That sounds pretty impressive -- Wharton School of Business.  But I would be a lot more impressed if it said "MBA Wharton School of Business."  The problem with people who credential themselves on resumes with "Harvard Business School" or "Wharton School of Business" is that all too often they have attended a program at one of those schools that lasted a few weeks and there is no degree attached.  Its not like they completed a two-year MBA program.  So when I see an impressive school listed under "Education" but no degree also listed -- I get a little suspicious.
