In 1839 the Commonwealth of Virginia established the Virginia Military Institute as one of the nation's first state military colleges. VMI has remained financially supported by the state and subject to the control of the Virginia General Assembly. The school enrolls approximately 1,300 male cadets and offers academic programs in the liberal arts, sciences, and engineering that are also available at other Virginia public institutions. Its distinctive mission is to produce citizen-soldiers through an adversative method featuring physical rigor, mental stress, absolute equality of treatment, absence of privacy, minute regulation of behavior, and indoctrination in desirable values. Cadets live in spartan barracks, participate in drills, endure the rat line, and operate under a strict honor code. VMI graduates have included military generals, members of Congress, and business executives, and the school maintains the largest per-student endowment of any public undergraduate institution in the nation.
In 1990 a female high-school student filed a complaint with the Attorney General seeking admission to VMI. The United States then sued the Commonwealth of Virginia and VMI, alleging that the exclusively male admissions policy violated the Equal Protection Clause. Trial consumed six days and involved expert witnesses on each side. In the two years preceding the lawsuit VMI had received inquiries from 347 women but responded to none. The District Court ruled in VMI's favor in 1991, finding that single-gender education yields substantial benefits and that VMI's methods are inherently suited to men. The Court of Appeals for the Fourth Circuit reversed in 1992 and remanded the case for selection of a remedy.
On remand Virginia proposed the Virginia Women's Institute for Leadership, a four-year state-sponsored undergraduate program located at the private Mary Baldwin College and open initially to twenty-five to thirty students. VWIL would share VMI's mission of producing citizen-soldiers but would employ a cooperative method rather than an adversative one, would not require barracks living or uniforms during the school day, and would offer a narrower range of academic programs. The average combined SAT score of Mary Baldwin entrants was about 100 points lower than VMI's, its faculty held significantly fewer Ph.D.s and received lower salaries, and its endowment was substantially smaller. The District Court approved the VWIL plan in 1994, and the Fourth Circuit affirmed in 1995.
The United States petitioned for certiorari, which the Supreme Court granted in 1995. Some women could meet VMI's physical standards. VMI's methodology could be used to educate women. VWIL students would not experience the rigorous military training, faculty, facilities, alumni network, or prestige associated with VMI.
