The Preschool-to-Postsecondary Evidence Synthesis Task Orders (PESTO) produce practice guides, intervention reports, and associated technical assistance in specific areas. Under Assisting Students Struggling with Behavior in Grades K-12 (PESTO Task Order 1), the contractor prepared practice guides and related products informed by a systematic review of evidence on the impacts of school-based behavior interventions on students in kindergarten through grade 12 who have been identified as struggling with behavior, at risk of social and behavioral programs, or in need of interventions to address externalizing behaviors, internalizing behaviors, or both.
