i heard dome rumors about it. is it true?
does it have any implications, such as putting greater emphasis on step1 or on the cs part?
False rumor.
Let's address step 1 first. This is the test that is more being debated to become a pass / fail, but I personally don't think it will happen. Statistics have shown, in addition to opinions from a number of PDs, that step 2 CK is more important than step 1. Also, step 1 tests knowledge that most practicing physicians do not use, when compared to step 2 or even step 3. However, step 1 is the only standardized exam that can compare applicants across the board, since it IS required to apply to a US residency.... step 2 CK is not.
Step 2 CK is evolving to incorporate more of the basic sciences. This is evidenced by the NBME adding more basic science questions to the 2009 USMLE changes.
Step 2 CS is also of much debate because it costs so much money and I've heard other PDs at the conferences say that CS is a waste of money, time, and effort. However, other PDs have said that the patient encounter is dying and that some standardized way should be implemented / tested. Keep in mind that these days, orders can be done on a computer miles away without even seeing a patient.
No talks currently for step 3.
The current talk right now is to combine step 1 and 2 CK into one big exam. This would be a monster of an exam, and I'm personally voting against it.
Again, none of this is likely to happen soon or radically.
