The research aimed to examine the components of effective academic administration involving collaborative participation from parents and the local community in small-sized schools under the authority of the Basic Education Commission. The study employed a mixed-method research approach, incorporating both quantitative and qualitative methodologies, divided into two phases. Phase 1: Examine the components of academic administration by synthesizing documents and related studies. Phase 2: Conduct interviews and verify the effectiveness of academic administration. The information providers consisted of 7 highly qualified individuals in the field of educational administration. The selection method was purposive sampling. The tools utilized included interview and assessment forms. Statistical analysis involved mean, standard deviation, and content analysis. The research findings indicated that the effective collaborative components of academic administration involving parents and communities in small-sized schools consisted of three main components: 1) The workload and scope of academic administration in small-sized schools, comprising 10 aspects, 2) Effective academic administration, consisting of 4 aspects, and 3) Collaborative management processes, involving 4 steps. The assessment results demonstrated a high level of suitability for the effective collaborative components of academic administration involving parents and communities in small-sized schools, both at the individual component level and overall. The component with the highest level was the development of an internal quality assurance system within the educational institution, including measurement, assessment, and comparison of learning outcomes. Conversely, the component with the lowest level was the development of learning resources.
