Thoughts on systems such as Naviance/Other Are they good indicators?

Yeah - like Harvard and Stanford, no surprise, those accepted actually go. But a kid who applied to Harvard probably applied to one or more of the other Ivies.

I think it is interesting as to the “do the CCs curate the applications, and point a kid to just one Ivy” question. I would say they probably do-ish, only because there is a lot less drop off between Naviance and matriculation than I would expect if kids are blanketing Ivies with applications and getting into multiple Ivies.
