I know this posting is somewhat dated, but I wanted to elaborate on Patricia's answer for future readers.
For almost forty years, Wharton has enabled individuals to retain their full-time job while earning the Wharton MBA degree through its MBA Program for Executives. With the opening of the Wharton|San Francisco campus in 2001, the same valuable MBA Program for Executives has become even more accessible.
The Wharton MBA Program for Executives replicates Wharton’s highly acclaimed traditional full-time MBA program. It offers the same courses, number of class hours, faculty and reading lists. Students attend classes every other Friday and Saturday with a few three-day and two week-long sessions during the 24 month program. The result is a true Wharton MBA degree.
