This study was designed to investigate the current practice of continuing professional education in the library science departments of teachers colleges and universities in Thailand and the role of the library science department in continuing professional education for librarians. In order to accomplish this task, two questionnaires were developed and administered to 236 chairpersons and library school faculty of 31 tecahers colleges and 9 government universities. Of the returned questionnaires, 72.88% were usable. Data were analyzed using percentage and a contingency chi-square test. The major conclusion of the study was that while the library science departments of teachers college and universities in Thailand provide to some extent, all 20 continuing education items of the Association for Library and Information Science Education model, only two were identified as being provided by more than a majority of institutions.
