The Principles and Practice of Engineering (PE) - Industrial and Systems Engineering exam is a licensure examination administered by NCEES that assesses a candidate's competence to practice as a professional engineer in the industrial and systems engineering discipline. The exam consists of 124 questions delivered in a computer-based format, covering eight core knowledge areas: Engineering Economics, Facilities and Environmental Engineering, Human Factors, Industrial Management, Manufacturing and Production Systems, Modeling and Computation, Probability and Statistics, and Work Design. It is designed for engineers who have completed an accredited engineering degree, gained qualifying work experience under a licensed PE, and are ready to demonstrate the breadth and depth of their professional knowledge. Candidates typically include practicing industrial engineers, systems engineers, operations analysts, manufacturing engineers, and consultants seeking licensure to enhance their professional standing, meet state regulatory requirements, or pursue advanced career opportunities. Passing the exam signifies that the candidate has met a rigorous standard of engineering competence and is prepared to assume responsible charge of engineering work. The exam tests both theoretical understanding and practical application, requiring candidates to solve real-world problems that reflect the complexity and interdisciplinary nature of industrial and systems engineering practice.

A manufacturing plant calculates Overall Equipment Effectiveness (OEE) for a machine. During the measurement period, the machine was down for maintenance for 8 hours, but this maintenance was not scheduled. How should the 8 hours of maintenance downtime be treated in the OEE calculation?
An engineer is working with a power series that converges for all x in the interval (-1, 1). They need to integrate the series term by term from x = 0 to x = 0.5. Which condition must be satisfied for this term-by-term integration to be valid?
A manufacturing engineer is evaluating noise exposure for workers near a stamping press that produces brief, high-intensity impact sounds. According to OSHA occupational noise exposure standards, what is the maximum permissible peak sound pressure level for impulsive or impact noise?
A queuing system has a mean arrival rate of 10 customers per hour and a mean service rate of 12 customers per hour. Using Little's Law, what is the expected number of customers in the system if the expected waiting time in the system is 0.5 hours?
Exam insights and study advice
Licensure as a Professional Engineer is a legal credential that authorizes individuals to offer engineering services directly to the public and to sign and seal engineering documents. In industrial and systems engineering, this credential carries significant weight in sectors such as manufacturing, healthcare, logistics, government, and consulting, where safety, efficiency, and regulatory compliance are paramount. Earning the PE demonstrates a commitment to professional standards, ethical practice, and continuous learning. It can lead to increased earning potential, expanded career opportunities, and greater influence in decision-making roles. Beyond personal advancement, the PE credential protects public health, safety, and welfare by ensuring that only qualified individuals assume responsible charge of engineering work. For employers, hiring a PE signals confidence that the engineer has met a nationally recognized benchmark of competence. For the profession, licensed engineers uphold the integrity and credibility of industrial and systems engineering as a discipline that improves systems, processes, and outcomes across virtually every industry.
