The NDEB has created a short orientation video for the ACS. This video should be watched by any participant registered to take the assessment. 

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.

ACS Appeal

If you have failed the Assessment of Clinical Skills (ACS), you may submit a written appeal to the NDEB within three months of the release of results. During an ACS Appeal, a panel of three Appeals Committee members will look at the procedures under appeal and determine if the grading criteria was applied correctly.

Assessment of Clinical Skills Appeal Process

Step 1 – Submitting an Appeal

Participants who have failed the Assessment of Clinical Skills (ACS) can make a submission in writing to the Appeals Committee outlining the grounds for requesting to have a grade(s) changed.

The NDEB will accept ACS appeal submissions as of February 12, 2019. 

  • Submissions can include photographs to illustrate the reason for a grade change, but the Appeals Panel will only assess the actual work performed during the assessment.
  • The cost of the ACS appeal is determined annually by the Board. The appeal fee must be paid through your online profile before you submit an appeal.
  • When the NDEB has received your appeal submission, you will receive notification of receipt by email. The email will include the date when your appeal will be heard.
  • You have seven (7) days from the date of your original submission to provide additions or changes to your submission. If your additions or changes are received more than seven (7) days after the original submission, your appeal may be deferred to the next meeting of the Appeals Committee. Additions or changes received after the Appeals Committee has reviewed the appeal will not be considered.

Step 2 – Review by the Appeals Committee

Before the Appeals Committee meets, the Committee will be provided with your appeal record which may consist of the following documents:

  • Your appeal submission.
  • Report of Results for the grades under consideration.
  • Typodonts with all Assessment teeth in position.
  • Identification Card.
  • Participant Communication forms.
  • Invigilator Notes Form for Participant.
  • Time Delay forms.
  • Any photographs taken during the evaluation of your typodonts. Note, there is no requirement to take photographs during the evaluation.

If you have appealed a change of grade for

  • Infection Control, the Infection Control Grading Form will be included.
  • Record of Procedure, the Record of Procedure Grading Checklist will be included.
  • Dental dam, the Dental Dam Requirement Grading Form will be included.

Appeal submissions are reviewed anonymously. Personal information such as name, gender, or country of origin will be removed.

A three-member Panel of the Appeals Committee will review the appeal record, verify if the work submitted was graded in accordance with the grading criteria for the assessment, and determine if any of the grades under consideration should be changed to a higher grade.

The Panel may use resources when considering your appeal, including but not limited to NDEB correspondence, notifications, protocols, policies, typodont viewing forms, etc.

The Appeals Committee will not take health issues or unanticipated extenuating circumstances beyond your control, such as medical or equipment issues, into consideration when reviewing your appeal submission. These are considered compassionate appeals and should be submitted according to the By-laws regarding compassionate appeals.

Step 3 – Results of the Appeal

The Panel will provide a Report of the Appeals Panel to NDEB staff. The report will then be circulated to you by email. Any grade changes will be updated and accessible in the “Results” section of your online profile.
