The International Schools Theatre Association is a UK-registered charity and global arts organisation that provides transformative theatre experiences for young people and professional development for educators. While it operates globally, it is deeply embedded in the UK independent sector, particularly among schools offering the International Baccalaureate (IB). ISTA is the official provider of IB Diploma Programme Theatre teacher training. It focuses on fostering "internationally minded" students through collaboration, diversity, and the ensemble method, rather than competition.
