I have referred to the NCAA rule books numerous times over the past few years and try to keep a good understanding of them. The rules around student-athletes' amateur status haven't changed much in that period. The key points covering the issues raised in this thread are:
- NCAA / NAIA / Juco have their own rules but their 'amateur' rules are all similar (all similar to the NCAA). For NAIA and Juco's players should read the rules or check with their coach;
- In NCAA D1 & D2, players will lose their amateur status if they are paid more than the prescribed expeneses - minor expenses related to travel, meals etc. If you are a college player, or intending to be one, then I recommend to not receive any payments whatsoever or be very carefull if you do;
- In NCAA D1 & D2, an unpaid student-athlete will lose their amateur status if they play on a 'professional' team. In the eyes of the NCAA, a 'professional' is any team with any player being paid above the prescribed expenses. In Victoria, a D2 student-athlete returning on College break would jeopardise their College if they played in SEABL and probably any BigV. They should stick with Youth League (or take a break!)
- Prospective NCAA D1 & D2 students, who have never enrolled in a full-time tertiary course, can play on a 'professional' team until they commence a full-time tertiary course. Students only become 'student-athletes' once they commence college and the rule above then applies;
- NCAA D1 student-athletes cannot play on their college break (unless it is for their college). No such restriction for D2 players.
Hopefully that sheds some clarity and helps prevent any mishaps. Maintaining a position on a college roster can be difficult if a (often new) coach wants a player off the roster to use the scholarship elsewhere. Unfortunately many coaches are ruthless and will use any excuse to withdraw a scholarship which means 'go home & no degree' for most student-athletes. I know of one such case atm, so players be careful, know the rules and dont give anyone an opportunity to end your college experience in a bad way.
