For the past four years, the Center on Education Policy (CEP), an independent nonprofit research and advocacy organization, has been conducting a comprehensive and continuous review of NCLB, producing the annual reports contained in the series From the Capital to the Classroom (all of which are available at www.cep-dc.org) as well as numerous papers on specific issues related to the law. State and local officials have identified the testing and accountability requirements for students with disabilities and for students learning English as troublesome, and other requirements-such as the one to offer a choice of another public school to students in schools needing improvement-have caused administrative burdens with little evidence that they have raised student achievement.
