The world is changing. Nearly every licensure and certification on the planet is shifting to digital. The implications of these changes are vast, but we’re going to focus on the effect this has on 2025 PE exam dates in particular.
Because of the industry-wide shift into digital testing, it’s more important now than ever to keep track of the dates and times these exams take place. So if you miss one date while pursuing certification as a Professional Engineer (PE), you will not be eligible for the PE license and won’t be able to start your engineering career.
2025 PE Exam General Info
In the U.S., engineers must be licensed at the state level by professional licensing boards to become a PE. The license is granted when candidates meet a number of requirements in experience, education, and exams— as outlined on the NCEES website.
The PE exam was developed by the National Council of Examiners for Engineering and Surveying (NCEES) to test for a level of competency in a particular engineering field or discipline. Before even taking the exam, engineers must have gained a minimum of four years work experience to be eligible.
But even after meeting the experience requirement, it’s still very important when registering for an upcoming exam to review your state’s unique approval and registration process. Registration for all computer-based exams is open year-round, while paper-based exams ends in February.

PE Exam Dates 2025
As the entire process continues its shift to digital, some PE exams are paper and pencil while others are computer-based. Ultimately, the entire NCEES infrastructure is in a conversion process.
Some exams are held only once a year while others can be taken year-round. Since this can get a little confusing, here’s a general breakdown of what happens when:

Year-round vs. Single-day PE Exams
You may have noticed that some computer-based tests (CBT) are administered year-round, while others are not. According to NCEES.org, this is so they can use what’s called a linear-on-the-fly (LOFT) algorithm to construct year-round exams, which makes cheating an impossibility.
What this means is that even though every candidate is required to answer the same number of questions on identical topics, no examinee will ever have the same set of questions. The algorithm works to assemble a unique exam within a specific framework (i.e. format, number questions, topic, etc.). It will also set each exam at the same relative level of difficulty.
Other computer-based PE exams use a different algorithm that’s more of a high-stakes testing model. This is the reason they are administered only once each year. In this case, all attendees will receive the exact same questions.
Regardless of which statistical model is used, the question formats remain the same. So don’t worry about having to study for a different kind of exam if you’re taking paper and pencil instead of digital, or vice versa. Any reputable professional engineering review course will help you learn what’s important to pass the test!
The Future for The PE Engineering Exam
As previously mentioned, it’s expected that the entire shift to digital exams will take another 4 years. It’s not a simple process and there is a lot at stake— so there’s no room for error. If you’re still unsure about specific dates, visit the NCEES schedule to see where your exam lies on the calendar. Even if you’re only somewhat concerned, take it from us: it’s better to be prepared and ready no matter what format the test is in!

Frequently Asked Questions (FAQ) on the PE Exam
PE exam disciplines that are available in a computer-based testing (CBT) format can be taken year-round. However, many disciplines are only offered in a pen and paper format and are only available on specific dates in April and/or October. You can see a list of these exams and their dates on the NCEES website.
The Principles and Practice of Engineering Examination is available at different times for different disciplines. Many of these disciplines only offer tests in April or October — check this page on the NCEES website to learn more — while others are available at all times of the year.
Your experience may differ from other students when taking specific disciplines of the PE exam. However, the three easiest disciplines for first-time takers to pass (based on NCEES pass rates) are the Industrial and Systems, Metallurgical and Materials, and Architectural exams.
PE exam fees vary depending on the specific test you are taking and the location in which you are taking it. The best way to find out how much your specific engineering exam is going to cost is to visit the NCEES website and check your region on their interactive map.
