Grit is a trait that describes the drive to succeed above and beyond natural intelligence. While grit has been associated with positive academic outcomes, few researchers have investigated the predictors of grit, such as parenting. We examined the influence of parenting on grit and academic success in 226 college students. Results indicated that overparenting and parental acceptance and involvement were significantly related to grit and grit was found to have a significant predictive relationship with academic success. Further, grit mediated the relationship between overparenting and academic success.
