This study investigates the role of educational leadership in supporting student mental health and promoting equity within schools. It examines three leadership models, transformational, trauma-informed, and equity-focused leadership, and their effectiveness in fostering inclusive school environments. By synthesizing recent empirical studies, this review identifies strategies that enhance student engagement, emotional resilience, and academic performance. The findings reveal that schools with proactive leadership in mental health experience improved student well-being, reduced behavioral challenges, and higher academic success. However, barriers such as resource constraints, inconsistent policy implementation, and a lack of specialized training for school leaders hinder the full integration of mental health initiatives. These challenges disproportionately affect marginalized student populations, underscoring the need for leadership approaches that address systemic inequities in education. This review emphasizes the importance of embedding mental health within broader school policies and practices. By prioritizing psychological safety, fostering strong school-community partnerships, and ensuring equitable access to mental health resources, educational leaders can create sustainable, supportive learning environments. The study offers practical recommendations for policymakers and school administrators to strengthen leadership practices that bridge the gap between academic achievement and student wellbeing. This research contributes to the ongoing discourse on student mental health and equity, advocating for school environments that nurture both academic and emotional growth.
