Office of Student Activities


In our desire to actively contribute to the imminent and urgent need for nation-building, the Office of Student Activities seeks to form students in organized groups to become leaders who will be active citizens in the task on national development.

OSA aims to do this by making organized groups capable of formation and providing them a venue conducive for them to flourish.

The OSA sees to the effective planning, implementation, and evaluation of activities within and among campus organizations. It provides a variety of co-curricular programs and activities that contribute to student development and support the school’s objectives. It guides and assists recognized and non-recognized organizations on campus and creates guidelines for student activities that insure loyalty to the vision of the Ateneo. The office also creates programs that attract more students and faculty members to extra and co-curricular activities of the Loyola Schools.
