COMAT Scoring and Reporting
About COMAT Scoring & Reporting
Scores for COMAT examinations are reported as standard scores, which account for minor differences in difficulty between forms.
COMAT
FBS-C Exams
The NBOME reports scaled (or standard) scores that are based on a reference group of students taking the FBS-C examination for the first time in their second year of osteopathic medical school during 2021-2023. The scale of the FBS-C exam ranges from 109 to 300, with the reference group calibrated to a mean of 200 and a standard deviation of 10. A scaled score above 200 indicates an above average performance with respect to the reference group.
COMAT
FBS-T Exams
The NBOME reports scaled (or standard) scores that are derived from a normative reference group of students taking the FBS-T exam for the first time in their first or second year of osteopathic medical school during 2022-2024. The score scale ranges from 300 to 800, with the reference group calibrated to a mean of 550 and a standard deviation of 65. A scaled score above 550 indicates an above average performance with respect to the reference group.
COMAT Clinical Exams
The NBOME reports scaled (or standard) scores that are derived from a normative reference group of first-time test takers from osteopathic medical schools who took the assessment during 2023-2025, generally at the conclusion of a clerkship, clinical rotation, or course. The score scale ranges from 9 to 200, with the reference group calibrated to a mean of 100 and a standard deviation of 10. A scaled score above 100 indicates an above average performance with respect to the reference group.
The COMAT Clinical Percentile Score Conversion Table converts standard scores into percentile scores.

Score Reports
Score reports are scheduled to be released 5-10 business days after administration.
- Both single administration and cumulative reports are provided to COMs.
- Both reports provide a score roster, a frequency table, and a school-level performance summary with a graphic profile of school performance on subtopics.
- Cumulative reports include the features above and summarize school performance for examinations taken within a selected range of dates.
- Key Phrase reports are available as downloadable files on the Cumulative reports page in the NBOME Portal.
COM Comparative Summary Reports by COMAT discipline are available to COMs on the secure Dean’s Page of the NBOME Portal. COMs can compare their COM student performance with other unidentified COMs as well as review, print, and archive reports. These reports for the previous testing cycle are uploaded annually in August or September.
The NBOME will not send COMAT student score reports directly to students.

Score Confirmation
The NBOME conducts a thorough quality assurance process to ensure that all candidate scores are accurate. However, if a COM chooses, we will confirm an examination score for any COMAT exam if a school coordinator submits a written request within 30 days after the scores are released. Students may not request score confirmations. These requests are directed back to the school coordinator.
Because score confirmation is limited solely to computer-recorded responses, the score is unlikely to change. The NBOME will ensure that all sections were complete and that responses were graded against the proper form. The NBOME does not release information about the scoring of individual exam questions.
The fee for score confirmation is $25, and upon making the request, the COM must include a check or credit card information. A score confirmation entails retrieving the original test responses, checking for any testing or data abnormalities, rescoring using a process different from the operational scoring process, and comparing the rescored results with the originally reported scores. Results of a score confirmation will be sent to the school coordinator by Client Services within two weeks of the request.
