James Madison High School serves students in grades 9-12. Originally named Forest Avenue High School, the school's name and official colors, emblem, and mascot were changed in 1956 at the request of the parents' association and students after the district decided to re-designate the institution as a "Negro school" (the district had not yet agreed to begin desegregation as specified by the Brown v. Board of Education decision).
