PACE stands for playfulness, acceptance, curiosity and empathy. It aim’s to enable staff to engage with children and young people who experienced a range of adverse childhood situations and trauma. It was developed by Daniel Hughes, focusing on children with attachment difficulties.
The principles of PACE aim to support the development of rapport and trust in order for the adults working with children and young people to be able to develop secure, positive relationships with them. The adults most likely to form these bonds are those working closely with them such as teaching assistants, mentors, key adults etc. PACE approaches often work for other adult roles in childrens lives also.
