The City of Manassas is served by the Manassas City Public Schools. There are five elementary schools in Manassas, one intermediate school, one middle school, and one high schools. In 2006, Mayfield Intermediate School opened, serving students in fifth and sixth grade. Some schools in the Prince William County Public Schools district have Manassas addresses; they serve areas outside of the Manassas city limits and are located outside of the Manassas city limits. Also in the vicinity of Manassas are branch campuses of American Public University System, George Mason University, Northern Virginia Community College, ECPI College of Technology and Strayer University. Despite that some of these may in fact be just outside the city limits in Prince William County, NVCC and Strayer call these branches their “Manassas Campuses.”
