Since all of the Instructor specialty courses are always scheduled after the IE, I am guessing that it is a prerequisite to pass the IE first. It would make sense, but I found out yesterday that there will not be an IE where I had planned to go through the IDC which is scheduled to start tomorrow. That changes the dynamic for me trying to obtain certain specialties. I am sure with some research that I can find this information on my own, but sometimes this can be a quicker way to obtain info. Thanks.
