The Ortovox Safety Academy includes training courses on various mountain sports. The Safety Academy Lab Snow is all about avalanches. In partnership with various mountain schools, there are different courses on offer, from one-day basic courses for beginners to more extensive courses for advanced learners who want to gain more in-depth knowledge. (As the date situation is very uncertain this season due to Covid restrictions, interested parties should enquire directly with the mountain schools as to whether a specific date can take place.)
Much of the content is also summarized in an online booklet to read at home. Of course, this is no substitute for a course in the backcountry, but it's a good start for those who can't currently do a course and want to get into ski touring. And a good refresher for anyone who has been doing it for a while!
