The Harlem Children's Zone, a broad-based initiative designed to meet the educational, health, and social-service needs of residents in a 97-block area of New York City, includes two public charter schools that serve some 1,200 students in elementary, middle, and high school. A new rigorous study finds dramatic academic gains which are closing the black-white achievement gap in most of the categories examined. The findings suggest that "either the ... public charter schools are the main driver of the results or the interaction of the schools and the community investments is the impetus for such success," write the study's authors. “Community investments alone cannot explain the results.”
