This study aimed to evaluate the levels of participation of the school stakeholders to the different school-initiated activities and the implementation of school-based management (SBM) in selected schools in the Division of Davao del Sur for the school year 2014-2015 using a descriptive-correlational survey research design. A researcher-restructured questionnaire was answered by the 13 school heads, 56 teachers, and 50 stakeholders who formed part as respondents of this study. The data were statistically analyzed using mean, analysis of variance (F test), t-test for independent sample, Pearson r and t-test for the significance of r as statistical tools. In terms of the level of participation of the school stakeholders to the different school-initiated activities, a moderate descriptive rating was found. The level of SBM implementation was found to be at Exceeding the Minimum Standard. The level of participation of the school stakeholders to the different school-initiated activities can be significantly affected by the level of SBM implementation.
