Raising smart kids is difficult in and of itself, but what about raising successful ones? How exactly do you do that? Read on to find out what science says parents of successful children have in common--and see if you can integrate any of these habits into your own parenting ways.

1. Keep expectations high

Although it may seem like common sense for parents to simply want the best for their children, it turns out that the act of keeping high expectations--and holding children responsible for them--is crucial to routinely successful behavior on the child's end.

In a national survey of 6,600 of children born in 2001, 96% of the kids who did the best on standardized tests were expected to go to college by their parents. However, only 57% of those who did the worst on these tests were expected to go to college by their parents.

2. Maintain healthy relationships with one another

It can seem like a no-brainer, but you'd be surprised how many parents have unhealthy relationships with their children. According to a University of Illinois study, children who come from high-conflict families tend to have lower performance rates overall than those with peaceful familial environments.

Interestingly enough, the study also sheds light on the fact that it doesn't matter whether the parents were divorced or still intact; what mattered most was the setting at home, and how much each member of it respected one another.

3. Push effort, not perfect results

While achieving the best results may be important to many parents, it ultimately pays to encourage trying something and failing, over avoiding attempting altogether. Stanford professor Carol Dweck differentiates what's so important between a "fixed mindset" and a "growth" one.

Those who possess "fixed mindsets" assume that things out of our control predetermine all our character, intelligence, and traits. "Growth mindsets," however, flourish under challenge. These are the children who end up improving most since they see every obstacle as an opportunity to grow and better themselves--not one to fail.
