The school year is winding down, but one faction within the world of education is ratcheting up: the anti-testing movement. More parents are pulling their kids out of end-of-year math and literacy assessments. More teachers and administrators are speaking up against testing–like the group of school district superintendents in Georgia who are calling on the state legislature to reconsider its test-based accountability system. And a national resolution condemning testing has now attracted the endorsements of more than 300 organizations and 8,500 individuals. Standardized testing is “an inadequate and often unreliable measure of both student learning and educator effectiveness,” the resolution reads in part, and “the over-reliance on high-stakes standardized testing in state and federal accountability programs is undermining educational quality and equity in U.S. public schools.”
