For 33 years prior to 2006, most of the public high schools in the south and southwest suburban Chicago area were a part of the South Inter-Conference Association (SICA) which by 2005 had reached a membership of 33 schools split into five divisions.
[1] The conference covered a large geographic area and sociological spectrum "from the Indiana border to Joliet, from impoverished Ford Heights to affluent Frankfort, from virtually all-black Hillcrest to almost all-white Lincoln-Way Central and from Joliet, enrollment 4,993, to 1,066- student Rich South"[1] In 2004, the athletic directors voted 30–3, the principals' board of control voted 6–2, and the district superintendents voted 16–3 to approve a new conference realignment which was to take effect in 2006.
[1] The realignment had been pushed because of long travel times and a reduction of sports offerings at some schools.
[2] Shortly after the announcement, a board member from Lincoln-Way Community High School District, a district representing two of the schools leaving to form a new conference, was forced to resign after racially insensitive statements were left on a reporter's voice mail.
In April 2006, a federal civil rights lawsuit was filed against the schools which had left claiming that "(an) apartheid-like realignment used public funds to regress to separate but equal".
