Using data from the Programme for International Student Assessment (PISA), patterns of parental involvement were examined in selected OECD countries. The findings showed that, irrespective of educational qualifications, parents were frequently involved in their children's learning at the start of primary school and at age 15. Cross-national analyses showed that a high percentage of parents were frequently involved in various ways with their children's learning, with some OECD countries showing parental involvement to be very common. Less instrumental, more subtle forms of parental involvement such as parent-child conversations about topical social issues emerged as the strongest predictor for continuing parental literacy support at age 15. These findings have important implications for understanding patterns and forms of parenting and for guiding family policy to consider cultural, economic and educational explanations about the nature of parental involvement in children's education.
