OCB is a fundamental aspect of all human organizations. This review paper aims to emphasize the significance of organizational citizenship behavior (OCB) within educational environments. Educational institutions possess leaders, employees, and tangible and intangible resources. The dimensions of organizational citizenship behavior (OCB), such as altruism, civic virtue, courtesy, consciousness, and sportsmanship, are highly significant in enhancing the strength of relationships among employees, leading to improved group performance and positive outcomes for organizations. Nonprofit service institutions, such as schools, rely on employees expressing OCB to achieve improvements in their outcomes. Organizational citizenship behavior (OCB) aims to mitigate negative behaviors and promote positive workplace behaviors. Research has demonstrated the advantages of critically analyzing the emergence of organizational citizenship behavior (OCB) in both educational leaders and teachers. This review examines the construct of organizational citizenship behavior (OCB) in educational settings, specifically addressing its role, types, existence, measurement, and importance. This study offers recommendations for policymakers, administrators, and teachers to facilitate the promotion of organizational citizenship behavior (OCB) in schools.
