Alpha Sigma Tau (ΑΣΤ) is a national Panhellenic sorority founded on November 4, 1899 at Michigan State Normal College.
Alpha Sigma Tau is a member of the National Panhellenic Conference, an umbrella organization encompassing 26 national sororities or women’s fraternities, which focus on service, education, scholarship programming and social activities. Once a sorority exclusively for teacher's/educational colleges, Alpha Sigma Tau became a full member in 1951, and, as a social sorority, now admits members without limits based on major. It has more than 90 active chapters nationwide.
