I recommend that your nephew apply early to a safety school that works financially and that he likes. “Early” here means calendar-wise, and not early decision. An early acceptance will reduce the stress somewhat. A college with an admissions rate of 25% or lower should not be considered a safety school for a student with Ivy-level academics, unless there are other special qualities.
Then apply early on to another school where the applicant pool may be a bit stronger. For example, the University of Michigan for an out-of-state student fits into this category. An Ivy-qualified student who applies early in the fall from out of state will almost certainly be admitted. The same student applying in late February or March might not be admitted. UNC Chapel Hill probably fits this description as well.
Early decision is a good idea only if your nephew is certain about the college he would like to attend–and I should probably add, if he has a reasonable chance of acceptance.
You probably know that the SATs were re-centered sometime in the 1990’s, pushing the scores up. This means that the ballpark SAT scores you might know from your high school years are no longer good guides. As a very rough guide: Add 100 or 150 to the old scores and compare again. You can find actual concordance tables on line for a more exact correspondence.
I suggest that your nephew and his parents read the college web sites closely. Most of them will strike you as “blah, blah, blah.” However, occasionally there are hints about the outlook of particular admissions offices.
For an Ivy-level student who is genuinely outstanding academically and has strong EC’s, I still would not recommend applying to Stanford under their SCEA or REA program (unless your nephew is from California and/or is a recruited athlete). In my experience, students in this group are better off applying to one of the Ivies SCEA or REA. Stanford flat out turns down quite a few of the early applicants, who would almost certainly have been deferred and possibly accepted at the Ivies. Also, the Ivy-level student who is genuinely outstanding academically and has strong EC’s, but nothing in the “knock your socks off” category and no really unusual circumstances is quite likely to be deferred by Stanford, but may be accepted by an Ivy–based on my collected observations. This could vary geographically, though. And of course, I haven’t seen the essays nor the letters of recommendation for any of the students in my informal “database” of observations (as other posters are bound to object)–on the other hand, I do know the students themselves moderately well.
The existence of SCEA/REA is a mixed blessing, in my view. For the students who are accepted early, it’s wonderful. For students who are deferred or rejected, it probably adds to the stress. There are two practices that I think are good if a student is applying to a “top” school SCEA/REA: First, applications to other highly competitive schools should ideally be submitted before the SCEA/REA decision comes out. (These days, the deadlines may ensure that, but maybe not.) Second, it may be a good idea to adjust the mix of colleges in the application set, based on the “feedback” from the SCEA/REA decision. The other highly competitive schools may see the applicant quite differently from the first, but filling out the application set from the middle at that point is probably a good strategy–i.e, insert some schools between the true safeties and the top of the list.
Hope this is helpful.
