National Honor Society (NHS) members must show exceptional accomplishment in Scholarship, Leadership, Character, and Service. At Cook County High School, Scholarship eligibility is determined by GPA: 3.8 for sophomores, 3.7 for juniors, and 3.6 for seniors. GPA alone does not automatically get an individual into the NHS. Leadership, Character, and Service eligibility is indicated by outstanding accomplishments in the school and community. In order to be considered for membership in a local NHS chapter, a student must also have been enrolled in that school for at least one full year. Each spring since 1961, CCHS has added a few exceptional students to its NHS chapter. The NHS Selection Committee reviews applications and determines who makes the NHS.
