Thornton Fractional Township South High School (TF South, TFS) is a high school located in Suburban Cook County, Illinois, located 6miles from the city limits of Chicago. The school serves an area of approximately 9sqmi, & serves around 2,000 students in grades 9-12 who reside in the near South Suburban communities of Lansing and Lynwood.
Thornton Fractional South High School opened in 1958[10] and Thornton Fractional High School in Calumet City, which opened in 1926, was renamed to Thornton Fractional North High School. The school flag, a replica of the flag of the Confederacy of the United States,[11] was retired in 1993.[12] The associated Rebel mascot name was later retired in 2020,[13] and replaced with the Red Wolves in 2022.[14] The Thornton Fractional Vocational Center, later renamed the Center for Academics and Technology was later built between the two high schools in Calumet City and opened for T.F. South and T.F. North students and has served many purposes, from being a freshman academy, to hosting AP courses for students from both campuses, to housing programs such as CAD, nursing, and culinary arts.
In 2010, District 215, T.F. South, T.F. North, and CAT, combined had an average composite ACT score of 18.7. Also in 2010, the total enrollment at T.F. South was 2,014 and graduated 93% of its senior class.[15] T.F. South has not made Adequate Yearly Progress (AYP) on the Prairie State Achievement Examination, PSAE, a state test used in Illinois to fulfill the mandates of the federal No Child Left Behind Act. When comparing District 215's 2008–2009's PSAE scores to 2009–2010's scores, the scores have significantly gone down. Overall, the school has not met minimum expectations in neither mathematics and science. All three of the school's student subgroups failed to meet expectations in mathematics, and two of the three failed to meet expectations in reading.[4]
T.F. South competes as a member of the South Suburban Conference. The school is a member of the Illinois High School Association (IHSA), which governs most athletics and competitive activities in Illinois. Teams are known as the Red Wolves. The teams were formerly known as the Rebels before changing their name to the Red Wolves in 2022.[16] The Athletics Director is Marc Brewe.[17]
