“…Using a policy networks approach, education researchers have produced a growing body of research on the rise, spread, and implementation of Common Core State Standards in American education. This research describes how a small group of policy entrepreneurs influenced the problem formulation and agenda setting stages of the CCSS initiative (e.g., Kornhaber, Griffith, & Tyler, 2014;Kornhaber et al, 2017); how these same policy entrepreneurs then mobilized resources from private foundations and the federal government to orchestrate uptake of the CCSS by states (McGroarty & Robbins, 2012;Layton, 2014;LaVenia, Cohen-Vogel, & Lang, 2014;Kornhaber, Barkauskas, & Griffith, 2016); how these policy entrepreneurs also worked with advocacy groups and think tanks to support and defend the CCSS initiative at various stages of the policy process (McDonnell & Weatherford, 2013a;McDonnell & Weatherford, 2013b;McDonnell & Weatherford, 2016;Kornhaber et al, 2017); and how state education agencies cooperated with non-governmental service providers as the CCSS initiative moved to the policy implementation stage (Russell et al, 2015;Hodge, Salloum, & Benko, 2016;Moffit et al, 2018;Salloum, Hodge, & Benko, 2020). The goal of this paper is to extend policy networks research on the CCSS initiative by shifting the focus away from examining the CCSS as a case of policy change occurring within a large, national policy community and toward an examination of the CCSS as a case of instructional reform taking place within the K-12 school improvement industry more broadly conceived.…”
