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, Robotics, 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.  Graduates who wish to pursue their musical careers beyond high school are highly sought by colleges and universities.

The vocal music program 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 benefited from visits by individuals and groups representing the choir.  Many former choir members have received scholarships to continue their vocal studies, and local churches reap the benefit of these trained voices in their church choirs and youth groups.

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.  Current plans include revitalizing the competitive portions of the ROTC, including those involving military precision drills, rifles, sabres, and color guards.

The Robotics team has earned local, state, and national accolades as it has represented CHS and Louisiana at national and world competitions.  Further information about this organization can be found by visiting the Science Department's page.
