Comparing PIRLS and PISA with NAEP in Reading, Mathematics, and Science

Reporting results to provide a comprehensive picture of how U.S. students perform in key subject areas is one of the objectives of the National Center for Education Statistics (NCES). In the United States, nationally representative data on student achievement come primarily from two sources: the National Assessment of Educational Progress (NAEP)—also known as the “Nation’s Report Card”—and the United States’ participation in international assessments, such as the Progress in International Reading Literacy Study (PIRLS) and the Program for International Student Assessment (PISA).
