How does public education showcase the complexity of federalism

Public education showcases the complexity of federalism because there is a strong debate about whether public education should be more centralized, or more federalized.

Because public education, as the name implies, is a public services, the central government feels that it should set common standards for every school in the country. These common standards are what is known as common core.

On the other hand, some states feel that the common core is an aggression against their rights as states. They feel that public education should be left to the states, and that each state should establish their own educational policies. This is a federalist position because it tries to strengthen state power over central government power.
