I don't know if you're referring to pre-match or not. But programs have no way of knowing where you rank them BEFORE the match. In fact, programs put their rank lists in 1 month (usually sooner) than your rank list is due. In fact, late february/early march is the time when you may get contacted by program directors/chairs via mail or phone. For instance, I got a call from a particular program chair at the end of February basically saying that "our rank list has been submitted, and we ranked you in a favorable position." So don't worry about programs finding out where you ranked them, UNLESS you tell someone on the trail that you're gonna rank them No. 1, they in turn rank you at the top and you end up going somewhere else. Then you could be in trouble. The world of ortho is a very small world.
