  • Dr. Julie Marsh is an Associate Professor at the Rossier School of Education at USC and Co-Director of Policy Analysis for California Education (PACE). Marsh specializes in research on policy implementation, governance, and accountability. Her research blends perspectives in education sociology, and political science. Over the past 20 years, much of her research has examined school districts as central actors in educational reform, including the roles played by central office administrators in both interpreting and creating policy, as well as the roles of other district actors – school board members, union leaders, citizens, parents, foundations, university partners, and community organizations – in advancing system-level reform and enhancing district capacity. Another focus of her research has been the implementation and effects of various accountability policies, including studies of the No Child Left Behind Act, performance-based evaluation and compensation, student promotion and retention policies, and charter schools. Marsh has also closely examined policies intended to support teachers and improve teaching, including research on data-driven decision-making, literacy coaches, professional learning communities, and math and science curricular reforms. Cutting across this research is a focus on the political dynamics of educational reform, the democratic nature of these efforts, and the effects of policy on practice. Marsh is currently co-PI of a study of Los Angeles Unified School District’s Teacher Incentive Fund-supported human capital reforms, as well as studies of teacher evaluation in New Orleans and STEM curricular reform. She was also recently Principle Investigator (PI) of a Spencer Foundation-funded study, Bridging the Data-Practice Divide: How Coaches and Data Teams Work to Build Teacher Capacity to Use Data, and co-PI of a study of LAUSD’s Public School Choice Initiative. Recent publications include: “Using data to alter instructional practice: the mediating role of coaches and professional learning communities” (Teachers College Record), “Trickle down accountability? How middle school teachers engage students in data use” (Educational Policy), “Democratic engagement in district reform: The evolving role of parents in the Los Angeles Public School Choice Initiative” (Educational Policy), and “Recent trends in intergovernmental relations: The resurgence of local actors in education policy” (Educational Researcher). She is also author of Democratic Dilemmas: Joint Work, Education, Politics, and Community (SUNY Press) and co-editor of School Districts and Instructional Renewal (Teachers College Press). http://usc.academia.edu/JulieMarsh/.

A Big Apple for Educators: New York City’s Experiment With Schoolwide Performance Bonuses found that the New York City schoolwide performance bonus program had no effect on students’ test scores, school report cards, or the way teachers reported doing their jobs. The New York Times was among the news outlets to feature the report.
