<p>MomOfFour -- I actually didn't read the zip code section in the same way you did. As I interpreted it, she was able to pinpoint a particular school BASED on its zip code and the rest of the staff happened to be unfamiliar with said school. Don't know which way it went, but that's my own, hopefully less worrisome interpretation.</p>
<p>That said, adcoms often have access to plenty of other info about a high school...what your child has taken relative to what the school offers, sometimes median GPA, your child's rank, occasionally the school's local/national ranking, and so forth. Admissions officers shouldn't be too confused, and even if they are, as a previous poster mentioned, it doesn't have to work out against you. I wouldn't let it be a major concern.</p>
