As states have passed laws establishing charter schools, advocates have carefully tracked and analyzed state policies and enrollments to compare charter school growth, demand, and access across the United States. But to date, there have been no comparisons of charter school performance across states based on student achievement adjusting for…

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…

As an early Common Core booster, Michael Petrilli had hoped that by now--10 years after most states adopted the standards--the nation's schools would have logged tangible improvements in teaching and learning that resulted in higher student achievement. In this article, Petrilli reviews what Common Core is and discusses the work ahead that is…

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…

Income inequality has soared in the United States over the past half century. Has educational inequality increased alongside, in lockstep? Despite the topic's importance, surprisingly little scholarship has focused on long-term changes in the size of the achievement gap between students from higher and lower socioeconomic backgrounds. The authors'…

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 spite of Tea Party criticism, union skepticism, and anti-testing outcries, the campaign to implement Common Core State Standards (otherwise known as Common Core) has achieved phenomenal success in statehouses across the country. Since 2011, 45 states have raised their standards for student proficiency in reading and math, with the greatest…

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…

Much ado has been made about setting high standards over the past year. Current conversations about creating a common national standard largely focus on the substantive curriculum to be taught at various grade levels. Even more important is each state's expectations for student performance with respect to the curriculum, as expressed through its…

This article reports that special interest groups opposed to charter schools and high-stakes testing have hijacked Massachusetts's once-independent board of education and stand poised to water down the Massachusetts Comprehensive Assessment System (MCAS) tests and the accountability system they support. President Barack Obama and Massachusetts…

According to the National Assessment of Educational Progress (NAEP), the average 17-year-old today is no more proficient at reading or mathematics than his counterpart in 1970. Some progress has been made by 9- and 13-year-olds, but the gains evaporate by the time these students reach the end of their K-12 experience. The average 17-year-old…

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…
