Journey to PE
In the United States, certain practices of engineering are required to be performed by a licensed engineer. This includes signing and sealing engineering plans and drawings, and some engineers working in teaching or government must be licensed. To obtain licensure in engineering, you must pass two national standardized tests (the FE, fundamentals of engineering, and the PE, principles of engineering) and then apply to your state's board to obtain the license (also called the PE, professional engineer.) The National Council of Examiners for Engineering and Surveying (NCEES) writes the standardized tests, which are specifically designed for several disciplines of engineering. Spoiler alert: If you've seen the home page on my website, you'd already know I have successfully obtained a PE in control systems engineering.
