With the debut of common assessments less than two years away, states and districts are worried about the accountability systems that hinge on those tests. A growing chorus of policy groups is urging more flexibility in how states evaluate teachers, label schools, and enforce other high-stakes consequences during what's likely to be a messy transition. Position papers from a range of organizations seek to stake out turf on the delicate question of how to postpone or temporarily ease some rules without abandoning accountability, at a time when the new, tougher assessments are projected to send test scores--at least at first--into a nose dive.
