does the fate of the nation rest on how well 9- and 13-year-olds bubble in answer sheets? I don’t think so. Neither does British economist, S. J. Prais. We look at the test scores and worry about the nation’s economic performance. Prais looks at the economic performance and worries about the validity of the test scores: “That the United States, the world’s top economic performing country, was found to have school attainments that are only middling casts fundamental doubts about the value and approach of these [international assessments].”
