Public schools in the United States are organized into districts, which are overseen by state and federal agencies. Here are some ideas of places to search.
For all education-related topics, you should also search the ERIC database (linked below), which will connect you with a wealth of education-related scholarship.
Like Gustavus, most colleges & universities will have a wealth of information available online. You'll need to do some digging, but here are examples of information sources at Gustavus. You will find most (if not all) of the same kinds of organizations and structures at other institutions. I've listed examples of college publications (newspaper, yearbook, alumni magazine) and relevant campus offices.
