In our standard format, we'll list some helpful steps to aid the coach or athletic director in storing, collecting, and inventorying equipment. Every school treats the handing out of athletic equipment differently. Personally, I have never been one to issue equipment to athletes at any level. Schools which choose to do so run the risk of losing it. I do issue practice gear.
Uniforms are another matter entirely.
With practice stuff, record numbers and sizes for both shirts and pants. A surefire technique to facilitate proper equipment management is to order practice gear that coordinates with uniforms, number-wise. That practice will save you a lot of time. When I begin working for a school system, the very first basketball thing I do is check the uniforms. I find out what we need, and I make sure we have a trunk to keep the uniforms and warm-ups in during the course of the season.
