All of the requirements are on the Federation website (link on the previous post).

Do a search on the FFF website for CI's or MI's for your state or region and find a coach. This can help immensely. Remember the test is not just about casting; but, about teaching. Many folks miss this distinction and can cast terrific; but, can't teach!

It took me 2 tries; but, well worth the effort since the process enabled me to develop into a better instructor. Go for it!
