What is the last date to take Step 2 CK in order to get ECFMG certificate 1 Sept? (Assume that the other Steps are taken)
How important is it to be ECFMG certified on this date in order to match?
How important is it to have your Step 2 CK result by 1 Sept in order to match?
This is actually a difficult question to answer.
The importance of when ECFMG certification is completed varies from program to program. I've seen some programs list deadlines on their websites for when applicants must have this done and some don't even mention it. Some only list deadlines for when applicants should have Step 1, Step 2CK, and Step 2CS done.
I think it's far more important to just simply take the exam and have it passed by September 15th (
which is the new date the applications will go out as of the 2012-2013 cycle; it changed from September 1st). Programs will have access to your USMLE scores and most will understand that if you've passed those Step exams, then it's just a matter of time before your ECFMG certificate is issued.
It will serve you well to have passing scores on all three of those exams by September 15th. But at the same time, you shouldn't rush yourself if you're not fully prepared. Taking the exam early and failing it is far more catastrophic than taking the exam in the fall and passing it. If you really want to have the result by September 15th, then you'd have to take the exam by Tuesday, August 21st. And who really knows... what if there is a delay in score reporting that week? It's impossible to answer 100%, but that is the most likely scenario.
Do you already have your medical diploma from your medical school? Some schools require Step 1, Step 2CK, and Step 2CS to be completed in order to graduate and some don't. It's very difficult to say when your certificate would be finished without knowing this. And if you go to a foreign school that doesn't often work with the ECFMG, then perhaps things could be delayed even longer.
I can tell you one thing, it usually takes 3-4 weeks to get the USMLE Step 2CK result from the day you take the exam, which is the 4th Wednesday after your exam date. But then you have to go through the remainder of the ECFMG certification process, which could take a few weeks, depending on if your school is waiting on your scores to release your diploma.
Maybe these websites can help you find more details on when exactly your ECFMG Certificate would be issued... I'm not sure anyone can answer that question without knowing further details of your situation. See if you can find that at one of these websites:
