Introduction
License renewal deadlines have a way of sneaking up on you. When they do, the last thing you want is to discover your credits don’t count or that you’ve been tracking them in the wrong unit. Here’s everything engineers need to know about continuing education units (CEUs), how they compare to PDHs, and how to make sure your continuing education actually works for your renewal.
What are CEUs?
Continuing Education Units (CEUs) are a standardized unit of measurement for non-degree educational experiences required by various professional organizations. One CEU represents ten hours of participation in an approved program or course that meets specific academic standards. This means that if you have completed a 40-hour professional development course, you will receive four CEUs upon completion.
The American Council on Education (ACE) is responsible for developing guidelines and standards for awarding continuing education units (CEUs) across different professions. ACE defines one continuing education unit as consisting of at least 10 contact hours in a structured continuing education experience under responsible sponsorship, capable direction, and qualified instruction.
Professionals often seek accredited continuing education programs to ensure that their learning and training are recognized across various industries.
Importance of CEUs in Professional Development
Continuing education units are critical to maintaining professional competence and staying up-to-date with industry trends and best practices. The knowledge gained through continued learning helps individuals advance their careers by demonstrating their commitment to ongoing professional development. For some professions like engineering or nursing, continuous learning is mandatory as the industry evolves rapidly with new discoveries and technologies emerging regularly.
Earning CEUs demonstrates not just commitment but also proficiency in your skill set, which can increase your chances of getting promotions or higher-paying jobs. In addition to career advancement opportunities, continuing education units provide an opportunity for personal growth and self-improvement by allowing individuals to explore new topics that interest them outside their primary field of expertise.
How Continuing Education Units Work
CEUs aren’t handed out for casual reading or passive professional experience. To earn them, the learning activity has to meet specific criteria:
- Structured learning: The course must have defined learning objectives, a set duration, and a qualified instructor or recognized provider. Self-directed study through an accredited program qualifies; watching a random YouTube video does not.
- Approved providers: Credits must come from a provider that meets your state board’s or licensing body’s standards. At PDH-Pro, all of our courses are developed to meet those requirements, so you’re not guessing about whether your credits will count.
- Certificates and documentation: After completing a course and passing the required assessment (we require a 70% or better on our quizzes), you’ll receive a certificate of completion. That certificate is your proof of credit, so make sure to keep it.
- Course formats: CEUs can be earned through online self-paced courses, live webinars, in-person workshops, and professional conferences. Online courses have become the most practical option for working engineers who need flexibility.
PDH vs CEU vs Contact Hours
Most state engineering boards don’t use the term “CEU” at all. They use PDH (Professional Development Hour). One PDH equals one hour of qualifying instruction. That means a 10-hour course earns you 10 PDHs, but only 1.0 CEU.
The math isn’t complicated once you know the conversion, but it’s easy to accidentally misreport your credits if you’re not paying attention to which unit your board requires.
| Term | What It Means | Common Use |
| CEU | 1 CEU = 10 contact hours | General professional development; used across many industries |
| PDH | 1 PDH = 1 contact hour | Engineering-specific; used by most state PE licensing boards |
| Contact Hour | 1 hour of instruction | Base unit; sometimes used interchangeably with PDH |
Calculating your credits yourself: Add up all your instruction hours across completed courses, then divide by 10 to get your CEU total. Multiply that number by 10 (or just use the raw hours) to get your PDH count. For example: three 6-hour courses = 18 contact hours = 1.8 CEUs = 18 PDHs.
CEUs for Engineers
Most licensed Professional Engineers (PEs) are required to complete continuing education to renew their licenses; however, the exact terminology and requirements vary significantly by state.
- Many states require PDHs, not CEUs specifically
- Some states don’t mandate continuing education at all (though it’s still strongly recommended)
- States that require CE typically ask for anywhere from 15 to 30 PDHs per renewal cycle
- Some states require credits in specific topic areas, such as engineering ethics or state-specific laws and regulations
So why do engineers search for “CEUs” if most boards use “PDH”? Mostly because CEU is the more widely recognized term outside of engineering, and it’s often used loosely in course marketing. When you see a course advertised in CEUs, just apply the conversion: multiply by 10 to get the equivalent PDH count.

Does your employer cover it?
Many engineering firms and companies actively support their employees’ continuing education through tuition reimbursement, paid time off to complete courses, or covered memberships to professional organizations. If you haven’t asked, it’s worth checking with HR before paying out of pocket. Employer-sponsored CE is a win on both sides.
How to Earn CEUs or Equivalent Credits
There’s no shortage of ways to earn continuing education credit as an engineer. Here are the most common:
Online Courses
Online self-paced courses are by far the most popular option for working engineers. You can complete coursework on your schedule, whether that’s during a lunch break or a Sunday afternoon. Our catalog of 500+ accredited engineering courses covers everything from structural engineering and NEC updates to project management and sustainability.
Webinars
Webinars and live online events can count toward your total, provided the provider is approved. Check with your state board to confirm.
Conferences and Seminars
In-person conferences and seminars hosted by professional organizations like ASCE, ASME, or NSPE typically offer qualifying credit. Keep your attendance records and any certificates issued.
College Courses
University or college courses in engineering subjects may count, though the credit conversion varies.
Always verify that a course is approved for your specific state before enrolling. Some states maintain approved provider lists; others review credits on a case-by-case basis. Our state rules and regulations courses can help you stay current on what your board expects.
How to Track CEUs for License Renewal
If you’re ever audited by your state board, you’ll need documentation. Here’s what to track for every course you complete:
- Provider name
- Course title
- Date of completion
- Number of credits earned (in PDHs or CEUs, whichever applies)
- Topic area (especially relevant if your state requires ethics or specialty hours)
- Certificate of completion
How long should you retain records?
Retention requirements vary by state board, but a safe general rule is to keep documentation for at least five years, or for two full renewal cycles. Some states require longer.
Common Mistakes Engineers Make With CEUs and PDHs
Even experienced engineers slip up here. Watch out for these:
- Assuming CEUs and PDHs are always interchangeable without checking. They convert easily (1 CEU = 10 PDHs), but that doesn’t mean every course marketed in CEUs is automatically approved for your state’s PE renewal. Always verify.
- Taking courses that don’t qualify. Not every continuing education course counts toward PE renewal. The subject matter, provider accreditation, and course format all factor in. When in doubt, check your state board’s approved provider list.
- Failing to retain proof of completion. Completing a course matters. So does proving you completed it. Download and save your certificate as soon as it’s issued. Don’t rely solely on a provider’s database, as platforms change, companies shut down, and records get lost.
FAQs About Continuing Education for Engineers
What does CEU stand for?
CEU stands for Continuing Education Unit. It’s a standardized measure of non-degree professional education, where 1 CEU equals 10 contact hours of instruction.
How many hours are in 1 CEU?
One CEU equals 10 contact hours (hours of actual instruction). So a 5-hour course = 0.5 CEUs; a 30-hour course = 3.0 CEUs.
Are CEUs the same as PDH?
Not exactly. Both measure continuing education, but the units are different. 1 CEU = 10 PDHs. Engineers most commonly work with PDHs for PE license renewal purposes, though CEU is a broader and more widely recognized term across professions.
Do professional engineers need CEUs?
Most PEs need to complete continuing education to renew their licenses, but state boards typically use PDH terminology rather than CEU. Requirements vary by state, so check your specific board’s rules or explore our state renewal packages for a quick reference.
