This paper presents comparison of results obtained in two distinct courses, one graduate and one undergraduate, where engineering economy was one of the main components of the course. The graduate course is the advanced version of the undergraduate course. In both it was used the same methodology of assigning projects that involved the preparation of a report and a subsequent presentation of the results in an internal seminar. For the undergraduate course two seminars were presented by each group, one involving engineering economy and other involving managerial aspects of the industry. For the graduate course only one project was proposed since the project involved a more in depth analysis of the topic developed. Both courses were taught two years in a row and the paper presents comments and observations regarding the different results obtained in graduate and undergraduate levels.
