I know there have been others looking for an online MBA program with an Accounting concentration in the past. I happened across a program today and thought I would share. Tennesee Tech offers their MBA program entirely online and beginning this Summer the entire Accounting concentration will also be online. The business school is AACSB-accredited and the Accounting department has separate AACSB-accreditation. The tuition is a little pricey for out of state students, though. http://www.tntech.edu/accountingonline/index.htm
I also thought I would mention that they offer some pre-MBA modules for non-business undergraduates. The courses are on CD-ROM and are only $325 each. They are NON-CREDIT courses; however, they may be a good option for those who are looking to learn enough to waive out of another school's Foundation or Pre-MBA courses. The representative I spoke with indicated that any student may take those modules without applying for a degree at Tennessee Tech. The link below shows a listing of each of the modules offered. http://www.tntech.edu/mba/fees.htm
