So UVA still maintains class rank, but it's internal rank only. It's used to hand out awards at the end of second year (top person in each basic science class), and for Junior AOA nomination (because you have to be in the top 25% to qualify for AOA), but we also use other things for AOA nomination--during transition week into third year, the class actually nominates like 10 people each that they believe fulfill the goals of AOA. Step 1 scores, AFAIK, do not factor into AOA nomination here. Senior AOA, the same thing happens, but third year grades are included in the class rank determination.
The rank is not mentioned anywhere in our Dean's letter, even by ambiguous language (we're allowed to read our Dean's letters). The histogram that they include for third year grades pretty much tells where you are in the class, at least for clerkships, anyway.
