Benchmarking countries

Chapter 9 addresses the benchmarking of countries. Although Chapter 5 summarises the mastery levels across countries, equally weighting the countries because of sample size differences, the current chapter discusses the results by country without disclosing the nationalities. The countries are labelled A through E for anonymity. The data presented include only countries that tested entering and exiting students, which are Chile, Finland, Mexico, the United Kingdom and the United States. Italy tested exiting students only and, therefore, is not included in these results.
