Standardized testing for higher education has been much in the news in the US over the last few years. In the wake of the Spellings Commission, the clear intent of the Department of Education's (USDOE) position in negotiated rulemaking in 2007 was to mandate its use in accreditation. Standardized testing is also a central feature of the Voluntary System of Accountability (VSA), implemented by the Association of Public Land Grant Universities (APLU) and the American Association of State Colleges and Universities (AASCU). And a standardized instrument--the Collegiate Learning Assessment (CLA)--generated most of the data used in Arum and Roksa's popular indictment of collegiate learning, "Academically Adrift." In a rapidly "flattening" world, it should therefore come as no surprise that the phenomenon has gone global. This article discusses the Assessment of Higher Education Learning Outcomes (AHELO), a 17-country initiative of the Organisation for Economic Cooperation and Development (OECD) aimed at assessing student knowledge and abilities in higher education.
