Full-service community schools are viewed as an approach to improve educational opportunities and outcomes for underserved student populations. The realization of these goals, however, is not guaranteed. According to Richardson's (2009) research-based model of highly effective community schools (HECS), the effectiveness of full-service community schools depends on 3 interrelated components: leadership, partnerships, and organizational development. This qualitative case study uses the HECS model to examine different levels of effectiveness among 3 full-service community schools in an urban district in the eastern United States. The article concludes with a discussion of the implications of Richardson's model for practice and research.
