[6] Before 2020, when Gallatin High School opened, enrollment was roughly 1,800 per year.

[7] Students were few, and due to dropouts, the high school did not graduate its first class until 1882.

The portion of the building previously used for the old middle school was remodeled slightly with a new cafeteria and main offices and library, now called north campus, or "N Wing" to students.

[10] It also offers Advanced Placement courses in American history, art, biology, calculus, chemistry, English literature and composition, European history, French, German, human geography, government, microeconomics, music theory, physics, psychology, Spanish, statistics, and world history.

The campus has a 10-lane all-weather running track for use in the health enhancement curriculum as well as in extracurricular activities.

Athletic programs include Cross country, track, softball, cheerleading, football, basketball, volleyball, swimming, wrestling, soccer, and dance.
