Opelousas Catholic offers a range of extracurricular activities designed to meet to  the interests and needs of the student body. Each student is encouraged to participate in these activities for his/her own enjoyment and development.

Organizations and clubs include participation in academic fairs, rallies & conventions, community service projects, and school spirit. The school encourages its students to participate outside of the classroom. To become a member of any organization, a student must contact the sponsor of that group. It is a privilege and requires the maintenance of acceptable standards of academic performance and conduct.  Please see pgs. 23 & 24 of the OCS Parent-Student Handbook for a complete list of requirements.
