are public high school in austin tx for free or with fee? How much?

Free for both legals and illegals
However extra circular activities like sports have fees but if you're indigent or undocumented, there are grants

the fee is hidden in the taxes.....but the worst education is a public school, it comes out of your property taxes, forced compliance and no vouchers to use for pvt school......best bet is homeschool for an educated child of substance and not a public school victim of crummy schooling and bullying and politically correct stupidity......hope you figure it out.....
