My brother had this opportunity in a public elementary school. "Mrs. F" was the teacher for the same group of students for 2 or 3 consecutive years. It was very much an experiment, but by all accounts it was a success. I recognize that this is just an anecdote, and there is the potential to get stuck with a bad teacher as other commenters have pointed out, but at least in his case, it was an overwhelmingly positive experience. I wish that I'd had the same opportunity. The class formed an especially close bond with each other and the teacher, and that led to some really unique extracurricular activities. At that age, parents are often still very involved in their children's education, and Mrs. F was able to form relationships with the parents as well, allowing the class and their families to go on special weekend camping trips, visit museums, participate in science competitions, among other things. Years later, many of them still keep in touch, and I think just about everyone involved went on to higher education, many at very prestigious schools.
