FE Mechanical Pass Rate, Format & Study Guide

The Fundamentals of Engineering (FE) exam is administered by NCEES (National Council of Examiners for Engineering and Surveying), and FE Mechanical is the mechanical-engineering-specific version — the entry-level exam in the two-step pathway (FE, then later PE) toward full Professional Engineer licensure. Like every FE discipline exam, FE Mechanical exists specifically to validate foundational engineering knowledge at or near the point of finishing an undergraduate mechanical engineering degree, distinct from the PE exam later in the pathway, which validates a licensed engineer's readiness to take independent professional responsibility for engineering work.

FE Mechanical is, for most mechanical engineering graduates pursuing eventual PE licensure, the practical first professional milestone after graduation — many mechanical engineering employers expect or actively encourage new graduates to pass the FE soon after finishing school, both because the material is freshest immediately post-graduation and because it signals genuine intent to pursue full licensure down the line. Because NCEES retains a passing FE score indefinitely, passing early removes any pressure to retake it later, letting engineers focus entirely on accumulating the qualifying work experience needed for the PE exam without any expiration clock running on their FE result in the background.

FE Mechanical is for mechanical engineering students nearing graduation and recent graduates from EAC/ABET-accredited programs who are on (or considering) the path toward eventual PE licensure — the same entry-point role FE Civil plays for civil engineers, just for the mechanical-engineering discipline specifically. It is not designed for already-licensed engineers or candidates without a mechanical-engineering-degree background.

The certifying body does not publicly publish an official pass rate for this exam. Be wary of third-party sites citing a specific number here — treat any pass-rate claim you see elsewhere for this exam as unverified.

NCEES limits every FE exam (all disciplines, Mechanical included) to one attempt per testing window, with a maximum of 3 attempts in any rolling 12-month period. Testing windows run quarterly (January-March, April-June, July-September, October-December), so at minimum you're waiting for the next window to open before retesting — there's no same-window retake regardless of how early you fail.

NCEES grades on raw correct answers only (no penalty for wrong answers), then converts that to a scaled score to normalize for minor difficulty differences between exam forms — confirmed directly on NCEES's own exam-scoring page. Critically, NCEES does not publish the passing score or the number of correct answers needed; it states explicitly there's no predetermined percentage of examinees who should pass or fail. Results are reported as Pass or Did Not Pass only — no numeric score is given to examinees who pass, though those who don't pass get a diagnostic breakdown by subject area.

The exam is computer-based, delivered at Pearson VUE test centers, consisting of 110 questions covering the full breadth of mechanical engineering — statics, dynamics, mechanics of materials, thermodynamics, fluid mechanics, heat transfer, mechanical design, materials, and controls, among other core mechanical-engineering topics. The full appointment runs 6 hours: an 8-minute tutorial, 5 hours and 20 minutes of actual exam time, and a scheduled 25-minute break.

NCEES publishes FE Mechanical's knowledge-area weighting as question-count ranges per topic area (for example, a range like "10-15 questions" for a given area) rather than fixed percentages the way some other credentials' blueprints present — meaning the exact number of questions from any given content area can vary somewhat between exam forms within the published range. Candidates preparing seriously should reference NCEES's current FE Mechanical exam specifications document directly, which lists these ranges across the exam's full breadth of mechanical topics, rather than converting the ranges into an assumed fixed percentage that NCEES itself doesn't publish that way.

Like FE Civil, FE Mechanical requires no professional work experience — NCEES designed the FE exam broadly for recent graduates and students close to finishing an undergraduate engineering degree from an EAC/ABET-accredited program, making it the entry-level step toward eventual PE licensure rather than a standalone practice credential. Most candidates sit for it around graduation, well before the multi-year experience clock toward PE licensure begins.

The exam fee is $225, payable directly to NCEES, separate from (and substantially lower than) the $400 PE exam fee paid later in the licensure pathway. Examinees get one attempt per testing window and are capped at no more than three attempts in any 12-month period, with the full $225 fee due again for any retake.

As with FE Civil, this is one of the few credentials on this site with no ongoing maintenance requirement in the usual sense — NCEES retains a passing FE score indefinitely, so there's no expiration or periodic re-testing requirement at the NCEES level once passed. The Engineer in Training (EIT) or Engineer Intern (EI) designation some states award based on a passed FE score is a separate, state-specific matter that in most states also doesn't expire, though a handful of states apply their own renewal formalities to the certificate itself — confirm your specific state board's rules if you hold (or are pursuing) that designation, rather than assuming the FE score's indefinite validity at the NCEES level automatically covers every state's own EIT/EI certificate rules too.

110 questions in 5 hours 20 minutes of actual exam time works out to roughly 3 minutes per question, though NCEES expects some questions to take seconds and others several minutes, so practicing under real time pressure matters as much as content mastery. NCEES's own FE Mechanical specification lists 14 knowledge areas as question-count RANGES rather than fixed percentages, so build your study plan from the official NCEES exam specification rather than a guessed weighting, and since you get only 3 attempts per year, treat your first sitting as the one to be genuinely ready for rather than a low-stakes trial run.

No changes to the FE Mechanical exam's core 110-question/6-hour format or NCEES's $225 fee have been publicly announced as of August 2026. As with FE Civil, NCEES periodically revises its exam specifications to reflect the current mechanical-engineering body of knowledge — candidates should pull the current FE Mechanical exam specifications directly from ncees.org before finalizing a study plan, rather than relying on an older specifications document.
