The K-12 Coherent Instructional Systems portfolio of the Bill & Melinda Gates Foundation’s U.S. Program seeks to support a cohort of provider-local education agency partnerships focused on implementing coherent instructional systems (CIS) built around high-quality middle-years mathematics curricula in contexts that serve secondary students who are experiencing poverty, and Black, Latino, and/or English Learning-designated students ("priority students").  

As a Learning Partner for the Effective Implementation Cohort (EIC), the National Implementation Research Network (NIRN) at UNC-Chapel Hill's Frank Porter Graham Child Development Institute seeks to support the cohort of Provider-Local Education Agency partnerships in their implementation and measurement efforts related to their scale-up of high-quality mathematics curricula. In addition, NIRN will collect and analyze data to answer the investment’s learning questions within the cohort-wide learning agenda. NIRN is committed to providing the Bill & Melinda Gates Foundation, the EIC, and the larger education community insight into a definition of effective implementation of CISs that ensures improved outcomes for priority students and a refined theory of action that can be applied to other CIS work and curriculum implementation more broadly.
