“Test-imony”: Dr. Wayne Au’s address to Washington State Legislature against new teacher evaluation bill
Politicians in Washington State are attempting to reduce educators to lifeless bits of inaccurate data. House Bill ESSB 5748, which would explicitly link teacher evaluation to standardized test scores, was recently introduced into the Washington State Legislature. Dr. Wayne Au, the University of Washington Bothell’s 2015 Distinguished Teaching award winning professor, joined scores of others in Olympia on Monday, March 30th, to express opposition to this educationally unsound proposal. In fact, there were so many there that wanted to use their testimony to “test-defy,” that after both sides had presented arguments, there were still 322 more people who wanted to speak againstthe bill but there wasn’t enough time. After Au’s schooling, the full transcript of which appears below, at least these politicians can’t plead that they were ignorant of the unscientific approach and harmful effects that tying teachers’ evaluation to tests scores will have on intellectual and emotional process of teaching and learning. Professor Au sent me the following preface to his testimony:
I was invited to testify by Representative Sharon Tomiko-Santos, Chair of the Washington State House of Representatives Education Committee. She wanted me to bring a research-based perspective to the discussion of ESSB 5748, which would explicitly link teacher evaluation to standardized test scores. The audience was the Education Committee, so one thing I want readers to know is that I was making an argument to folks who believe the tests are a valid measure. Plus I only had 2 minutes to testify, which means a lot of arguments that could have been made had to be omitted due to time constraints. So while there are so many good arguments to make against using standardized test scores to evaluate teachers, I had to choose a few particularly clear and sharp ones that I thought would be the best at directly challenging the ESSB 5478. Also I want to publicly thank my partner, Dr. Mira Shimabukuro, for her help in the editing and crafting of the final statement.
Dr. Wayne Au’s Testimony to the Washington State House Education Committee Regarding House Bill ESSB 5748, March 30, 2015
Members of the House Education Committee, I am Dr. Wayne Au, an Associate Professor in the School of Educational Studies at the University of Washington Bothell. I am here today as an individual citizen, a parent of a future public school student, and a nationally and internationally known scholar with expertise in education policy and high-stakes testing. I am testifying today to share my concern about using standardized test scores toevaluate teacher performance. The logic of using test scores to evaluate teachers seems like commonsense: A teacher teaches, a student learns, a test is given, and the test score shows the effectiveness of teaching. However, this logic falls apart in the face of research. For instance, using test scores in teacher evaluation has produced large statistical errors. Based on a single year’s scores, one major study by the U.S. Department of Education found a 1 in 3 chance of mislabeling a proficient teacher as not proficient.[1] Other research has foundwild, year-to-year swings in teacher ratings based on test scores, where teachers highly rated one year dropped to the bottom, and teachers poorly rated shot to the top, the next year. This inconsistency suggests that the tests are measuring the changing, year-to-yeardemographics of students as opposed to measuring the ongoing effectiveness of teachers.[2]Finally, we have known for decades that non-school, poverty-related factors like lack of adequate healthcare, food insecurity, and housing insecurity, account for up to 70% of an individual student’s test score. The impact of teachers on test scores pales in comparison to the impact of such broader social and economic issues.[3] Given problems such as these,[4]leading educational researchers[5] and the American Statistical Association[6] havewarned against using standardized test scores to evaluate teachers. Unfortunately the U.S. Department of Education refuses to pay attention to these experts and continues to push such a fundamentally wrong-headed policy. The State of Washington should not follow their lead. Thank you.
