Class Matters. Why Won’t We Admit It?

NYTimes | NO one seriously disputes the fact that students from disadvantaged households perform less well in school, on average, than their peers from more advantaged backgrounds. But rather than confront this fact of life head-on, our policy makers mistakenly continue to reason that, since they cannot change the backgrounds of students, they should focus on things they can control.

No Child Left Behind, President George W. Bush’s signature education law, did this by setting unrealistically high — and ultimately self-defeating — expectations for all schools. President Obama’s policies have concentrated on trying to make schools more “efficient” through means like judging teachers by their students’ test scores or encouraging competition by promoting the creation of charter schools. The proverbial story of the drunk looking for his keys under the lamppost comes to mind.

The Occupy movement has catalyzed rising anxiety over income inequality; we desperately need a similar reminder of the relationship between economic advantage and student performance.

The correlation has been abundantly documented, notably by the famous Coleman Report in 1966. New research by Sean F. Reardon of Stanford University traces the achievement gap between children from high- and low-income families over the last 50 years and finds that it now far exceeds the gap between white and black students.

Data from the National Assessment of Educational Progress show that more than 40 percent of the variation in average reading scores and 46 percent of the variation in average math scores across states is associated with variation in child poverty rates.

International research tells the same story. Results of the 2009 reading tests conducted by the Program for International Student Assessment show that, among 15-year-olds in the United States and the 13 countries whose students outperformed ours, students with lower economic and social status had far lower test scores than their more advantaged counterparts within every country. Can anyone credibly believe that the mediocre overall performance of American students on international tests is unrelated to the fact that one-fifth of American children live in poverty?
