The average USMLE Step 3 score in 2026 is 227 with a standard deviation of 15. Scores roughly follow a bell curve — 68% of all Step 3 test-takers score between 212 and 242. The passing threshold is 200, which means nearly all adequately prepared candidates pass.
What is the median Step 3 score?
The median USMLE Step 3 score is approximately 227, nearly identical to the mean. This reflects the roughly symmetric distribution of Step 3 scores. Half of all test-takers score above 227 and half score below. For context, a score of 220 is well above passing (200) and sits near the 30th percentile.
Step 3 Score Percentiles
The following table summarizes the approximate Step 3 score percentiles based on USMLE data from 2022 to 2024. Use this to understand where a given score ranks relative to all examinees.
| Score | Approximate Percentile | Interpretation |
|---|---|---|
| 260 | ~97th | Top 3% of all test-takers |
| 250 | ~93rd | Top 7% |
| 240 | ~79th | Top 21% |
| 235 | ~68th | Above average |
| 227 | ~50th | Median (average) |
| 220 | ~30th | Below average, well above passing |
| 215 | ~19th | Bottom quintile |
| 200 | ~5th | Passing threshold (minimum to pass) |
How to Maximize Your Step 3 Score
To maximize your score and percentile on Step 3, you need to perform well on both the multiple choice questions and the CCS section. The CCS section accounts for roughly 25–30% of your total score and is the most improvable component — most candidates spend little time preparing for it, which is where points are most easily gained.
Use StudyCCS for CCS simulation practice and the SpeedOrders simulator to sharpen your order-entry speed and sequencing. Both are the highest-leverage activities for lifting your Step 3 score above the median.
