A PE license does not automatically transfer between states. Every U.S. licensing board issues its own license, and to practice in a new state you file a separate application through a process called comity, in which the receiving board reviews whether your original credentials are substantially equivalent to what it requires of its own applicants. If they are, you get a new license without repeating exams or refilling your experience clock. Most licensed engineers who prepare well can add a state in roughly two to four months.
How Comity Actually Works
Comity is a legal principle where one state’s board formally recognizes the standards enforced by another state’s board. You’ll hear “reciprocity” used as a synonym, but true reciprocity involves a specific mutual agreement between two jurisdictions, which is rare in engineering licensing. Comity is what governs nearly every PE transfer.
The test most boards apply is substantial equivalence. Boards look at whether your education, examinations, and professional experience are comparable to their local requirements at the time you were originally licensed. That timing detail matters. Licensing standards have evolved, and an engineer licensed decades ago under rules that no longer exist may face extra scrutiny if those older requirements fall short of the current state’s threshold. Boards examine the legislative framework of your original state, not just your individual credentials, to confirm that the system you came through was demanding enough.
What the New State Will Check
Boards look at three pillars: education, examinations, and experience.
- Education: Most boards require a bachelor’s degree from a program accredited by the Engineering Accreditation Commission of ABET. Non-ABET or international degrees trigger an extra evaluation step.
- Examinations: You need to have passed both the Fundamentals of Engineering exam and the Principles and Practice of Engineering exam administered by NCEES. Some states add their own law or ethics exam on top.
- Experience: The standard expectation is four years of progressive engineering work, usually gained under the supervision of a licensed PE. A handful of states treat supervised experience as a recommendation rather than a hard requirement.
On top of the three pillars, boards require professional references from licensed engineers who can speak to your competence and character. The typical range is three to five depending on the jurisdiction. Your current license also has to be in good standing. Pending disciplinary actions or unresolved complaints will stall or kill a comity application.
If Your Degree Isn’t ABET-Accredited
If your engineering degree wasn’t accredited by EAC/ABET when you graduated, you’re not shut out, but you have an extra step. NCEES offers a Credentials Evaluation that compares your coursework against its Engineering Education Standard to determine whether the degree is comparable to a typical U.S. engineering program. The evaluation costs $400 and is typically completed within 15 business days after purchase.1NCEES. Credentials Evaluations All documents must be official originals, and anything not in English needs a certified translation. Getting this done before you apply saves time, since many boards won’t process a comity application while an education question is unresolved.
The NCEES Record Does the Heavy Lifting
The single most useful tool for engineers planning to practice in multiple states is the NCEES Record. It’s a verified digital file that consolidates your academic transcripts, exam results, employment history, and professional references into one package that any U.S. licensing board can access. There is no charge to create the record and no annual renewal fee.2NCEES. Records Program
Setting it up means creating an online profile and asking your universities, former employers, and references to submit their verifications directly to NCEES. Once those third parties confirm the information, it stays in the system permanently. You update it as you gain experience or complete continuing education. The real payoff comes when you apply for your second, third, or tenth state license. Instead of contacting every university and former supervisor from scratch, you authorize NCEES to transmit your record electronically to the target board.
NCEES charges a fee each time it transmits your record. The first transmittal for a comity application is $175, and every transmittal after that costs $100.3NCEES. What Is an NCEES Record? Every licensing board in the United States accepts the NCEES Record, covering all 50 states, the District of Columbia, and U.S. territories.2NCEES. Records Program
Filing, Fees, and Timing
Once your NCEES Record is transmitted, or your manual verification package is assembled, you file a formal application with the target state’s board. Most boards have an online portal, though some still accept or require paper submissions. Application fees charged by the state board itself generally fall between $100 and $500, separate from any NCEES transmittal fees.
After you submit, board staff conduct an initial review before presenting your file to the full board at a scheduled meeting. Those meetings happen monthly or quarterly depending on the state, and that cadence is the biggest variable in your timeline. Total processing time from a complete submission to license in hand typically runs 10 to 14 weeks if nothing is missing. Requests for additional documentation can add a month or more. The most common cause of delay is thin experience documentation, so describe your project history in detail upfront.
When approved, you receive a new license number for that state. This is an independent license, not an extension of your original one. You’ll maintain it separately, including that state’s renewal and continuing education rules going forward.
State Law and Ethics Exams
Several states won’t issue a comity license until you demonstrate familiarity with local engineering law. This typically takes the form of a take-home or open-book exam covering the state’s engineering practice act, board rules, and professional ethics standards. The exams are separate from the national FE and PE exams and carry their own fees. Study materials are usually on the board’s website. Failing to complete a required ethics exam is a frequent reason otherwise complete applications sit unprocessed.
Temporary Practice Permits
If you need to start work in a new state before a full comity license comes through, many states offer temporary practice permits. These are typically limited to a single project and expire after a set period, often one to two years. An engineer who holds a current license in another state and has applied for comity licensure can usually qualify. Most states limit you to one temporary permit, so it isn’t a strategy you can repeat. Documents you seal under a temporary permit typically must reference both the permit number and your home-state license.
When Comity Is Denied
Comity applications do get denied. The most common reason is that your original licensing pathway doesn’t meet the new state’s substantial equivalence threshold. This happens most often with engineers licensed decades ago under less rigorous standards, engineers who received exam waivers in their original state, and engineers whose education doesn’t align with the new state’s requirements.
A denial doesn’t mean you can never practice in that state. You may need to take or retake an exam, provide additional experience documentation, or complete supplemental education to close the gap. Some boards will tell you exactly what’s missing and allow you to reapply once the deficiency is resolved. If you suspect your credentials might be borderline, contact the target board before filing. That call can save you an application fee and months of waiting for a predictable denial.
After You’re Licensed: Continuing Education and Firm Registration
A new state license is the start of an ongoing obligation. Nearly every state requires licensed PEs to complete a certain number of Professional Development Hours during each renewal cycle. NCEES recommends a baseline of 15 PDHs per calendar year, and most states follow that standard or something close to it. A few states require no continuing education for renewal; others require as many as 30 PDHs over a two-year period, sometimes with a portion mandated to come from ethics courses or approved providers. One PDH equals roughly one contact hour of instruction. Regular job duties don’t count.4NCEES. Continuing Professional Competency Guidelines Letting a license lapse because you missed a renewal deadline or fell short on hours can mean reapplying from scratch.
Your personal license authorizes you to practice, but if your firm offers engineering services in the new state, the firm itself may need separate authorization. Most states require engineering firms to obtain a Certificate of Authorization, which typically means designating a PE licensed in that state as the person in responsible charge and paying an application fee generally in the $50 to $150 range. Out-of-state firms opening a branch office often face additional steps, including registering with the state’s business division and showing that a locally licensed PE is physically present at the office on a regular basis. Solo practitioners and small firms are the ones most likely to be caught off guard when clients contract with a business entity rather than with them personally.
Military-Connected Engineers
Active-duty service members and military spouses often face frequent relocations that make multi-state licensure especially burdensome. A growing number of states have enacted laws that expedite professional license transfers for military-connected individuals. Provisions vary but commonly include temporary licenses, expedited application review, fee waivers, or automatic recognition of an equivalent out-of-state license. Check both the target state’s licensing board and your installation’s legal assistance office for applicable provisions before starting the standard comity process.
