NDEB is aware that some Faculties of Dentistry offer clinic orientation sessions through their Continuing Education Departments. You must contact the Faculties directly to inquire if they are offering an orientation session. Contact information can be found under the Resources section. The NDEB does not endorse or recommend any program for the purpose of preparing participants for NDEB examinations.

Each ACS location may have different handpiece connections. The handpiece connections document provides images and descriptions of the handpiece connections at Canadian Faculties of Dentistry.

ACS Protocol and Orientation

The ACS Protocol contains important information regarding the ACS. This document should be read carefully prior to the examination. In the event of any inconsistencies between documents the information found in the English ACS Protocol will prevail.

The NDEB has created a short orientation video for the ACS. This video should be watched if you are registered to take the ACS.

Passing Standard

The restorative and endodontic requirements are graded using the four point grading system illustrated in the ACS Protocol.


You can take the ACS a maximum of three times.

Typodont viewings

If you have failed the ACS, you are eligible to view your typodonts in person. Typodont viewings are optional and offer you the chance to review your work in preparation for your appeals submission. You are not required to view your typodonts to submit an ACS appeal.

Typodont viewings for the June 2021 ACS will take place on July 29 and August 12, 2021. The deadline date to schedule an appointment is July 30, 2021.
