Calling it a “game changer,” Florida leaders made a sweeping overhaul of teacher evaluations in 2011, tying those reviews to student test scores in a push to boost educator quality and, in turn, student achievement. But by the numbers, the new evaluations have led to little change. At the end of the 2009-10 school year, before the changes, more than 99 percent of Florida’s public school teachers earned “satisfactory” ratings. At the end of the 2015-16 school year, more than 98 percent of Florida’s teachers earned “effective” or better evaluations.
