This article identifies the three core defining characteristics of healing environments for children and young people who have been exposed to chronic adversity and trauma. A large body of evidence highlights the pervasive and devastating developmental impacts of such exposure but there is also emerging evidence about the elements of living and learning environments that foster recovery and resilience. The Three Pillars framework has been developed to inform and empower those who live with or work with these young people but who are not necessarily engaged in formal therapy.
