South Texas Junior College (STJC) was a junior college located in Houston, Texas (USA). The YMCA opened STJC in 1948 and operated the two-year coeducational liberal arts school; no tax money supported the school. The YMCA pioneered the concept of night school, providing educational opportunities for people with full-time employment. On August 6, 1974, the University of Houston acquired the assets of South Texas Junior College and opened the University of Houston–Downtown College as a four-year institution.
