The United States Medical Licensing Examination (USMLE) is a three-step examination program for medical licensure in the United States, sponsored by the Federation of State Medical Boards (FSMB) and the National Board of Medical Examiners (NBME). Individuals with a Doctor of Medicine (MD) degree are required to pass the USMLE for medical licensure. Those with a Doctor of Osteopathic Medicine degree (DO) may take either the COMLEX-USA or the USMLE for medical licensure, while the COMLEX-USA is required for osteopathic licensure.
It is a standardized test that assesses a medical student's knowledge of basic science concepts and their application to clinical medicine. The exam is divided into three components required for medical licensure in the United States and is typically taken by students after their second year of medical school. States may enact additional testing and/or licensing requirements.
History
The USMLE was created in the early 1990s. The program replaced the multiple examinations, including the National Board of Medical Examiners Part Examination program and the Federation of State Medical Boards Federation Licensing Examination (FLEX) program, that offered paths to medical licensing in the medical profession.
The examination was originally imparted using pencil and paper. In 1999, computerized examination delivery was included. During the COVID-19 pandemic, USMLE Step 2CS was initially suspended and later discontinued.
A review of the program was enacted in 2009. USMLE claimed it was done with the intention of orienting the examination to support the licensing decisions made by medical boards, transitioning the exam to a competencies schema and emphasizing the importance of scientific foundations of medicine throughout the examination sequence. They also aimed to continue the assessment of clinical skill and interpretation of clinical information.
While traditionally, students took the USMLE Step 1 exam after completing foundational sciences and before core clinical clerkships, in the past decade, a growing number of medical schools have reformed their curricula to have students take the USMLE Step 1 after core clinical clerkships or preliminary clinical training.
In response to concerns about the role of USMLE Step 1 scores in residency selection and the negative impact on medical student mental health, the United States Medical Licensing Examination (USMLE) announced significant changes to the exam in 2020. One of the major changes was the transition to a pass/fail scoring system from the previous three-digit score reporting system. The change was made to encourage a shift in focus from "high-stakes testing" to "learning and individual improvement", as well as to alleviate some of the stress associated with the exam. These changes were implemented starting in January 2022, with the first USMLE Step 1 scores reported in the pass/fail format in February 2022.
Generative AI models can now pass all steps of the exam.
Description and purpose
The United States Medical Licensing Examination (USMLE) is required for medical licensure in the United States by all graduates of M.D.-granting American medical schools as well as all graduates of international medical schools.
- Step 1: Assesses foundational medical science typically obtained during the first two years of medical school
- Step 2CK: Evaluates the applicant's knowledge of clinical medicine
- Step 3: Assesses the application of clinical knowledge to patient management
Previously, USMLE included a clinical skills portion called USMLE Step 2 Clinical Skills. It was discontinued during the COVID-19 pandemic. Step 1 and 2 are typically completed by U.S. medical students during medical school, while Step 3 is usually taken by the end of the first year of residency. While the USMLE Step 1 and Step 2 CK exams can be taken at Prometric test centers worldwide, the Step 3 can only be taken in the United States.
The USMLE is sponsored by the Federation of State Medical Boards (FSMB) and the National Board of Medical Examiners (NBME). They developed it originally to provide state medical boards in the United States with a common examination for all licensure applicants. However, over time it has also been extensively used by residency programs to predict residency performance and screen residents for selection during the National Resident Matching Program.
As of 2024, to be eligible for the United States Medical Licensing Examination (USMLE), candidates must meet specific criteria based on the step of the exam they are applying for:
Step 1 and Step 2 CK:
Candidates must fall into one of the following categories at the time of application and on the day of the examination:
- Medical Students or Graduates of U.S. or Canadian MD Programs:
- Must be officially enrolled in, or a graduate of, a U.S. or Canadian medical school program leading to the MD degree, accredited by the Liaison Committee on Medical Education (LCME).
- Medical Students or Graduates of U.S. DO Programs:
- Must be officially enrolled in, or a graduate of, a U.S. medical school program leading to the DO degree, accredited by the Commission on Osteopathic College Accreditation (COCA).
- Medical Students or Graduates of International Medical Schools:
- Must be officially enrolled in, or a graduate of, a medical school outside the U.S. and Canada that is listed in the World Directory of Medical Schools as meeting the Educational Commission for Foreign Medical Graduates (ECFMG) eligibility requirements, and must meet all other eligibility criteria of the ECFMG.
Step 3:
To be eligible for Step 3, candidates must:
- Have Passed Step 1 and Step 2 CK:
- Successfully obtain passing scores on both Step 1 and Step 2 CK.
- Hold an MD or DO Degree:
- Possess an MD or DO degree from an LCME- or COCA-accredited U.S. or Canadian medical school, or an equivalent MD degree from an international medical school listed in the World Directory of Medical Schools that meets ECFMG eligibility requirements and obtain ECFMG Certification.
- Meet Additional Criteria:
- Fulfill all other eligibility requirements as outlined in the USMLE Bulletin of Information.
The USMLE program also recommends that applicants for Step 3 have completed, or be near completion of, at least one year of postgraduate training in an accredited U.S. graduate medical education program that satisfies state board licensing requirements.

Step 1 is designed to test the knowledge learned during the basic science years of medical school as applied in the form of clinical vignettes. This includes anatomy, behavioral sciences, biochemistry, microbiology, pathology, pharmacology, and physiology, as well as to interdisciplinary areas including genetics, aging, immunology, nutrition, and molecular and cell biology. Epidemiology, medical ethics and questions on empathy are also emphasized. Each exam is dynamically generated for each test taker; while the general proportion of questions derived from a particular subject is the same, some test takers report that certain subjects are either emphasized or deemphasized.
The USMLE Step 1 exam underwent a significant change in its scoring system in 2022, transitioning from a three-digit numeric score to a pass/fail system. Prior to this change, students received a score ranging from 1 to 300, with most scores ranging from 140 to 260. The passing score was 196, and the national mean and standard deviation were approximately 232 and 19, respectively. The scoring system used to be percentile-based, but in 1999 it was phased out in favor of the three-digit and two-digit scaled scoring system. Two-digit scores were eliminated from the score report in 2013.
Step 2 Clinical Knowledge (CK)
The exam is administered in a 9-hour single-day computer-based session. The session is divided into eight one-hour blocks of questions, a 15 minute tutorial and a 45 minute break. The 15-minute tutorial at the beginning of the exam is optional. The 45 minutes allowed for breaks can only be taken between sections at the discretion of the test taker. Both the unused tutorial time and time saved from finishing a test block early is added to the break time. Prior to 2020, the Step 2 exam consisted of both the CK ("Clinical Knowledge") portion, as well as a CS ("Clinical Skills") exam. However, the CS exam was put on hold in May 2020, and permanently discontinued in January 2021.
Step 2 CK includes test items in the following content areas: internal medicine, obstetrics and gynecology, pediatrics, preventive medicine, psychiatry, neurology, surgery, other areas relevant to provision of care under supervision. Most Step 2 CK test items describe clinical situations and require that you provide one or more of the following: diagnosis, a prognosis, an indication of underlying mechanisms of disease, the next step in medical care, including preventive measures.
The Step 2CK scores are reported in a 3 digit format with a range between 1 and 300. As of July 1, 2025, the passing score is 218. As of academic year 2023-2024, the mean CK score was 249 with a standard deviation of 15 for first-time takers from accredited medical schools in the United States and Canada. Approximately once every four years, the USMLE decides whether to change the recommended minimum passing score. At its May 2014 meeting, the Step 2 Committee conducted a review for USMLE Step 2 Clinical Knowledge (CK) and decided to raise the Step 2 minimum passing score to 209 for students taking the test after July 1, 2014. In 2022, the passing score was increased to 214, with an implementation date of July 1, 2022. In 2025, the passing score was increased to 218, with an implementation date of July 1, 2025.
Step 2 Clinical Skills (CS)
Step 2 Clinical Skills (Step 2 CS) of the USMLE as an exam administered to medical students/graduates who wish to become licensed physicians in the U.S. The examinees should also list pertinent positive and negative findings to support each potential diagnosis. USMLE Step 3 exams are delivered online but administered only at Prometric testing centers, which emphasize identity verification and security. Examinees must provide official photo identification and fingerprints as well as pass both metal detector and physical inspection every time they wish to enter the examination room. Materials allowed within the exam room are extremely limited and most require prior approval, including medical equipment. Examinees are on video surveillance during the examination. The test is available throughout the year to the examinees.
Since 2014 USMLE Step 3 can be taken on two non-consecutive days, instead of two consecutive days.
- Day 2 (Advanced Clinical Medicine [ACM]) is divided into six 45-minute blocks of MCQs, and 13 computer-based case simulations (CCS). Each ACM MCQ block includes 30 items. hold a medical degree. International medical graduates (IMGs) must also obtain certification by the Educational Commission for Foreign Medical Graduates (ECFMG) and fulfil all requirements in the USMLE Bulletin of Information.

Use in residency selection
The USMLE score is one of many factors considered by residency programs in selecting applicants. Many residency programs used a "cutoff" score for Step 1, below which applicants were unlikely to be considered. The NRMP Residency Program Director survey contains more information, both overall and by specialty, regarding "cutoff" scores (i.e., scores below which programs generally do not grant interviews). This, as well as the impact on student learning, cost of preparation, diversion of student time toward exam preparation, and desire to decrease racial bias, are amongst the reasons that the USMLE switched to Pass/Fail reporting of Step 1 at the beginning of 2022.
The medical community has criticized the USMLE and residency programs for using Step 1 scores as the main screening tool in selecting applicants for a residency interview. Residency program directors had historically utilized the scores as a means of filtering applications down to a more manageable number that allowed for a more thorough review of the remaining ones. A significant amount of residency program directors believe that the conversion to Pass/Fail will make applicant screening more arduous. Along with the USMLE Step 1, this test is a standardized measure of all applicants. The median USMLE Step 2 scores for graduates of U.S. Medical Schools for various residencies is published periodically by the NRMP in their "Charting Outcomes in the Match" documents
Changes to Step 1 scoring
Transition to Pass/Fail
It was announced on February 12, 2020, that beginning no earlier than January 2022, USMLE Step 1 would transition to a Pass/Fail scoring system. In July 2020, the USMLE announced that prior transcripts would not be retroactively altered."
While the NBME, USMLE, and FSMB were originally against these changes (which critics argued may have been from potential monetary loss), as of 2020 (and after the formation of InCUS), they have changed their stance in support of the public opinion. Humayun Chaudhry, the President of the FSMB, (who was originally in opposition to the Step changes), later said that "although the primary purpose of the exam is to assess the knowledge and skills essential to safe patient care, the new policies will "address concerns about Step 1 scores impacting student well-being and medical education." Because students put so much emphasis on getting a high USMLE Step 1 score, they often skimmed the medical school curriculum that they deemed to be not as relevant in order to get the maximum score on the USMLE Step 1. The USMLE published a list of InCUS participants. The ECFMG and AMA supported this transition as well. Notably, medical students and program directors were among parties with only a minority in favor of this change, despite being the most directly affected. Parties associated with medical schools, namely course directors and Deans were noted to have the most support for changes.
The USMLE parent organizations, including the AAFP, AMSA, This concern is validated by the aforementioned program director survey. These same schools are less likely to provide the same robust extracurricular opportunities, particularly in terms of highly valued research opportunities for these schools.
Step 2 CK is a three-digit-scored exam typically taken after the third year of medical school, which consists of clinical rotations in primary care fields. In February 2020, the Harvard Crimson wrote, "the fact that Step 2 is a more clinically relevant exam than Step 1, makes it a better proxy for clinical acumen." They were also criticized for reducing the length of the exam at newly established testing centers in some U.S. medical schools to be able to accommodate more students for testing as those changes would diminish the standardization of the tests. There were concerns that these issues would lead to many applicants having incomplete applications during the 2021 match season which would then negatively affect the ability of program directors to effectively evaluate candidates. These experimental questions accounted for 80 of the 280 on the exam, which would have led to the decreasing the total test taking time from 7–8 hours to 5–6 hours. Some commenters expressed concerns since this practice would have "destandardized" the text and test-takers would have been "experimented" on without consent.
Step 2 CS controversy
The Step 2 CS exam was added to the USMLE series in 2004 by the NBME and FSMB. However, the test garnered criticism for its high exam fee and need to travel to one of five testing sites. Even before the exam was rolled out, the American Medical Association raised serious concerns with the exam, both because it failed to provide students feedback and room for remediation and because there was no proof the exam actually accomplished its mission of protecting the public. A letter to the editor from the leadership of the NBME and the FSMB in response to the article highlighted the need to view the value of the Step 2 CS in terms other than just cost; specifically, they state that:<blockquote>Although (the authors') interest in cost is consistent with the current climate in health care, the 'value' referenced in their title is a function of quality as well as cost. They fail to fully consider the long-term effect of this assessment program on patient safety and satisfaction, societal expectations, and effective medical education.</blockquote>They also note that inclusion of Step 2 CS in the USMLE "brought the USMLE closer to meeting the expectations of the public that physicians exhibit competence in communicating with and examining patients." Depending on the threshold score, an African American was 3–6x less likely to be offered an interview."
"61% of minority applicants were accepted into an orthopaedic residency versus 73% of White applicants. White and Asian applicants and residents had higher USMLE Step 1. White applicants and matriculated candidates had higher odds of Alpha Omega Alpha membership compared with Black, Hispanic, and other groups.
In 2020, the American Academy of Family Physicians and the Association of American Medical Colleges expressed their support for changing Step 1 to pass or fail, in part to reduce racial bias. $1,000 for International medical graduates (IMGs)
- $660 for Step 2 CK for US/Canada students (increasing to $670 in 2024),
As part of a broader public plea for systemic changes to the improper use of USMLE exams, STAT wrote that this "multimillion-dollar industry has exploited the opportunity to extract thousands of dollars from already overly indebted students. Registering for STEP exams test cost $645–1300, while Step preparation materials and courses run much higher."
Katsufrakis & Chaudhry Comments
In December 2018, NBME President Peter Katsufrakis and FSMB President Humayun Chaudhry wrote in opposition of USMLE Step 1 changes in Improving Residency Selection Requires Close Study and Better Understanding of Stakeholder Needs: "If students reduce time and effort devoted to preparing for Step 1, they may indeed devote attention to other activities that will prepare them to be good physicians. This would arguably be an ideal outcome of such a change. However, if students were to devote more time to activities that make them less prepared to provide quality care, such as binge-watching the most recent Netflix series or compulsively updating their Instagram account, this could negatively impact residency performance and ultimately patient safety. We know that assessment drives learning, so another concern resulting from a shift to pass/fail scoring may be a less knowledgeable physician population."
