If you’re planning to become a licensed Professional Engineer (PE), one of the first questions you’ll likely ask is: How long does it take to get a PE license?
The short answer: most candidates spend about 8–12 years from starting college to earning their PE license.
The longer answer depends on your education path, work experience, and how quickly you pass required exams. Below, we’ll break it all down so you can understand what to expect—and how to move through the process efficiently.
What Is a PE License?
A Professional Engineer (PE) license is a state-issued credential that allows engineers to:
- Sign and seal engineering plans
- Offer services directly to the public
- Take on leadership and supervisory roles
- Increase credibility and earning potential

Typical Timeline to Get a PE License
Here’s a high-level look at the standard path:
| Step | Time Required |
| Earn a bachelor’s degree in engineering | 4 years |
| Pass the FE (Fundamentals of Engineering) exam | 0–6 months prep |
| Gain qualifying work experience | 4 years (typical) |
| Pass the PE exam | 2–6 months prep |
| Apply for licensure | 1–3 months |
Total Estimated Time: 8–12 years
Step-by-Step Breakdown
1. Earn a Bachelor’s Degree (About 4 Years)
Most states require a degree from an ABET-accredited engineering program.
Key details:
- Full-time students typically finish in 4 years
- Some accelerated or transfer pathways may shorten this slightly
- Without an accredited degree, you may need additional years of experience
2. Pass the FE Exam (During or After College)
The Fundamentals of Engineering (FE) exam is usually your first licensing milestone.
- Many students take it in their senior year
- Passing earns you the title Engineer in Training (EIT) or Engineering Intern (EI)
- Prep time varies, but most spend:
- 2–6 months studying
- 100–300 total study hours
3. Gain Work Experience (Typically 4 Years)
This is often the longest phase.
Requirements generally include:
- 4 years of progressive engineering experience
- Work supervised by a licensed PE
- Demonstrated growth in responsibility and technical skill
Some variations:
- Advanced degrees (like a master’s) may reduce the experience requirement in certain states
- Non-accredited degree holders may need 6–8 years of experience
4. Pass the PE Exam
Once eligible, you can sit for the Principles and Practice of Engineering (PE) exam.
- Discipline-specific (civil, mechanical, electrical, etc.)
- Typically requires:
- 2–6 months of preparation
- Focused review of real-world engineering applications
5. Apply for Licensure
After passing the PE exam, you’ll submit your application to your state board.
This usually includes:
- Verification of work experience
- Professional references (often from licensed PEs)
- Application fees and documentation
Processing time:
- Typically 1–3 months, depending on the state
Can You Get a PE License Faster?
In some cases, yes—but there are limits.
Ways to potentially shorten the timeline:
- Take the FE exam before graduating
- Start working under a PE immediately after college
- Choose employers who support licensure (mentorship, exam prep)
- Pursue a master’s degree (may reduce experience requirements in some states)
What you can’t skip:
- Required work experience (in most states)
- Passing both the FE and PE exams
Factors That Can Affect Your Timeline
Your path may be shorter or longer depending on:
Education Background
- ABET-accredited degree → fastest route
- Non-engineering or non-accredited degree → longer experience requirements
Career Path
- Working under a PE vs. not
- Type of engineering discipline
- Access to qualifying projects
Exam Readiness
- Passing exams on the first attempt vs. retakes
- Study time and preparation quality
Timeline Variations by Scenario
Here’s how timelines can differ:
| Scenario | Estimated Time |
| Traditional path (ABET degree + 4 years experience) | 8 years |
| With master’s degree (reduced experience in some states) | 7–9 years |
| Non-accredited degree | 10–12+ years |
| Career switch into engineering (assuming part-time degree completion) | 10–15 years |
Is It Worth the Time?
While the process takes several years, earning a PE license can open doors to:
- Higher earning potential
- Leadership roles
- Independent consulting opportunities
- Greater job stability and credibility
For many engineers, it’s a long-term investment that pays off throughout their careers.
Frequently Asked Questions About PE Licensure
How long does it take to get a PE license after passing the FE exam?
In most cases, it takes about 4 years after passing the FE exam to qualify for the PE exam. This time is spent gaining required work experience under a licensed Professional Engineer.
Can you take the PE exam before completing work experience?
It depends on the state.
- Some states allow you to take the PE exam before completing your work experience
- Others require you to finish all experience requirements first
Even if you pass early, you won’t receive your license until all experience requirements are met.
What is the fastest way to get a PE license?
The fastest path typically includes:
- Earning an ABET-accredited bachelor’s degree
- Passing the FE exam during your senior year
- Gaining continuous, qualifying work experience under a PE
- Passing the PE exam on your first attempt
Even on the fastest track, most candidates still need around 8 years total.
Can a master’s degree shorten the timeline?
Sometimes.
- Some states allow a master’s degree in engineering to count toward experience requirements
- This may reduce the required work experience by up to 1 year
However, this varies by state licensing board, so it’s important to check local requirements.
Do you need a PE license to work as an engineer?
Not always.
You can work in many engineering roles without a PE license, especially:
- Entry-level positions
- Roles in private industry (e.g., manufacturing, tech)
However, a PE license is typically required if you want to:
- Offer engineering services directly to the public
- Sign and seal engineering documents
- Advance into certain leadership or consulting roles
What happens if you fail the PE exam?
You can retake the exam.
- Most states allow multiple attempts
- You may need to wait until the next testing window (depending on the exam format)
- Additional study time (2–6 months) is usually recommended before retaking
Is the PE license valid in every state?
No—PE licenses are issued at the state level.
However:
- Many states offer licensure by comity (reciprocity)
- This allows licensed engineers to apply for licensure in another state without repeating the full process
Requirements vary, but having a PE license in good standing makes it easier to expand your credentials.
How long does it take to get a PE license if you didn’t study engineering?
It can take longer.
- You may need to complete additional coursework
- Most states require more years of work experience (often 6–8 years or more)
- You’ll still need to pass both the FE and PE exams
Total timelines can range from 10–15 years, depending on your background.
