USMLE Step 1 2026 format changes: 14 blocks and 30-minute pacing

Since May 14, 2026, USMLE Step 1 has been split into 14 blocks of up to 20 questions, with 30 minutes for each block. Before that, it was 7 blocks of up to 40 questions, with 60 minutes each. The content, the 280 questions and the 8-hour day are the same, and you still get about 90 seconds per question. What changes is the rhythm of the day: twice as many blocks, more transitions, and a bigger minimum break allowance of 55 minutes.

What changed on USMLE Step 1 on May 14, 2026?

The USMLE program moved Step 1 to new test delivery software on May 14, 2026. The official launch notice lists the change as 7 blocks becoming 14, 40 items per block becoming 20, and 60 minutes per block becoming 30.

The Step 1 exam page now describes the exam like this: it is "divided into fourteen 30-minute blocks and administered in one 8-hour testing session." It adds that the number of questions per block "may vary, but does not exceed 20."

The software itself also looks different. The USMLE program lists an updated design, better keyboard navigation, a new settings menu and the option to adjust contrast on each image. The program has published a New Step 1 interactive testing experience so you can try the interface before test day. Run through it at least once, so the screens aren't new to you on the day.

What stayed the same on Step 1

Almost everything you study for. The notice is direct about it: "The exam content, total number of items, and overall exam day duration will not change."

So your content plan doesn't need rewriting. The same systems and disciplines are tested, in the same 280 questions, on the same 8-hour day. The math works out exactly: 14 blocks of 30 minutes is 7 hours of testing, and 55 minutes of break plus the 5-minute tutorial makes up the eighth hour.

Review rules are also unchanged. You can only review questions inside the block you're working on, and once a block is closed you can't go back to it. Scoring hasn't changed either. Step 1 has been reported as pass/fail since January 26, 2022, with a passing standard of 196 on the three-digit scale.

How to pace 20 questions in 30 minutes

The time per question is the same as before: 30 minutes for 20 questions is 90 seconds each, just as 60 minutes for 40 questions was. The difference is how much room you have to recover.

In a 40-question block, one stubborn 4-minute question could be absorbed over the next 39. In a 20-question block, there are only 19 left to win that time back. A couple of slow questions early on can squeeze the end of a short block hard. Checkpoints every 5 questions help you catch this early.

A few habits that suit short blocks:

• Aim to be slightly ahead at each checkpoint, so you finish with a few minutes to revisit marked questions.
• If a question passes about 2 minutes, pick your best answer, mark it and move on.
• Answer every question before time runs out, since a blank answer can't earn credit.
• Treat each block as a fresh start. A hard block tells you nothing about the next one.

How to plan break time across 14 blocks

You have at least 55 minutes of break time, spread across 13 gaps between blocks. Two rules from the official break time page shape your plan.

First, finishing early helps you. "If you complete the tutorial or other testing blocks early, the remaining time will be added to your total break time." Skipping the 5-minute tutorial gives you about 60 minutes in total.

Second, going over costs you. If you exceed your break time, the excess is taken from your total testing time, which means less time for questions later. The time between blocks counts as break time even if you stay in your seat, and leaving the room means signing out, then signing in again with your ID. Budget about a minute for every gap, plus a few more whenever you step out.

Here's one plan that fits 55 minutes with a small buffer:

Your plan may look different. Some people prefer a short break after every 2 blocks. Others like to save a longer one for the second half, when fatigue builds. Whichever you choose, write it down and test it on a full practice day. You can download the break planner as a spreadsheet and change the minutes to suit you.

How to set up your question bank for the new blocks

The fastest way to retrain is to make every practice block look like a real one. Most question banks let you choose the number of questions in a block and switch on timed mode.

1. Set every block to 20 questions in timed mode. If your bank lets you set a custom time, use 30 minutes.
2. Check your pace at questions 5, 10 and 15 against the checkpoint table above.
3. Review each block straight after you finish it, while your reasoning is still fresh.
4. Once a week, do several blocks back to back with your planned breaks in between, building from 4 blocks up to 7.
5. One to two weeks before test day, do a full-length practice day: 14 blocks of 20 with your full break plan.

NBME self-assessments now run on the same software as the real exam. The USMLE program confirmed in May 2026 that "NBME's self-assessments and other practice materials are already delivered with this software." Before you start a form, check how its sections are split. If they're longer than 20 questions, use 30-minute checkpoints inside each section so your pacing still matches test day.

Timed practice shows you where you lose time. Medly can help with the next part: understanding why. When a question slows you down, Medly's AI tutor can walk you through the reasoning step by step, so the same type of question takes less time when you meet it again. You can read more about Medly.

How to retrain your pacing before test day

If you built your timing around 40-question blocks, give yourself time to adjust. Two to three weeks of 20-question timed blocks is usually enough for the 90-second rhythm to feel natural.

Start with single blocks and focus only on the checkpoints. Then link blocks together so you practice the short reset between them, which is the new skill this format asks for. In the last week, keep the same block size and break plan every day, so test day feels like another practice session.

Pair timed blocks with active review of what you get wrong. A short daily set of questions on your weakest topics, worked through with Medly, keeps your content and your pacing improving together.

Frequently asked questions

Did USMLE Step 1 change in 2026?

Yes. Since May 14, 2026, Step 1 has 14 blocks of up to 20 questions, with 30 minutes per block. The content, the 280 questions and the 8-hour day haven't changed.

Do I get less time per question on the new Step 1?

No. You still have about 90 seconds per question. The time is split into shorter blocks, so there is less room to make up time lost on a slow question.

How much break time do you get on Step 1 now?

At least 55 minutes, up from 45. Skipping the 5-minute optional tutorial and finishing blocks early both add time to your break pool.

Did the Step 1 passing score change in 2026?

No. The 2026 software notices don't mention scoring. Step 1 is still reported as pass/fail, with a passing standard of 196 on the three-digit scale.

Can you go back to an earlier block on Step 1?

No. You can only review questions in your current block, the same rule as before the change.

Did Step 2 CK change too?

Yes. Since May 7, 2026, Step 2 CK has 16 blocks of 18 to 20 questions, with 30 minutes per block. It still has 316 questions over a 9-hour day.
