It's not a budget issue, I don't think. Most of the "southern" states use 3 man exclusively. I don't our school systems have anymore money than systems in northern states.
All varsity games are mandated by the NCHSAA to be officiated by a 3 person crew. Our local association uses 3 man crews for all JV games as well. How can you expect less experienced officials to learn the mechanics and move up if it's not offered to them?
However, we do some other things differently. We work a GV/BV doubleheader during regular season nights. I think other associations may work JVB/
VB or JVG/VG. We receive $75 for the doubleheader. I believe the fee goes up to $85 next year. You guys may receive more based on working a single game times 2. But it maybe a compromise you have to reach to get 3 man full time.
