When I affiliated my club Uspsa sent me a new shooter DVD , curriculum, and "Practical Shooting safety check" cards to give out.
many clubs have some form of new shooter training. Some better than others. Some clubs are restricted in facilities that they would have issues complying with classes on off match days. Most clubs are low on volunteers to do such a thing. Making this compulsary may have some damaging unintended consequences for clubs who are unable to comply.
It is a great idea. I used to teach such a class years ago, 2004-2007. It was 4 hours long and the students shot 100-150 rounda, sometimes more. I loved doing it, but it is a difficult thing for me to do these days due to getting access to facilities.
