How hard is the PE Civil exam? Structural vs Transportation vs Water Resources

Pass rates for every PE Civil depth

These are NCEES's own figures, from the "Overall takers" columns of NCEES Squared 2025, which covers NCEES's fiscal year FY2024-25 (2024-10-01 to 2025-09-30). NCEES publishes Squared once a year. Sorted by first-time rate.

Read the volumes as well as the rates. Water Resources and Environmental has the most first-time examinees and the best rate; Geotechnical, with 782, sits second on rate and last on volume. A rate measured on fewer than a thousand people can move several points from one year to the next, so treat a two- or three-point gap between depths as noise. The twelve-point spread between Water Resources and Environmental and Transportation is real; the gaps inside it are not a reason to choose a depth.

What makes each depth hard

The three depths we cover, read from the NCEES specifications rather than from reputation. Each still carries some general civil areas, and which ones differ: Water Resources has project planning, soil mechanics, materials and sitework; Transportation has project management and a geotechnical and pavement area; Structural has soils and materials but no planning or sitework area. That is where candidates who prepared only their specialty lose questions.

How to pick your depth

1. 1.Take the depth your experience record describes. The questions your practice made routine are the cheapest points on the exam, and every depth still tests general civil areas alongside the specialty.
2. 2.Do not switch depths for a pass-rate gap under about five points. That is within the noise of a table measured on a few hundred to a few thousand people a year.
3. 3.If you want a structural credential, check whether you mean the SE exam. PE Civil: Structural is one of the five PE Civil exams, not the SE, and the two are prepared differently.
4. 4.Plan to take it once. At $400 per attempt and at least half of repeat takers failing again in every depth, the cheapest exam is the one you pass the first time. That means preparing the general civil areas, not only the depth.

Common questions

Which PE Civil depth has the highest pass rate?

Water Resources and Environmental, at 71% for first-time takers in NCEES Squared 2025 (FY2024-25), with 4,313 first-time examinees in the period. The five depths sit within a twelve-point band, from 59% to 71%, so the depth you choose matters less than taking it prepared: repeat takers pass at 40–50% across the family.

Is the PE Civil exam harder than the FE?

Different rather than simply harder. The PE Civil exam is 80 questions in 8h of exam time, about 6 minutes per question by our arithmetic and roughly double the FE's time per question, because the questions are longer and closer to design work. First-time pass rates for the PE Civil depths run 59–71%, which is in the same band as the FE disciplines; the gap opens for repeat takers, who pass far less often on both exams.

How do I choose my PE Civil depth?

Take the depth that matches the work you do, because that is the work your experience record describes and the reference material you already read. Every depth's specification still mixes in general civil topics (soils in all of them; planning, cost estimating or sitework in some), so a switch to a depth with a marginally higher pass rate buys little and costs you the questions your practice would have made easy. The one exception worth knowing is Structural: candidates who want a structural-only credential usually mean the SE exam, which is separate.

How long is the PE Civil exam, and what does it cost?

80 questions in 8h of exam time inside a 9h appointment that also holds the nondisclosure agreement, the tutorial and a scheduled break; the break does not come out of your exam time. It is a closed-book, computer-based test offered year-round at Pearson VUE centers. The NCEES fee is $400 per attempt, paid when you register through MyNCEES; some state boards also charge their own application fee. NCEES allows one attempt per testing window and no more than three attempts in a 12-month period.

What reference material do you get on the PE Civil exam?

The NCEES PE Civil Reference Handbook on screen, plus the design standards the specification lists for your depth. For Water Resources and Environmental that is the Ten States Standards (Wastewater Facilities 2014, Water Works 2018), for exams through March 2027; for Transportation it is the AASHTO standards (Green Book 7th ed., HSM, Roadside Design Guide, pedestrian and pavement guides), HCM 6th ed. (TRB), MUTCD 2009 (FHWA), FHWA HDS-5, for exams through March 2027. NCEES has posted updated design standards for exams from April 2027. No notes, books or references of your own come into the room (you may bring one NCEES-approved calculator), so practicing against the searchable reference rather than a printed copy is part of the preparation.
