While not required in all industries, there are a variety of career paths that require, or strongly encourage, a licensed Professional Engineer. In addition to relevant work experience, the Fundamentals of Engineering Exam (FE Exam) and the Professional Engineering Exam (PE Exam) must both be passed in order to be licensed. As the FE Exam covers fundamentals, it is highly suggested that it be taken at the completion of one’s undergraduate studies. These are links to the most recent FE exam information and the FE exam for ISE.
Approximately 10% of the members of the Institute of Industrial Engineering are Professional Engineers. While being a PE is critically important in some other engineering areas, it is not in ISE unless you wish to go into consulting as a principal of a consulting firm. In this case it is very valuable to be a PE. You should decide whether or not you wish to become a PE in order to choose your technical electives. It is easier to prepare for the FE examination while still in school than after graduating.
To further help prepare for the exam, Tau Beta Pi runs an after-hours, non-credit preparation course for the FE exam each semester.
