Good teaching poor scores Doubt cast on evaluations

first_imgWASHINGTON — In the first large-scale analysis of systems that evaluate teachers based partly on student test scores, two researchers found little or no correlation between quality teaching and the appraisals teachers received.The study, published Tuesday in Educational Evaluation and Policy Analysis, a peer-reviewed journal of the American Educational Research Association, is the latest in a growing body of research that has cast doubt on whether it is possible for states to use empirical data in identifying good and bad teachers.“The concern is that these state tests and these measures of evaluating teachers don’t really seem to be associated with the things we think of as defining good teaching,” said Morgan Polikoff, an assistant professor of education at the University of Southern California. He worked on the analysis with Andrew Porter, dean and professor of education at the University of Pennsylvania.The number of states using teacher-evaluation systems based in part on student test scores has surged in the past five years. Many states and school districts use the evaluation systems in decisions on hiring, firing and compensation.The rapid adoption has been propelled by the Obama administration, which made the systems a requirement for any state that wanted to compete for Race to the Top grant money or receive a waiver from the most onerous demands of No Child Left Behind, the 2002 federal education law.last_img read more
