The federal government offers a number of sources of revenue information through the U. S. Department of Education (which oversees NCES), and other sources. Each state has its own education department, which can provide information about state education funding. Because education is such a critical issue to so many people, elected officials are a good source of statistical information on school revenues. Local government sources and boards of education are useful resources for information about local funding. Most public libraries compile information about local school revenue issues as well.
