Trinity Washington University, founded in 1897 by the Sisters of Notre Dame de Namur, is a Roman Catholic university located in Washington, D.C. across from Catholic University of America and the Dominican House of Studies. Although it has been a university since September 10, 2004, Trinity's College of Arts & Sciences undergraduate program maintains its original status as a liberal arts women's college. Men are accepted into the School of Education and the School of Professional Studies at both the undergraduate and graduate levels. Trinity College was founded by the Sisters of Notre Dame de Namur in 1897 as a Catholic college for women. For over 70 years, Trinity educated middle-class Catholic women, who were underrepresented in America's colleges. (For more background on women's higher education, see Origins and types of Women's colleges in the United States.) In the 1960s, the school vied with Wellesley and Bryn Mawr for the daughters of the wealthy and powerful. But when many all-male colleges became co-ed, Trinity's full-time enrollment dropped - from 1,000 in 1969 to 300 in 1989.
