Research on globalization and education involves the study of intertwined worldwide discourses, processes, and institutions affecting local educational practices and policies. The four major theoretical perspectives concerning globalization and education are world culture, world systems, postcolonial, and culturalist. The major global educational discourses are about the knowledge economy and technology, lifelong learning, global migration or brain circulation, and neoliberalism. The major institutions contributing to global educational discourses and actions are the World Bank, the Organization for Economic Cooperation and Development, the World Trade Organization, the United Nations, and UNESCO. International testing, in particular the Trends in Mathematics and Science Study (TIMSS) and Programme for International Student Assessment (PISA), and instruction in English as the language of commerce are contributing to global uniformity of national curricula. Critics of current global trends support educational alternatives that will preserve local languages and cultures, ensure progressive educational practices that will protect the poor against the rich, and protect the environment and human rights.
