PISA 2015 Results (Volume I) Excellence and Equity in Education

OECD's triennial international survey, PISA (Programme for International Student Assessment), aims to evaluate education systems worldwide by testing the skills and knowledge of 15-year-old students, examining not just what students know, but what they can do with what they know. In PISA 2015, the survey was carried out for the first time in all 28 EU Member States in the same year, among 72 countries and economies worldwide, the results showing educators and policy makers the quality, equity, and efficiency of school systems and student learning outcomes achieved elsewhere, allowing them to learn from the policies and practices applied in other countries. The 2015 survey had a special focus on science performance but also assessed students' skills in mathematics, reading, collaborative problem solving and financial literacy
