Most educators report they have improved their teaching practice as a result of their evaluation system,.
As of 2017, the RAND report says, 39 states required the use of student achievement-growth measures in teacher evaluations. Most evaluations are based on multiple measures of performance.
The survey found that 88 percent of teachers said they received feedback at least once in the 2015-16 school year, and 35 percent reported receiving it a couple times or more per year.
Teachers said it was more helpful to receive feedback from other teachers than school leaders—86 percent compared to 74 percent. Receiving feedback from an instructional coach or mentor was less common—only 36 percent of teachers reported getting it from this source—but among those who did receive this type of feedback, 82 percent said it was helpful.
