The view of the liberals and progressives is that the education of children is simply too important to be left to parents or the states. So the liberals have been trying for years to impose national content standards on the schools, and to achieve this they tie those demands to grants of federal money. The liberal agenda is to intercept parents' rights to transmit their values to their children by changing the kids' values while they are in school.
The current version of this push is called Common Core Standards. It has started with standards for English language arts and mathematics, and national standards for science, history and other subjects are already on the drawing board. The experts have also been building a computer file of personal information on all students, from preschool to high school, and trying to maintain it through college and into the workforce. The schools are demanding access to all kinds of personal data, and also the right to exchange that data with other government agencies.
It surely would never have occurred to our Founding Fathers that some bureaucrats in Washington were more capable than parents in creating educational curriculum for children.
