"A report released Tuesday aims to debunk claims that the United States lags substantially behind the international competition in education. The study, released by the Stanford Graduate School of Education and the Economic Policy Institute, argues that looking only at the United States’ average score on international exams is problematic and can lead to unwarranted policy conclusions.
By disaggregating the data of the Programme for International Student Assessment (PISA), researchers concluded that U.S. students fared better on the exam in 2009 than most had originally believed. In particular, low-income students appear to have gained ground on disadvantaged students in other countries.
