The FE Reference Handbook: A how-to guide for all engineers

The FE Reference Handbook, the only reference you’re allowed to use during any FE exam, is a searchable, ~500-page PDF provided by NCEES that contains nearly every formula, constant, and table you’ll need. You don’t have to memorize it all; learning to navigate it quickly is the skill that can actually improve your score. This guide shows you how.

Preparing for any Fundamentals of Engineering (FE) exam is a major commitment, given the sheer volume of formulas, constants, and technical concepts you’ll encounter. The FE Reference Handbook is a comprehensive resource provided during your test by the exam’s creators, the National Council of Examiners for Engineering and Surveying (NCEES). Whether your test date is around the corner or you’re just getting oriented, it’s your go-to companion for both preparation and test day.

What is the FE exam?

FE exams are comprehensive, computer-based assessments consisting of 110 questions, administered during a 6-hour appointment. That appointment includes a short tutorial and a scheduled break, leaving about 5 hours and 20 minutes of actual testing time. The exam is designed to evaluate mastery of fundamental engineering concepts among recent graduates and early-career professionals. Administered by NCEES, the FE is available year-round, so candidates can schedule at a time that works for them. Exams contain both general engineering topics and discipline-specific items, depending on the test you take. For example, the FE Civil will include questions on water resources and transportation, while the FE Mechanical will focus more on mechanical design.

Passing the FE exam is the first major milestone on the path to your Professional Engineer (PE) license. A passing score earns you the Engineer-in-Training (EIT) certification, a credential valued by employers for entry-level engineering positions. Before test day, make sure you’re familiar with the approved test-day policies to ensure a smooth experience.

What is the FE Reference Handbook?

The FE Reference Handbook is standardized across all FE disciplines and covers environmental, electrical, mechanical, and other engineering topics. As your primary preparation tool, this roughly 500-page handbook contains most of the formulas, tables, units, and definitions needed to solve exam questions efficiently. However, simply knowing it’s there does not guarantee success; learning to use it effectively is a must.

It’s a digital PDF developed and maintained by NCEES, the organization behind both the FE and Principles and Practice of Engineering (PE) exams. It brings together the engineering formulas, data, and reference materials that NCEES considers “fair game” for exam questions across all disciplines.

It isn’t meant to be read cover to cover; instead, it serves as a practical knowledge repository you can consult during the test. Understanding its structure and navigating it quickly can save time, reduce stress, and improve exam-day performance. Treat it as a personal safety net, as long as you know where to find what you need.

The handbook functions as:

• A comprehensive formula reference covering foundational and specialized FE topics
• A reliable unit-conversion guide
• A quick source for explanations and definitions common across engineering disciplines
• A structured outline of all subject areas covered on each FE exam

Because it is the only reference material allowed during the exam, mastering its layout and content gives you a significant advantage.

During the exam:

• You are not allowed to bring your own notes
• You cannot print the handbook
• You cannot highlight or annotate the handbook
• You must use only the digital version provided on the exam computer

This ensures that every candidate uses the same standardized reference.

What does the handbook include?

The FE Reference Handbook is carefully organized by topic, not as a random collection of formulas. This structure makes it easier to navigate and quickly find what you need during the exam.

You’ll find coverage of the key FE subjects, including:

• Unit conversions
• Ethics and professional practice
• Safety principles and procedures
• Mathematics
• Engineering probability and statistics
• Chemistry and biology
• Materials science/structure of matter
• Statics
• Dynamics
• Mechanics of materials
• Thermodynamics
• Fluid mechanics
• Heat transfer
• Instrumentation, measurement, and control
• Engineering economics

Following the general chapters, the handbook covers discipline-specific content for:

• Chemical engineering
• Civil engineering
• Environmental engineering
• Electrical and computer engineering
• Industrial and systems engineering
• Mechanical engineering

Chapters will contain:

• Key engineering formulas
• Clear diagrams illustrating core concepts
• Important engineering constants
• Helpful tables and charts for fast reference
• Foundational theory and basic concepts

Because the chapters are organized by topic rather than alphabetically, familiarize yourself with the handbook’s chapter sequence and internal structure to navigate the exam efficiently.

How do you access the FE Reference Handbook?

It’s easy to access, but make sure you’re using the right version:

1. Download through NCEES: After creating a login, download the latest version directly from your NCEES account.
2. Check for updates: NCEES periodically revises the handbook, so study with the version used on your exam.
3. Practice with the digital format: On exam day, you will use the handbook as a searchable PDF. You cannot save personal notes or bookmarks as you can while studying, so develop your navigation habits in advance.

Getting familiar with the digital version in advance is essential. Keep the handbook open while working through practice questions and mock exams to develop strategies for finding answers quickly.

The benefits of knowing the handbook

A thorough understanding of the handbook can make the difference between passing and failing. Here’s why:

• Time-saver: Efficient searching can shave minutes off each question, time that really adds up over a 110-question exam.
• Reduces memorization: You don’t need to memorize complex formulas like Manning’s equation or soil-consolidation formulas; they’re already there.
• Prevents mistakes: Many FE errors result from using the wrong formula or unit. The handbook helps you double-check your work.
• Boosts confidence: When you know where everything is, the exam feels more familiar and less stressful.
• Guides your study plan: The handbook serves as a built-in syllabus, outlining exactly what NCEES expects you to know.

Used as both a study aid and a quick reference, the handbook trains you to work as efficiently as possible.

Using the handbook effectively while studying

Mastering the handbook should begin well before exam day. Make a habit of keeping it open whenever you work through practice questions. This repeated exposure builds the muscle memory you need to locate topics quickly during the test.

Spend time scrolling through each chapter to learn where specific subjects are located. For example:

• The book opens with core information on unit conversions, ethics, and safety
• Math, statics, and science basics appear early in the handbook
• Specialized topics are found later on

Overall, the handbook follows a broad-to-narrow structure, starting with general math and science before moving into discipline-specific topics. This organization mirrors the flow of the FE exam itself. Once you understand this progression, navigating the handbook becomes much easier and faster.

The digital search function is most useful when used strategically:

• Memorize and search high-yield keywords.
• Use single keywords or concise phrases for precise results.
• Recall section headers to jump to important topics.
• Avoid long sentences; use brief, targeted searches and practice under exam time constraints.

You cannot use “Control + F”; use only the built-in search tool in the navigation menu’s top-right corner (you can watch a short walkthrough to see how it works). Before test day, review the handbook’s structure, functionality, and content. Since you will not have time to read entire sections, know where each topic is located.

Outside exam conditions, feel free to make your copy your own:

• Add digital notes to your copy
• Bookmark frequently referenced pages
• Create a custom “top sections” list for quick access

For difficult topics, read the relevant section fully and take detailed notes. Its concise explanations reinforce key concepts and help you identify the most valuable pages.

Using the handbook effectively during the exam

On exam day, the handbook is your primary resource. Here’s how to use it effectively:

1. Don’t overuse search: Not every problem requires a search. For straightforward equilibrium or algebra questions, rely on your training.
2. Double-check before solving: If a formula seems unfamiliar, verify it in the handbook. This helps you avoid using the wrong version or overlooking a constant.
3. Keep it open the entire time: Switching between the test and handbook is quick, so don’t waste time reopening the file.

You don’t need to memorize every detail, but knowing where information is located and how it’s worded makes it much easier to find the answers you need.

Tips for mastering the handbook

Small habits make a big difference:

• Flip through the handbook for 10-15 minutes each day
• Work through practice problems with the handbook open
• Learn the keyword patterns NCEES uses
• Bookmark pages while studying, not during the exam
• Create a list of your “top 20 most-used formulas” and memorize where to find them
• Complete at least one full-length, timed practice exam using only the digital handbook

With consistent practice, you’ll navigate the handbook instinctively.

Final thoughts

Like an engineer in the field, you aren’t expected to know every formula or concept by heart. You’re expected to know how to find the answers when you need them. Once you’re comfortable using the FE Reference Handbook, the exam becomes much more manageable and far less intimidating. The more you practice with it, the more naturally it will come to you under time pressure.

By spending a little time each day learning how it’s organized, you’ll enter the FE exam feeling more confident, prepared, and equipped to succeed.
