This study primarily aimed to identify, verify/fit, and modify a conceptual model depicting the impact of school-based management to quality education when nested with high involvement model and stakeholders' morale. A total of 1260 stakeholders from SBM-implementing schools of the Divisions of Maasin City and Southern Leyte participated in this study. Data retrieved through a standardized questionnaire were analyzed primarily using structural equation modeling. This study found that internal and external stakeholders observed the implementation of School-Based Management Practices religiously, are highly involved in its implementation, and with extreme morale. The study found that: (i) School-Based Management Practices affect Quality of Education; (ii) High Involvement of Stakeholders affects School-Based Management Practices; (iii) Stakeholders' Morale is related to High Involvement; and (iv) Stakeholders' Morale affects the Quality of Education. Thus, Quality Basic Education is highly possible through a full implementation of School-BasedManagement paralleled with high stakeholders' morale. However, there is a need to strengthen the stakeholders' involvement in terms of power, knowledge, access to information, and rewards as conditions to strong implementation of School-Based Management so that collaboration would be highly visible a precursor of Quality Basic Education. For model adoption, this study recommends the model to regional evaluation and recommendation.
