I think $100 per player per sport is fair. As a parent with kids in band and athletics...let me say as a band parent I have paid more for band than athletics.
We put out 400-600 a year per kid, and that does not include their spring trip. For that money my kids are fed and have a snack and drink at each football game, get marching shoes and other uniform items, cover the cost of the color guard instructors that the school district will not pay for, and it covers the uniform cleaning costs.
For athletics, I did not have any set fees. I did have to purchase a hat and shirts for practice, and of course all his equipment, bat, gloves, cleats etc for baseball. For my other daughter who was in volleyball, softball, basketball, track and powerlifting during her 4 years...again my only cost was for her personal equipment.
In all areas there are fundraising. As parents we work at the professional ball park, football stadium and at the Speedway to earn funds for the band or we sold stiff, the kids wash cars and we have an all school garage sale. And for those who can not afford to pay as boosters we scholarship a lot and when that student turns 16 we expect that they work with us at our fundraising venues. For baseball, we host local tournaments for our teams and over the summer partner with the area youth ballparks and rent our field out for 14 and above tournaments.
But for a public scool to require that amount of money, 1000+ just to play ball well I would be playing select or travel ball. Now if that 1000 covers the trip then that is something as parents that should be discussed and agreed upon as a team, and again I would expect that the boys on the team get up and work/fundraise. There are many opportunities for them to earn money, have a neighborhood event when the boys mow lawns or fix fences and pull weeds. Host a hitathon or a long ball contest. Have a community movie night in the outfield and maybe have a small Camp where the players help teach younger ones some basic baseball skills
I guess my pointerest is, there are ways to fund a program without draining the parents dry, but I also do feel as parents we should have to pay some kind d of a fee because let's face it, the money has to come from somewhere and we send our kids to school to get an education first. Sports and athletics are important, but should come 2nd to education.
For anyone wondering, I am in Texas.
