New Study: There Is NO Relationship Between International Test Scores and Economic Growth

Diane Ravitch's blog

This is the most important post you will read this month or maybe even this year. It refutes the basis of American education policy.

This is major study of the relationship between scores on PISA and economic growth. It demonstrates that there is none.

It was written by Hikaru Komatsu (Associate Professor at National Taiwan University) and Jeremy Rappleye (Associate Professor at Kyoto University, Graduate School of Education) for the Network for International Policies and Cooperation in Education and Training. The authors criticize the work of Hoover economist Eric Hanushek and demonstrate how his theories of human capital development were widely adopted by American and European organizations and became the convention wisdom.

Komatsu and Rappleye demonstrate the flaws in Hanushek’s theories, which have led to unprecedented emphasis on improving standardized test scores in many nations.

They begin by reviewing a paper published by the European Commission, based on Hanushek’s human…

    County, State and Federal Departments of Education need to read Diane Ravitch’s post over Hikauru Komatsu’s and Jeremy Rappleye’s article addressing PISA scores. For decades, American educators have had to stomach harsh criticism coming from politicians and the press over the low performance of American students on international tests.

    According to Komatsu’s and Rappleye’s study, there is no correlation between high PISA scores and economic growth, which contradicts the claims of Hanushek’s previous findings. Unfortunately, Hanushek has the ear of European countries and the United States. Unfortunately, whenever there is credible research that contradicts Hanushek’s claims, these studies go unnoticed. Ms. Ravitch raised the question as to why? Why do European and U.S. leaders ignore credible studies that undermine Hanushek’s claims? Ravitch didn’t provide any answers, but I might have some.

    Hanushek’s claims have fueled a whole sub-economy–test preparation. The testing industry is huge, and this industry has lobbyists that have an omnipotent hold over our educational and political leaders. Plus, a whole cottage industry of tutorial centers have sprouted across the United States being partly buoyed by the notion that the dismal performance of U.S. students on PISA tests is going to doom the economic prosperity of this country and our young people. The whole testing industry has too much influence over education.

    It would be very interesting for researchers to discover how much money is being donated to political and educational leaders, who hold public office, by lobbyists of the testing industry.
