The students of MIS were sons of Manobo "datus" from the regions of Simulao, Adgawan, Umayam, Gibung, and Wawa-Ojot while the principal was Carlson Berger with Mr. and Mrs. Joseph Kempt, Liberato Fortun, and Ciriaco Viajar as members of the faculty.
Pupils lived in Bunawan with their parents or relatives otherwise pupils coming from the municipalities of Cuevas, Trento, Libertad, Veruela, La Paz, Loreto, Prosperidad, Talacogon, San Luis, Esperanza and Lianga, Surigao were accommodated in the dormitory with free clothing, bedding, and subsistence.
Luna arrived in September 1948 and immediately moved to provide facilities, books, equipment, working animals, food and other needs until his replacement by Domingo C. Gabertan on August 4, 1949.
Gabertan decided to relocate the school campus on higher ground due to the yearly flooding on the old site.
Gabertan, however, was transferred to Negros Occidental National Agricultural School in Kabankalan on August 16, 1956, after he was sent to the United States for one year advanced studies.
During his time additional buildings were constructed like the girls' dormitory, social hall, and practice house, until his promotion to the General Office, Manila in the later part of 1960.
Alava was later replaced by Felipe C. Badua who was promoted as principal effective on June 23, 1967, and as vocational school administrator I on July 1, 1974, until his retirement on May 27, 1985.
The CMU (Central Mindanao University) Off-Campus Institute at SANAC started offering the first year of the four-year general collegiate academic course during the first semester of SY 1979–80 with members of the faculty who were trained at CMU, Musuan, Bukidnon, for two summers, acting as affiliate instructors.
The first two years of this course admitted NCEE and non-NCEE qualifiers, leading to the Diploma in Agricultural Technology (D.A.T.
Nicasio T. Domingo Jr., who replaced Badua as vocational school administrator, exerted efforts to increase students achievement by upgrading the quality of instruction; curriculum improvements; faculty and staff development; and acquisition of needed field, laboratory, and library facilities.
On March 1, 1995, President Fidel V. Ramos signed RA No 7932 transforming SANAC into Agusan del Sur State College of Agriculture and Technology (ASSCAT).
The 60 million pesos grant-in-aid for ASSCAT was in the form of refurbished theory room, library, farm mechanics shop, laboratories for science, crop and food processing, nursery, and Community Outreach Center (COC).
Computers, typewriters, overhead-projector, photocopier, recent editions of library books, course materials and other references were provided.
ASSCAT's agricultural programs support the provincial and regional thrusts as spelled out in the Caraga Medium Term Development Plan.
As of 2014[update] nine degree programs were offered: The library was a donation from the Bunawan LGU through the effort of Mayor Gilbert G. Elorde.
Books and electronic resources such as VHS, CDs and transparencies worth about 4.5 million were donated by Congressman Rodolfo G. Plaza, who also assisted with the installation of the College Speech Laboratory.
The proceeds from Income Generating Projects (IGP) have augmented the services and facilities needed by the students and faculty.
The oil palm, coffee and rubber plantation projects income helped for the repair and renovation of the ceilings of some old and dilapidated buildings.
The college cafeteria functions as an IGP, but it has very limited income because nutritious foods were served at minimal costs.
Animal projects are on the break-even phase but being maintained as Students Instructional Units (SIUs) necessary for the agricultural programs.
