Professional Engineering Registration

The U.S.-based Principles and Practice of Engineering (PE) licensing exam identifies individuals who can practice professional engineering in such a manner that will safeguard life, health, and property and promote the public welfare. The TMS Professional Registration Committee originated the PE exam and maintained it for more than 20 years.

In 2021, the responsibility for exam development transitioned from TMS to the National Council of Examiners for Engineering and Surveying (NCEES). Learn more about the exam and study resources below.

About Professional Engineering Registration

The Metallurgical and Materials Professional Engineering exam is used to determine those candidates who are minimally competent for professional registration. The intent of licensure is to identify those individuals who possess the necessary qualifications to practice engineering. Licensure is essential to the protection of public health, safety, and welfare in matters pertaining to engineering. Due to the licensing process, the public can have confidence in the professional competency and conduct of engineers. TMS had the lead role in establishing the exam and maintaining it for more than 20 years. The exam is now managed by the National Council of Examiners for Engineering and Surveying (NCEES) to register professional metallurgical and materials engineers in the United States. 

Exam Overview and Prerequisites

If you’re considering taking the exam, check with your state engineering board for eligibility. 

Exam Format

Starting in 2022, the Metallurgical and Materials PE exam uses computer-based testing (CBT). NCEES states that  CBT offers many benefits, such as enhanced security for exam content and more uniformity in testing conditions. All CBT exams are offered at approved Pearson VUE test centers. For more information, go to the NCEES website

In CBT, bringing reference material into the exam site is strictly prohibited. A supplied reference handbook will be available to examinees electronically during the exam. NCEES registered users are able to download the handbook prior to the exam at no cost.
