And it's not just education. Pretty much all interaction between state and federal government is of that sort now. The states, intended by the Framers to be the principal governmental entity, are now essentially just administrative units of the federal government.
Another example is the drinking age. It became almost universally 21 because the feds threatened to cut off highway funds to states that failed to conform to their standard. I know for a while Louisiana was a holdout, but I'm not sure if that is the case any more. Leviathan will brook no non-conformity.
