The purpose of this study is to analyze, synthesize, and find out the size of effects by conducting a meta-analysis of functional communication training intervention study for children with autism categorical disorder in South Korea. For this, academic search database were used to collect thesis and articles published in February 2020. The final 9 studies were selected according to the criteria for selecting the target articles for meta-analysis, and the effect size for 9 articles was calculated and analyzed. The effect size was calculated using the Tau-U value. As a result, functional communication training interventions for children with autism spectrum disorder showed a significant medium effect size for increased communication behavior and for decreasing problem behavior was not significant. There were no moderator variables that significantly influenced the effectiveness of the intervention. In the methodological aspect of the study, the key indicators of fidelity, social validity, and generalization were found to be low reporting rate, and there was a problem in measuring inter-observer reliability. Based on the research results, suggestions were made to improve the quality of research and suggestions for future research.
