Communities In Schools contracted with EMSI to specify its economic and social returns to society through a rigorous third-party investment analysis. The purpose of this important next step is to quantify the return on investment of Communities In Schools’ 113 high school-serving affiliates in its network to taxpayers, businesses, and students. The analysis also shows the economic benefits when local affiliates go from implementing parts of the Communities In Schools model in some of their high schools to full implementation in all of their high schools.
