The PE exam tests your ability to practice competently in a particular engineering discipline. It is designed for engineers who have gained at least four years’ post-college work experience in their chosen engineering discipline.
Each PE exam lasts 8 hours and is split into a morning and an afternoon session.

If you are taking either the PE Civil or PE Mechanical exam, you will be asked to select an afternoon module during registration. Your answer sheet will be scored based on the module you selected when registering.
The PE exam is an open-book exam. You are allowed to bring reference materials to the exam, provided they are bound and remain bound during the exam. Loose paper may be bound with ring binders, brads, plastic snap binders, spiral-bound notebooks, and screw posts—but not with staples. Sticky notes and flags are permitted only when they remain attached to book pages.
Scoring and reporting
Exam results are typically released to the licensing boards 8–10 weeks after the exam. Depending on your state, you will be notified of your exam result online through your My NCEES account or via postal mail from your state licensing board.
