A PE License, or Professional Engineer License, is a certification that allows engineers to practice their profession legally and offer services to the public. To obtain this license, candidates typically need to complete a four-year engineering degree, pass the Fundamentals of Engineering (FE) exam, gain relevant work experience under a licensed engineer, and pass the Principles and Practice of Engineering (PE) exam. Having a PE License demonstrates a high level of competence and commitment to ethical standards in engineering. It is often required for engineers who wish to take on certain responsibilities, such as signing off on projects or providing engineering services directly to clients.
