Carol Burris, the brilliant executive director of the Network for Public Education, has written the definitive account of Bill Gates's disastrous teacher evaluation project, which wasted $215 million of his dollars, but over $350 million of state, local, & federal dollars (ours). Dr Ravitch urges you to read it. Not many are likely to read the 600 page RAND report evaluating the project. Burris did. The study examined the effects over six years; a key feature was teacher evaluations systems similar to NY's. It concluded that the IP project did not improve either student achievement or the quality of teachers. In fact, it did more harm than good. The cost was astronomical. Taxpayers paid most of the costs via local or federal tax dollars and, resulted in increased teacher turnover.The report found no evidence that the quality of the teachers recruited improved."
