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.
Major index to literature in education. Sponsored by the U.S. Department of Education, it provides full citations and abstracts for journal articles, books, curricula, government documents, dissertations, and research reports. ERIC citations date from 1966 to the present, and full text is available for many research reports.
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.
