STAC is a coeducational, independent, nonprofit institution of higher education founded by the Dominican Sisters of Sparkill, whose values and spirit continue to pervade the campus. Occupying a bucolic 60-acre campus in the historic Hudson Valley of New York, the College has the advantage of being located in close proximity to New York City and the major metropolitan area of northern New Jersey. The College serves both undergraduates and graduate students and offers a values-based education in the liberal arts and sciences, business, and education.

The institution attracts a diverse student body (57% Caucasian, 19% Latinx, 9% African-American, 4% Asian-American); one-quarter of the student population is Pell eligible. Three-quarters of the students come from New York State. STAC has a robust dual enrollment program with local high schools and has close to 900 students enrolling in these programs each semester. Students of all backgrounds are attracted to STAC, including recent high school graduates and returning adult students, working professionals, and veterans of the armed services. First-year to second-year retention in fall 2018 was 81%, and the 6-year graduation rate of the 2012 cohort was 53%.

Approximately 45% of students live in college-owned, operated, or affiliated housing.
