CY instructor

I'm seriously considering enrolling in the Knitting Certification courses, and would like to know what they will involve.
I have, in the past, taught beginner's knitting classes for JoAnn's, and at the local public library.
How many lessons are there, in each section, how many classes are in Knitting 1 and 2? Will I be mailing swatches of pattens they ask me to make, and will I need to become a part of Michael's, in order to be certified? Or, may I complete the course, and strike out on my own?
