Distinctive Subject Examinations Designed to Assess Core Osteopathic Medical Knowledge

Comprehensive Osteopathic Medical Achievement Test (COMAT) is a series of osteopathically distinctive subject examinations designed to assess osteopathic medical students’ core knowledge and elements of osteopathic principles and practice essential for pre-doctoral training. Developed by the NBOME and its National Faculty (clerkship directors and clinical rotation directors) in conjunction with faculty at colleges of osteopathic medicine (COMs), COMAT examinations are administered at critical junctures in osteopathic medical training by COMs across the United States and abroad. COMAT exams provide nationally standardized examination modules to evaluate osteopathic medical students’ clinical subject mastery and knowledge across varied clinical education and rotation sites. The exams focus on comprehension and cognitive skills in each discipline with emphasis on clinical problem solving. There are eight clinical discipline COMAT examinations:   Each subject exam reflects the latest advancements in the respective discipline and a consensus of “best-practice” guidelines. COMAT examinations also meet several additional curricular objectives:


Each of the COMAT exams consists of 125 items that must be completed within 2 hours and 30 minutes. A 5-minute tutorial is provided before each exam begins. Every examination in the COMAT series has multiple forms, and all are psychometrically equivalent in content covered, level of difficulty, and reliability, allowing COMs to administer a given COMAT subject exam up to 10 times per year.


The COMAT exam series has many distinctive attributes: Each COM has a secure NBOME account used to track student progress across all NBOME assessments. For in-depth exam information, please review the navigational links on this page, as well as the COMAT Test Administration Guide.
