When my middle d was looking at schools a few years ago, Vandy had a full listing of all their merit scholarships in their catalog. It was an extensive list. I don't know if there's a PDF version online for the current year - maybe your high school or library has a hard copy of the catalog, if not.
You've probably already seen this webpage:
Merit Scholarship Programs
It refers to Vandy's "limited" merit scholarships in addition to the named opportunities, ranging up to full tuition. I don't know if this means that Vandy has changed its program for incoming students, but I can tell you that, as a College Scholar in A & S, my d has a 3/4 tuition Dean's Scholarship and a $2K annual National Merit scholarship. If you're a NM Finalist, Vandy awards you a $5K annual scholarship unless you also receive another Vandy merit scholarship, in which case the NM award is $2K annually. Generous, generous school.
