Schools across the province of Alberta are increasingly diverse in terms of student backgrounds, circumstances, and needs (Alberta Education, 2017). In order to respond to the needs of a diverse student population, many schools are providing supports targeted to children and youth identified as being at risk for poor outcomes. The Wellness, Resiliency, and Partnerships (WRaP) project, initiated in 2009, was born out of recognition for the need to provide individualized, strength-based supports to students with Fetal Alcohol Spectrum Disorder (FASD). For eight years, WRaP success coaches aimed to provide innovative, collaborative, strength-based services and supports to promote the success of students with FASD in Alberta schools. The project initially targeted junior and senior high school students with FASD. Over the project's most recent two years, the project expanded to serve elementary schools, as well as students with complex needs in addition to those that arise due to FASD. The aims of the project were to maximize school engagement, increase academic success, and enhance social, emotional, and physical well-being. In addition, coaches worked to enhance school and family capacity to support students with complex needs, and to build partnerships for youth to access supports at home, at school, and in their communities. Overall, the WRaP project demonstrated significant growth and positive outcomes in terms of building school capacity to support students with complex needs including FASD. We will draw on data from four years of annual interviews and focus groups conducted with WRaP success coaches and school personnel to describe the key processes, successes, and challenges involved in building school capacity through the WRaP project in Alberta schools.
