Whole-School Trauma-Informed Policies Reduce Exclusion Risk but Lack RCT Validation

The MedicalXpress article emphasizes everyday interactions and trusted adults over isolated workshops, aligning with ACE studies linking trauma to academic and relational difficulties. However, it understates implementation variability: zero-tolerance policies persist in many schools despite guidance, potentially increasing retraumatization. Related evidence from a 2022 Lancet Child & Adolescent Health observational cohort of 12,000 UK pupils found trauma-exposed students had 2.3 times higher exclusion odds, mitigated partially by staff training but not eliminated. A 2023 BMJ Open analysis of 180 schools adopting similar frameworks reported 12% absolute drops in suspensions versus controls, though selection bias limited causal claims.
