Since the 2001 passage of the No Child Left Behind Act (NCLB), test-based accountability has been an organizing principle--perhaps "the" organizing principle--of efforts to improve American schools. But lately, accountability has been under fire from many critics, including Common Core opponents and those calling for more multifaceted…

Education standards do not flop spectacularly. Their failure gives rise to nothing like the black-and-white films of early aeronautical experiments: no missiles exploding on launch pads or planes tumbling from the sky. But 10 years after 46 of the 50 states adopted the Common Core standards, the lack of evidence that they have improved student…

The 10th anniversary of Common Core's launch offers the opportunity to take stock of the impact these nearly national standards have had on student learning, as well as their future prospects. In this article, Morgan Polikoff shares his view that the standards movement in general, and Common Core in particular, have achieved all they are going to…

Linking IEA's international reading assessments across 40 years is an interesting endeavor from several perspectives. Being able to examine trends in reading achievement at the 4th grade over such a long period and relate these to policy changes during that time span is an attractive idea. However, this work brings to the fore many thorny issues…

The Common Core State Standards, released in 2010, were rapidly adopted by more than 40 states. Champions maintained that these rigorous standards would transform American education, but the initiative went on to encounter a bumpy path. A decade on, what are we to make of this ambitious effort? What kind of impact, if any, has it had on the…

This Center for American Progress report examines whether states' adoption of standards-based policies predicts low-income students' NAEP achievement trends in fourth and eighth grade math and reading throughout the 2003-2013 decade. The report claims to analyze changes across five separate two-year intervals, but it only reports findings for…

This paper is a response on the topic of school reform efforts being promoted by Bill Gates and other prominent education policy advocates. Last week, Microsoft Chairman Bill Gates published an op-ed in the Washington Post, "How Teacher Development could Revolutionize our Schools," proposing that American public schools should do a…

Every two years the National Assessment of Educational Progress (NAEP), "the Nation's Report Card," reports the nation's average reading and math scores in grades 4 and 8. Despite the strong focus on reading under the 2001 No Child Left Behind law, the recent 2009 reading scores were not statistically different from those of 2007, which…

For a decade, at least since the passage of No Child Left Behind, the nation's foremost education goal has been to erase achievement "gaps" in which African American, Latino, and low-income students dramatically lag behind their peers. This emphasis has enjoyed broad support through the Bush and Obama administrations, and from major…

More than seven years ago, President George W. Bush signed No Child Left Behind (NCLB) into law. Sweeping calls for testing, intervening in persistently low-performing schools, and policing teacher quality made it the most ambitious legislation on K-12 schooling in American history. The law, due for congressional reauthorization in 2007, still…
