The Assessment of Clinical Judgement (ACJ) assesses your ability to formulate a diagnosis and make clinical decisions, as well as evaluate your knowledge in oral radiology and ability to make a radiographic interpretation and diagnosis.
Assessment of Clinical Judgement (ACJ®)
Format and Content
The ACJ is a 5.5 hour examination with one scheduled break. The ACJ consists of 120-150 single-answer and multi-answer multiple-choice type questions. Each section of the ACJ will contain case-based diagnosis, treatment planning and clinical decision-making questions, and radiographic interpretation questions.
Case-based diagnosis, treatment planning and clinical decision-making questions evaluate your ability to formulate a diagnosis and to make clinical decisions. Case histories, dental charts, radiographic images, and photographs may be provided.
Radiographic interpretation questions evaluate your knowledge in oral radiology and ability to make a radiographic interpretation and diagnosis using radiographic images.
The ACJ is delivered on computers at Prometric and other test centres. The NDEB’s e-Exam Orientation should be viewed prior to taking the ACJ.
The ACJ Question and Answer Framework containing examples of questions is available in the How to prepare section of the website.

Terminology
The NDEB updates examination questions on a regular basis as new knowledge becomes available.
Scoring
A test equated, re-scaled score of 75 or greater is reported as a Pass. A test equated, re-scaled score of less than 75 is reported as a Fail. Candidates who receive a Fail will also receive their test equated, re-scaled score. No further breakdown of results is available.
Passing Standard
In order to ensure the consistency of scores on all the versions of the examination, the NDEB uses a test-equating procedure. This procedure correlates a standardized reference examination with the current version of the examination and determines the standardized mark. The NDEB maintains a standardized passing score of 75 on all examinations.
