Cook County was established in 1919 from a part of Berrien County. On February 4th of the same year, the first meeting of the Cook County Board of Education was held. At that time Sparks and Adel both were independent school systems. The only high schools then were in Sparks and Adel. The Cook County school board paid the Adel school system for "country children coming to school in town."

On March 8, 1927, Adel and Sparks voted out the independent school systems and became the Sparks-Adel Consolidated School District. Sparks-Adel High School opened on February 20, 1928. It offered grades 8-11 for nine months of the school year.

In 1928 the Adel Colored School, which had been in existence before the formation of Cook County, was officially called the Adel High and Industrial School. One year later its name was changed to Sparks-Adel High and Industrial School. It offered classes in grades 1-11. In 1937 its name was again changed, this time to Cook County Training School. Finally, in 1969, the name was changed to Cook County High and Elementary School.

Sparks-Adel High School became Cook County High School on April 20, 1949. Thirty-four days later it was changed to Cook High School. There have been renovations and additions, yet the site and the name have remained the same since.
Starting in the 1952-1953 school year, both schools opted for completion of the 12th grade for graduation. 1965 was the first year of partial integration with 8 black students opting to attend Cook High School and Cook County's freedom of choice. A year later two black teachers were employed at Cook High School.

The first elected board of education for Cook County met on January 7, 1969. The beginning of the 1970 school term marked the end of segregation in public schools in Cook County. Cook High School become the only public school in the county which housed grades 9-12. Cook County Training Center became Cook Junior High School and then Cook Middle School.

Cook High School moved into its current, state of the art campus on Highway 37 in the fall of 2009.
