NCEES Fundamentals of Engineering (FE) Environmental Exam
The first step to a PE license in environmental engineering — 110 computer-based questions on water, wastewater, air, waste, groundwater and risk, solved with the NCEES FE Reference Handbook.
About the exam
The FE Environmental exam is the NCEES Fundamentals of Engineering exam for environmental engineering. Passing it — usually during or right after an ABET-accredited degree — earns Engineer Intern (EI) or Engineer-in-Training (EIT) status in most states, the first step toward a Professional Engineer (PE) license.
It's a computer-based exam at Pearson VUE test centers: 110 questions in a 6-hour appointment that includes a short tutorial and an optional 25-minute scheduled break. It's closed book — the only reference is the searchable electronic NCEES FE Reference Handbook on screen — and you may bring only an NCEES-approved calculator. Questions are mostly multiple choice, with some alternative item types such as numeric fill-in.
Our practice follows the 15 NCEES knowledge areas with every numeric answer worked from the givens — BOD and Streeter-Phelps, reactor sizing, clarifier overflow rates, Henry's law, Gaussian plumes, cancer risk, Thiem drawdown, landfill volumes and the rest — with wrong answers built from the slips examinees actually make, plus flashcards, worked case walkthroughs, illustrated guides and full-length timed practice.

The exam blueprint
NCEES FE Environmental CBT exam specifications, effective with the July 2020 exams (15 knowledge areas, 110 questions) — still the current posted specification as of October 2026; NCEES's Fall 2026 and Summer 2027 change notices list no FE Environmental change. Uses the searchable NCEES FE Reference Handbook supplied on screen. — Math, statistics, ethics and regulations, economics, fundamental principles, environmental chemistry, risk assessment, fluids and hydraulics, thermodynamics, surface water, groundwater, water and wastewater, air quality, solid and hazardous waste, and energy.

Built on the NCEES specifications
Every question is tagged to one of the 15 FE Environmental knowledge areas, weighted like the real exam's question ranges.
Hints that point to the Handbook
Reveal the equation or Handbook section to search for when you're stuck. Every numeric answer is worked step by step, and every distractor is a mistake worth recognizing.
Adaptive practice
Questions steer toward your weakest knowledge areas and get harder as you get stronger.
Full-length timed practice
110 questions in 5 hours 20 minutes — the real FE pace — with a pacing indicator and full review.
Drawn problems
Clarifiers, reactors, plumes, wells, hydrographs and DO sag curves drawn the way FE problems present them.
Progress in every area
Each knowledge area moves from Not started to Exam ready, so you know exactly what to study next.
Test at home or at a center
Create a MyNCEES account, choose FE Environmental, pay the fee and schedule at a Pearson VUE test center. Check your state board's rules too — some boards require a separate application for EI/EIT certification after you pass.
At a Pearson VUE test center
- Computer-based, offered year-round at Pearson VUE centers.
- Bring valid, unexpired government-issued ID that matches your MyNCEES name.
- Only NCEES-approved calculator models are allowed; a reusable notepad and marker are provided.
- The FE Reference Handbook is on screen — practice searching the same PDF beforehand.
Before test day
- Download the free FE Reference Handbook from MyNCEES and work practice problems with it, not a textbook.
- Practice with your exact calculator model — speed matters at about three minutes a question.
- Know the retake rules: one attempt per testing window and no more than three in any 12-month period.
- Confirm what your state board needs for EI/EIT status after you pass.
Exam-day game plan
How to walk in ready — and how to pace 110 questions in 5 hours 20 minutes.
Pacing checkpoints
Our timed test runs 110 questions in 320 minutes — the real FE exam time. The real appointment adds a short tutorial and an optional scheduled break, and the Reference Handbook is on screen beside each question.
The week before
- Take one full timed practice exam using the Handbook PDF, then review every miss.
- Practice Ctrl+F search terms for the formulas you use most — BOD, Monod, Henry's law, Gaussian plume, Thiem.
- Re-derive units for the conversions you keep slipping on (mg/L to lb/day, ppm to µg/m³, MGD to m³/s).
- Confirm your Pearson VUE appointment, ID and calculator model.
During the test
- Answer the quick conceptual and regulatory questions first and flag long calculations.
- Search the Handbook by keyword, then check the variable definitions and units beside the equation.
- Write units on every number on your notepad — most wrong choices are unit slips.
- Take the scheduled break; the second half is just as long.
- Never leave a question blank — there's no penalty for guessing.
Keep your head
- You don't need a perfect score — the cut score is set psychometrically, not at a fixed percentage.
- If a problem stalls past five minutes, flag it and move on.
- Change an answer only when you find a specific error in your first solution.
After you pass
- Results are pass/fail and usually post to MyNCEES within about 7–10 days.
- Apply to your state board for Engineer Intern (EI) or Engineer-in-Training (EIT) certification if your board requires it.
- Next comes qualifying experience (typically four years) and the PE Environmental exam.
- FE results don't expire with NCEES; check your state board's rules.
