ACS Locations

Handpiece Connections

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.


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 Reference Material and Resources section. The NDEB does not endorse or recommend any program for the purpose of preparing participants for NDEB examinations or assessments.

Passing Standard

You will receive a grade for each requirement as determined by the evaluation criteria for the requirement and the “Grade Derivation Grid”.  The final result will be determined using the “Final Result” Grade Derivation Grid.

In order to pass the ACS you must obtain:

Eight or more grades of A / A+ and no E grade
Nine or more grades of A / A+ and no more than one E grade

The Grade Derivation Grid can be found in the ACS Protocol.

You can take the ACS a maximum of three times.
