The school colors are old gold and royal blue. The average annual enrollment is approximately 1,800 students. Miami Northwestern was founded in 1955 to serve the increasing population of northern Miami. Shortly after the school's inception, the Bull was chosen as the official school mascot from the former Dorsey High School. Miami Northwestern originally served as an all-black high school. Beginning in 1966, Dade County high schools stopped being segregated, and most students from Booker T. Washington transferred to Northwestern in 1967–1968.
