From the Washington Post:
High school teachers often try — sometimes to no avail– to convince students that how well they do in school will matter later in life.
Now they have data to prove it. A report published Monday in the Eastern Economic Journal by researchers from the University of Miami found that a person’s grade-point average in high school not only indicates the person’s chances of getting into college and whether he or she will finish college or graduate school. It could also be an indicator of how much that person will earn later in life.
