Has the achievement of U.S. students improved over the past half century? Have gaps between racial, ethnic, and socioeconomic groups widened or narrowed? These and similar questions provoke near-constant conversation. But answers are uncertain, partly because research to date has yielded inconsistent findings. In this article, the authors bring…

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…

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…

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…

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…

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…

Ninety-five percent of students at Redwood City's Hoover School, in San Mateo County, California, come from low-income and working-class Latino families, and nearly all start school as English language learners (ELLs). The elementary and middle school piloted the Sobrato Early Academic Language (SEAL) program in 2009 in hopes of raising reading…

When Daniel Patrick Moynihan raised the issue of family structure half a century ago, his concern was the increase in black families headed by women. Since then, the share of children raised in single-parent families in the United States has grown across racial and ethnic groups and with it evidence regarding the impact of family structure on…

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…

This article describes the grim sentiments from the U.S. Secretary of Education, Arne Duncan, when reviewing the poor results from the U.S. performance on the 2012 Program for International Student Assessment (PISA). He noted a straightforward and stark picture of educational stagnation--that fifteen-year-olds in the U.S. today are average in…

Since their start in Houston in 1994, KIPP (Knowledge Is Power Program) charter schools have been the most celebrated of the No Excuses schools. Employing strict discipline, an extended school day and year, and carefully selected teachers, No Excuses schools move disadvantaged students who start behind their peers academically up to and above…

Policymakers nationwide continue to wrestle with a basic question: At what grade level should students move to a new school? In the most common grade configuration in American school districts, public school students make two school transitions, entering a middle school in grade 6 or 7 and a high school in grade 9. This pattern reflects the…

In recent years, a consensus has emerged among researchers that teacher quality matters enormously for student performance. Students taught by more-effective teachers learn substantially more over the course of the year than students taught by less-effective teachers. Yet little is known about what makes for a more-effective teacher. Most research…
