How long is Step 2CK (how many questions)?
Similar to Step 1, examinees have 8 hours to complete seven question blocks – each block with no more than 40 questions.

What is a passing score for Step CK and how well have UM students generally performed?
Passing score for Step 2CK is 209, and UM students have scored in the vicinity of 240 (on average).

Are there any Medical School policies I should know about regarding Step 2CK?
You are required to complete 2CK by February 1st of year 4.  Since passing 2CK as a graduation requirement, this date allows students not passing the exam enough time to prepare for and re-take the exam.

What steps are needed to sit for the Step 2CK exam?

  • Students commonly begin the registration process at the end of year 3 between December and March (again, earlier for students thinking of seeking testing accommodations);
  • Start by going to your NBME account and paying your exam fee;
  • Similar to Step 1, choose a 3 month ‘eligibility window’ within which you plan to complete the exam;
  • No CIF is needed – your registration is posted for verification from the UM Medical School Registrar, Heather Peterson;
  • Permit to test – once ‘verified’ by the registrar, NBME sends out a testing permit for use in scheduling a test date via the Prometric testing centers.
