International schools are private schools that promote education in an international environment or framework. Although there is no uniform definition or criteria, international schools are usually characterised by a multinational student body and staff, multilingual instruction, curricula oriented towards global perspectives and subjects, and the promotion of concepts such as world citizenship, pluralism, and intercultural understanding;[1] most are private schools. Many international schools adopt a curriculum from programmes and organisations such as the International Baccalaureate, Edexcel, Cambridge International Education, FOBISIA, International Primary Curriculum, or Advanced Placement. International schools often follow a curriculum different from the host country, catering mainly to foreign students, such as members of expatriate communities, international businesses or organisations, diplomatic missions, or missionary programmes. Admission is sometimes open to local students to provide qualifications for employment or higher education in a foreign country, offer high-level language instruction, and/or foster cultural and global awareness.[2]
