How do I interpret results for the NAC examination?

There have been two important changes to the NAC Examination.

  1. New reporting scale:
  • The new scale for the NAC Examination is 300 to 500
  • Scores can be compared to the mean (M) and standard deviation (SD) of total scores using results from when the new exam score range was established in March 2019


1 Based on candidates in March 2019

2 Based on candidates in March 2013

  1. New pass score:
  • The new pass score for the NAC Examination is 398

Statement of Results and Supplemental Information Report:

Candidates will continue to receive the same two documents in their accounts: The Statement of Results and the Supplemental Information Report.

Statement of Results:

  • Provides the candidate with their final result, their total score and the pass score
  • The body of the report also provides the M and SD of when the scale was established

Supplemental Information Report

  • Formerly known as the Supplemental Feedback Report
  • Provides the candidate with subscores in graphical format for the three domains assessed by the exam: Assessment and Diagnosis, Management and Communication Skills
  • Allows candidates to assess their relative strengths and weakness and compare their subscores with the mean subscores of first-time test takers who passed the exam

How to interpret the results provided in these documents:


  • Small differences in subscores or an overlap between Standard Error of Measurement indicate that the performance in those domains was somewhat similar
  • Overlap between the Standard Error of Measurement for a subscore and the mean score of first-time test takers who passed the exam, signifies that the candidate’s performance is similar to the mean score
  • No overlap suggests that the candidate performed significantly better or significantly worse than first-time test takers who passed
