We ran into this much more in middle school than now that the kids are in high school. Maybe it's that more kids are doing other things, maybe it's that high school is less project-oriented, maybe it's that our middle school had an overwhelming number of prima donnas per square inch. But neither of my kids (both AP/honors track, but with different teachers) has more than an hour or so of homework per night, and almost never on weekends.
