The Fundamentals of Engineering exam (FE) is required for engineers who plan on seeking professional licensure. Once a candidate has passed the FE exam, an Engineer in Training (EIT) certificate is issued. After an EIT works for a specified number of years (varies in each state) under the supervision of a professional engineer, the candidate is eligible to sit for the Principles and Practice in Engineering exam (PE) and become licensed as a professional engineer.
