It just makes sense for a new Archery Hunter to get lessons from someone who is, fully, qualified to give proper instruction. The same goes for MR and ML. To make it mandatory is not a good idea.
I went to the Nortwest Archery Club for professional lessons and was told to keep practicing what I was taught. I am glad I did. Now I feel confident in my bow and have no second thoughts about my release.
Also, the tips from this forum give me a wealth of information I can use when I go to Europe and start Bow Hunting there. BTW, you have to pass an archery class there, as well, but the restrictions, evdn a novice like myself, can laugh at. 3 arrows in a 6" bull and 30 yards.
