International education systems refer to the various frameworks and structures used by countries to deliver education to their citizens. These systems can differ significantly in terms of curriculum, teaching methods, and assessment practices. For example, some countries follow the International Baccalaureate program, while others may adhere to national standards like the Common Core in the United States. These systems aim to prepare students for a globalized world by promoting skills such as critical thinking and cultural awareness. Many countries also participate in international assessments, such as the PISA tests, to evaluate and compare educational outcomes on a global scale.
