The Triple P – Positive Parenting Program

Triple P is a comprehensive, tiered system of interventions designed to improve parenting skills, reduce child behavior problems, and strengthen family relationships. It includes multiple levels of support—from universal education to intensive, individualized interventions—allowing communities and schools to match services to family need. The program promotes positive parenting practices, emotional self-regulation, safe and predictable family environments, and prosocial child behavior.
