Cagayan State University

The Cagayan State University (CSU) is the largest state institution of higher learning in the Cagayan Valley Region, in terms of enrollment and number of curricular program offerings. The University was established through Presidential Decree 1436, later amended by Republic Act 8292 by the integration of all publicly supported higher education institutions in the province of Cagayan.

The university is composed of eight(8) campuses in the growth areas in the three congressional districts of Cagayan; the Aparri, Lal-Lo and Gonzaga campuses in the 1st District; the Piat, Lasam and Sanchez-Mira campuses in the 2nd District; and in the 3rd District, the Andrews and Carig campuses in Tuguegarao City. Each campus is headed by an Executive Officer (CEO) except in Andrews Campus where the University President concurrently acts as the CEO. The seat of governance of the university is at the Andrews Campus, where the central administration holds office.

The university offers courses in liberal arts, social sciences, law, medicine and allied professions, business and economics, natural sciences, engineering, technology, agriculture and fisheries and teaching, among others. It offers the most graduate and undergraduate courses of all the universities in the province of Cagayan.
