Working parents and teachers see after-school programs no longer as optional, but as an essential support for children as they grow and develop, according to a new national study of after-school programs, released by Reader’s Digest Funds. Nearly 80 percent of parents surveyed in the study said that after-school programs helped their children cope with behavioral problems and helped them obtain new skills to meet increased demands in school.
At a time when states and the federal government are pressing harder than ever for improved academic achievement by all children, a three-year study shows that after-school programs, particularly in low-income communities, are an effective and affordable way not only to keep children safe and out of trouble, but also to keep them engaged in school.
