Benefits of and Requirements for Engineering Licensure
Graduates of engineering programs may not legally call themselves "engineers" nor offer engineering services to the public until they have complied with rigorous experience and examination requirements. Although the details of these requirements differ from state to state, they generally include graduating from an ABET-accredited program, accumulating several years of progressive professional experience, and passing two licensing examinations.
The first of these examinations, called the Fundamentals of Engineering (FE) exam, is usually taken during a student's junior or senior year of college. The second, called the Principles and Practice of Engineering (PE) exam, may be taken only after a graduate has obtained the required professional experience.
A full explanation of the benefits of and requirements for licensure is available from the National Council of Examiners for Engineering and Surveying (NCEES).
