This literature review published by the Voice of Parents project in partnership with the University of Melbourne aims to identify key strategies for effective parent participation whilst understanding the barriers that impact, and in effect, compromise meaningful engagement with services. The report includes a review of national and international models where the voice and experience of parents has been intentionally sought in service design and development with a dedicated focus on those that have been successful in engaging parents (specially within overrepresented cohorts), leading to improved outcomes for children, young people and their families.
