Scoring NBCE Written Exams


Now that the written exams are complete, please see the following explanation of how they are scored.

The passing score for each NBCE exam is individually determined based on multiple inputs including a committee which consists of a combination of subject-matter experts (chiropractic college professors) and chiropractors representing state licensing boards.  The committee carefully considers each question on an exam and provides an assessment.  The individual marks for each question are combined to produce a recommended passing score for the entire exam.

Passing scores are periodically reviewed and they are reexamined when there is a significant change in a test plan.

The passing score is converted to a scaled score of 375.  The remainder of the exam is scaled above and below 375.

Once a passing score is implemented, it is maintained in subsequent exams through a process called equating.  Equating is a procedural and mathematical process that maintains the comparability of scaled scores on an exam from one administration to the next.

The average score on Part I, Part II, and the Physiotherapy exams is 500.  The standard deviations are 100.  Approximately 68% of the scores range from 400 to 600; about 95% of the scores range from 300 to 700.

  1. How many questions of the 90 are needed to recieve a score or 375?

    • Unlike the routine tests that you may take in the classroom, the Part I exams are mathematically equated to ensure that all examinees have the same opportunity to perform well, regardless of which form of the examination they take, or when they take it. This provides consistency from year to year and across all administrations. Because of this, there might be a slight variation of the passing score with each administration to maintain equality.
