D.C.'s teacher evaluations are overly subjective

Thursday, August 26, 2010

I am a teacher in the D.C. public schools, and I just got my IMPACT teacher evaluation. On a scale from 1 to 4 (with 4 being the highest), my final score is 3.18. My evaluation has two components: an objective component based on student test scores and a subjective component based on the opinions of people who have evaluated my job performance. On the objective half, my score was 4.0, but on the subjective half, it was only 2.36.

There are lots of ways to interpret this huge discrepancy. The evaluators may not have followed the directions correctly; the directions the evaluators were given may not have been correct; the evaluators may have falsified the numbers for some reason, etc.

You can understand why D.C. public school teachers are concerned about this IMPACT evaluation system. It looks like the school system doesn't have a clue about what a good teacher looks like.
