USMLE Eligibility: Who Can Sit Each Step

You have to be eligible when you apply and again on the day you sit. Those are two separate moments, and people are caught out by the second one!

Below is who qualifies for each Step, what changes for international graduates, and the attempt limits that end USMLE eligibility permanently. All of it checked against the Bulletin this month 🙂

USMLE eligibility for Step 1 and Step 2 CK

Three categories qualify for USMLE eligibility, and you have to be in one of them at both moments. If you are in one, you are in!

There is no route in without a medical school. The exam is a licensing examination rather than an open assessment, so enrollment or a degree is the gate!

Step 3 asks for more

USMLE eligibility for Step 3 adds three requirements on top, and by then you will have met two of them already 🙂

• Passing scores on Step 1 and Step 2 CK. No exceptions.
• An MD or DO degree from an LCME- or COCA-accredited US school, or the equivalent from a listed school outside the US.
• ECFMG certification, valid and unexpired, if you trained outside the US.

The USMLE program also recommends completing, or nearly completing, at least one postgraduate training year in an accredited US program before sitting it 🙂

Costs for each Step are on our USMLE cost page.

USMLE eligibility for international graduates

USMLE eligibility itself is no harder by this route, just different. What is harder is everything after it!

• Your school has to be listed in the World Directory of Medical Schools as meeting ECFMG eligibility requirements.
• You register through ECFMG rather than the NBME, and their own criteria apply on top.
• ECFMG certification is required before Step 3 and before entering US residency.
• Testing abroad adds a surcharge, $210 on Step 1 and $235 on Step 2 CK.

In 2025, 75% of first-time takers from schools outside the US passed Step 1, against 93% from US MD schools. Our pass rate page has the full picture!

The attempt limits that end eligibility

Four attempts at any one Step, and a fourth failure ends USMLE eligibility for the whole sequence. Read that again, because it is the rule people discover too late.

• Four or more attempts at a Step without passing, and you are ineligible for any Step in the USMLE sequence. Not just that one.
• Incomplete attempts count. So do attempts at the discontinued Step 2 Clinical Skills.
• No more than three attempts at the same Step in any 12-month period.
• A fourth attempt must be at least 12 months after your first attempt at that Step, and at least 6 months after your most recent one!

When your eligibility changes

USMLE eligibility is a status rather than a permission, and it can lapse between applying and sitting!

• Tell whoever registered you, promptly. Failing to report a change can be treated as irregular behavior, which carries a permanent annotation on your transcript.
• Dismissal or withdrawal ends eligibility, even while you are appealing the school's decision.
• A leave of absence needs checking with whoever registered you, before you apply and again before you test.
• Sitting a Step you were not eligible for means the result may not be reported, or may be canceled after the fact.

The rules are set out in the Bulletin of Information, which you agree to at registration 🙂

Retaking something you already passed

You cannot, with one narrow exception.

A passed Step can only be retaken to satisfy a time limit set by a US medical licensing authority for completing the whole sequence, or by another authority the USMLE program recognizes.

If you do retake a passed Step 1 or Step 2 CK for that reason and fail it, you are no longer eligible for Step 3, because Step 3 eligibility rests on your most recent administration rather than your best one!

Eligibility periods and state time limits

Two clocks run on your USMLE eligibility, and different people set them.

• Your eligibility period is a three-month window chosen at application. Test inside it or reapply and repay.
• State time limits are set by individual medical boards, and many require the whole sequence completed inside a fixed number of years.
• Combined-degree students such as MD/PhD have documented exceptions to those time limits.

State-specific requirements are published by the FSMB, and they vary enough that the only safe answer is your own board's. Our Step 1 dates page covers the eligibility period in detail!

USMLE eligibility, common questions

Can you take the USMLE without going to medical school?

No. You must be enrolled in, or a graduate of, a qualifying MD, DO or listed international medical school at application and on test day.

What are the USMLE eligibility requirements for international students?

Your school must be listed in the World Directory of Medical Schools as meeting ECFMG eligibility requirements, you register through ECFMG, and certification is needed before Step 3.

How many attempts does USMLE eligibility allow?

Four, including incompletes. Four attempts without passing makes you ineligible for every Step in the sequence.

Do nursing or PA graduates meet USMLE eligibility?

No. Eligibility rests on a medical degree program, and no other qualification opens the sequence.

Does a leave of absence end my eligibility?

Not automatically, and it does need checking with whoever registered you, before you apply and again before you test.

Can I sit Step 1 after graduating?

Yes. Graduates of qualifying schools remain eligible for Step 1 and Step 2 CK. Our USMLE overview covers how the Steps fit together!
