The relationship between self-concept and academic achievement that is commonly cited has primarily been found in studies of students from Western countries with individualistic societies. Thus, this relationship may not be evident among students from non-Western countries, which are thought to largely adopt collectivist cultural values and behaviors that are inconsistent with the way that students from individualist nations perceive and evaluate their academic functioning. This lack of clarity motivates the present scoping review about the relationship between self-concept and academic achievement among students from collectivist countries who study in elementary, secondary, and post-secondary schools. A final review of 27 empirical articles involving student populations across educational levels and from several collectivist countries provided support for the same general relationship between self-concept and academic achievement that has been found in Western countries. Accordingly, the development of a favorable self-concept was associated with greater academic achievement. In some cases, this relationship was dependent on self-concept and academic achievement being measured in the context of a school-related discipline and on the time interval between the examination of both variables. Our findings provide insight into pathways to academic success that are effective across cultures, and we offer considerations for successful academic self-concept interventions for collectivist students.
