jargon124,
You're totally correct. The major specialties do use your USMLE scores. However, these scores aren't used in raking an applicant usually. The scores are merely a weed-out mechanism. Programs usually have a cut-off number. Everyone below that cut-off score gets an immeadiate reject.This allows porgrams to cut their applicant pool by almost half. Next, third year grades, letters of rec, dean's letter comments, and research decides on which applicants will receive interviews. The interview is a major player on ranking. The program assess whether you'll be a good fit into their program. Specialties usually take a very low number of applicants. so personality plays a big role during the interview process. And remember, there's a;ways the "WHO YOU KNOW" factor.
In Short, USMLE scores, esp. STEP 1, plays a critical role in receiving consideration from specilaty programs. Traditionally, low scores equal low number of interviews. However, there are exceptions to every rule. The lower the USMLE score, is an indication to applying to a high number of programs. Although, there are always exceptions to every rule.
GOD Bless.
