Governments have long focused on supporting parents through social services and schools as key platforms for promoting health and addressing educational and societal issues. However, while civil servants believe schools underestimate their capacity to support parents, educators argue that parenting support is not part of the curriculum. In Sweden, teachers are required to inform parents about their children's development, rather than offer parenting support services. Research shows, however, that parental involvement increases children's success in school. Against this background, the intervention of a family support 101 worker (FSW) is a novel educational move. Two questions are addressed, “How does the FSW promote school-home relationships?” and “What effect does this work have on pupils’ prerequisites to succeed in school?”. Georg Simmel describes trust as "a hypothesis certain enough to serve as a basis for practical conduct," emphasizing that it can bridge the gap between the known and unknown. He introduces the triad, involving three elements, as “a social framework that transcends both members of the dyad” which can enhance relationships by allowing a third party to mediate. The project is a research collaboration between academics and school staff. Data collection methods include surveys for parents and teachers, reflective protocols for teachers, interviews with school leader and FSW as well as parent and teacher group interviews. This approach allows each stage’s results to inform the next, creating a progressive contextual framework for content analysis. Expected outcomes include; A strong statement from school personnel and parents about the value of school-based FSWs in promoting student success; Results that can be adopted by other schools, encouraging leadership to invest in family-school partnerships through FSWs; A meaningful contribution to international research on school-based parenting support, highlighting the role of family support workers in enhancing family life and child learning and development.
