There is a saying that American students are the most tested, and the least examined, of any in the world. We test students in the U.S. far more than any other nation, in the mistaken belief that testing produces greater learning: since No Child Left Behind was passed in 2002, public schools have been required to test every child every year in third through eighth grade. Students face additional tests in high school, almost all of them primarily multiple-choice.
Policymakers have tied more and more decisions to test scores. They factor into whether students will be promoted or graduated, how much teachers will be paid, and whether they will remain employed, whether schools will receive rewards or sanctions–including, with recent policies, whether their staffs will be fired or whether they will be closed entirely. Recent cheating scandals, like those in Atlanta and Washington DC, are one result of this pressure. But cheating is rare, and there are far more wide-reaching negative consequences of this obsession.
Rather than improving education, the current desire to attach scores from a burgeoning battery of tests to student, teacher, and school decisions actually undermines the quality of education in at least three ways.
First, it dumbs down the curriculum: studies have found that schools, especially in low-income communities, are reducing or even eliminating instruction in non-tested subjects like science, social studies, and the arts. Without a well-rounded curriculum, children lack the knowledge needed to understand complex texts, to investigate and understand the world around them, and to create–the American advantage that is fast slipping away from us. High-stakes testing also drives multiple-choice instruction. As classroom activities increasingly mimic the tests, students are doing less and less of the things colleges and employers want more of: researching, writing, using technology, explaining and defending their ideas, collaborating, and solving complex problems.
Second, punishing schools for low scores creates incentives for schools to keep out and push out students who score poorly on tests. In a market-based system of school choice that is managed by test scores, schools work to get and keep the easiest students and to get rid of those who struggle to learn. Evidence shows that some charter schools avoid admitting poor students and those with disabilities, while sending the most problematic kids back to the public schools. However, district-run public schools can also boost scores by pushing out low-achieving students. This occurs through disciplinary actions, grade retention, and counseling that encourages students to transfer or drop out. Although scores go up, our children and our society suffer from the growing school-to-prison pipeline.
