[2] Sullivan North's former facilities were designated by Kingsport City to be John Sevier Middle School's new campus [3] until 2022 when the facility became the Tribe Athletic Complex, which held middle school and youth league games and practices.

The Dobyns-Bennett basketball team had its season in the former Sullivan North gym due to roof problems with the Buck Van Huss dome.

Sullivan North used a modified block schedule with four 60- to 80-minute periods and one 45-minute class each day.

It offered several "accelerated", AP, and technical/vocational courses, including computer-aided design, carpentry, culinary arts, and criminal justice.

Sullivan North High School had athletics programs for basketball, baseball, cheerleading, cross country, football, golf, softball, tennis, track and field, volleyball, and marching band.
