The graduate degree in business administration (MBA) from a quality, well respected school holds a high level of marketability because it teaches students how business works and the language of the business world. It prepares students for careers beyond a traditional economics or accounting degree and readies them for executive leadership roles. The MBA works well with any undergraduate degree (not just business) adding business savvy to an employee's portfolio. In the field of health care, doctors and nurses are using the MBA to complement their degrees and get ready for roles as administrators and hospital executives.
