The Organisation for Economic Co-Operation and Development’s (OECD) report Education at a Glance 2014: OECD Indicators was released on September 9. The report draws on student test results, government spending, employment statistics and other metrics in order to explore the relationship between education and social progress. For example, only 30% of adults in the United States who are no longer in school have completed more education than their parents. The report covers a wide range of topics, such as how many three-year-olds are attending preschool around the world to how many adults without a high school education are faring in the workplace and also examines the relationship between the recession, countries’ Gross Domestic Product, and public spending on educational institutions.
