USMLE Step 2 CK Passing Score: What Changed and How To Prep

The USMLE® Step 2 CK passing score is 218 as of July 1, 2025, increased from the previous minimum of 214. This 4-point increase means you need approximately 4 to 6 more correct answers across the exam’s 318 maximum scored items. The change applies to everyone testing from July 2025 onward, including retake candidates.

While that number might spike your anxiety, consider this: the average score for US and Canadian first-time takers is around 250, placing the passing threshold at roughly the 3rd percentile. Most students pass with comfortable margin. Whether 218 changes your study strategy depends on where you currently score and what specialty you are targeting. This article covers both, along with what else changed for Step 2 CK in 2026.

What is the USMLE Step 2 CK passing score in 2026?

The minimum passing score is 218 on the three-digit scale. The USMLE Management Committee announced this change on June 16, 2025, with an effective date of July 1, 2025.

This was not a surprise move. The Committee conducts thorough reviews every three to four years, using independent panels of physicians and educators, surveys of residency program directors, and analysis of examinee performance trends. The last review raised the score from 209 to 214 in July 2022. Before that, the passing score had been 209 for several years.

Passing score timeline:

In the last two review cycles, the passing score increased from 209 to 214 and then from 214 to 218.

What does a score of 218 actually mean?

A score of 218 sits well below the average for US and Canadian first-time takers. To put that in context, the national mean is around 250, and a standard deviation is roughly 15 points. Scoring 218 means performing more than two standard deviations below the mean.

For US MD students, the practical impact is small. The first-time pass rate has been 98% in recent testing cycles, and a 4-point bump in the threshold is unlikely to change that dramatically. The students most affected are those scoring in the 214 to 217 range; candidates who previously passed by a thin margin now fall short.

For IMGs, the stakes are higher. The first-time pass rate for non-US/Canadian IMGs is approximately 90%, with repeaters at 64%. A 4-point increase disproportionately affects candidates near the borderline. If your NBME practice scores are hovering in the low 210s, the margin for error just got tighter.

Score percentile reference:

Why did the Step 2 CK passing score change?

The USMLE Management Committee stated that the increase reflects “current expectations concerning knowledge and skills needed to support effective medical practice and patient care.” Two factors explain the increase.

First, mean scores have been climbing. The average for US and Canadian first-time takers has risen from roughly 248 to 250 in recent years. When students perform better overall, the Committee raises the floor to maintain a meaningful competency threshold.

Second, Step 2 CK now carries more weight than ever. Since Step 1 moved to pass/fail in January 2022, Step 2 CK became the first numerically scored exam in the USMLE sequence. Residency programs lean on it heavily for screening, making the passing standard more consequential.

The passing-score update did not change the exam format or published test length. Only the passing standard moved.

How to adjust your study strategy for the higher score

If you were already scoring above 230 on practice exams, the 218 change does not require a strategy overhaul. Your margin is still comfortable. Focus on your target score for residency competitiveness, not the passing threshold.

If your practice scores are in the 210 to 225 range, these adjustments matter (see our Step 2 CK study schedule for detailed week-by-week plans):

Strengthen your weakest subjects first. Step 2 CK weights clinical medicine heavily (Medicine accounts for 50 to 60% of content, Surgery 25 to 30%). Gaining 10 points in your weakest domain is easier than squeezing 2 more out of a strong one.

Take NBME Self-Assessments seriously. Forms 11 and 13 are considered the most predictive, with Form 11 widely regarded as the most predictive among available self-assessments. Take at least two timed assessments in the final four weeks of preparation. If your NBME score is within 10 points of 218, postpone your exam and study longer.

Prioritize Qbank completion over passive review. Active recall through practice questions is the single most efficient way to raise your score. Aim for at least 80% completion of a major Qbank before your test date.

Build stamina for the full 9-hour day. Eight blocks of 60 minutes each, with up to 318 questions. Mental endurance is a real factor in borderline scores. Practice full-length timed sessions regularly in the final two weeks.

What score do residency programs actually want?

Passing with a 218 gets you a license. It does not get you a competitive residency application. The gap between the passing score and what programs expect varies dramatically by specialty.

Mean Step 2 CK scores for matched US MD seniors (2024 NRMP data):

The overall mean for all matched US MD seniors is 250.4 (SD = 13.2).

For IMGs, the numbers tell a sharper story. US IMGs who matched had an average score of 242, while those who did not match averaged 234.5. That 7.5-point gap underscores how much each point matters when you are competing for limited spots.

If you are targeting a competitive specialty, your real benchmark is not 218. Aim for at least 240 to be in the conversation, and 250 or above to be competitive.

NBME practice exams: how to predict your real score

NBME Self-Assessments are the best available predictor of your actual Step 2 CK score, but they come with caveats.

What to trust:

• NBME Form 11 is widely considered the most predictive self-assessment
• Forms 13 and 15 reflect the most recent content updates
• Scores taken one to four weeks before the real exam are typically accurate within a range of 5 to 7 points

What to watch out for:

• Some students score significantly higher on the real exam than their NBME prediction
• Treat any single NBME score as a rough estimate, not a precise prediction
• The USMLE does not publish exact raw-to-scaled conversions, so no calculator gives you a precise prediction

The practical rule: if your NBME practice score is below 225 to 228, treat the passing score as a real risk and extend your preparation. If you are consistently scoring above 235, passing is very likely secured; shift your focus to maximizing your score for residency applications.

FAQs: Step 2 CK passing score

Does the 218 passing score apply if I took the exam before July 2025?

No. Exams taken before July 1, 2025 are scored against the previous standard of 214.

How many additional questions do I need to get right compared to the old score?

Approximately 4 to 6, though the USMLE does not publish exact raw-to-scaled conversions. The score is scaled, not a direct percentage of correct answers.

Will more students fail with the 218 threshold?

Post-change pass rates have not been published yet. Based on score distributions, the increase will primarily affect borderline candidates, particularly IMGs and repeat takers. The impact on US MD first-time takers is expected to be minimal.

Is the exam itself harder in 2026?

No. The exam content, format, and total number of items remain unchanged. Only the passing threshold moved.

Can I retake Step 2 CK if I fail?

Yes. You may take Step 2 CK no more than four times within a 12-month period and no more than six times total. Retakers must wait a minimum of 60 days between attempts.

How long are Step 2 CK scores valid?

Score reports can be accessed for 120 days after release; the score itself remains on your permanent USMLE transcript for residency applications.
