In 1995, MSC was occupying the 4th floor floor of the La Suerte building along Rizal Avenue, MSC main and the former Agrix Supermarket along A. Fule St. fondly called MSC annex.
Before the end of school year 1995-1996, a local event caused the displacement of numerous students, and they frantically looked for high schools to enroll in.
The city mayor quickly responded with the establishment of public high schools, known then as the city high annexes to accommodate the students who suddenly had no school to go to. However, the government could not provide for ALL transfer students. Parents were looking for private schools to relocate their children. MSC stepped up by quickly accomplishing all requirements and applying for a high school permit.
Fortunately, everything went smoothly and the permit was granted in time for the opening of school year 1996-97. MSC annex became MSC High School, with 63 students enrolled from first to third year on its first year of operation.
Classes for the high school were only until 3 or 4 pm, so the classrooms were used by techical-vocational students until 8pm.
