The purpose of this paper is to report findings from an exploratory study of the early implementation of the Common Core Learning Standards in New York City by a sample of charter management organizations (CMOs) and Children First Networks (CFNs). Using the existing literature on policy implementation—specifically the concepts of boundary spanners and mutual adaptation—this research investigated the role of networks as they facilitated the implementation of the new standards. We conducted in-depth interviews with leaders in both types of networks. The interviews focused on the strategies used to implement the Common Core and the challenges faced in the process. Our findings included evidence of varying capacity among CFNs and CMOs. More decentralized networks expressed greater difficulties with the transition, and the existence of a distinct network-level department with exclusively instructional responsibilities facilitated the adoption of the standards.
