This research was intended to provide a basic data on the study of utilization of assistive technology to improve vocational ability for people with intellectual disabilities. As this study was literature review, it was analyzed the qualitative level, methodology contents, and general characteristic of a study, related assistive technology application for improvement of vocational ability in people with intellectual disabilities. The results of this study were as follows; Firstly, experimental environments mostly consisted of separated experimental conditions and design employed multiple probe design; Secondly, all of studies were involved in the standard of selection of subjects, but the proportions of study describing the contents related to subjects was low. The proportions of study describing the behavior-control and exterior-variable control method was low; Thirdly, most study evaluated independent variable and presented fidelity of treatment but, the presentation of social validity was proved to be insufficient. In order to effective application of assistive technology in vocational rehabilitation, it is need a evidence that the application of assistive technology is evidence-based practice in vocational rehabilitation. We also need a supplementation between methodology contents and qualitative level of study in more study.
