This study aims at identifying the role played by school principals in the Governorate of Ma'an to strengthen intellectual security of the school students; and identifying whether there are statistically significant differences in the roles of principals attributed to the variables: gender, academic level, and years of experience in administration. To achieve this, the researchers adopted the descriptive approach which is appropriate for the nature of this study. Data were collected and analyzed by using a questionnaire that determines the role of school principals in the promotion of intellectual security. The questionnaire includes three areas: the role of principals toward teachers, the role of principals toward school activities, and the role of principals toward community service. The study sample consisted of 120 male and female school principals in Ma'an governorate. The results showed that the arithmetic means of the three domains in the questionnaire ranged from (3.547-4.129) with high degree of agreement; where the domain: "the role of principals toward teachers" scored the highest value, and the domain: "the role of principals toward community service" scored the lowest value.
