The relationship between academic self-concept and achievement: A multicohort-multioccasion study

► The reciprocal effects exist for both math and Chinese for the high-school students. ► The causal relationship of academic self-concepts and achievement for pre-adolescents varied depending on school subjects. ► The causal effects from academic achievement decline with age, whereas those from academic self-concepts increase with age. ► The cross-domain effect from prior achievement to subsequent academic self-concept is not strong in the unified model.
