Globalisation refers to the idea that in recent decades the world has become more interconnected; the idea of a "global village". This is said to have happened economically (through transnational corporations and global institutions like the World Bank), politically, socially and culturally. Modern technology means that communication and travel around the world is easier than ever. Education has been impacted by globalisation as schools and education systems now compete on a global league table rather than just local or national competition. For example, the Organisation for Economic Co-operation and Development publish a yearly report which details where each country falls within a global league table.
