This peer-reviewed academic yearbook stems from the inaugural meeting of the newly formed UNESCO UNITWIN network on Arts Education Research for Cultural Diversity and Sustainable Development, held at the National Institute of Education, Singapore in April 2017. It presents international scholarly perspectives on issues related to arts education and cultural diversity in terms of: i) national and international policies; ii) terms, concepts and vocabularies; iii) current and ongoing research; and iv) best practices.  The UNESCO UNITWIN is an arts education research think tank that gathers and leverages original research and critical commentaries on the arts and sustainable development from UNITWIN member states and beyond (Australia, Canada, Colombia, Germany, Hong Kong, Kenya, Korea, Israel, New Zealand, Singapore, Taiwan, the Netherlands and the United States of America).
