Maybe your last practice exam didn't go the way you hoped. Maybe life happened: a family emergency, an illness, a rotation schedule that suddenly collided with your test date. Either way, you're staring at your Prometric confirmation and wondering if you can move it without making things worse.
You can. Rescheduling Step 1 is common, and it's a lot less dramatic than it feels in the moment.
Here's exactly how to do it, what it costs, and how to decide whether moving your date is the right call.
How Do You Reschedule USMLE Step 1?
To reschedule, go to the Prometric website, use your Prometric confirmation number to pull up your appointment, and choose a new date that falls inside your eligibility period. The fee depends on how far out you make the change. Under the schedule beginning July 1, 2026: 46 or more days before your test is free, 31 to 45 days costs $35, 6 to 30 days costs $100, and 5 or fewer days costs $158 for Step 1.
The two rules that matter most: your new date must stay within your eligibility period, and the earlier you decide, the less it costs. If you're learning how to reschedule USMLE Step 1 because you're unsure about your readiness, try to make the call before you hit that 46-day mark.
How to Reschedule USMLE Step 1, Step by Step
- Confirm your eligibility period. Check your scheduling permit or your registering organization's portal (NBME for US and Canadian MD/DO students, FSMB for IMGs). Your new date has to fall inside this window.
- Find your Prometric confirmation number. It's in the confirmation email Prometric sent when you first booked. You'll need it to access your appointment.
- Check seat availability before changing anything. Popular test centers fill up, especially during peak dedicated season. Look at open dates first so you know your options.
- Choose "reschedule," not "cancel." Rescheduling moves your existing appointment. Cancelling releases your seat, and you may not get a good one back.
- Pick your new date, time and test center. If your local center is booked, a nearby center with an open date can be worth the drive.
- Pay any change fee. The amount depends on how many days remain before your original appointment.
- Save your new confirmation. Make sure you receive an updated confirmation email, and double-check the date, time and address before closing the page.
You can also make changes by phone through Prometric's contact center if you run into trouble online, but the website is usually the fastest route. Check Prometric's site for the exact daily cutoff time for same-window changes so a late-night decision doesn't push you into a higher fee tier.
A Quick Checklist Before You Confirm
- Is the new date inside your eligibility period?
- Does it still meet your school's deadline for completing Step 1 before clerkships?
- Have you checked which fee tier you're in today, based on days remaining before your original appointment?
- Do you have a concrete plan for the extra weeks, not just more of the same?
- Have you told anyone who needs to know, such as your advisor or clerkship coordinator?
If you can answer yes to all five, go ahead and confirm. If not, sort out the gaps first, ideally the same day so you don't slip into a higher fee tier while you wait.

Use Day 46 as a Decision Point
Because changes 46 or more days out are free, it's worth building a deliberate checkpoint into your schedule around then. Take a CBSSA shortly before that mark and look honestly at your estimated probability of passing. If the trend is strong, keep your date with confidence. If it's shaky, moving now costs nothing.
Late Changes Aren't a Disaster
Even inside 30 days, $100 or $158 is far less than the cost of a failed attempt, which means a new $695 application plus more time and prep. If the data clearly says you're not ready, a late reschedule is still the cheaper option.
What If You Need a Date Outside Your Eligibility Period?
Prometric can only book you within your current eligibility period. If the date you need falls outside it, contact your registering organization (NBME or FSMB) about your options. An eligibility period extension may be available, typically for a fee and with limits, so check their current policy before assuming you can push your date as far as you'd like.
If you can't test within your eligibility period at all, you'll generally need to reapply and pay the $695 application fee again. Don't let your window quietly expire. If you're going to miss it, deal with it before the deadline rather than after.
Should You Reschedule? How to Decide
Let the Data Lead
Step 1 is pass/fail with a passing standard of 196, so the question is simple: are you reliably passing? Several consecutive CBSSAs with a high estimated probability of passing say yes. A borderline or falling trend says you need more time, and your school advisor should be part of that conversation.
Factor In the Stakes
In 2024, 91% of US MD first-time takers passed Step 1, compared with roughly 70% of repeaters. You're also limited to 3 attempts within 12 months and 4 total. A short delay to walk in prepared is almost always better than an attempt you weren't ready for.
Account for Your School's Timeline
Many schools set deadlines for completing Step 1 before clerkships begin. Before you move your date, confirm the new one still fits your school's requirements. If you're replanning your remaining weeks, our 8-week Step 1 study schedule can help you restructure.
What Most Students Get Wrong About Rescheduling
The first mistake is cancelling instead of rescheduling. Cancelling gives up your seat entirely, and finding a new one during peak season can be harder than expected.
The second is waiting for certainty. Students keep their date "just to see how next week goes," slide past day 46, and turn a free change into a paid one. Decide on data at a planned checkpoint, not on a hunch at the last minute.
The third is rescheduling on anxiety alone. Nearly everyone feels unready before Step 1. If your practice exams consistently show you're passing, pushing your date often just stretches out the stress.
The fourth is moving the date without changing the plan. Extra weeks only help if you use them differently. Knowing how to reschedule USMLE Step 1 is the easy part; using the time well is what actually changes the outcome.
Making Your Extra Weeks Count
If you've moved your date, the next move is targeted practice on the areas your CBSSAs keep flagging. The Step 1 Question Bank from MedSchoolBro gives you 2,500+ NBME-style questions and 6 CBSE-style diagnostic exams, so you can work your weak systems and check progress before your new test day.
Frequently Asked Questions
Can I reschedule Step 1 more than once? Yes, as long as the new date stays within your eligibility period. Each change is subject to the Prometric fee schedule based on how close you are to your current appointment, so repeated late changes add up.
What happens if I miss my Step 1 appointment? If you don't show up and didn't reschedule, you generally lose that appointment and may need to reapply and pay the application fee again. If something urgent happens, contact Prometric and your registering organization as soon as possible.
Does rescheduling count as an attempt? No. Moving your appointment isn't an exam attempt. The attempt limits (3 within 12 months, 4 total per Step) apply to exams you actually sit for.
Will rescheduling get harder in the future? Starting January 2029, USMLE is moving to Designated Testing Dates with fewer administrations per year. Students testing then should expect less flexibility, so planning a realistic date from the start will matter even more.
