Denise Clark Pope, a professor at Stanford University, national expert on causes of stress for high school kids, reports that nationally high school students spend less than an hour nightly doing homework.

But, her latest research on close to 4300 upper middle-class communities, in 4 public and 6 private schools, found an average nightly workload of more than 3 hours. Such time spent on homework is associated with greater stress, more compromised health, less time for family, extracurricular activities and a greater likelihood of dropping hobbies and activities.
