This brief offers a case study focused on Guilford County Schools (GCS), a public school district in North Carolina, to illuminate the role of continuous improvement through a "research-practice partnership" (RPP). RPPs offer a unique collaborative experience with a dual benefit: practitioners get the chance to collaborate in research that has meaningful applications for their work, while researchers have access to a rich, "real-time" opportunity to test and assess their hypotheses. These processes support ongoing improvement of the education initiative to better support important outcomes for young people and educators and inform broader implementation of similar initiatives in other contexts. The brief begins with a closer look at the definition of an RPP and then examines the process and outcomes of the RPP between CASEL and GCS. It shares insights gleaned from the partnership explores what supports are needed, the impact of the work, and the centrality of continuous improvement in sustaining the success of the initiative over the long term.
