Despite the economic challenges faced by the community over the years, the school has continued to thrive and provide quality education.

To accommodate its growing student body, the school operates on a two-shift system (morning and afternoon sessions) and has established extension campuses in Barangay Pala-o and Tambacan, Iligan City.
