Creativity, innovation, collaboration, communication, and human connection are widely recognised as essential outcomes of education. Yet each year, more students quietly step away from the very subjects most explicitly designed to develop those qualities.Within the International Baccalaureate (IB) Diploma Programme (DP), participation in arts subjects has been declining for more than a decade. Nearly half of all IB World Schools offering the DP do not offer a single arts subject. This is not a crisis of artistic value. It is a crisis of institutional signals: the timetables, policies, counselling conversations, and assumptions that shape what students believe matters most.Drawing on award-winning doctoral research conducted across IB World Schools on four continents, alongside more than a decade working with schools internationally and within the International Baccalaureate, this book explores the forces shaping arts participation and provides practical, evidence-informed strategies for increasing uptake. This is not a book about waiting for curriculum reform or additional funding. It is a book about what schools can do now.The arts are not losing because the argument against them is strong. They are losing because the argument for them has been made too quietly, by too few people, for too long. This book is about changing that.
