How are examination/assessment questions developed?
Questions used for each administration of the Assessment of Fundamental Knowledge (AFK), the Assessment of Clinical Judgement (ACJ), the Written Examination, and the Objective Structured Clinical Examination (OSCE) are developed and reviewed by content experts who are primarily faculty members at Canadian faculties of dentistry.
How are questions selected?
A committee, consisting primarily of general dentists recommended by Provincial Dental Regulatory Authorities, selects the questions for use on assessments or examinations.
What is test equating?
Test equating is a standardized statistical process that is used to ensure each version of an assessment or examination is of equal difficulty. After the answer score sheets have been scanned, NDEB staff and Chief Examiners perform a detailed statistical analysis of the questions. Part of this statistical analysis involves identification and possible elimination of any questions that may not have performed as expected statistically. The questions selected for one version of an assessment or examination may be easier, or more difficult, than another version, so the NDEB uses a test equating process to ensure that all versions are of equivalent difficulty. The result is that the performance required to meet the standardized passing score is the same for each version and that participant and candidate results from different versions are comparable.
