What is the USMLE Step 2 CK? A guide
The United States Medical Licensing Examination (USMLE) Step 2 Clinical Knowledge (CK) is a standardized test designed to assess the medical knowledge and clinical decision-making skills of medical students and graduates seeking licensure in the United States. Administered by the National Board of Medical Examiners (NBME) and the Federation of State Medical Boards (FSMB), it is a crucial component of the three-step USMLE series.
Purpose of USMLE Step 2 CK
Step 2 CK evaluates an examinee’s ability to apply clinical knowledge, medical concepts, and problem-solving skills in real-world medical scenarios. It focuses on the candidate’s ability to diagnose and manage patient cases in various medical settings.
Comparison with USMLE Step 1
Step 1 assesses basic medical sciences (e.g., anatomy, physiology, pathology).
Step 2 CK tests clinical knowledge and application in patient care settings.
Since Step 1 became pass/fail, Step 2 CK now plays a bigger role in residency selection.
Exam Format and Structure
The Step 2 CK is a one-day, computer-based exam administered at Prometric testing centers. It consists of:
8 blocks
60 minutes per block
40 questions per block (maximum)
Total testing time: ~9 hours (including breaks and tutorial time)
The exam covers a broad range of medical disciplines, including:
Internal Medicine
Surgery
Pediatrics
Obstetrics and Gynecology
Psychiatry
Public Health and Epidemiology
Each question presents a clinical vignette, often with lab values, imaging, and patient histories, requiring candidates to make a diagnosis, suggest treatment, or determine next steps in management.
Does the USMLE Step 2 CK score matter for residency match in the US as an IMG?
Yes, USMLE Step 2 CK matters significantly for your residency match in the US, especially as an International Medical Graduate (IMG) and further in this guide you will learn more why:
Step 2 CK is the Most Important USMLE Score for IMGs
Since Step 1 became pass/fail, USMLE step 2 CK is now the primary numerical score that residency programs use to compare applicants.
As an IMG, you compete with U.S. medical graduates (USMGs) who have built-in advantages (e.g., U.S. clinical experience, networking, and familiarity with the system). A high Step 2 CK score helps bridge this gap.
For highly competitive specialties (e.g., Dermatology, Surgery, Radiology, Neurology), a strong Step 2 CK score is critical.
Step 2 CK Helps Overcome IMG Disadvantages
IMGs often face visa restrictions, lower match rates, and limited access to some programs.
A high Step 2 CK score (250+) can make up for other weaknesses, such as:
A lower Step 1 performance
Attending a lower-tier medical school
IMG Rotations' Tip: Some programs use Step 2 CK as a “cutoff score” to filter applicants before reviewing applications.
Step 2 CK Predicts Clinical Readiness
Since Step 2 CK tests clinical knowledge and decision-making, program directors trust it as an indicator of your ability to handle residency.
A low Step 2 CK score might raise concerns about whether you can manage the workload of residency training in the U.S.
A score of 240+ is considered competitive, and 250+ is ideal for IMGs.
Step 2 CK Affects Interview Offers and Ranking
Residency programs prioritize candidates who are ready to start training without extra supervision.
A high Step 2 CK score can increase interview invitations.
Some programs use Step 2 CK scores when ranking applicants for the Match.
Some IMG-friendly programs require a Step 2 CK score before offering interviews.
Some States and Programs Require a Minimum Step 2 CK Score for IMGs
Certain states require a specific Step 2 CK score for medical licensure.
Some competitive programs have Step 2 CK cutoffs (e.g., 230-240+ required to apply).
IMG Rotations' Tip: Before applying, check program-specific score requirements on the FREIDA database or program websites.
USMLE Step 2 CK: Percentage Mark Allocation by Subject

Mock Exam to Score Correlation for USMLE Step 2 CK Prediction
One of the most common concerns for Step 2 CK test-takers is: "How accurately do mock exams predict my real score?" Fortunately, there are historical score correlations between popular mock exams and actual USMLE Step 2 CK scores. Below is a breakdown of how each practice test correlates with Step 2 CK performance.
NBME Self-Assessments: Most Predictive
The NBME (National Board of Medical Examiners) creates the actual USMLE questions, making their self-assessments the best predictors of your real Step 2 CK score.
NBME Score Correlation:
NBME Form | Correlation with Step 2 CK Score | Accuracy |
NBME 10, 11, 12, 13 | 0.85 – 0.90 correlation | Most predictive |
NBME Free 120 | ~0.75 correlation | Slightly lower predictive value but useful |
IMG Rotations' Tip: NBME scores are usually +/- 10 points of your real score if taken within 2-3 weeks of the exam.
UWorld Self-Assessments (UWSA): Slightly Overpredictive
UWorld Self-Assessments (UWSA 1 and 2) contain high-yield clinical vignettes that are more difficult but can slightly overestimate real scores.
UWSA Score Correlation:
UWSA Form | Correlation with Step 2 CK Score | Accuracy |
UWSA 1 | 0.75 – 0.80 correlation | Slightly overpredicts by ~5-10 points |
UWSA 2 | 0.80 – 0.85 correlation | More predictive than UWSA 1, but can still be ~5 points high |
IMG Rotations' Tip: If UWSA 2 is within 5-10 points of NBME, expect your real Step 2 CK score to be close.
AMBOSS Self-Assessment: Harder, Less Predictive
The AMBOSS Qbank and self-assessment questions are generally harder than real Step 2 CK, leading to lower scores.
AMBOSS Score Correlation:
AMBOSS Exam | Correlation with Step 2 CK Score | Accuracy |
AMBOSS Self-Assessment | 0.65 – 0.75 correlation | Underpredicts by ~10-15 points |
IMG Rotations' Tip: If you score lower on AMBOSS, don’t panic! Many students score higher on the real exam compared to AMBOSS self-assessments.
NBME Free 120: Useful but Not Highly Predictive
The NBME Free 120 is a free, official set of 120 questions, but it is not scaled like NBMEs or UWSAs.
NBME Free 120 Score Estimation:
% Correct on Free 120 | Predicted Step 2 CK Score |
85%+ | 260+ |
80-85% | 250-260 |
75-80% | 240-250 |
70-75% | 230-240 |
65-70% | 220-230 |
IMG Rotations' TiP: Use NBME Free 120 as a last-minute confidence booster, but don’t rely on it alone for score prediction.
How to use mock exams for the best score prediction?
Take NBME 10 or 11 → 6-8 weeks before the exam to gauge your baseline
Take UWSA 1 → 4-6 weeks before to assess improvements
Take NBME 12 or 13 → 3-4 weeks before to check progress
Take UWSA 2 → 1-2 weeks before for a final confidence boost
Take NBME Free 120 → 1-3 days before as a warm-up
IMG Rotations' takeaways:
If your NBME + UWSA 2 scores are consistent, expect your Step 2 CK score to be very close to them.
If your NBME is lower than UWSA, rely more on NBME for prediction.
If your AMBOSS is much lower, don’t worry, most students score higher on the real exam.
IMG Rotations' Pro Tip
NBME (Forms 10-13) = Most predictive (0.85 – 0.90 correlation)
UWSA 1 and 2 = Slightly overpredicts (~5-10 points high)
AMBOSS = Underpredicts (~10-15 points lower)
NBME Free 120 = Good warm-up, rough estimate based on % correct
