摘要：Principals play a very important role in determining the quality of education in
schools. The success of the principals to mobilize all potential in the school
environment is highly dependent on the leadership styles. Job satisfaction and
organizational commitment of the principals, teachers and administrators are
considered as indicators in determining the success of the school institution. The
objective of the research was to investigate the role of job satisfaction as a
mediator in influencing the directive and participative leadership styles toward the
elementary school principal organizational commitments in Medan. The sample of
the research was 164 junior high school principals of the school principals selected
and the data analyzed with path analysis. The results showed that (1) the principal
job satisfactions did not function positively as a mediator between directive
leadership styles and organizational commitments, (2) job satisfaction found as a
positive mediator between participative leadership styles and principal
organizational commitment.
