Since Step 1 went pass/fail in January 2022, Step 2 CK became the single number residency programs use to compare applicants. A 2024 NRMP program-director survey found it the 4th most frequently considered factor in interview decisions — and 30% of programs require a target Step 2 CK score just to get an interview. This site is an unofficial, educational reference on the exam: the national norms, why programs weight it, and how to think about preparing.

Why Step 2 CK carries so much weight
Step 1 used to be the great sorting exam of medical school. When it became pass/fail in January 2022, nothing replaced its role — the sorting simply moved. Step 2 CK, which tests clinical knowledge and reasoning across the core clerkship domains, is now the only scored exam whose result arrives before residency applications for most students, and program directors have noticed: in the 2024 NRMP Program Director Survey, the Step 2 CK score ranked as the 4th most frequently considered factor when deciding whom to interview, and 30% of programs required MD applicants to reach a target Step 2 CK score to earn an interview (2024 NRMP Program Director Survey, via AMA reporting).
The stakes are visible in the national numbers. First-time pass rates are high — 98% for US MD students (2022–2024 cycles) and 96% for US DO students — but passing is only the floor. The mean score was 249 in 2023–24, and the passing standard was raised to 218 in July 2025 (source: USMLE Performance Data via NBME, as summarized in AMA reporting; authoritative tables at usmle.org → Performance Data). Failing carries real weight: the same 2024 NRMP survey found 77% of program directors consider failed Step attempts when deciding whom to interview. And repeat-taker pass rates fall sharply — roughly 74% for MD and 72% for DO repeat takers — so a first-attempt pass is genuinely a career variable, not just a school metric.

The 2024 NRMP Program Director Survey (reported via the AMA) put hard numbers on something students already sensed: with Step 1 pass/fail, programs leaned harder on Step 2 CK. Beyond the headline figures — 4th most considered factor, 30% with target-score thresholds, 77% weighing failed attempts — the pattern is consistent across specialties: the score is used as an interview filter first and a ranking input second.
That doesn't make Step 2 CK the whole application. Program directors consider many factors — clerkship grades, letters of recommendation, MSPE narratives, research, and demonstrated fit all appear on the same surveys. But the score is the one national, standardized number that travels with every application, which is exactly why it's worth understanding early. The Match Data page shows what scores meant for 2024 seniors across representative specialties — observed data, with the caveats stated plainly.
