Members
The Independent School League (ISL) is an athletic league comprising nine private secondary schools in the Chicago metro area. All of the schools are also full members of the Illinois High School Association, the governing body for most high school athletics and competitive activities in the state. The schools are all relatively small, most belonging to the smaller classes of competition offered by the IHSA.
