How hard is the FE exam, really?

FE exam pass rates by discipline

These are NCEES's published figures for all first-time examinees in its most recent reporting year. Note the third column: the repeat-taker pass rate is roughly half the first-time rate in every single discipline. That gap is the most important number on this page, and we come back to it below.

Source: NCEES, Squared 2025 (all first-time examinees, NCEES fiscal year October 1, 2024 – September 30, 2025). Examinees holding a bachelor’s degree from an ABET/EAC-accredited program do somewhat better than the figures above — 64–72% first-time, depending on discipline. Beware of prep sites quoting those higher numbers as though they applied to everyone.

The spread between disciplines is real but modest: no FE exam is a giveaway and none is unpassable. What the table actually argues is that the difference between passing and failing lies in preparation rather than in which exam you sit — because the same people, facing the same exam a second time, do dramatically worse when they have not changed how they prepare.

What you are actually up against

The FE is a computer-based, closed-book exam: 110 questions in 5 hours 20 minutes of exam time, inside a 6-hour appointment that also covers a 2-minute nondisclosure agreement, an 8-minute tutorial, and a 25-minute scheduled break. Your only reference is the searchable on-screen NCEES FE Reference Handbook. The exam fee is $225, paid to NCEES.

Do the division and the real challenge appears: about 2 minutes 55 seconds per question, spread across 14 to 17 knowledge areas depending on your discipline — essentially everything you touched in your first two years of engineering school. Not every question is standard multiple choice, either. NCEES also uses what it calls alternative item types: multiple-correct questions, point-and-click on a graphic, drag-and-drop, and fill-in-the-blank. There is no partial credit on any of them.

Why prepared people still fail — our read

NCEES does not publish reasons for failure, so what follows is our judgment from building this question bank and talking to candidates — not statistics. Take it as a working theory you can test against your own weak spots.

1. 1

   Breadth, not depth

   Each FE exam spans 14-17 knowledge areas, from mathematics through ethics and engineering economics to your discipline core. Almost nobody is fresh on all of them, and the exam punishes the three areas you skipped far more than it rewards the one you mastered.

2. 2

   Time pressure

   Under three minutes per question means there is no time to derive anything from first principles. If you cannot recognize the problem type and find the governing equation quickly, a question you genuinely know how to solve still costs you two others.

3. 3

   Handbook unfamiliarity

   The FE Reference Handbook is your only reference, and it is hundreds of pages. Candidates who meet it for the first time on exam day burn their minutes searching it. Candidates who practiced with it open navigate by muscle memory.

4. 4

   Practicing on problems that are too easy

   The most common trap. Textbook problems are cleaner, friendlier, and slower than exam problems. If your practice does not match the exam's style, figures, and pacing, then your first genuinely exam-like problem happens on exam day - which is the worst possible time to meet it.

A study plan that matches the exam

NCEES publishes no official study-time guidance, and neither will we pretend to a precise number. Our recommendation is roughly 2–3 months of consistent work, longer if you have been out of school a while. What fills those hours matters more than the hour count:

• Take a timed diagnostic first. Find your three weakest knowledge areas before you spend a month polishing your strongest.
• Study with the FE Reference Handbook open from day one. Every practice problem should end with you knowing where its equation lives.
• Drill exam-style problems, not textbook problems - matching difficulty, figures, and question formats, under time.
• Answer every question. There are no deductions for wrong answers, so a blank is strictly worse than a guess.
• Finish with at least one full-length, 110-question timed mock exam. Pacing is a skill, and exam day should not be your first repetition of it.

Common questions

What percentage of people pass the FE exam?

In NCEES's most recent published data (fiscal year 2024-25), 61-69% of first-time takers passed, depending on discipline. FE Mechanical was highest at 69%; FE Civil and FE Other Disciplines were lowest at 61%. Repeat takers passed at 25-37% - roughly half the first-time rate - which is why your first attempt is worth preparing for properly.

What score do you need to pass the FE exam?

NCEES does not publish a passing score, and there is no fixed percentage to hit. Your raw answers are converted to a scaled score representing your ability level, which is compared against a minimum standard set by subject-matter experts using psychometric methods. Two things follow: you do not need anything close to 100%, and there are no deductions for wrong answers - so never leave a question blank.

How long should I study for the FE exam?

NCEES does not publish study-time data, so treat any specific number you see online with suspicion. Our guidance: budget roughly 2-3 months of consistent study, and lean to the longer end if you graduated several years ago - the usual problem is rust on fundamentals you have not touched since sophomore year, not ability. What matters more than total hours is what fills them: timed, exam-style problems worked with the reference handbook open.

Is the FE exam harder than the PE exam?

They are hard in different ways, and the pass rates are closer than most people expect - NCEES's 2024-25 data shows first-time PE pass rates in the 59-65% range for the civil depths, comparable to the FE. The FE is a breadth exam: 110 questions across 14-17 knowledge areas at under three minutes each. The PE is a depth exam in a single discipline, with longer, more involved problems. Breadth is usually the harder thing to study for; depth is usually the harder thing to solve.

What happens if I fail the FE exam?

You can retake it. NCEES allows one attempt per testing window - the FE has four windows a year (January-March, April-June, July-September, October-December) - and no more than three attempts in any 12-month period. You pay the exam fee again. Before you reschedule, change what you are practicing: the repeat pass rate is about half the first-time rate, which tells you that re-reading the same notes does not work. Drill exam-style problems under time until the handbook feels like home.
