As far and I can tell, USAC renamed the beginner categories for men and women to novice. I checked some race registration pages and there is men's novice racing. I did not see any masters novice racing combined with higher categories. For example, there was an entry possibility for master 50+ novice but no masters 3/4 novice and etc.
