The school-age child care (SACC) field is developing so rapidly that it is imperative to conduct systematic research. Yet relatively little is known empirically regarding which feminization, commercialization, stratification, privatization of SACC. The purpose of this study is to explore America's afterschool program, and its implication about how to improve SACC system in Taiwan. The literature survey is adopted and meta-analysis of the relevant empirical research is also included. At last, nine implications on SACC are suggested: guidance system of government, strong involvement of families, professional development for staff, effective partnerships with community-based organizations, coordinating learning with regular school day, site-based management, welfare mix, supervision system, information mechanism.
