The National Assessment of Educational Progress (NAEP) results have long displayed student achievement in two ways: as points on a stable vertical scale that typically runs from 0 to 300 or 500 and as the percentages of test takers whose scores reach or surpass a trio of "achievement levels." These achievement levels--dubbed…

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…

The number of charter schools grew rapidly for a quarter-century after the first charter opened its doors in 1992. But since 2016, the rate of increase has slowed. Is the pause related to a decline in charter effectiveness? To find out, the authors tracked changes in student performance at charter and district schools on the National Assessment of…

In his campaign for Mayor of New York City, Bill de Blasio positioned himself as the candidate most determined to break with the legacy of the outgoing Michael Bloomberg administration. Voters responded enthusiastically, handing de Blasio a nearly 50-point margin of victory in the November 2013 election. De Blasio, a Democrat, interpreted the win…

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…

Since No Child Left Behind (NCLB) was enacted into federal law in 2002, states have been required to test students in grades 3 through 8 and again in high school to assess math and reading achievement. The federal law also asks states to establish the performance level students must reach on the exams in order to be identified as…

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…

In a report issued in 2010, the authors found only 6 percent of U.S. students performing at the advanced level in mathematics, a percentage lower than those attained by 30 other countries. And the problem is not limited to top-performing students. In 2011, they showed that just 32 percent of 8th graders in the United States were proficient in…

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…

A major debate among education reformers over how best to reduce the achievement gap broke out during the 2008 presidential campaign. Most advocates on both sides backed Barack Obama, but they urged him to pursue different policies. The Education Equality Project (EEP) supported a continuation of accountability and other school-focused reforms.…

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…

On July 14, 2006, the U.S. Department of Education's National Center for Education Statistics (NCES) released a study that compared the performance in reading and math of 4th and 8th graders attending private and public schools. According to the NCES study, students attending private schools performed better than students attending public schools.…

It turns out that in complying with the requirements of No Child Left Behind (NCLB), some states have decided to be a whole lot more generous than others in determining whether students are proficient at math and reading. Because each state selects its own testing system and sets its own passing scores, there is no direct way to compare the…
