Over the past two decades, a spate of studies has examined the cultural beliefs that shape Asian-American parenting, and their effect on kids’ learning. They describe a style of parental involvement that results in Asian-American kids spending more time studying than other kids.

One study, for example, found that Asian-American 11th-graders studied six hours more per week than their white peers. Another found that in 2007, more than two-thirds of Asian-American high school students did homework five or more days a week, while only about 40 percent of white and Hispanic kids, and less than a third of African-American students, did so. According to other research, Asian-American kids devote less time to chores, part-time jobs and dating than other kids.
