Which FE Exam Should You Take? A Guide to Choosing Your Discipline

Deciding which FE exam discipline to take is one of the most important steps in your journey to becoming a licensed professional engineer. The FE (Fundamentals of Engineering) exam is your gateway to EIT certification and, eventually, the PE license. But with several discipline-specific exams offered by NCEES, you might be wondering, “Which one is right for me?”

This guide covers how to choose the best FE exam discipline based on your educational background, career plans, and personal strengths—so you can feel confident on test day and set yourself up for long-term engineering success.

NCEES FE Exam Options

NCEES currently offers the following computer-based FE exams:

• Chemical
• Civil
• Electrical and Computer
• Environmental
• Industrial and Systems
• Mechanical
• Other Disciplines

Each exam is designed to test fundamental engineering knowledge for an entry-level engineer in that discipline. All FE exams are:

• Computer-based (CBT): Delivered year-round at approved Pearson VUE test centers
• 110 questions: All multiple-choice
• 6 hours total: Includes a 25-minute break
• Reference Handbook: Online, searchable during the exam
• On-screen calculator: Provided by NCEES (no personal calculators allowed)

How to Choose the Right FE Exam

1. Start With Your Degree/Background

The most common—and typically the best—option is to take the FE exam that matches your undergraduate engineering major. For example:

• Civil engineering majors should take the FE Civil exam
• Mechanical engineering majors should take the FE Mechanical exam
• Environmental, electrical, chemical, and industrial engineers should take the corresponding discipline

The questions on each discipline exam closely resemble the coursework you’ve completed. If you’ve just finished a degree in one of these areas, you’ll be best equipped for that specific FE exam.

What if My Major Isn’t Listed?

If you studied a less common or interdisciplinary field (like materials, agricultural, biomedical, or nuclear engineering), or your transcript doesn’t match a standard discipline, consider the FE Other Disciplines exam. This version covers a broad base of engineering fundamentals and is geared toward majors that don’t align perfectly with a single specialty.

2. Consider Your Future PE Plans

It’s also smart to plan ahead. The discipline you choose for the FE exam doesn’t absolutely lock you into that path for the PE exam later, but:

• Some state licensing boards prefer or require you to take both the FE and PE in the same discipline
• Your future employer or preferred industry may expect a certain discipline

Example: If you want to become a licensed civil engineer and sign off on infrastructure projects, it’s safest to take the FE Civil exam, then the PE Civil exam later.

If you’re unsure, check with your state’s licensing board or use Stamp Prep’s resources to investigate typical paths for your preferred career.

3. Assess Your Strengths and Weaknesses

While most students perform best in their own discipline, there are some cases where you might feel more prepared for a different exam:

• If you double-majored or took extensive coursework outside your main major
• If you’ve been working in a different sector since graduation
• If you’re switching careers to a new branch of engineering

Review the published exam specifications from NCEES for each discipline (available at ncees.org). Compare the content breakdowns with your academic history and choose the one you feel most comfortable with.

4. Use NCEES Resources

NCEES publishes detailed exam specifications and sample questions for every FE discipline. You can view these on the NCEES website. If you’re still undecided after reviewing course content, consider taking a free diagnostic assessment or practice exam through Stamp Prep. These tools can highlight which subjects are your strongest and weakest, making your decision easier.

5. Weigh Employability and Licensing Requirements

Sometimes employers or state requirements influence your decision. Research your state’s board rules and expectations in your intended field. For example, some states have unique exam requirements for environmental or structural engineering.

Switching Disciplines Is Possible

Many engineers worry that choosing the "wrong" FE discipline will lock them out of future opportunities. Good news: Passing any FE exam qualifies you for EIT (Engineer-in-Training) status in most states. While the ideal path is discipline-aligned, many engineers have successfully taken the FE Other Disciplines exam and pursued PE licensure in their area of expertise. Just be aware that you may need to demonstrate additional experience or coursework if your FE and PE disciplines differ.

If you have questions about your state’s rules or your situation, Stamp Prep offers advising resources to help you plan your exam path.

Final Thoughts and Next Steps

When in doubt, stick with the FE exam that best matches your degree and intended career. Use the official NCEES specifications and Stamp Prep’s online diagnostic tools to double-check your readiness. Confirm your state’s licensing requirements and employer expectations so your choice fits your long-term goals.

The most important thing: preparing thoroughly for your chosen exam. Once you’ve booked your exam day, create a detailed study plan and start working through practice problems in your discipline’s content areas.

Stamp Prep offers tailored resources for all seven FE exam choices, including question banks, study schedules, and exam strategies. Whichever discipline you choose, you’ve got the support and resources you need to pass—good luck!
