This guide reflects the USMLE Step 1 information and testing procedures available at the time of review. Fees, eligibility policies, registration procedures and testing arrangements can change, so applicants should confirm important details with the official USMLE, FSMB and ECFMG sources before applying.
USMLE Step 1 is the first examination in the United States Medical Licensing Examination sequence and focuses on the basic sciences that form the foundation of medical practice. For exams administered from May 14, 2026 onward, the test uses the updated delivery software with 14 blocks of up to 20 questions each in an approximately eight-hour testing session. Step 1 is reported as pass/fail, rather than with a three-digit score.

What Is USMLE Step 1?
USMLE Step 1 assesses whether an examinee understands and can apply important concepts of the sciences basic to the practice of medicine. The examination emphasizes scientific principles and mechanisms underlying health, disease and modes of therapy.
Although it is commonly described as a “basic science exam,” Step 1 is not simply a test of memorized facts. The official content description explains that many questions require examinees to interpret graphics and tables, identify normal and pathological specimens, and solve problems by applying basic science principles.
The examination is constructed around an integrated content outline. Instead of treating every discipline as an isolated subject, the test can combine foundational science with organ-system and disease-process questions.
Who Is Eligible for Step 1?
Eligibility depends primarily on the medical school program in which you are enrolled or from which you graduated. USMLE eligibility requirements apply both when you apply and on the day of your examination.
According to the current USMLE eligibility rules, Step 1 applicants generally fall into one of these categories:
- A medical student officially enrolled in, or a graduate of, a U.S. medical school leading to an MD degree accredited by the Liaison Committee on Medical Education (LCME).
- A medical student officially enrolled in, or a graduate of, a U.S. medical school leading to a DO degree accredited by the Commission on Osteopathic College Accreditation (COCA).
- A medical student officially enrolled in, or a graduate of, a medical school outside the United States that is listed in the World Directory of Medical Schools as meeting ECFMG eligibility requirements and satisfies the applicable ECFMG criteria.
Meeting a general medical-school category does not automatically mean that every applicant can register immediately. Additional eligibility verification can apply, particularly to international medical students and graduates.
Step 1 Eligibility for International Medical Students and Graduates
International medical students and graduates should pay particular attention to the distinction between USMLE registration and ECFMG Certification eligibility.
Following the 2026 USMLE service transition, students and graduates of medical schools outside the United States apply for Step 1 through FSMB. ECFMG, however, continues to determine whether international applicants are eligible for ECFMG Certification, and that eligibility remains an important requirement for taking USMLE examinations.
For an international medical student, ECFMG's eligibility process includes verification that the applicant is currently enrolled in an eligible medical school and will have completed the basic medical science component of the school's curriculum by the beginning of the selected examination eligibility period.
For an international medical school graduate, the certification process involves medical education credential requirements, including primary-source verification where required.
| Applicant type | Step 1 registration route | Important eligibility consideration |
|---|---|---|
| Eligible U.S. medical student/graduate | NBME | Must meet the applicable LCME or COCA eligibility category. |
| International medical student | FSMB | Must satisfy the relevant ECFMG eligibility requirements, including enrollment and basic-science requirements. |
| International medical graduate | FSMB | Must satisfy applicable ECFMG Certification eligibility and medical-education requirements. |
How to Register for USMLE Step 1
The registration process changed in 2026. Applicants should use the registration organization that applies to their medical-school category rather than older instructions that direct international applicants to register their Step examination directly through ECFMG.
For students and graduates of eligible U.S. medical schools
- Review the current USMLE eligibility requirements.
- Apply for Step 1 through NBME using the current MyUSMLE process.
- Pay the applicable examination fee.
- Receive the scheduling permit and eligibility period after registration is completed.
- Schedule the examination through Prometric.
For students and graduates of medical schools outside the United States
- Establish the required FSMB account and complete the applicable identity verification process.
- Have an accepted Application for ECFMG Certification where required for access to the Step 1 application.
- Complete the relevant eligibility verification process.
- Apply for Step 1 through the FSMB USMLE portal.
- Pay the required fee and wait for application approval and scheduling information.
- Use the scheduling permit to arrange the examination with Prometric.
USMLE Step 1 Exam Pattern
For Step 1 examinations administered on or after May 14, 2026, the new test delivery software divides the examination into shorter blocks while keeping the overall number of questions and exam-day duration essentially unchanged.
| Feature | Step 1 from May 14, 2026 |
|---|---|
| Exam type | Computer-based, multiple-choice examination |
| Maximum total items | Up to 280 |
| Number of blocks | 14 |
| Maximum items per block | 20 |
| Time per block | 30 minutes |
| Testing session | Approximately 8 hours |
| Minimum break allowance | 55 minutes |
| Optional tutorial | 5 minutes |
| Score reporting | Pass/fail |
The shorter blocks change how candidates manage time. Because questions cannot be carried forward or revisited after a block closes, preparation should include practice with the current testing interface and realistic timed blocks.
The official USMLE Step 1 question-format guidance describes the primary format as single-best-answer questions. A patient-centered vignette is typically followed by several response options, and examinees must select the best answer.
What Does Step 1 Test?
Step 1 uses an integrated content outline organized around organ systems and processes. The official specifications provide ranges rather than a fixed list of questions that every examinee will receive.
Current system-level content ranges include:
| Content area | Approximate official range |
|---|---|
| Human Development | 1–3% |
| Blood & Lymphoreticular/Immune Systems | 9–13% |
| Behavioral Health & Nervous Systems/Special Senses | 10–14% |
| Musculoskeletal, Skin & Subcutaneous Tissue | 8–12% |
| Cardiovascular System | 7–11% |
| Respiratory & Renal/Urinary Systems | 11–15% |
| Gastrointestinal System | 6–10% |
| Reproductive & Endocrine Systems | 12–16% |
| Multisystem Processes & Disorders | 8–12% |
| Biostatistics & Epidemiology/Population Health | 4–6% |
| Social Sciences: Communication and Interpersonal Skills | 6–9% |
USMLE notes that percentages can change and that no single examination form necessarily contains every topic listed in the outline. The official content outline should therefore be treated as the primary reference for planning preparation.
Major disciplines
The current discipline specifications include pathology, physiology, nutrition, gross anatomy and embryology, microbiology, pharmacology, behavioral sciences, biochemistry, histology and cell biology, immunology, and genetics. These percentages can overlap because Step 1 questions are deliberately designed to be integrative.
Step 1 Scoring and Results
Step 1 has been reported as pass/fail only for examinations administered on or after January 26, 2022. Modern Step 1 score reports therefore do not provide examinees with a three-digit Step 1 score.
The historical three-digit passing standard was 196, but the current Step 1 outcome is reported as pass/fail. That historical number should not be treated as a current Step 1 score-reporting format.
USMLE states that computer-based examination results are typically available within several weeks, although applicants are advised to allow additional time because score reporting can sometimes take longer. The 2026 service transition also means that international examinees receive their score-report notification through FSMB's USMLE system.
USMLE Step 1 Cost and Fees
The official 2026 and 2027 Step 1 application fee is US$695.
For students and graduates of medical schools outside the United States, the official USMLE fee information lists an additional US$210 region fee for examinations taken outside the United States and Canada. This region fee is separate from the USMLE application fee.
| Cost item | Current amount / status |
|---|---|
| Step 1 application fee | US$695 for 2026 and 2027 fees |
| Region fee outside U.S. and Canada | US$210 |
| Study resources | Varies by resources selected |
| Travel/accommodation | Varies by testing location |
| Rescheduling | May incur Prometric fees depending on timing |
The application fee is not the same thing as the complete cost of taking Step 1. Depending on the applicant's circumstances, the overall budget may also include study materials, travel, accommodation, credential-related costs and other administrative expenses.
Prometric appointment changes made sufficiently far in advance may have no fee, while changes closer to the scheduled appointment can incur charges. Current USMLE guidance states that the applicable fee depends on how close the appointment change is to the scheduled test date.
How to Prepare for Step 1
Step 1 preparation should combine foundational understanding, active recall, question-based learning and repeated review. There is no single official preparation schedule that guarantees success, so the most useful study plan is one that matches your current knowledge, available time and weaknesses.
1. Start with the official content outline
Use the current USMLE Step 1 content outline to understand what the examination is designed to assess. The outline should guide your coverage rather than become a checklist for memorizing every possible detail.
2. Build foundational understanding
Prioritize mechanisms. For example, instead of memorizing a disease as an isolated list of findings, connect its pathology, physiology, pharmacology and clinical presentation. Step 1 questions frequently require the examinee to move from a clinical vignette to an underlying scientific mechanism.
3. Use questions as a learning tool
Question banks can help identify knowledge gaps and expose you to the reasoning required by single-best-answer questions. After answering a question, review why the correct answer is correct and why the alternatives are less appropriate.
4. Track recurring weaknesses
Maintain a simple error log. Useful categories include:
- Knowledge gap
- Misread question
- Incorrect interpretation of a laboratory or imaging finding
- Confusion between similar diseases
- Calculation or biostatistics error
- Changed an initially correct answer without sufficient reason
- Timing problem
5. Practise the current software
The 2026 Step 1 software changed the block structure from seven longer blocks to fourteen shorter blocks. Candidates should use the current official interactive testing experience so that the interface and shorter block format are familiar before test day.
A Practical Step 1 Study Roadmap
The following is a practical framework rather than an official USMLE requirement.
| Stage | Main objective | Suggested activity |
|---|---|---|
| Foundation | Understand core mechanisms | Review basic sciences systematically and connect them to disease. |
| Integration | Connect disciplines | Combine pathology, physiology, pharmacology, microbiology and related subjects. |
| Question practice | Improve application | Work through timed and untimed question sets and analyse mistakes. |
| Weakness repair | Close recurring gaps | Target the subjects and question types responsible for repeated errors. |
| Final practice | Build exam readiness | Use realistic timed sessions and the current official testing interface. |
What to Expect on Exam Day
Step 1 is administered at Prometric test centers. Your scheduling permit and Prometric appointment information should be reviewed carefully before the examination.
The current Step 1 format provides up to 280 questions across fourteen 30-minute blocks. You receive a minimum break allowance of 55 minutes, and the optional tutorial takes five minutes. The exact number of questions on a particular block can vary but cannot exceed 20.
Because blocks close as you progress, time management matters. You should not plan on returning to questions from a completed block. Practising with the current software can help reduce avoidable interface and pacing problems.
