Northern Virginia Community College, often abbreviated NVCC and colloquially as NOVA, comprises several locations in the Northern Virginia suburbs of Washington, D.C., and is both the second largest multi-campus community college in the United States and the largest educational institution in the Commonwealth of Virginia. Since its establishment in Alexandria in 1965, NOVA has added a number of locations. Among these are the Annandale Campus; Manassas Campus; Woodbridge Campus; Loudoun Campus in (Sterling); a Medical Education Campus (in Springfield); an extension of the Alexandria Campus in Arlington, called the Arlington Center; and an extension of the Loudoun Campus in Reston, called the Reston Center. In 2003-2004, the college enrolled 63,000 students in credit courses and some 250,000 more in non-credit offerings. The student body is economically and ethnically diverse, and a very large number of enrollees are international students or immigrants. The school offers a wide variety of courses, and encourages students to enroll in four-year colleges after completing their NOVA education.
