Known as shadow education (SE) in literature, private tutoring has been used as a major means to achieve academic excellence in Asian countries or regions including Japan, South Korea, Singapore, mainland China, Hong Kong (China) and Taiwan (China) (see Introduction by Kim & Jung). Responding to this social reality, this book explores the academic achievement of students in East Asia through in-depth scrutiny of the role private tutoring plays in students' learning processes.The volume offers insights into the functions, meanings and values of SE within the broader historical, cultural, economic and educational contexts. It innovatively theorizes East Asian students as nomads (p. 78) across different learning spaces and SE as a phenomenon of a transboundary learning culture, variables of academic success and means of learning capital. The text establishes a balanced image between the stereotypical identity of SE as catalyst for inequality and the integral role SE plays in the educational ecosystem, that cannot be neglected in the discussion of education performance, equality and policy. By doing so, Kim and Jung (2022) argue that, for the first time in the field of educational studies, all research should consider the importance of SE as a new norm in contemporary societies.The major purpose of the book is to explore the influence of SE on academic performance (Part 1-3), learning culture (Part 1, Part 3), and East Asian societies in general (Part 3). Thirteen chapters centre on three distinct yet overlapping themes entitled: (Part 1) Shadow Education, Transboundary Learning Culture and Academic Success, (Part 2) Top Tiers of PISA: World Class Learners and Use of Shadow Education and (Part 3) Shadow Curriculum, Race for Academic Success and Winner-takes-it-all. Part one retheorizes SE to refresh the discourse on students' academic achievement (Chapter 1 by Kim & Jung; Chapter 2 by Kim, McVey & Jung), students' identities (Chapter 4 by Min & Jo) and the learning culture in East Asian societies (Chapter 3 by Kim, Jo, & Jung). The theorization touches upon the extant limitations of research methods and perspectives on SE, which goes beyond the dominant discourse on private tutoring as a reproducer of inequality (see Chapter 13 by Entrich & Lauterbach). The first four chapters promote the positive image of SE and East Asian students as active learners who creatively use various tutoring to support their learning. Therefore, Kim and Jung (2022) justify SE as a rigorous learning space to support students' academic performance (Chapter 1). Part two focuses on the top tiers of PISA tests
