The aim of this systematic review was to map the peer-reviewed literature (2009–2019) relating to school involvement with wraparound models in the support of students with complex needs. Specific research questions addressed explored the evidence base of the efficacy of wraparound with these students and barriers and enablers in the provision of wraparound services. Database searches were conducted and a total of 50 articles were identified. The analysis revealed eight different aspects of wraparound efficacy, with mixed results. Nine factors were identified as having a positive enabling, or disabling, effect on the provision of effective wraparound services. The wraparound programs were varied in their nature and in their successful implementation, with time to allow the program to mature and adherence to the 10 principles of the wraparound process emerging as enabling factors for wraparound success.
