Comprehensive Basic Science Subject Examination Content Changes To Become Effective Feb. 3, 2021

Posted December 14, 2020

Updated June 2, 2022

All Comprehensive Basic Science subject examination forms have increased the number of items assessing communication skills. This change aligns with an increase in the number of items that assess knowledge of Communication and Interpersonal Skills on Step 1.  

While content will be realigned, the number of test questions in the examination will remain unchanged. The length of the exam and score feedback turnaround time will also remain unchanged. An updated content outline is available for your reference.

Additional information regarding content changes to the Comprehensive Clinical Science subject examination will be provided in January 2021.
