What happens when your engineer license has been inactive for more than three years
If your professional engineer (PE) license has been inactive for more than three years, most state licensing boards will not let you straightforward renew it. Instead, you will need to go through a reinstatement process that is more involved than a standard renewal. The exact requirements depend on your state and the specific board that issued your license, but the general path involves demonstrating current competency, meeting continuing education requirements you may have missed, and sometimes passing an exam or providing evidence of recent engineering work.
The reason for this stricter process is straightforward: after three years away from active practice, state boards want assurance that you have kept up with changes in engineering standards, codes, and technology. A license that has lapsed for years represents a gap in your professional currency, and boards treat reinstatement differently than a routine renewal.
Key Takeaways
- Most states require you to complete all continuing education hours you missed during your inactive period, not just current-year hours.
- You may need to pass a jurisprudence exam or professional practice exam to show you understand current state laws and engineering ethics.
- Some states require proof that you have worked as an engineer recently or have a job offer lined up before reinstatement is granted.
- The reinstatement fee is typically higher than a standard renewal fee and varies by state.
- Processing time for reinstatement can take several weeks to several months, depending on your state board's workload and completeness of your process.
Continuing education requirements for lapsed licenses
The first hurdle in most reinstatement cases is continuing education (CE). When your license was active, you were required to complete a set number of CE hours every renewal period—often 30 to 40 hours per two-year cycle, though this varies by state. When you go inactive, those requirements do not disappear; they accumulate.
If your license has been inactive for five years, for example, you may owe two full cycles of CE credits—roughly 60 to 80 hours depending on your state. Some states allow you to complete these hours before you formally explore for reinstatement; others require you to submit proof of completion as part of your reinstatement process. Check your state board's website or contact them directly to learn whether they want the CE done first or submitted with your process.
CE courses must come from approved providers—typically engineering societies, universities, or professional development companies that your state board recognizes. Taking random online courses will not count. The board will want documentation showing the course title, provider name, date completed, and number of hours earned. Keep all certificates and transcripts until your reinstatement is fully processed.
Exams and competency assessments you may need to pass
Many state boards require reinstatement candidates to pass a jurisprudence exam or professional practice exam before the license is restored. This is not the same as the PE exam you took years ago. A jurisprudence exam focuses on your state's specific engineering laws, ethics rules, and regulations. It is usually shorter—often 50 to 100 questions—and can be taken online or at a testing center.
Some states go further and require you to retake the full PE exam if your license has been inactive for a very long time (sometimes seven years or more). This is less common for the three-to-seven-year range, but it is possible. A few states offer an alternative: they will waive the exam if you can show recent, continuous engineering work or a current job offer in your field.
Before you spend time and money preparing for an exam, contact your state board and ask exactly what exam, if any, is required for your situation. The requirements can differ based on how long you have been inactive and what type of engineering work you did before.
Proof of recent engineering work or employment
Some state boards want to see that you have not been completely disconnected from engineering. They may ask for proof of recent work experience—letters from employers, project documentation, or a current job offer showing that you are actively working as an engineer or about to be.
If you have been working in engineering during your inactive period, gather documentation: employment letters, project reports, performance reviews, or contracts. If you have a job offer waiting for your license to be reinstated, that letter counts too. If you have been out of the field entirely, some boards will still reinstate you, but you may face additional requirements like the full PE exam or an extended CE program.
The purpose here is not to punish you for time away, but to confirm that you are genuinely returning to practice and not just collecting a license you will not use. Be honest about your situation when you contact the board; they have seen many reinstatement cases and understand that people take breaks for various reasons.
The reinstatement process and fees
Once you have completed your CE hours and any required exams, you will submit a reinstatement process to your state board. This is different from a renewal form. The process typically asks for your license number, the reason for the lapse, what you have done to meet reinstatement requirements, and sometimes a statement about your intent to practice.
Reinstatement fees are usually higher than renewal fees. A standard PE renewal might cost $100 to $300, while reinstatement can run $200 to $500 or more, depending on your state. Some boards charge a flat reinstatement fee; others charge the renewal fee plus a reinstatement surcharge. Check your state board's fee schedule before you submit your process so there are no surprises.
Submit your process along with proof of completed CE hours, exam results, and any other documents the board requested. Keep copies of everything you send. Many boards now accept online applications and uploads, but some still require paper submissions. Your state board's website will specify the method.
Timeline and what to expect after you explore
Processing time for reinstatement varies widely. Some state boards process applications in two to four weeks; others take two to three months. Factors that affect speed include how busy the board is, whether your process is complete on the first submission, and whether the board needs to verify your CE credits or exam scores with third parties.
After you submit, you will typically receive a confirmation that your process was received. If the board finds anything missing or unclear, they will contact you and ask for additional information. This is normal and does not mean your process is denied—it just means the review process is not finished. Respond promptly to any requests from the board.
Once the board approves your reinstatement, you will receive a new license certificate or a letter confirming your active status. Some states issue a new license number; others restore your original number. You may be able to read a temporary license verification while you wait for the physical certificate to arrive. Check with your board about how they handle this.
Differences between reinstatement and reactivation
Some states use the term reactivation instead of reinstatement, or they use both terms for slightly different situations. Generally, reactivation is a faster, simpler process for licenses that have been inactive for a shorter time (often one to three years), while reinstatement is the more rigorous path for longer lapses. A few states have a middle ground: licenses inactive for three to five years may follow one set of rules, and licenses inactive for five years or more follow another.
Do not assume your state uses the same terminology or timeline as a neighboring state. Your state board's website will clarify which process applies to you. If the website is unclear, call the board directly—staff can tell you in minutes whether you need reinstatement or reactivation and what the specific requirements are.
Frequently Asked Questions
Can I practice engineering while my reinstatement process is being reviewed?
No. You cannot legally practice as a professional engineer or use the PE title while your license is inactive, even if your reinstatement process is pending. If you need to work in engineering during the review period, you may need to work under the supervision of an active PE or in a role that does not require licensure. Once your reinstatement is approved, you can practice independently again.
Do I have to retake the PE exam to get reinstated?
Not always. Most states do not require the full PE exam for reinstatement if your license has been inactive for three to seven years. However, you will likely need to pass a jurisprudence or professional practice exam. If your license has been inactive for ten years or longer, some states do require the full PE exam. Contact your state board to confirm what applies to you.
What if I completed some continuing education hours while my license was inactive—do those count?
It depends on your state's rules. Some states allow CE hours earned during the inactive period to count toward reinstatement requirements. Others do not. Your state board can tell you whether hours you already completed will be credited or whether you need to start fresh with new CE courses.
Can I reinstate my license if I have been working in a different field?
Yes, but you may face additional requirements. If you have been away from engineering entirely, the board may require you to pass the full PE exam or complete an extended CE program to demonstrate that you are current with engineering practice. If you have been working in a related field or have kept up with engineering through other means, explain this in your reinstatement process.
How much does reinstatement cost?
Reinstatement fees vary by state and typically range from $200 to $500, though some states charge more. This usually includes the reinstatement fee itself plus the renewal fee for the new license period. Add the cost of any CE courses and exam fees on top of that. Check your state board's website for the exact fee schedule before you explore.
