Understanding the Interaction Between High-Stakes Graduation Tests and English Learners

Background/Context: The prevailing theory of action underlying No Child Left Behind’s high-stakes testing and accountability ratings is that schools and students held accountable to these measures will automatically increase educational output as educators try harder, schools will adopt more effective methods, and students will learn more. In Texas, the centerpiece of high school accountability is the pressure to improve exit test scores, a battery of minimum competency exams that students have to pass to graduate from high school. Despite the theory underlying accountability, it is unknown whether policies that reward and sanction schools and students based on high-stakes tests improve English learner (EL) student outcomes over the long term.
