AbstractThe effects of academic achievement may extend beyond economic success to influence social functioning, including future parenting. To evaluate whether adolescent academic achievement forecasts future parenting (both positive and negative) and the family home environment of parents. We used prospectively gathered intergenerational data from a population‐based birth cohort born in 1972/1973 in Dunedin, New Zealand, including data from Generation 1 (parents of the birth cohort), the birth cohort (Generation 2; G2), and G2's children (Generation 3). Adolescent academic achievement in G2 was used to predict observed and reported parenting outcomes when offspring (G3) were aged 3 years after controlling for a range of covariates, including G2's adolescent wellbeing, early childhood socioeconomic status (collected from G1), and G2's age at child's birth. We also evaluated 2‐way interactions between academic achievement and G2 parent sex, G3 child behaviour, and G2 adolescent wellbeing. Greater G2 academic achievement, net of controls, predicted more positive and less negative parenting (for mothers only), and a more positive home environment. For the home environment outcome, the effect of adolescent academic achievement was moderated by wellbeing. Adolescent academic achievement may positively influence parenting behaviour and the quality of the home environment.
