NBOME offers the Comprehensive Osteopathic Medical Self-Assessment Examination (COMSAE) for osteopathic students and residents to prepare for the COMLEX-USA cognitive examination. We encourage use of this exam as a gauge of the base of knowledge and ability. COMSAE is not intended to predict performance on any of the COMLEX-USA examinations. However, candidates who have taken a timed COMSAE before taking their first COMLEX-USA cognitive examination at the corresponding level demonstrate greater proficiency, on average, relative to candidates who did not take a timed COMSAE before their first COMLEX-USA examination.

More information on COMSAE can be found here.


The NBOME has developed a new assessment called WelCOM. The WelCOM assessment series is offered on the CATALYST platform. The content is also aligned to COMLEX-USA examinations (currently for Level 1 and Level 2-CE). It provides osteopathic medical students with an alternative means of reinforcing their medical knowledge by assessing their strengths and weaknesses in their knowledge of osteopathic medicine.

More information on WelCOM can be found here.
