As of the end of the 2007–08 school year, the past and present schools of the CSL have won 233 state titles in various IHSA sports and activities. They have finished in second place 261 times. Nearly half of these (105 state titles and 113 state runners-up) have been won by New Trier (or the two schools it was split into for a time, New Trier East and New Trier West). Evanston adds 47 state titles and 49 runner-up prizes. The league has remained stable (except for divisional realignment) since Niles North returned to the league in 1991.
