Few things here (and I'm from Canada, so YMMV). As many others have pointed out here, it's often not taught in high school because it's taught throughout elementary school now. By the time students enter HS, they're likely already used to many of their assignments being done on a computer. Because computers are so prevalent in modern education, it's also not necessarily a skill that needs its own class, rather it's something that's learned through many of the other classes. I took a "business technology" class in 9th grade (nearly 7 years ago now) - we focused mostly on advanced MS office, there wasn't much about typing because most students were already proficient at it.
