Rajabahat university was founded in 1975 (B.E. 2500). It was formerly known as the “Nakhon Si Thammarat Teacher Training School”. In 1975 the university was renamed “Nakhon Si Thammarat Teachers College”. The college offered two types of programs. The first was a Lower Certificate in education. This was a two year program implemented to train graduates for teaching positions at the elementary school level. The second program offered a Higher Certificate in Education. This was also a two-year program but it prepared graduates for teaching in secondary schools.
In 1975, the college began offering four-year bachelor degree programs in Education. The areas of study offered were in accordance with the Teachers College Act of 1975. A surplus of teachers resulted in the 1984 revision of the Act. The Teacher Education Department was represented by 36 teacher training colleges with a diversified curriculum to train manpower in fields other than education. The curricula aimed to equip students with competence, professional attitudes, knowledge, and the skills required to be successful in their future careers. The curricula also provided work practice opportunities and on-the-job training for specific target groups.
On February, 14th,1992 the college was conferred with the new name, Rajabhat Institute Nakhon Si Thammarat, by His Majesty King Bhumibol Adulayadej, the King of Thailand. In 1995 the Teachers College Act 1992 was revised as the Rajabhat Institute Act. The revision resulted in changing the status of the Teacher Education Department into the Office of the Rajabhat Institute Council (ORIC). The thirty-six teacher’s colleges officially became Rajabhat Institutes. The number of schools eventually increased to forty-one. According to the 1992 revisions, each Rajabhat Institute is permitted to offer various fields of study leading to Associate Degrees, Bachelor Degrees, Master Degrees, as well as Doctorate Degrees.
Rajabhat Institutes have always focused on regional areas development. At present, all Rajabhat Institutes have been re-designated as universities by the Thai Ministry of Education. They are officially recognized as “Rajabaht University”. Under this new structure all Rajabhat universities are under the authority of the Office of Higher Education Board, the same board as both private and government universities.
