The PARS model of playwork practice was developed by Dr Shelly Newstead from research into the origins of playwork from the adventure playgrounds set up in the UK just after the Second World War. This article considers why and how this theoretical model of playwork as a form of professional practice is now being applied and developed by practitioners in Brazil, contributing to the creation of an international ‘community of practice’ (Wenger et al, 2002). It describes how PARS’ underpinning philosophy and model of practice provide a strong foundation that values playwork and supports the development of a shared language and identity for PARS playwork practitioners across Brazil and around the world.
