This study develops and tests the REACH intervention which includes (a) a strategic communication or messaging and dissemination strategy to build school and family relationships and trust, (b) capacity building activities to improve asthma knowledge and awareness through asthma education and resources, and (c) a tool/hub that allows record and communication sharing across healthcare and educational systems to facilitate care coordination. Using a Single-Arm Non-Randomized Pre-Post Cluster Trial design, this study tests the hypothesis that use of a care coordination hub will improve school-based asthma management.
