First of all, it's about time Vanderbilt got a new track.
Second, Level I is a truly introductory course. No experience necessary - the class I went to had high school teachers learning to coach track for the first time, new college assistant coaches, and club coaches. You take the class, and there's a written "take home" test that you take and send in on your own schedule.
Some time was spent on how to deal with coaching kids, not going overboard on the whole coaching thing, not screwing them up. Teaching events from scratch to people who'd never done them. Almost all the events were covered in brief. I went with a buddy who was a sprints/field events, and between the two of us (I'm a distance guy), we both learned something we didn't know in at least some of the lectures.
You have to take Level I to go on to Level II (more advanced) and beyond.
It depends on the area you live in - some places you're lucky if they're once a year. The one I took was in Wisconsin, and there was one guy from Tennessee there.
