This systematic review reviewed the trend of providing the transition service in the occupational therapy process for students with disabilities. A total of 4,739 articles were entered into international and Thai databases such as Scopus, PubMed, ERIC, Cochrane, ProQuest, and OTseeker, CUIR, NRCT, TNRR, and ThaiLIS between 2005 and 2020. This study was guided by the research question, "what is the current evidence of the transition service being provided to students with disabilities in the occupational therapy process?" The Population Intervention Comparison Outcome (PICO) and Occupational Therapy Practice Framework (OTPF)-III were used to design the search terms and evaluate the methodological quality of the data. The results found that 15 articles met the criteria for consideration. There were two articles at level I, one article at level II, two articles at level III, seven at level IV, and three at level V of evidence. Most of the studies had a school-based approach and appropriate methodologies, but less psychometric property testing of research instruments.
