Many of the reforms instituted under former DC Public Schools Chancellor Michelle Rhee and continued under Chancellor Kaya Henderson have done more harm than good for the school system, according to a new report.

Under Rhee’s leadership, achievement gaps grew, test scores showed little improvement, school closings accomplished little and new teacher evaluations led to high staff turnover, according to the report by Broader, Bolder Approach to Education, a campaign started five years ago by the Economic Policy Institute, a Washington think tank.
