YMMV, but only in the last two years of high school do I recall these five-paragraph essays being a substantial part of classes. We certainly did them from time-to-time before that, but we also did a lot of other writing of many different forms, and in the last year or two also did a couple "research papers" (in the classic sense, not in the grad student moving a field forward sense).
