Via a piece at Protein of the above title:
The Tenth Amendment to the Constitution reserves to the states all powers not delegated to the federal government. For most of our nation’s history, education was considered preeminent among those reserved powers, and for good reason. Teaching and learning are quintessentially local activities—the thought never would have occurred to our founders that a bureaucrat in Washington is more capable than parents or teachers of creating an educational plan appropriate for an individual child.
I heartily agree with the whole thing.
