The present study examined the relationship between executive function and early achievement, and the mediating role of approaches to learning on the association. A total of 245 children aged between three and six years of age were recruited from 6 kindergartens in Shanghai. Children were administered executive function by the head-toes-knees-shoulders(HTKS) task, and early achievement by the language and early literacy and cognitive development subtests of the East Asia-Pacific Early Child Development Scales(EAP-ECDS) in individual sessions. Their development of approaches to learning was rated by their teachers through the revised Child Behavior Rating Scale(CBRS). The results showed that executive function was significantly correlated with approaches to learning and early achievement in language and literacy, and mathematics. Furthermore, approaches to learning mediated the relationship between executive function and early mathematics.
