Abstract
This study attempted to investigate the teacher’s performance, instructional supervision, teacher’s motivation, and professional development practices of elementary and secondary public-school teachers. Three hundred teachers from Makilala West district, Cotabato participated during the conduct of this study for the S.Y. 2024. This study employed a path analysis method using quantitative approach. The data gathering tool contained an adopted questionnaire coming from the different authors. Mean, standard deviation, Pearson product moment correlation, multiple regression analysis and structural equation modeling were used in statistical tool. Based on the findings of the study, instructional supervision, teacher’s motivation, and professional development were described as high. The results also revealed that there is a significant relationship between instructional supervision, teacher’s motivation, and professional development. Instructional supervision and teacher’s motivation have significantly predicted the teacher’s performance compared to professional development. The goodness of fit results revealed that the values were not within the range of the indices criteria. This means there was no model that fits well with the data which can best explain the teacher’s performance.
