A substantial literature documents large variation in teacher effectiveness at raising student achievement, providing motivation to identify highly effective and ineffective teachers early in their careers. Using data from New York City public schools, we estimate whether subjective evaluations of teacher effectiveness have predictive power for the achievement gains made by teachers’ future students. We find that these subjective evaluations have substantial power, comparable with and complementary to objective measures of teacher effectiveness taken from a teacher’s first year in the classroom.

Standardized tests have much in common with French fries. Both of them differ in composition as well as quality. French fries are available in numerous incarnations, including straight, curly, skins-on, skins-off, and, in recent years, with sweet potatoes. Regarding quality, of course, the taste of French fries can range substantially – from sublime to soggy. It’s really the same with standardized tests.

Take the No Child Left Behind Act, for instance, a federal accountability law requiring scads of standardized tests to be used in evaluating schools. Do you know that almost all of the standardized tests now being employed to judge school quality are unable to distinguish between well taught and badly taught students?

all schools – kindergarten through college – should employ exit exams allowing us to determine what students have actually learned. We owe it to our students to make sure that they’ve been properly taught.

Then there are the questions of what to do with the results. I have actually sat through an extended discussion of how we could use regression analysis to parse out the contribution different teachers made to a group of students’ performance on a set of standardized tests. The answer was, yes it was possible, and could in fact be used to award merit pay increases. But nobody left the room feeling very comfortable that there would be any gain in what we knew made for good teaching.

educators have a strong incentive to “teach to the test.” In this case, that means teaching low level skills at the expense of the more demanding material that everyone says students need to master in today’s complicated world.

But is it fair to give students what amounts to a counterfeit passport to college or work? And do such tests spur high school teachers and principals to aim high with their students? To both questions, the answer is, “No.” In most states today, high school exit tests serve the same role as the standardized tests mandated by NCLB: they try to jack up the floor of student achievement in the nation’s schools. The best high school exit tests would be end-of-course exams akin to the “comprehensive” exams that many colleges and universities require students to pass in their majors before graduation – tests, that is, that would raise the ceiling of student achievement.

High-stakes testing has narrowed and dumbed down curricula; eliminated time spent on untested subjects like social studies, art, and even recess; turned classrooms into little more than test preparation centers; reduced high school graduation rates; and driven good teachers from the profession. Those are all reasons why FairTest and other experts advocate a sharp reduction in public school standardized testing and a halt to exit exams.
