My sister loves accounting and has an AS and BS in accounting and plans to sit for her CPA. She has successful businesses and plans to sell them both and start to take it easy. She is thinking of semi-retiring and just teaching online. She has done accounting work for over 20 years for her business and she does side work for a law office, art gallery, dr office, etc. Would an MBA with a concentration in Accounting + CPA be good enough to teach or would she need an MAcc + CPA? Thoughts....?
