Waivers are required paperwork in order to play in most sports. Make a signed agreement for conduct, interaction and reporting rules as well. If, for example, an underage athlete is texting, communicating or meeting with the coach after hours or out of program, require that it be reported and immediately follow up on those reports to correct potentially problematic behaviors before an issue arises. When you make enforcing the rules everyone’s job, you protect the mission, the coach and the athlete.
