This is one of the best columns I have ever read by Marc Tucker.

He writes what everyone knows other than President Obama, Secretary Duncan, Governor Cuomo, and a few dozen other governors.

Tucker writes that test-based accountability is a failed policy.

“In my last blog, I pointed to the data that shows that, after 10 years of federal education policies based on test-based accountability, there has been no perceptible improvement in student performance among high school students (which, when you get right down to it, is what really matters) as a whole, or when the data are broken down by different groupings of disadvantaged students. There is little doubt—whether test-based accountability is being used to hold schools accountable or individual teachers—that it has failed to improve student performance.

“That should be reason enough to abandon it. But it is not. The damage that test-based accountability has done goes far deeper than a missed opportunity to improve student achievement. It is doing untold damage to the profession of teaching.

“Anyone who has been paying attention has by now seen many videos of widely admired teachers explaining to the camera why they are giving up teaching and why they would not recommend that their children, nieces or nephews choose teaching as their career. The narrative is always the same. They have loved teaching because it has enabled them to make a real difference, one child at a time. They talk about the children consumed by anger or alienation who they reached with kindness and care and whose life was turned around as a result, and the student who discovered in music something they could do well and take pride in, and another whose interest in science was kindled by field trips that departed from the official curriculum and included material not on the test but which enabled the student to see the wonder of science all around her and who went on to win the country science fair and another who sat silent in class and never turned in any homework until the teacher was able to unwind the nature of the problem in a horribly abusive family situation and get social services to rescue the student….

“These are teachers whose entire professional life has been marked by pride in their work and their ability to use their accumulating professional experience to make large differences in the lives of their students. But they cannot take it anymore. It makes no sense at all to them to measure all their accomplishments by student scores on tests of low-level English and mathematics literacy when they want them to understand where political liberty came from and what it takes to sustain it. Reducing everything they have tried to do for their students to scores on low-level tests of two subjects makes a mockery of their work. Using the scores from this very narrow slice of student accomplishment to mark their school with an A or B or C or, worst of all, a D lumps together the school just beginning to turn around under a brilliant new leader with the school on the other side of town that has been sliding downhill under listless leadership for years….They know that the value-added methods now in vogue can label an individual teacher excellent one year and a dunce the next….

“Test-based accountability and teacher evaluation systems are not neutral in their effect. It is not simply that they fail to improve student performance. Their pernicious effect is to create an environment that could not be better calculated to drive the best practitioners out of teaching and to prevent the most promising young people from entering it. If we want broad improvement in student performance and we want to close the gap between disadvantaged students and the majority of our students, then we will abandon test-based accountability and teacher evaluation as key drivers of our education reform program.”

Read the whole article, including the parts I had to leave out, since I am not allowed to copy the article in full.
.it is a bracing dose of common sense.
