What is a stationary engineer license?

Some states require stationary engineers to be licensed. The requirements to get a license vary from state to state. Some possible requirements include a minimum time as a resident of the state in which you work, a certain number of hours of work experience, completion of an apprenticeship program, and passing a written exam. Some states allow a probationary license so workers without experience can begin working and receive training on the job. When considering this career, it is best to investigate your state’s licensing requirements.
