Our project aims to prevent radicalization in schools by fostering resilience through a multi-tiered system of support (MTSS). By integrating Schoolwide Positive Behavior Support (SWPBS), social-emotional learning (SEL), and mental health promotion, it enhances school climate, social belonging, and critical thinking. This evidence-based framework empowers educators and students, reducing risk factors like social isolation and identity crises while promoting long-term social cohesion.
