In 1969, Southdown High School (originally Houma Colored High School), which educated black students in Terrebonne Parish, was closed. Students were moved to Terrebonne High and South Terrebonne High School.

From 2015 to 2016, the Louisiana State Department of Education score for this school declined from 100.1 to 99.3; as an "A" level school makes 100 points or more, Terrebonne's rank fell from A to B.

In the fall of 2017, the 9th grade was scheduled to be moved from Houma Junior High School to Terrebonne High. In all other areas of Terrebonne Parish, 9th graders were already at the high school level. From February 2017 until the fall of 2017, existing 9th-grade students were reclassified as Terrebonne High students but continued to take classes in portable buildings at Houma Junior High.

Terrebonne High athletics competes in the LHSAA.
