Research Synthesis of Educational Leadership Dimensions of Principals in Implementing Professional Ethics Programs

The aim of this study was to systematically synthesize the dimensions and components of educational leadership of school principals in the successful implementation of professional ethics curricula in order to provide an integrated and evidence-based model. This study was conducted with a qualitative approach and using the meta-synthesis method based on the seven-stage model of Sandelowski and Barroso. The statistical population was all valid domestic and foreign articles published between 2018 and 2025, which were identified by a systematic search in reliable databases. The quality of the articles was assessed and weighted using the CASP checklist. Finally, 28 articles (14 English and 14 Persian) were eligible for the final selection. The data were analyzed using content analysis and three-level coding with the participation of two independent coders (agreement coefficient 0.85), and theoretical saturation was achieved after analyzing 24 articles. The results led to the formation of three main themes in the form of a dynamic and nonlinear model: 1) dimensions and approaches of ethically supportive leadership (prerequisite) including ethical, transformational, distributed, and servant leadership styles along with emotional and interpersonal intelligence skills; 2) development of professional capacity and ethical organizational culture (mediator) including teacher empowerment, building trust, and forming a learner and ethically focused culture with two-way feedback; and 3) leadership in the process of implementation and achieving ethical results (outcome) including active monitoring, continuous evaluation, and achieving outcomes such as increased teacher commitment, organizational sustainability, and students' ethical education. Findings indicate that effective implementation of professional ethics programs goes beyond educational content and requires leadership and organizational transformation with a dynamic and interactive nature. Success depends on the integration of multidimensional leadership approaches, creating a supportive culture, continuous monitoring, and corrective feedback. By presenting a dynamic model, this study provides a conceptual framework for policymakers, practitioners, and researchers to bridge the design-implementation gap by understanding nonlinear and feedback relationships. Research limitations include language bias, access to full text of some articles, and differences in operational definitions of ethical leadership.
