This U.S. Government published manual compiles the state education laws of the day. It notes:

“Each of the 48 States has its own distinct system of education.The Federal Government assumes no control over the public schoolsthroughout the country except with reference to the special. Federalappropriations for specific purposes, as the Smith-HughesAct forassistance to vocational education and the Smith-LeverAct for assistance to agricultural extension education. Nevertheless, because of proximity and interchange of ideas, the State systems have many points of similarity. Conditions affecting the kinds of school systemsdo not differ fundamentally; therefore, each State profits by the experiences of others.”

The manual also has data on the race of pupils being taught, teacher salaries, who serves on education boards, and more.
