Comprehensive Self-Assessment Services
The NBME offers three web-based self-assessments to medical students and graduates evaluating their readiness to take USMLE:
- Comprehensive Basic Science Self-Assessment (CBSSA)
The CBSSA uses multiple-choice items based on information typically covered during basic science medical education courses. The content of the CBSSA items resembles the content of those in Step 1 of the United States Medical Licensing Examination® (USMLE®).
- Comprehensive Clinical Science Self-Assessment (CCSSA)
The CCSSA uses multiple-choice items based on information typically covered during the core clinical clerkships. The content of the CCSSA items resembles the content of those in Step 2 CK of the USMLE.
- Comprehensive Clinical Medicine Self-Assessment (CCMSA)
The CCMSA uses information typically covered in clinical encounters. The content of the CCMSA items resembles the content of those in the multiple-choice component of Step 3 of the USMLE.
NBME research demonstrates that under certain circumstances there is a moderate relationship between performance on the CBSSA and CCSSA and subsequent Step 1 or Step 2 CK. US and International medical students and graduates may find these self-assessments to be valuable tools as they prepare for USMLE Step 1 and Step 2 CK.
- An individual performance profile with diagnostic feedback that highlights areas of strength and weakness
- A score interpretation guide with a conversion table that translates an assessment score to an approximated total score on the USMLE score scale (not available for CCMSA)
- The ability to review the correct answer for all items, and
- Longitudinal feedback provided when multiple assessments are completed
