The present study compared the contribution of familial cultural capital to the reading achievement of 116,508 15-year-old students who participated in PISA 2012 in six Confucian heritage cultures (CHCs) and nine non-CHCs with comparable educational and economic development. The different states of cultural capital examined comprised institutionalised (maternal, paternal education) and objectified (educational, cultural resources) indicators. Results showed that: (1) cultural capital levels were lower in CHCs (vis-à-vis non-CHCs); (2) cultural capital was generally positively related to student achievement in CHCs and non-CHCs; (3) the relationships between all cultural capital indicators, except educational resources, and achievement were weaker in CHCs than non-CHCs; and (4) objectified (vis-à-vis institutionalised) cultural capital was more strongly associated with achievement in CHCs. These results suggest that the stronger sociocultural emphasis on education in CHCs may have moderated cultural capital effects on student achievement and enabled more students to succeed academically.
