Sparks, S. D. (2020, March 30). This Evaluation May Keep Effective Teachers in Low-Performing Schools, Researchers Say. Retrieved April 15, 2020.

Tennessee’s overhaul of teacher evaluation in 2011 led to sharp backlash and higher teacher turnover in the immediate aftermath, but a new study in the American Educational Research Journal finds that turnover may have helped low-performing urban schools in the long run. That’s because highly effective teachers left their schools at 15 percent lower rates than did their least-effective peers, according to a team of researchers led by Luis Rodriguez of New York University.
