Rosary High School is a Catholic college preparatory high school for young women sponsored by the Dominican Sisters of Springfield, Illinois. At Rosary, we encourage young women to achieve their greatest potential. Since 1962, Rosary has maintained a reputation for providing a rigorous college preparatory education. Rosary's small size, nurturing spirit, family atmosphere and dedication to excellence in single-gender education make Rosary the right choice for educating the young women leaders of tomorrow.
