The history of Mother Theodore Guerin High School (Mother Guerin) is found on the the Guerin
College Preparatory High School website address of http://www.guerinprep.org/about.html. In summary, Mother Theodore Guerin High School was established as an all-girls' high school in 1962 with 398 students enrolled
under the guidance of the Sisters of Providence, whose founder was Mother Guerin!
Of that initial enrollment total, 341 would receive their four-year diplomas in 1965. The peak enrollment in
school history would be 1,608 in the fall of 1976. From 1962 through 2004, Mother Guerin High School
graduated over 11,000 girls and prepared them "for college and life beyond".
Falling enrollment in its next-door neighbor and brother school, Holy Cross High School (for boys), led to the request by the Chicago Archdiocese for Mother Guerin to accept boys after the closure of Holy
Cross High School. This arrangement was set in place in after the 2003-04 school season. Beginning in the fall of
2004 Mother Theodore Guerin High School for girls became known as Guerin College Preparatory High School, a co-educational
Guerin Prep High School is located in the original Mother Guerin High School building.
