But it isn't. The charter schools can and do kick out kids. In fact, a common tactic we hear often about is charter schools taking in X kids, then taking in Y dollars per kid (X). But then, mid-way through the year, after all the checks have gone through, they kick kids out due to low performance or "because we don't have the means to handle children with mental disabilities", but do they give the money back? No. They keep it.

So the kid is now back in public school, but the money for them isn't there, it's in the charter school.
