Ofelia A. Rebong was also appointed as the first president of the college in the same year. Rebong's term was seven years long and staff development was infocus during this period.

OMSC expanded in the 1991-92 school year, with the absorption of Occidental Mindoro Community College in Mamburao by the state college. The community college became a satellite campus of the OMSC and became known as the OMSC-Mamburao Campus, which offers baccalaureate and non-degree courses. A 98.8725 hectares (244.319 acres) plot owned by the Organization for the International Scientific and Cultural Advancement (OISCA) was also acquired by the state college through the Provincial Board and Provincial Development Council.

Sofronio S. Sanqui was appointed college president on 19 December 1994 and sworn into office on 29 December, the same year, by DECS Secretary Ricardo T. Gloria, after the retirement of Rebong. Sanqui was the vice president for Academic Affairs and dean of the Graduate School before his appointment. Sanqui focused on human resource development and student development.

In the year 2000, by virtue of Republic Act 8760 (also known as the General Appropriations Act) significant reforms were brought about in the educational system, specifically to OMSC. It became the host to CHED-supervised institutions in the province, namely the Occidental Mindoro Polytechnic College (OMPC) in Murtha, San Jose, Occidental Mindoro and the Pedro T. Mendiola, Sr. Memorial Technological and Polytechnic College in Brgy. Bagong Sikat, San Jose, Occidental Mindoro. With the integration, OMPC became known as the OMSC-OMPC Campus, while the PTMSMTPC was renamed to OMSC-PTMSMTPC and is now situated at the Labangan Campus.

After 15 years of sterling and dedicated service to the Institution, Sofronio S. Sanqui, the second college president, retired. He was replaced by Arnold N. Venturina, when the Board of Trustees of the College elected him on 11 September 2009. With the change of administration, several significant changes in the programs and policies of the college were also enforced.

Three months to Venturina’s presidency, President Gloria Macapagal-Arroyo signed RA 9747, also known as an “Act renaming Occidental Mindoro National College as the Occidental Mindoro State College”, on 10 November 2009, whose principal sponsor was Congresswoman and Deputy Speaker, Amelita C.
