This study aimed to evaluate the 2022 Vietnam SEA Games National Program. This research used a qualitative design with an evaluation approach using the Context model, Input, Process, and Product (CIPP). The data of this study were the triangulation of questionnaires, interviews, document studies and observations. The 37 provincial sports branches and a sample of 300 athlete respondents represented each sport by random sampling. Data were analysed using description frequency analysis, particularly SPSS. This study focused on investigating four types of evaluation (i.e., Context, Input, Process, and Product Evaluation). Concerning the Context Evaluation, the research results show that the program has a solid legal and policy foundation, government goals and objectives, but it has yet to be on target. Regarding the Input Evaluation, the results show that participants, organising, financing, and committees need to be carried out correctly and improved following the development of the national potential young athlete training centre every year. Moreover, the results of the Process Evaluation indicate that sports match rules should constantly be updated following the development of the Vietnam SEA Games National Plate 2022; the implementation of the matches still needs to be adequately maximised. In addition, the results of the Product Evaluation indicate increasing public participation and interest in the implementation of national potential young athlete training centres every year, the role of the media in the publication and promotion of sports to the public is further expanding and the search for potential athletes from the community should be optimised. Based on the illustration, it is assumed that the mechanism process of the 2022 Vietnam SEA Games National Training Centre refers to the achievements obtained by athletes at the national level.
