Extensive research has suggested that there is a large rural-urban student achievement gap in China.However,less is known about the effects of family background and parental expectations on student achievement.Using a large representative sample of Chinese eighth graders,this study examines these relationships.We find that:(1) Rather than a rural/urban hukou (household registration system) type,it is variation in family background,especially family socioeconomic status (SES),which plays a significant role in student achievement;(2) although factors of family background show different patterns of influence on Chinese,mathematics,and English achievement,maternal education and home educational resources are significantly positive predictors consistently across three subjects;(3) parental expectations are significantly and positively associated with Chinese,mathematics,and English achievement.
