I absolutely agree with you, that Education is a state matter, however the OP was saying it was unconstitutional in a Federal Manner, IE seperation of church and state, which it has been shown by a PP that even the Supream Court disagreed that it is unconstitutional.
Also, If you wish to argue something violates a State Constitution, then you must amend your statment to refect your speaking of the state, otherwise the indication is the Federal Constitution.
On a side note, since it is a State Matter, can someone explain why we have a Federal Department of Education?
The right to an education is not in the constitution. However, it is in the constitution that Congress can tax and spend for the general welfare. So that is what they are doing with the Fed Dept of Ed. And with federal grants of money -Congress can attach conditions to the money.
is always billed as more important than school. And it's getting much more prevalent. I routinely have kids missing 1-2 weeks of school for vacations. It doesn't matter when the school vacation is or how long it is, parents will make their own plans. The ones that confuse me are the ones that will come back from the two-week winter break for a week or so and then be gone for another week or so to go skiing or to WDW or to wherever. The ones that make me frustrated are the ones that skip conferences to go on vacation since their kid will miss fewer days because of the schedule, but then they'll ask me to stay after school to have a special conference with them because they're the involved parents, after all. This is more of a problem with elementary and middle schools where the policy seems to be "you can miss as much school as you want and still be socially promoted." These kids have a very difficult time adjusting to high school.
The charter school gets to keep a semester's worth of state money for that student. The students also show up just in time to take the state tests in the assigned district.
