Curriculum requirements for the four core areas are as follows: three-and-a-half years of mathematics, four years of English, four years of social studies (including geography, world events, economics, US government, world and US history courses), and three years of science. Students are required to take a year of physical education and a year of art (performance or visual). CHS offers courses in Spanish, German, and Anishinaabe. The College In The Schools (CITS) program allows students to take classes in high school, with teachers in the building, for credit through local colleges, notably Fond du Lac Tribal and Community College and the University of Minnesota Duluth. The colleges certify high school teachers and approve course curriculums, and students who take those courses receive a separate transcript from the college in addition to the normal high school transcript. Students also have the option of post secondary enrollment; for either senior or junior year (or both) they may enrol directly in a local college. They still graduate from CHS and can join sports and other extracurriculars at the high school, but attend all or part of their classes at the college.

Visual art classes are taught on drawing, painting, photography, sculpture and ceramics. There are three choirs: concert, crystal (all-women), and varsity (as well as a smaller group of madrigals who perform at sports games and other events throughout the year); a concert band, pep band, and jazz band; and an orchestra. There are also two theater performances every year, a musical in the fall and a play in the spring.
