COMAT FBS Comprehensive

This summative and formative assessment is designed to assess first and second year osteopathic medical student knowledge, skills and abilities in the foundational biomedical sciences as they prepare for COMLEX-USA Level 1. It may also be used by other health professional schools for formative purposes.

Format

The exam is given in two separate timed sections of 100 items each - 2 hours per section. There is an optional break halfway through the exam, the length of which is up to each COM’s discretion. Unused test time from section 1 will not be added to section 2. The FBS Comprehensive exam is offered in multiple forms, and all are psychometrically equivalent in content covered, level of difficulty, and reliability, allowing COMs to administer the FBS exams multiple times per year.

Exam Blueprint

Content Outline and Assessment Objectives

The FBS Comprehensive examination may be used for end-of-course assessment for students enrolled at a college of osteopathic medicine (COM). Individual COMs may also administer the examination at other times in accordance with their curriculum goals and mission. This examination emphasizes core knowledge and elements of osteopathic principles and practice in the foundational biomedical sciences disciplines that are essential for the pre-doctoral osteopathic medical student.

The exam blueprint below contains the FBS topics covered in two dimensions: Dimension 1 – Body Systems and Dimension 2 – Disciplines.
