The Impact of Principal Leadership Dimensions on School Capacity

On the preliminary study, it was found that there were five critical dimensions of Principal Leadership based on sample perceptions in North Sumatra. Following those findings, this study aims to further investigate the influence of those five dimensions on school capacity. The impact of these dimensions will be useful in determining leadership strategies to maximize school capacity. The data of this research were collected by a survey method using 5-Likert scale questionnaire from school teachers and supervisors in three districts/cities in North Sumatra with a random sampling technique. 352 collected data were analyzed by multiple linear regressions with SPSS 22. The results reveal that quality management, resource management, strategic management, external communication, and instructional leadership have a significant influence on school capacity. More specifically, this turns out that instructional leadership has the highest value of influence compared to the other four dimensions, while external communication has the least influence value.
