Purchase self-assessment vouchers to support your students on their learning journey


The NBME® Self-Assessment Services Voucher Program is offered to medical schools, residency programs, and medical education organizations interested in purchasing self-assessments for their students planning to take the USMLE®, a Clinical Science Subject Exam, or the IFOM® Exam.

Early administration of an NBME Self-Assessment can help you identify students who may be at risk of not passing their end-of-course or licensing exam and deliver targeted remediation, while regular testing can give insight into their progress to make the appropriate adjustments.  

Additionally, by providing self-assessments for your students, you can help them to:

  • Evaluate their readiness and practice for their upcoming exam
  • Familiarize themselves with NBME-style questions 
  • Target their studies using diagnostic feedback that highlights areas of strength and weakness
  • Estimate their approximate score on their upcoming exam
  • Reinforce their knowledge and maximize study time with answer explanations*

*Available for the Comprehensive and Clinical Mastery Series Self-Assessments
