FE vs PE Exam

Becoming a licensed professional engineer in the United States is not a single-step process—it requires passing two major milestones: the Fundamentals of Engineering (FE) exam and the Principles and Practice of Engineering (PE) exam. Both are developed and administered by the National Council of Examiners for Engineering and Surveying (NCEES), and together they form the backbone of the licensure pathway.

The FE exam is typically the first hurdle, taken by engineering students or recent graduates. It focuses on testing fundamental technical knowledge, covering a broad range of subjects taught in an undergraduate engineering program. According to NCEES 2024 data, the FE exam is six hours long and includes 110 questions, with first-time pass rates often above 70%.

The PE exam, on the other hand, is aimed at engineers who have gained professional experience, usually four years post-graduation. It assesses the ability to apply engineering concepts to practice, ensuring that licensed engineers can competently safeguard public health, safety, and welfare. Recent NCEES pass rate statistics show that first-time takers typically achieve between 50–75% pass rates, depending on discipline.

For engineering students and professionals planning their career path, understanding the differences between the FE and PE exams is essential. This article provides a detailed breakdown of how these two exams compare in terms of eligibility, exam content, structure, costs, and long-term career impact.

Key Takeaways

  • FE Exam is the first step: Taken by students or recent graduates to demonstrate mastery of fundamental engineering concepts.
  • PE Exam follows work experience: Typically requires four years of supervised engineering experience before eligibility.
  • Exam formats differ: FE is broad and general, while PE is discipline-specific and application-focused.
  • Pass rates vary: FE exams generally have higher pass rates than PE exams.
  • Career impact: Passing the FE qualifies you as an Engineer-in-Training (EIT), while passing the PE grants full professional engineer licensure.

Purpose and Role of the FE and PE Exams

The FE and PE exams are not just academic hurdles; they serve as critical checkpoints in an engineer’s journey toward professional licensure. Each exam plays a different role, targeting different stages of career development.

The FE Exam: Establishing Fundamentals

The Fundamentals of Engineering (FE) exam is designed to measure an engineer’s grasp of the foundational concepts acquired during their undergraduate studies. Passing this exam is often the first official step toward licensure.

  • Who takes it? Primarily senior undergraduate students or recent graduates from an ABET-accredited engineering program (though eligibility rules vary by state).
  • Why it matters: Passing the FE exam designates you as an Engineer-in-Training (EIT) or Engineering Intern (EI), depending on your jurisdiction. This designation signals that you have mastered the basics and are on the licensure track.
  • Role in career growth: While the FE itself does not grant independent practice rights, it demonstrates competency and is a prerequisite for moving on to the PE exam. Employers often view FE certification as a strong indicator of technical readiness and commitment to the profession.

The PE Exam: Proving Professional Competence

The Principles and Practice of Engineering (PE) exam represents the second milestone in the licensure process. Unlike the FE, which tests broad fundamentals, the PE focuses on discipline-specific knowledge and real-world application of engineering principles.

  • Who takes it? Engineers who have typically accumulated at least four years of qualifying work experience under the supervision of a licensed professional engineer.
  • Why it matters: Passing the PE exam grants the coveted Professional Engineer (PE) license, which allows you to:
    • Sign and seal engineering plans
    • Offer services directly to the public
    • Take legal responsibility for engineering work
  • Role in career growth: The PE license is often a requirement for higher-level positions, public-sector roles, consulting opportunities, and entrepreneurship in engineering services. It also enhances credibility, employability, and earning potential.

Why Both Exams Are Essential

Together, the FE and PE exams ensure that engineers are not only technically competent but also prepared to handle the ethical and practical responsibilities of protecting public health and safety. The FE validates the fundamentals; the PE certifies the ability to apply them in practice.

Exam Structure and Format

Both the FE and PE exams are administered by NCEES and delivered via computer-based testing (CBT) at Pearson VUE test centers. While both share similarities in delivery, they differ significantly in scope, structure, and the types of questions asked.

FE Exam Structure
