Please read all the pages on the course website carefully before registering for the course. If the website seems too complicated or otherwise difficult to follow, then you should take an avalanche course from a different provider.
You can read about the course in this article (on p. 25) published by the American Avalanche Association's The Avalanche Review. (The course was also the subject of a presentation at the November 2011 first annual Eastern Snow and Avalanche Workshop.)
For additional training that complements an avalanche course, here is an example of an introductory-level NSP Mountain Travel and Rescue course. And here is an example of an integrated Level 2 course for Avalanche and Mountain Travel/Rescue.
