Do Low-Income Students have Equal Access to the Highest-Performing Teachers?
Glazerman, Steven; Max, Jeffrey - Mathematica Policy Research - 2011
Most research on equal educational opportunity has focused on inputs like teacher experience and degrees. This brief estimated teachers’ value added (contribution to student achievement growth) and measured access to highest-performing teachers in high- and low-poverty schools. Across 10...
