Students at Carroll High School may participate in a variety of activities. Co-curricular opportunities include the Carroll High School Marching Sound Machine Band, Vocal Ensemble, and Air Force Jr. ROTC. Each of these groups has performed locally, statewide, and even nationally.
The band participates in many battles of the bands and hosts its own well-attended event every fall; it has performed at the Rose Bowl Parade, numerous Mardi Gras parades, Black History parades, and others. Currently, it is working to raise money to travel to Washington, D.C. to perform. Graduates who wish to pursue their musical careers beyond high school are highly sought by colleges and universities.
The choir also has a well-chronicled history of success, competing in Georgia and Texas, performing in Washington, D.C. and at Carnegie Hall in New York, and being invited to perform in London. Locally, there are few churches that have not invited the choir to perform, and nursing homes have benefitted from visits by individuals and groups representing the choir. Many former choir members have received scholarships to continue their vocal studies.
The Air Force Jr. ROTC has provided a Color Guard for numerous civic events throughout northeast Louisiana. It has marched in parades, performed at local churches, and opened numerous festivities. Several graduates have received scholarships because of their participation in the AFJROTC with the most notable being Mike Davis who received a full scholarship to West Point as a result of his academic record and his skills learned in the program.
