“…Although SE was long viewed as an exotic East Asian “cultural oddity” (Baker, 2020), it is now a substantial topic in comparative sociology and education (Zhang and Bray, 2020). With good reason, SE has become a major global phenomenon, a part of mass schooling in many societies and probably the most significant international trend in education in the 21st century (Bray, 2017; Byun et al, 2018; Entrich, 2018; Gordon Győri, 2020; Kim and Jung, 2019; Kobakhidze and Suter, 2020; Mori and Baker, 2010; Šťastný and Kobakhidze, 2020; Wiseman, 2013). Against the background of the observed worldwide increase in the participation in both major forms of SE in recent decades (Bray, 2017; Park et al, 2016), the often-reported tight linkage between socioeconomic status (SES), SE investment, and academic outcomes of students indicates major implications for educational opportunities and inequalities in educational attainment.…”
