St. Catherine's High School is a private, Roman Catholic high school in Racine, Wisconsin. It is a member of Siena Catholic Schools of Racine and the Catholic Schools of the Roman Catholic Archdiocese of Milwaukee.

History

St. Catherine's traces its origins to the fall of 1864 when the Racine Dominican Sisters established an all-girls' day and boarding academy. In the fall of 1864, the Racine Dominican Sisters opened a day and boarding school for girls on property they purchased at Twelfth Street and Park Avenue. The school was named St. Catherine's Academy. In 1874, the Academy was chartered by the State of Wisconsin, with the power to confer academic honors.

In 1907, the facilities of the Park Avenue building were no longer able to accommodate all the young ladies who made application for study there. Accordingly, the Sisters erected a boarding school, known as Holy Rosary Academy at Corliss, (Sturtevant), Wisconsin; day students continued to attend St. Catherine's Academy. Holy Rosary was closed in 1917.

In 1924 St. Catherine's (coed) High School opened and the all-girl academy was closed. A statue of St. Thomas Aquinas, the great Dominican saint and scholar, was enshrined in a niche above the main entrance, for the institution was originally to be named in his honor (to be known as St. Thomas High School.) The academy girls, however, convinced authorities to retain the name of St. Catherine's.

In the fall of 1945, in order to accommodate all the students seeking admission, St. Catherine's inaugurated a double-shift schedule. Excavation for a new wing was begun in March 1947, and Archbishop Kiley of Milwaukee dedicated the building extending 175 feet south on Park Avenue in August 1949.

The lot on the east side of Park Avenue is now used as an athletic field by the school. It was given to the school to use when the Dominican Sisters built their new motherhouse, Siena Center, and had the old convent building which stood on that property demolished. The North Central Association has accredited St. Catherine's High School since 1937.

On August 1, 2018, St. Catherine's became part of the newly-founded Siena Catholic Schools in Racine operated under the Archdiocese of Milwaukee, and is no longer a sponsored ministry of the Racine Dominicans. However, a member of the Racine Dominicans will sit on the Board of Trustees for the indefinite future.
