Measuring School and Teacher Value Added in DC, 2011-2012 School Year

In this report, we describe the value-added models used as part of teacher evaluation systems in the District of Columbia Public Schools (DCPS) and in eligible DC charter schools participating in Race to the Top. We estimated (1) teacher effectiveness in DCPS and eligible DC charter schools during the 2011–2012 school year and (2) school effectiveness in DCPS during the same year. This report updates our earlier technical reports (Isenberg and Hock 2010; Isenberg and Hock 2011).
