The Irwin County High School marching band attended and played at the 2011 Sugar Bowl in New Orleans.

65% of students at ICHS were white/Caucasian, 31% were African-American, 0.02% were Asian, 0% were Hawaiian/Pacific Islander, 3% were Hispanic, and 1% were two or more races.

Around 2000, due to an increase in the student body, a need for additional classrooms was identified.

Irwin County High School follows the national CORE curriculum set of standards.

It also offers business education, Spanish, library sciences, journalism, and show choir courses.
