Four schools would be added for the 2000 school year and the league would be broken into 2 divisions. The existing schools; Antioch, Lake Forest, Libertyville, Mundelein, Stevenson and Warren formed the Lake Division and new comers; Grant, Round Lake, Vernon Hills, and Wauconda would join existing members North Chicago and Zion-Benton in the Prairie Division. The primary criteria for the separate divisions is school size, with the schools in the Lake Division being larger than the schools in the Prairie Division. In 2005, Lake Zurich joined the Lake Division and Lakes High School would be placed in the Prairie Division. Additionally, Antioch and Zion-Benton would switch divisions. Changes Beginning with the 2016-17 athletic season, the NSC reduced its size as the members of the Prairie Division elected to leave the conference to form the Northern Lake County Conference. This conference consists of Antioch, Lakes, Grayslake Central, Grayslake North, Waucounda, Round Lake, Grant, and North Chicago. Vernon Hills also left the conference to join the Central Suburban League. The new NSC also welcomed Waukegan during the 2016-17 season.
