Poor ranking on international test misleading about U.S. student performance, Stanford researcher finds

Jonathan Rabinovitz:

Socioeconomic inequality among U.S. students skews international comparisons of test scores, finds a new report released today by the Stanford Graduate School of Education and the Economic Policy Institute. When differences in countries' social class compositions are adequately taken into account, the performance of U.S. students in relation to students in other countries improves markedly.

An accurate comparison of nations' test scores must include a look at the social class characteristics of the students who take the test in each country, says Stanford education Professor Martin Carnoy.

The report, What do international tests really show about U.S. student performance?, also details how errors in selecting sample populations of test-takers and arbitrary choices regarding test content contribute to results that appear to show U.S. students lagging.

In conducting the research, report co-authors Martin Carnoy, a professor of education at Stanford, and Richard Rothstein, a research associate at the Economic Policy Institute, examined adolescent reading and mathematics results from four test series over the last decade, sorting scores by social class for the Program on International Student Assessment (PISA), Trends in International Mathematics and Science Study (TIMSS), and two forms of the domestic National Assessment of Educational Progress (NAEP).

Based on their analysis, the co-authors found that average U.S. scores in reading and math on the PISA are low partly because a disproportionately greater share of U.S. students comes from disadvantaged social class groups, whose performance is relatively low in every country.
