Frequently asked questions
What is a Professional Engineer (P.E.)?+
A Professional Engineer is an engineer licensed by a US state board after passing the FE and PE exams and completing the required experience (typically four years under a licensed P.E.). Only a P.E. can legally sign and seal engineering documents within their licensing state.
How do I become a P.E. in the United States?+
Earn an ABET-accredited engineering degree, pass the Fundamentals of Engineering (FE) exam, complete four years of qualifying engineering experience under a P.E., then pass the discipline-specific Principles & Practice of Engineering (PE) exam administered by NCEES.
What's the difference between an engineer and a Professional Engineer?+
Any engineering graduate can hold the title of engineer, but only a Professional Engineer (P.E.) can offer services to the public, take legal responsibility for designs, and seal drawings submitted to government authorities.
Do all engineers need to be Professional Engineers?+
No. Engineers working under the industrial exemption (in-house at a manufacturer, for example) often do not require a P.E. license. But any work submitted to a public authority — buildings, infrastructure, utilities — typically must be sealed by a P.E.
Can I verify a Professional Engineer's license?+
Yes. Every US state board publishes P.E. license status as public record. VectorCore aggregates these records live so you can confirm an engineer's status, license number, and discipline without leaving the page.
