Argo Community High School is a public four-year high school located in Summit, Illinois, a western suburb of Chicago. The district draws students from the communities of Summit, Bedford Park, Bridgeview, Justice, Willow Springs, and a portion of Hickory Hills. The school was named for the area surrounding the large corn processing plant located near the school, which manufactured Argo corn starch and is currently owned by Ingredion. In 2014 and 2016, Argo was awarded a bronze medal by U.S. News & World Report for outstanding academic performance, the only school in the South Suburban Conference to receive such recognition.^[3]
