The purpose of this study is to evaluate the level of service quality at festivals and derive improvement plans for future festival development based on the results. As demonstrated in various previous studies, service quality has a significant effect on visitors' post-intentions. Based on these important service quality variables, 366 available samples were collected through empirical research, and finally, Revised IPA was applied. Through empirical analysis, the service quality level of the 2022 Daejeon Science Festival was confirmed, and meaningful implications for the attributes that needed improvement were presented. In addition, the limitations of the study and the direction of future research were presented.
