Once you have registered for the ECFMG, you can register for your USMLEs. The USMLEs are comprised of four parts, Step 1, Step 2 CK (clinical knowledge), Step 2 CS (clinical skills), and Step 3. These tests will allow you to practice medicine in the United States, as well as help to shape your future as a Resident. Once you complete all parts, you will be ECFMG certified, and can apply to the National Residency Match Program, or NRPM.
Good things to remember are that although Step 1 is the first in the series of tests, however, if you choose to, you may take Step 1, CS or CK in any order. You can also take your Step 1s and Step 2 CK before you graduation from medical school. You do not have to take step 3 in order to apply for a residency, the Step 3 exam is often taken by residents in their first year. The Step 1 exam and Step 2 CK have test locations throughout the world, but Step 2 CS and Step 3 are only offered in the United States. It is also important to remember that you only have 7 years from the date you complete your first USMLE exam to finish the sequence of testing. If you prolong this, your test will not be valid and you will have to pay additional fees to retake this test.
