This study examines whether high-quality after-school programs operating in high-poverty communities improve the academic, social, and behavioral outcomes of participating students.
The study reported higher standardized math test scores and better behavioral outcomes for students who regularly participated in high-quality after-school programs than for students who spent substantial after-school time without adult supervision.
