Isabela State University Angadanan Campus had its humble beginnings. ISU-AC started as Angadanan Junior High School on August 14, 1946. After one year, it was renamed Angadanan High School. The school retained its name for 12 years until the late Congressman Delfin B. Albano worked for its conversion to Angadanan Vocational High School in 1962 by virtue of R.A. 3438. The school has expanded since then in terms of enrollment and the number of teachers because of its enriched curriculum offerings like Vocational subjects as major subjects–Food trades, Garment trades, Cosmetology, Auto mechanics, Furniture and Cabinet making, Drafting, Building Construction, Electronics, and Electricity-thereby preparing graduates not only for degree programs but for employment or self – employment for students who cannot afford to go to college, as they have been equipped with the knowledge and skills on their fields of specialization.

Thirteen years hence, that was 1975, although the school still retained its name as Angadanan Vocational High School, it started to offer post-secondary education, a 2-year ladderized curriculum leading to the degree of Bachelor of Science in Industrial Education with the different technology subjects as areas of specialization. Some of the graduates of this post-secondary education continued to a Bachelor of Science in Industrial Education (BSIE) Course at ISU Ilagan and other State Universities in Region II, while others at EARIST, Manila. The rest easily found employment or opened their own shops.

The school continued to grow as years passed by, and through the collaborative efforts of the members of the Sanggunian Bayan of Angadanan, a Municipal Resolution was drafted and endorsed to the then Assemblyman Rodolfo B. Albano, who immediately acted on it sponsoring its conversion to Angadanan Agro-Industrial College. This was realized on June 24, 1983, pursuant to Batas Pambansa Bilang 537. The main program was on Technical Vocational Education which aimed at preparing students for entrance to and advancement in the middle-level technician position in the industry. DECS Order No. 59 series 1987 authorized the offering of technical courses using competency–based instruction.

From the time the school became Angadanan Agro-Industrial College, significant events transpired. The college had become one of the Regional Learning Centers in Region II, hosting the SEDP training for First Year Secondary School Teachers in Social Studies from April to May 1988. In the following years, from 1989 to 1991, SEDP training continued during summer from April to May for 2nd year, 3rd year, 4th year for Technology and Home Economics Secondary School teachers, respectively. Since the college had been identified as a training center, it had become the favorite venue for DECS-PAVE-AVIP–sponsored seminars and training.

AAIC has been the Regional Production Center for the manufacture of steel tablet armchairs, office tables, furniture, and other fabricated materials. Different schools in the region, both elementary and secondary, had been recipients of tablet armchairs produced by the college.

In 1993, the BSIE program was opened with Automotive Technology, Electronics Technology, Electrical Technology, Industrial Arts Technology, Drafting Technology, Foods Technology, Garments Technology, Math & PEHM as special fields of specialization to choose from.

In 1996, an Associate in Hotel and Restaurant Management course was opened, which added to a tremendous increase in enrollment in college. Some of the graduates found themselves working abroad, whereas others are employed in some fine Hotels and Restaurants in Region II.

In 1999, two courses in Education, Bachelor of Secondary Education (BSEd) and Bachelor of Elementary Education (BEEd), were opened with Math, PHEM, Filipino, and T.H.E. as major areas of specialization.

As a college, the increase in enrollment was unstoppable. Physical resources were improved, additional buildings were constructed, old buildings renovated, and pathways in the campus were concreted. Items for teaching positions were allotted to the college. The college has since been committed to its philosophy, mission, and vision.

The then Angadanan Agro-Industrial College, with a land area of 16 hectares, manned with 66 teaching and non-teaching personnel, was formally integrated into the ISABELA STATE UNIVERSITY on January 8, 2002, by virtue of R.A. 7722, otherwise known as Higher Modernization Act, of 1994 and R.A. 8292 otherwise known as Higher Modernization Act of 1997 and R.A. 8760 of the General Appropriations Act of 2000 for the enhancement of quality education, rationalization of tertiary education and maximization of resources and in compliance with the provisions of the Medium Term Development Plan. The then AAIC is now one of the youngest campuses of ISABELA STATE UNIVERSITY.

In 1999, The CHED Order no. 18 s. 1999 which provides the guidelines for the integration of CHED institutions (C.S.I.s) to S.U.C.s was enacted. Pursuant to this order, the first CHED-supervised institution that was integrated into the university is the Cauayan Polytechnic College at Cauayan, Isabela. In the year 2002, three C.S.I.s were again integrated into the system, namely the Roxas Memorial Agricultural and Industrial School (RMAIS) in Roxas, The Delfin Albano Memorial Institute of Agriculture and Technology and the Angadanan Agro-Industrial College (AAIC) in Angadanan, Isabela, Causing the ISU to have nine campuses at present.

In May 2002, one of the courses proposed to be offered by the campus, the Associate in Computer Technology course, was approved by the Board of Regents, and so another course was added to its curricular offerings in June 2002. Another program, B.S. Criminology, was opened the following school year, in June 2003.

Due to its commitment to providing the necessary skills and expertise for the country’s workforce, the campus offered a Bachelor of Science in Industrial Technology in 2010 with the following major of specialization: Automotive Technology, Electrical Technology, Electronics Technology, Drafting Technology, and Foods Technology.

In 2010, BSEd and BSIndustrial Tech passed the Candidate Status of AACCUP.

The campus continuously improves its curriculum and program offerings to cater to the needs of the industry. And so in June 2011, ISU-AC offered the Ladderized BS Ind’l Technology with Automotive Technology, Electrical Technology, Electronics Technology, and Foods Technology as major fields.

June 2012 marks the opening of the Bachelor of Technical Teacher Education (BTTE) to cater to the need of the Basic Education sector, particularly to respond to the need for the K-12 curriculum. This is to train future teachers in Junior and Senior High Schools who will be offering the Tech-Voc strand.

In 2018, ISU-AC started offering a Bachelor of Science in Information Technology with a 4-year course on Web and Mobile Applications Development and Network and Security to cope with the demands of the Information Technology industry. In 2019, the campus officially opened the Bachelor of Hospitality Management, followed by the Diploma in Agricultural Technology –Bachelor in Agricultural Technology program in 2020.

The campus has continuously taken on various endeavors to further develop and improve its services for the satisfaction of its clients. ISU-AC passed the ISO 9001:2015 Certification on February 4, 2019 and has continuously passed the yearly surveillance audit and maintained the certification since. In 2021, both Bachelor of Science in Industrial Technology and Bachelor of Secondary Education passed Level 3 phase 2 in the Accrediting Agency of Chartered Colleges and Universities Accreditation. In 2022, the Bachelor of Technical Vocational Teacher Education and Bachelor of Science in Information Technology passed their Level 1 accreditation and Preliminary Survey Visit, respectively. Bachelor of Science in Criminology and Bachelor of Science in Hospitality Management are set to take on the Level 3 phase 1 Accreditation and Preliminary Survey Visit by the end of 2023.

Recently, Bachelor of Science in Industrial Technology under the Polytechnic School passed the Level III Phase 2 AACCUP Re-accreditation held on August 22-24, 2022.The program has been officially awarded Level III Re-Accredited on August 18, 2023.
