Because USMLEs’ content pools are large, the transition from DSM-IV to DSM-5 criteria and terminology will need to be gradual and will likely take place over several years. The following principles will guide this transition:
- The highest priority has been given to test content assessing diagnoses that do not appear in DSM-5. This content has already been removed from USMLE examinations.
- USMLE will begin to transition content to include both DSM-IV and DSM-5 terminology. This process will begin in 2014. Start and end dates for this transition will vary by exam.
