The format every Civil exam shares
- 80 questions over a nine-hour appointment, which includes a tutorial and an optional scheduled break.
- Computer-based and offered year-round at Pearson VUE.
- Closed book with electronic references: the NCEES PE Civil Reference Handbook plus the design standards listed for your exam, all on-screen.
- Standards are supplied as individual chapters, and only one chapter can be open and searched at a time — knowing which chapter to open is its own exam skill.
- Standard multiple choice plus alternative item types (drag-and-drop, point-and-click, multiple-correct, fill-in).
- Scored against a scaled cut score — NCEES publishes no fixed passing percentage. Answers that rely on a standard are scored against the edition NCEES lists, and no other.

Exam FAQ
How is the PE Civil exam structured?
Five separate exams — Construction, Geotechnical, Structural, Transportation, and Water Resources & Environmental — and you sit one. Each is 80 questions over a nine-hour appointment, closed book with the NCEES PE Civil Reference Handbook and that exam's design standards on-screen, computer-based and offered year-round.
Is there still a breadth section?
No. Since April 2024 each PE Civil exam is a single 80-question test on its own specification. Study material written for the old breadth-and-depth format is organized around an exam that no longer exists, so check its date before you rely on it.
Which PE Civil exam should I take?
The one closest to the work you do — you only need to pass one. The comparison above shows who each is for and its first-time pass rate.
What references do I get?
The NCEES PE Civil Reference Handbook plus the design standards NCEES lists for your exam, supplied electronically. Standards arrive one chapter at a time, and answers are scored against the listed editions only. For Water Resources & Environmental, that list changes with the April 2027 exam.
What score do I need to pass?
NCEES uses a scaled cut score and doesn't publish a fixed passing percentage. The goal is command of the tested areas, not a magic number.
What if it takes more than one attempt?
The exam is offered year-round, within NCEES and state-board attempt limits. A retake plan that changes the method — not just the hours — is what moves the score.
