A methodology for assessing ethics educationneeds in a Masters of Business Administration(MBA) program is proposed and applied at oneinstitution by comparing the ethical judgmentof MBA and MPA (Masters of PublicAdministration) students over a variety ofbusiness scenarios. Implications are discussedfor ethics education and its assessment in thisand other MBA programs. MPAs were chosen asthe comparison group because their education,organizational knowledge, and work experienceare expected to promote reasonable judgments. They were also selected because future negativeconsequences are likely from an ethics gapbetween MBA and MPA graduates. MBAs were lesscritical in the current study, and were alsomore likely to report reliance on egoism, aprinciple strongly associated with greatertolerance of the practices described. Anadditional factor, however, appeared tocontribute to the MBAs' less critical judgment. Ethical decision-making models suggest thisfactor was ethical perception. Suggestions aremade for modifying ethical principles andperceptions where indicated. Decision makersare urged to assess ethics education needs intheir own MBA programs, particularly if theyhave not added significant ethical content totheir curricula.
