Our school (private) doesn’t rank. It also doesn’t weight classes. And I think, contrary to @MWolf 's school, only one student has gotten a 4.0 on a 4 point scale in the last 5 years.
Students are asked to push themselves and take risks. This is a hard sell when there is a big penalty for finding that learning edge. And realistically, how do you rank two kids with vastly different talents? The kids who are doing CalcBC as freshmen are generally not the ones getting a novel published.
Of course, part of the reason this works is that the school isn’t trying to differentiate between kids with vastly different rigor and drive. It’s harder in a school in which there are gen ED classes at one end of the spectrum and AP classes at the other. In our LPS, ranking has had some perverse outcomes – kids avoid latin because it doesn’t have an honors level while Spanish does, for example.
Our school does send detailed information on the general range of grades in each class, who takes them, etc.
