Until the 1960s, the school system, like many others in the United States, segregated schools by race, with white students attending one set of schools and non-white students attending another.
The district was fully racially integrated in 1968. Elementary schools began to be integrated before 1965. In 1965, students from non-white schools were allowed to apply to attend Huntsville High School instead of the non-white high school, Samuel W. Houston High School. One of the first African-American students to attend Huntsville High School was Joreen Kelly. She later became a teacher at Huntsville High School.
