The "Promoting Alternative THinking Strategies (PATHS®)" program is a curriculum that aims to promote emotional and social competencies and to reduce aggression and behavior problems in elementary school children. "PATHS"® is delivered through short lessons given two to three times a week over the school year. The program is based on the principle that understanding and regulating emotions are central to effective problem solving. The lessons focus on: (1) self-control; (2) emotional literacy; (3) social competence; (4) positive peer relations; and (5) interpersonal problem-solving skills. There is a separate curriculum for each grade. This What Works Clearinghouse (WWC) intervention report, part of the WWC's Supportive Learning Environment topic area, explores the effects of the "PATHS"® program on student emotional awareness, social interactions, behavior, and academic achievement. The WWC identified 35 studies of the "PATHS"® program. Two of these studies meet WWC standards. The evidence presented in this report is from studies of the effects of the "PATHS"® program on students-- including 70% White, 11% Asian, and 8% Black students, and students with and without disabilities--spanning grades 1 through 5 in both urban and suburban districts. This intervention brief provides an overview of the full report. [For the full report, see ED611242. For the Intervention Snapshot, see ED611244.]
