“…To measure the effectiveness of a school, a systematic approach is needed that involves many key factors such as managerial function, individuals' performances, ethics, level of trust, culture and climate of schools, parental involvement, teachers' performances and their job satisfaction (Ostroff& Schmitt, 1993, as cite by Uline, Miller & Tschannen-Moran, 1998). Arar and Nasra (2018) summarized the definition of effective school in the educational literature in four facets: (a) the output goal approach, which claims that an effective school is a school whose achievements are above those that can be expected under defined prediction conditions; (b) the goal approach, according to which a school is effective if it achieves the goals it sets for itself within a defined period of time; (c) the resource approach, according to which a school is considered effective if it can mobilize the necessary resources to fulfill its tasks; (d) the internal processes approach, by which a school is considered effective if its functioning is smooth and its organizational climate is healthy; (e) the stakeholders' satisfaction approach, according to which an effective school is defined as a school that meets the expectations and needs of the stakeholders (parents, students, and the community); and (f) the combined approach, by which an effective school is an educational institution that works systematically and continuously for self-improvement in order to achieve its goals by maximizing its physical and human resources while maintaining the well-being of teachers and students. Hallinger and Heck (2011) determine five characteristics of an effective school: developing high expectations of students and teachers, order, discipline, emphasis on student-centered activities, and monitoring students and teachers work and strong leadership of the school principal.…”
