I thought we could not talk about things that have a regional answer?
The best way I can tell you is it varies so much, there are no set fees.
I have been paid for a single 3 Person game as low as $45 to $60. It depends on the conference you are working. There are no across the board fees unless you are working the playoffs.
I cannot tell you what takes place at the JV level, I do not work enough of those games to have a read on those fees. I just know those are almost always 2 Person and they do not get paid as much as the varsity officials.
Peace
