This case describes a longitudinal study of high school students' academic and social motivation and social networks at school. When working together as a PhD student and advisor, we built a university-school partnership and conducted a student survey project that spanned 5 years. A portion of the project data was used for a dissertation on students' social networks and their academic and social motivation. The case study describes the project context and development of the partnership, the research design and procedure, and an overview of the analysis and dissemination of complex data to school staff. Particular attention is paid to the use of social network analysis as a methodological tool for assessing social relationships in schools. The longitudinal nature of the study required maintenance of a sustainable relationship with the school, which is discussed throughout. We conclude the case with lessons learned.
