The International Foundations of Medicine (IFOM®) program allows you to measure your knowledge and compare your performance against examinees around the world.

Medical schools and other organizations use the IFOM exams to help select candidates for exchange and training programs, award regional and national certifications, and prepare students for the USMLE® Step 1 and Step 2 Clinical Knowledge exams.

Exam Content

The IFOM program is comprised of three assessments, including the Basic and Clinical Science exams and a Clinical Science Self-Assessment.

The International Foundations of Medicine (IFOM) Basic Science Exam is a comprehensive examination designed to assess examinees’ knowledge of the basic medical sciences.

The exam comprises 160 multiple-choice questions, most of which are presented in clinical vignette style, in order to assess your ability to not just recall but also apply basic medical science knowledge.

The following content areas are covered:

  • Anatomy
  • Biochemistry
  • Histology and Cell Biology
  • Microbiology
  • Organ Systems
  • Pathology
  • Pharmacology
  • Physiology

The International Foundations of Medicine (IFOM) Clinical Science Exam assesses the medical knowledge and understanding of clinical science considered essential for the provision of safe and effective patient care.

The exam comprises 160 multiple-choice questions presented in clinical vignette style to assess your ability to not just recall but also apply knowledge in clinical contexts. 

The following content areas are covered:

  • Family Medicine
  • Medicine
  • Obstetrics and Gynecology
  • Pediatrics
  • Psychiatry
  • Surgery

The International Foundations of Medicine (IFOM) Clinical Science Self-Assessment assesses your knowledge of the clinical sciences in advance of taking the IFOM Clinical Science Exam.

It covers the same content as the Clinical Science Exam and includes 80 multiple-choice questions.

Taking the Exam

While many administrations of the IFOM exams are arranged and conducted by schools and other institutions at their sites and on behalf of their examinees, the NBME also makes the IFOM Clinical Science Exam and the IFOM Basic Science Exam available for individual administrations two times per year.

Individuals can use this option in a variety of circumstances, including:

  • Personal benchmarking or practice
  • Application to a residency program, exchange program, or other opportunity that accepts IFOM scores
  • The examinee’s school or program is conducting an on-site IFOM administration but the examinee is separated geographically from their institution

The IFOM Basic and Clinical Science Exams are available to individuals, in English only, at participating Prometric Test Centers located in approximately 50 countries around the world.

There are two test administration periods per year; registration for each administration period is open for 4 weeks. The 2020 test window will remain open until November 6.

Please note the 2021 dates for registration, status verification, and testing, below:

Preparing for Your Exam

Examinees can familiarize themselves with the IFOM Basic & Clinical Science Exam web-based format by using the free 20-question online practice exams. Both timed and untimed versions are available.

In addition to the IFOM Clinical Science Practice Exam, the IFOM Clinical Science Self-Assessment Exam is an 80-question web-based exam built to the same content blueprint as the IFOM Clinical Science Exam. Learn more on the Self-Assessment page

Note: The practice exams are NOT intended to assist examinees in preparing for the content of the exam; it is only intended to familiarize examinees with the style and format of test questions they are likely to see on the IFOM exams if administered on the web.

Score Reports

Students who take the IFOM Basic Science Exam or the Clinical Science Exam independent of a school or other organization receive an Examinee Performance Report, which includes the examinee’s total test score and performance profiles outlining areas of strength and weakness, as compared to the International Comparison Group, in each content area measured by the exam.

Those whose IFOM Basic Science Exam or the Clinical Science Exam score is at or greater than the corresponding approximate USMLE Step examination passing score (Step 1 for IFOM BSE, Step 2 CK for IFOM CSE) also receive a Certification in Basic/Clinical Science Knowledge.

Interpretation guides are provided with the Examinee Performance Report. These help examinees understand all aspects of their score and include a score table that allows examinees to compare their performance on the IFOM Basic Science Exam or Clinical Science Exam to USMLE Step 1 or Step 2 Clinical Knowledge.
