COMLEX-USA Scoring Principles Intro Paragraph
For the COMLEX-USA computer-based cognitive examinations, the number of items answered correctly (the raw score) is converted to a standard score for the purposes of reporting results and providing a pass-fail designation. The mean of the standard score for all three COMLEX-USA computer-based cognitive examinations has historically been in the 500-550 range.
With the exception of pretest questions, which do not contribute to the scores candidates receive, each test question contributes equally to the candidate’s score. The total reported score is a model-based standard score that takes into account the response to each question and the psychometric properties of the examination.
A passing score for all COMLEX-USA Levels is based solely on a candidate’s performance on the total examination, not on a candidate’s performance in individual content areas. Score reports display a graphical representation of performance profiles that summarizes strengths and weaknesses in relation to the examination blueprint.
COMLEX-USA computer-based examinations are administered continuously throughout the year. Osteopathic medical schools receive summary reports at the end of the annual testing cycle. COMLEX-USA school summary reports provide school-level in comparison to the national average performance.
COMLEX-USA Level 1, Level 2-CE and Level 3 examinations replaced the Part I, II and III examinations in 1998, 1997, 1995 respectively.
The scores reported for Parts I, II and III after 1988 are 3-digit standard scores for the whole examinations. Scores reported for Parts I and II before 1987 are the minimum standard scores (2-digit) among all the component scores of the examinations. Score reported for Part III are standard scores (2-digit) for the whole examination.
