According to the United State’s four page, 1789 Constitution there is NO mention of federal regulation of education. It wasn’t until 1791 that the Tenth Amendment was passed and states assumed responsibility of public education.
This explains why schools began on such a small level, because they weren’t required by U.S. law and they weren’t yet set up. It wasn’t until parents gathered their children together and hired a tutor that kids began to learn in a more traditional setting. However, it was not as in depth as today’s schools by providing all different classes to take. Most students were only taught reading and the Bible from their tutors.
