Hi
I own an IDC center and i have seen both sides, people that come to me to do an IDC that have worked as a divemaster for a long time and not bothered to keep up with their theoretical work and have to re learn it all, the IDC teaches you how to teach, it is very important to keep up with changing standards and your theory.
I have had people that do their IDC straight after their divemaster in this case they are usually 'up to speed' on all their theory and standards.
I think it can be done both ways but do please keep up to date, it will make your life much easier for the IDC, if you can arrive with good theory and skill demonstrations your IDC will be so relaxed.
