So, you’ve decided to embark on an engineering career. You’ve survived undergraduate courses like Thermodynamics, you’ve aced Differential Equations, and now you can probably build a passable bridge out of spaghetti. Now, you’re staring down another challenge on your quest to become a licensed professional engineer: the Fundamentals of Engineering exam, or FE exam for short.
The FE, administered by the National Council of Examiners for Engineering and Surveying (NCEES), is the gateway to your EIT certification and your first major step after graduation. But you’ve got one looming question: just how long is the FE exam? Let’s break it down.
Key Takeaways
- Total Time: The FE exam is a 6-hour appointment, but the actual exam time you spend answering questions is 5 hours and 20 minutes.
- Exam Structure: It’s a computer-based test split into two sessions, with a 25-minute scheduled break in between to stretch your legs and question your life choices.
- It’s a Marathon: Endurance is key. You’ll need to manage your time and energy effectively across 110 exam questions without your brain turning to mush.
- The Handbook is Your Friend: This is an FE exam open-book test, but you can only use the official, searchable, electronic FE Reference Handbook provided during the exam.
- First Step to Licensure: Passing is the crucial first step to getting your Engineer in Training (EIT) certification and eventually earning that coveted PE license.
Breaking Down the FE Exam Clock
Okay, let’s answer your question. The total appointment at one of the NCEES-approved test centers is 6 hours long. But don’t panic, you won’t be furiously clicking away for all 360 minutes.
Here’s how that time is sliced up:
- Nondisclosure agreement (2 minutes): You promise not to reveal the secret handshake or any of the test questions.
- Tutorial (8 minutes): A quick guide on how the interface works.
- First section of the exam (approx. 2 hours and 40 minutes): The first half of the questions.
- Scheduled break (25 minutes): This is your official break time. Use it!
- Second section of the exam (approx. 2 hours and 40 minutes): The second half of the questions.
- Brief survey (a few minutes): You tell them what you thought of the experience.
When you do the math, the time you have for testing academic knowledge adds up to 5 hours and 20 minutes. The clock for each section runs independently and doesn’t stop, even if you finish early. And any time you have left in the first section doesn’t carry over to the second section, so manage your pace wisely.
What is the FE Exam, Anyway?
The Fundamentals of Engineering (FE) exam is a comprehensive test that verifies you have the minimum knowledge of core engineering concepts. Administered by the National Council of Examiners for Engineering and Surveying (NCEES), this engineering exam is your ticket to becoming an Engineer Intern (EI) or Engineer in Training (EIT), depending on your state board’s terminology. Passing it proves you have the foundational skills needed to work in the field while you gain the experience required to later sit for the PE exam.

The Nitty-Gritty: Exam Format and Content
The NCEES FE exam consists of 110 questions. The question formats can vary, including standard multiple-choice, point-and-click items where you identify a location on a graphic, and fill-in-the-blank questions. You won’t know which items are scored, so you have to complete and answer every single one. Don’t leave any unanswered questions, because a guess is always better than a blank.
Discipline-Specific Knowledge
A common misconception is that the FE is a single, generic exam. In reality, it’s a discipline-specific test. You’ll choose from one of several disciplines when you register. The most common ones include:
- Civil
- Mechanical
- Electrical and Computer
- Industrial and Systems
- Environmental
- Chemical
- Other Disciplines
The exam specifications for each discipline are different, focusing on the core subjects relevant to that field. Be sure to download the specs for your specific exam from the NCEES website to see the breakdown of topics and how many questions are dedicated to each area.
The All-Important FE Reference Handbook
Here’s some good news: the engineering FE exam is technically open-book. The catch? You can’t bring your own library of reference materials. Instead, you’ll get a digital, searchable PDF of the FE Reference Handbook. And I cannot stress this enough—make sure you get intimately familiar with this handbook! That is non-negotiable. Knowing how to quickly find formulas and tables in the current version is just as important as knowing the fundamentals.
Your Roadmap to Taking the FE Exam
Ready to sign up? The registration process is handled entirely through the NCEES website. Most students are eligible to take the FE exam during their senior year of an ABET-accredited engineering program or after graduation.
The exam is offered year-round at Pearson VUE testing centers. However, scheduling is organized into four testing windows: January–March, April–June, July–September, and October–December. You can take the exam once per testing window and a maximum of three times in 12 months.
Strategies for Conquering the FE Exam
From my perspective, time management is the biggest challenge. With 110 questions in 320 minutes, you have just under three minutes per question. If a problem is stumping you, flag it and move on. You can come back later if you have time, but don’t sacrifice five easy points for one hard one.
Make sure you have an NCEES-approved calculator and that you know how to use it blindfolded. And when that 25-minute break arrives, use every second. Get up, walk around, and eat a snack to refuel your brain for the final push.
After the FE Exam: What’s Next?
You’ll get your exam results via email, typically within 7-10 days. The result is a simple pass or fail. If you didn’t pass, don’t despair. NCEES gives you a diagnostic report showing your performance in each subject area, which means you can focus your studies for the next attempt. If you passed—congratulations! Your next step is to apply to your state’s licensing board for your EIT certification. After getting at least four years of acceptable work experience, you’ll be eligible to take the final hurdle: the Principles and Practice of Engineering (PE exam).
Final Thoughts
So, how long is the FE exam? It’s a six-hour commitment that tests not just your engineering knowledge but your endurance and time management. It’s a challenging but conquerable milestone. With a solid study plan, a deep familiarity with the FE Reference Handbook, and a calm approach on test day, you’ll be well on your way to earning those coveted letters after your name.
FAQs
This is a study strategy suggesting you should focus 80% of your effort on the top 20% of topics that make up the bulk of the exam questions. Use the NCEES exam specifications to identify these high-impact areas for your discipline.
NCEES doesn’t publish a specific number of correct answers needed to pass. The exam is graded on a pass/fail basis, and the passing score is scaled based on the difficulty of the questions you received.
For many recent graduates or students in their final semester, two months of dedicated study is often enough. However, if you’ve been out of school for a while, you might want to plan for three to four months to get back up to speed.
You cannot eat or drink in the testing room. However, you are allowed to access your personal locker during your 25-minute scheduled break, where you can store snacks and a drink to refuel.
This is subjective and depends on your strengths. Historically, pass rates for disciplines like Chemical and Environmental have sometimes been lower than those for Civil or Mechanical, but this fluctuates. The hardest FE exam is the one you aren’t prepared for.
