What you need to become a Professional Engineer

A Professional Engineer (PE) license lets you sign off on engineering work, take on clients directly, and use the title "engineer" legally in most U.S. states. The path has four main parts: a four-year engineering degree, work experience under a licensed engineer, passing the Fundamentals of Engineering (FE) exam, and passing the Professional Engineer (PE) exam. The whole process typically takes 8 to 10 years from the start of your degree.

Each state has its own licensing board and sets its own rules, so requirements vary by location. However, the National Council of Examiners for Engineering and Surveying (NCEES) writes the exams and sets a baseline that most states follow. If you move to a different state after licensing, you can usually transfer your license through a process called reciprocity, though some states require additional steps.

Key Takeaways

  • You need a four-year engineering degree from an ABET-accredited program, which ensures your school meets national standards for engineering education.
  • Most states require four years of work experience under a licensed PE, though some allow you to start the FE exam when ready after graduation.
  • You must pass the FE exam first, then after meeting experience requirements, pass the PE exam in your specific engineering discipline.
  • Your state's engineering licensing board handles registration and exam scheduling, not a federal office, so you contact them directly to begin.
  • The PE exam costs between $300 and $400 depending on your state, and exam fees are separate from process and registration costs.

Getting an ABET-accredited engineering degree

Your degree must come from a program accredited by ABET (Accreditation Board for Engineering and Technology). This accreditation means the program meets national standards for curriculum, faculty, and facilities. When you are choosing a school, check ABET's online directory to confirm the specific program you are interested in is accredited—not all engineering programs at a school are necessarily accredited, so verify the exact degree path.

The degree takes four years full-time and covers mathematics, physics, chemistry, and discipline-specific courses in your engineering field (civil, mechanical, electrical, chemical, and so on). Some schools offer five-year programs that combine the bachelor's degree with a master's, which can shorten your total time to licensure if your state allows it. You do not need a master's degree to get a PE license, though some engineers pursue one for career advancement.

Meeting the work experience requirement

After graduation, you need work experience under a licensed PE. Most states require four years, though a few allow three years if you have a master's degree. The work must be in engineering—design, analysis, construction oversight, or similar roles. Time spent in sales, management, or teaching does not count unless you are actively doing engineering work alongside those duties.

Your supervising PE does not have to be in the same discipline as you, but they do need to be licensed in your state or a state that recognizes reciprocity. Keep detailed records of your work: the projects you worked on, your specific responsibilities, the dates, and the name and license number of your supervising engineer. Some states require you to submit this record as part of your PE exam process, and gaps or vague descriptions can delay approval.

You can take the FE exam before you have completed your work experience—most people take it right after graduation—but you cannot sit for the PE exam until you have met the experience requirement and your state approves your process.

Passing the Fundamentals of Engineering (FE) exam

The FE exam is a computer-based test offered year-round at testing centers. It covers broad engineering topics: mathematics, physics, chemistry, materials science, thermodynamics, fluid mechanics, and ethics. The exam is six hours long with a break in the middle. You are allowed a reference handbook provided by NCEES, so you do not need to memorize formulas.

Registration happens through your state's engineering licensing board, not directly through NCEES. You pay a registration fee (typically $100 to $200) and an exam fee (typically $200 to $300). After you register, you receive an authorization to test, which you use to schedule your exam at a Pearson VUE testing center. Most people schedule their exam within a few weeks of registering.

Study materials include NCEES practice exams, review courses offered by universities and private companies, and textbooks focused on FE preparation. Many engineers spend two to four months studying. You receive your score when ready after the exam, and if you pass, your state's board is notified automatically.

explore for PE licensure and taking the PE exam

Once you have passed the FE exam and completed your work experience, you submit an process to your state's engineering licensing board. The process asks for your education history, work experience details, and references from engineers who supervised you. Some states require notarized documents; others accept digital submissions. Processing takes four to eight weeks.

After your process is approved, you become may be able to access to sit for the PE exam. Like the FE, it is computer-based and offered year-round. The PE exam is discipline-specific—you choose civil, mechanical, electrical, chemical, or another field—and is eight hours long with a lunch break. It focuses on practical engineering problems in your discipline rather than broad fundamentals.

The PE exam costs $300 to $400 depending on your state. You register through your state board, receive an authorization to test, and schedule at a Pearson VUE center. Most people study for three to six months using NCEES practice exams, review courses, and discipline-specific textbooks. After you pass, your state issues your PE license, which is valid for a set period (usually five to ten years) before renewal.

Finding your state's licensing board and starting the process

Each state has its own engineering licensing board, often called the State Board of Professional Engineers or the Department of Professional Regulation. You can find yours through NCEES's state board directory on their website, or by searching "[your state] professional engineer licensing board." The board's website lists current fees, process important date (if any), required documents, and contact information for questions.

Some states have specific process windows or important date; others accept applications year-round. A few states have additional requirements like a professional responsibility exam or specific coursework in engineering law. Starting with your state board's website saves time and prevents mistakes on your process.

Frequently Asked Questions

Can I take the PE exam without taking the FE exam first?

No. All states require you to pass the FE exam before you sit for the PE exam. A few states allow you to take both exams in the same testing window if you have already passed the FE, but you must have an FE passing score on record before the PE exam is graded.

What if my engineering degree is from outside the United States?

You can still get a PE license, but your degree must be evaluated by an approved credential evaluation service to confirm it is equivalent to a U.S. ABET-accredited degree. This evaluation costs $200 to $400 and takes several weeks. Some states also require additional work experience or an extra exam if your degree is from a country not on NCEES's list of substantially equivalent programs.

How much does it cost to get a PE license?

Costs vary by state but typically total $800 to $1,500 from start to finish. This includes FE registration and exam fees ($300 to $500), PE process fees ($100 to $300), and PE exam fees ($300 to $400). Study materials, review courses, and travel to testing centers are additional costs not set by the state.

Can I work as an engineer without a PE license?

Yes. Most engineering work does not require a PE license. You need one only if you sign engineering documents that the public relies on (like building designs or bridge plans), offer engineering services directly to the public, or work in a field where your state legally requires it. Many engineers work their entire careers without a PE license.

How long is a PE license valid?

PE licenses are typically valid for five to ten years depending on your state. Before expiration, you renew by paying a renewal fee (usually $100 to $300) and sometimes completing continuing education hours in engineering topics. Requirements vary by state, so check your state board's renewal rules.
