This research and development project aims to develop young researchers at Thailand National Sports University using the Professional Learning Community (PLC) framework. The research was conducted in four phases: studying the research problem, and developing a 5-step approach to young researchers through PLC, experimentation, and lessons learned success factors. The project had 36 participants. The results revealed that factors promoting research scored an average of 3.45, indicating a high level. Similarly, knowledge, skills, and research experience averaged 3.46, also reflecting a high level. The 5-step PLC process utilized for fostering young researchers includes establishing shared values and norms, collaborative practice toward a common goal, professional community cooperation, exposure to guidance, and reflective dialogue. As a result, six developmental approaches for young researchers were identified: self-development in knowledge, skills, and experience; preparation of research projects; writing research project proposals; implementing research projects; time management; and creating a conducive research atmosphere on campus. Implementing these approaches led to the formulation of 21 research proposals. Evaluation of these proposals yielded an average score of 3.51, meeting the criteria with a 100% success rate. Noteworthy aspects include openness, utilization of external expert networks, adjustment of attitudes towards research significance, and administrative support for research. In summary, this study underscores the significance of the 5-step PLC process as a pivotal approach in nurturing the next generation of researchers. Thailand National Sports University and other institutions can adopt this process to foster a culture of research and development among faculty and students.
