TIMSS 2011 is the fifth in IEA’s series of international assessments of student achievement dedicated to improving teaching and learning in mathematics and science. A globally cooperative enterprise, TIMSS conducts comprehensive state-of the-art assessments of student achievement supported with extensive data about country, school, and classroom learning environments. There is enormous diversity among the TIMSS countries—in terms of economic development, geographical location, and population size. Fundamental to IEA’s vision is the notion that the diversity of educational philosophies, models, and approaches that characterize the world’s education systems constitute a natural laboratory in which each country can learn from the experiences of others.
