About Thornton Township High School District 205
Thornton Township High School District 205 divides grades 9–12 among Thornton Township High School in Harvey, Thornridge in Dolton, and Thornwood in South Holland. The boundary extends across all or portions of fifteen communities, including Blue Island, Burnham, Calumet City, Hazel Crest, Lansing, Riverdale, and Thornton. The property-level District 205 map determines the home campus.
International Baccalaureate is presented as a districtwide curriculum area, with current faculty listings at Thornton, Thornridge, and Thornwood; campus pages describe how individual schools implement the program. Outlook Academy uses another structure, offering flexible credit-recovery and graduation pathways for dropouts, non-graduating seniors, at-risk incoming seniors, and some juniors when space permits.
The Infant Care Center supports teen parents enrolled at any of the three home high schools. Licensed care is available for children from six weeks through age four, and specially equipped buses carry parent and child between the center and the student’s home school. The Adult Transition Program serves young adults ages 18–21 through employment readiness, independent living, community engagement, postsecondary planning, and self-advocacy.
