Although researchers consider them powerful, teacher policy advocates are among the least studied stakeholders in U.S. public education reform today. Although plenty of attention has been given to the impact of policy on teachers' work, little research explores how teachers interpret or interact with policy. Drawing on the work of Spillane, Reiser, and Reimer (2002) on teachers' policy implementation and Coburn's (2001) work on teachers' collective sense-making of policy, this qualitative study examines the different ways in which five teachers interpreted, translated, and enacted a response to ESSA. The findings describe how contextual factors influence teachers' relationship with education policy: (a) structural supports for grassroots involvement via social networks are instrumental in mobilizing teachers, and (b) unless a more bottom-up approach is taken that enables teacher agency, sense-making, and advocacy, top-down school policies will continue to hold limited promise. The paper concludes with implications for understanding how teachers are indeed policy advocates.
