This report identifies and reviews 34 programs that have been used as after-school programs by schools or communities, including extended-day programs and some supplemental school programs that have potential for after-school use. Five categories of programs are reviewed: (1) language arts after-school programs; (2) study skills programs; (3) academic programs in other curriculum areas; (4) tutoring programs for reading; and (5) community-based programs. The review discusses these programs in terms of the evidence of their effectiveness for improving student outcomes and the evidence of their replicability in other locations. The report also summarizes correlational research studies that have examined the effects of other after-school programs. Based on the program evaluations and the correlational research, the study identifies academic, recreational, and cultural components of effective after-school programs and presents recommendations for implementing these components. The report concludes that stronger evaluations of these and other current after-school programs must be conducted, and other well-designed programs need to be developed and evaluated to produce after-school programs that are effective and replicable for increasing student achievement and other student outcomes. Appendixes list contact persons for the programs reviewed and summarize the categorization of the programs. (Contains 104 references.) (Author/SLD)
