Parents Plus is a charity on a mission to strengthen families and improve outcomes for children, young people, and parents by training practitioners and building the capacity of services to deliver evidence-based parenting and mental health programmes. We develop evidence-based parenting and mental health programmes in collaboration with families and services. We train practitioners to deliver and evaluate these programmes in their organisations and communities, building the capacity of community, mental health, disability, and education services in Ireland and the UK. Our approach embeds evidence-based practices in services, equips teams with solution-focused practice skills, reduces waiting lists, and improves parent engagement. The programmes create lasting, positive outcomes for families, communities, and services. Since 1995, Parents Plus has developed eight programmes for services that adapt to diverse family needs. The programmes offer universal support for all families, preventative solutions for disadvantaged and at-risk families, and targeted interventions for high-need families facing complex challenges. As a charity, all profits from training and materials are reinvested into developing new programmes to meet evolving family needs and sponsoring training and mentoring for services with limited-funding supporting high-need families. After training, practitioners join our Community of Practice, where they receive ongoing mentoring and support with programme implementation and delivery as well as access to additional resources. We believe that continued support is key to successful programme delivery and achieving positive outcomes for children, young people, and families. The Parents Plus Community of Practice is highly-valued by practitioners once they train.
