(October 2015) A state education agency (SEA), or state department of education, is a formal governmental label for the state-level government agencies within each U.S. state responsible for providing information, resources, and technical assistance on educational matters to schools and residents.
The Department of Education Organization Act divided the Department of Health, Education, and Welfare into the Department of Education and the Department of Health and Human Services. The Department of Education is administered by the United States Secretary of Education. It has approximately 4,400 employees and an annual budget of $68 billion (2016). The agency's official abbreviation is ED, because DOE instead refers to the United States Department of Energy.
