DIOP full membership requires the applicant to have completed an accredited postgraduate training (Master or PhD / Doctorate) in I-O psychology. This I-O psychology degree has to be a second degree beyond a first degree in psychology. ​

Two universities in Hong Kong offer a postgraduate degree in I-O psychology: Department of Psychology, the Chinese University of Hong Kong, and Department of Psychology, Lingnan University. Please refer to their relevant websites for information. 

Postgraduate training programs in I-O psychology are also available from overseas institutions. These qualifications will be vetted by DIOP on individual basis. In general, programs that are accredited by the American Psychological Association, Australian Psychological Society, British Psychological Society, and Canadian Psychological Association often will be considered by DIOP to have fulfilled the necessary criteria.
