Betina Jean-Louis, Ph.D., is the Senior Managing Director of Research and Data Support for the Harlem Children's Zone (HCZ). Dr. Jean Louis has spearheaded HCZ's evaluation efforts since March 2002. In her capacity as Senior Managing Director, she assesses the impact of a variety of programs that are key to the short- and long-term success of poor children and families living in the zone. Dr. Jean-Louis has built an internal research and data department that is central to HCZ's noted "culture of evaluation" and that has helped the organization to serve 12,500 poor children every year with a great deal of success. As a result of this culture, HCZ is lauded for setting and meeting outcomes, its focus on accountability, and for using data to continuously improve program functioning. Working in concert with external evaluators, she and her staff investigate a wide range of programs included in HCZ's pipeline of services (early childhood education, youth development, foster care prevention, and charter schools, among others). Dr. Jean-Louis provided support in ensuring that HCZ's results and accountability orientation remain central to Promise Neighborhoods, President Barack Obama's national youth-directed community-development initiative modeled after HCZ. Routledge Press published Strengthening Families, Communities, and Schools to Support Children's Development: Neighborhoods of Promise in 2017, a book that was co-edited with Dr. Edmund Gordon and Nkechi Obiora. Dr. Jean-Louis earned a bachelor's degree from Columbia College and graduate degrees from Yale University (M.S., M.Phil., and Ph.D. in Psychology).
