The Cultural Affairs is composed of the Kabilin Choir, Kabilin Dance Troupe and the Kabilin Band. Each has an acronym KABILIN from the University values. The office is recruiting new members of each group every June of the opening year. Each group has its own set of officers and trainers. A scholarship grant is given to qualified members of each group.

The NORSU Choir was originally organized by Prof. Mamerto Villegas with his students in Music. Later, it was formally organized by getting members thru audition with the Choir trainor during the opening of each school year upon the approval of the Cultural Director. After having served for one (1) school year as active member, choir members are given scholarship taken from the Cultural Fund.

To be a member, one has to undergo audition, which is done every opening of the school year. Practice is everyday at 5:00 to 8:00 in the evening. Incentives are given to members who have been active members for the first semester.

Membership in the band is open to students who can play the instruments used by the band like drums, cymbals, trumpets, etc. Those who can't play any instruments could audition for flag bearers and minorettes. Audition is done every opening of the school year and scholarship is granted to active members.
