We have several coops near me - one has over 1,200 kids (uses @ church facility) the other grew so large (over 3,000) it ended up becoming a private school/homeschool hybrid. It has a sports program that has 1,000s of kids (every sport you can imagine) as well.
I homeschooled my boys all the way through, we did a little of everything. It did and does bother me that I pay for a school system that I never used. But the thinking among most homeschoolers I know is if you get vouchers and tax breaks, you end up with the government having a say in what you teach, so everyone just stayed out of it.
I did participate in school board meetings though, and made my voice heard.
Not quite understanding what you’re saying about the vouchers or tax breaks.
Maybe my solution is too simple. The school system proposes a budget, right? City council or county commission approves it. Usually without asking a question about it. And we all pay for it regardless.
If the council/commission tells the school, you have 600 less students this year than you did last year, our math shows that you’ll be getting g this much less and the folks that have pulled their kids out will not be laying in, or, at least, not paying the full Monty like they have in years past.
Is that too simplistic?
