Gates Sponsored Teacher Evaluation Reform Discredited by Rand Study

Education Week reports here on a new Rand Corp. study concluding that half a billion dollars spent by the Gates foundation on three large school systems to totally revamp teacher evaluation produced no real improvement in student performance. Unfortunately, the Obama education department had convinced most of the country to implement the same defective evaluation system at the same time before we could see the results of the study. So just like implementation of Common Core, which was also pushed upon school systems by the Gates Foundation,  an expensive and time consuming teacher evaluation system was implemented without knowing if it would work. All that money and effort just drove a lot of good teachers out of the profession without improving student learning.

The new teacher evaluation system sponsored by the Gates Foundation and the Obama Race to the Top grants included basing teacher evaluations on student test scores and intensive observation of teachers using a strict rubric for teaching methods. The end result would supposedly identify the highly effective teachers as well as the ineffective ones. Then, teachers could be fired or awarded merit pay based upon their ranking in the evaluation system. Some reformers had theorized that such a system would dramatically improve student academic performance. There was even a theory that low performing students could be brought up to grade level performance by being exposed to highly effective teachers for only three successive years. It was believed that socioeconomic factors affecting student performance could be ignored by just fixing the teachers. These theories have now been proven wrong. Scapegoating teachers for problems of society just does not work, but it does drive good teachers out of the profession, and discourages bright young persons from entering the profession. Result: a serious teacher shortage.

When education reform is found to be ineffective, why are schools still required to continue doing it?

Louisiana went whole hog on VAM (basing teacher evaluations on student test scores) and highly structured teacher observation because we were told that there were findings that proved that any student could be converted into a high academic achiever after only three years of instruction by highly effective teachers. This theory developed by Hanushek and others unfortunately was not scaleable (didn't work) even though now our entire teacher evaluation system has been revised to supposedly identify highly effective as well as ineffective teachers. Louisiana law now bases teacher job security and even merit pay on highly dubious student performance measures. It turns out that VAM scores for each teacher are extremely unstable (and dangerously irrelevant) from year to year. It turns out that very little of a teacher's VAM score depends on her/his performance in the classroom. Socioeconomic factors and noise in the highly imprecise VAM formulas routinely outweigh the actual performance of the teacher. In addition, teachers teaching untested subjects have a major advantage over teachers of tested subjects in winning merit pay and job security.

Here is an interesting fact about Louisiana teacher evaluation reform: Did you know that the new teacher evaluation rubric was actually designed by a person (Rayne Martin) who had never taught or evaluated teachers. Before coming to the Louisiana Education Department, Martin had worked for the Housing Authority in Chicago. She had never received teacher training or evaluation training. This is typical of most of the education "deform" we have been subjected to in the last 13 years. Unfortunately, here in Louisiana, we are still stuck with VAM and the new observation matrix for the evaluation of teachers that was developed by a non-teacher who has long left Louisiana.

So what did the Rand study find in its nationwide evaluation of VAM and the accompanying high stakes evaluation of teachers? Basically it has made no difference whatsoever in student performance nationwide. Zero results! After all that money and after the gnashing of teeth by so many thousands of teachers. We have produced however a growing teacher shortage, probably because all those potentially "highly effective" teachers found that they could make more money in jobs that did not use a form of torture to rate their performance.
