Abstract This study aimed to examine the effect of leadership skills acquired from the Leadership Diploma on the motivation of government school principals in northern directorates. The population included in this study included 315 government school principals in Jenin, Qabatya, and Tubas Directorates. A quasi-experimental design was used; the study sample included 100 principals who had been trained through the Leadership Diploma. A questionnaire was used to collect data from the school principals. The results showed that principals who completed the Leadership Diploma had higher motivation, a sense of responsibility, and self-efficacy than the control group. Also, the study demonstrated that there was no effect of the training received during the leadership diploma on the motivation due to age, gender, specialization, and qualification. However, there was an effect of the principals’ experience, in favor of 5 to 10 years. The study recommends starting the Leadership Diploma program to all government school principals from the first year.
