This study aimed at identifying the successful leadership practices for solving school problems by the principals of the secondary schools in Irbid educational area. It also aimed at identifying the differences in the principals’ evaluations of these practices by the variables of gender, academic degree, and work experience. The sample consisted of (473) male and female principals. They completed a 40-item questionnaire developed for the purposes of this study. The questionnaire contained four domains: successful leadership practices for teachers’ problem-solving; students; local community and parents; and school environment and supplies. The results of the study showed that successful leadership practices for school problem-solving were high, except for the local community and parents’ problem-solving domain, which was at medium degree. The results further showed statistically significant differences among the principals’ responses to the successful leadership practices attributed to the gender, academic degree and work experiences variables. The study recommended focusing on achieving the partnership principle between the school and the local community, and activation of the principal’s role as an educational leader at school.
