The Every Student Succeeds Act (ESSA) emphasizes evidence-based interventions while providing new flexibilities to states and districts with regard to the use of federal funds, including funds that could be used to support social and emotional learning (SEL). This report is a companion to "Social and Emotional Learning Interventions Under the Every Student Succeeds Act: Evidence Review," which assessed evidence on SEL interventions against ESSA evidence tiers. This report serves as a companion guide to the evidence review by providing guidance on how to assess local needs relative to SEL and how to identify appropriate evidence-based interventions that address those local needs. This report also provides introductory information on implementing, monitoring, and evaluating selected SEL interventions. While this guide is especially pertinent to educators looking to leverage federal ESSA funds to support SEL, it can support any educational leader in responsibly allocating scarce resources to support school-based SEL interventions.
