Public relations practice in Thailand has developed from a primarily persuasive, one-way communication in the 1930s toward a two-way communication in the 1990s, with practitioners making increased use of management and research skills. Public relations education in Thailand began in 1965 at Chulalongkorn University. Currently, public relations courses are offered at undergraduate and graduate levels at 21 universities in Thailand, 11 of which offer a concentration in public relations. During the national entrance examinations in the early 1990s, prospective university students chose the communication department as their first choice among other social science programs. The most popular and competitive major is advertising, followed by public relations. Like other areas of communication, public relations curricula at Thai universities resemble those in the United States. A study of the course content of public relations programs at eight universities indicated that most of the schools had similar, if not identical, course requirements and number of hours required. All but one of the eight public relations programs examined included a professional internship, with most being mandatory. Thai is the language of instruction at all universities, except Assumption University where all classes are taught in English. Public relations courses at state universities are taught almost exclusively by full-time faculty, but private institutions employ both full- and part-time instructors. As more practitioners have received specialized training, their practice has gradually become more professional, moving from being product oriented toward being consumer and society oriented.
