I have seen sample CVs which state percentile result of step 1 and 2: e.g. Step 1 85th percentile. How is this percentile performance derived? Is it the two digit score?
 
The USMLE is like any other standardized test. Your percentile is derived from your score compared to everyone who takes the exam. For example, a score of 215 on step 1 of the USMLE means that you would fall in the 50th percentile, which makes that an average score. The nbme stopped submitting the percentile rank along with your 3 didit score to discourage residency programs from using it to weed people out based primarily on how well you did. They still give a 2 digit score but it does not correlate with your percentile rank. For example, if you score a 245 they will give you a 2 digit score of 99. However, your percentile would be in the low 90s. This makes the 2 digit score useless IMO because whether you 245 or 255 your 2 digit score will be 99. I know that all this is confusing but thats the way the show runs.
 
Thanks. Are you sure that only the two digit scores are reported to the residency programs.
 
From what I have learned, the only reason USMLE still gives a two digit score is that many states still have in their legislation that a minimum passing score of 75 is required for a medical license. The minimum passing score of 180-185 or whatever will always correspond to a 75. If all the States changed their legislation, I'd bet USMLE would drop reporting the two-digit score.

No. The program will get the 3 digit and 2 digit score. Based on your 3 digit score compared to the average, they can determine your percentile.
 
Its funny because many program directors still think the two digit score is percentile. Oh well, it makes us look better than we really are.

Another thing is I have no idea how the two-digit scores are calculated. I got the same two-digit score on Step I as Step II, yet on Step II my score was much higher when looking at the mean and standard deviation. Go figure....

say....... you scored 215 ( 3 digit ) on your step 1, will it be equal to 86 or 88 on the 2 digit score???😕
