PE Registration: Exam Knowledge Areas
The Professional Engineering exam is used to determine those candidates who are minimally competent for professional registration. "Minimum competence," as measured by the examination components of the licensing process, is the lowest level of knowledge at which a person can practice professional engineering in such a manner that will safeguard life, health and property and promote the public welfare.
PE EXAM SPECIFICATIONS
The examination presents problems that require a variety of approaches and methodologies, including design, analysis, application, and operations. Some problems may require knowledge of engineering economics. The exam is comprised of all multiple-choice questions. Each question has one correct answer (the key) and three incorrect answers (distracters)-a total of four possible responses per question. There are a total of 80 questions on the exam, 40 questions are offered in the morning session and 40 questions are offered in the afternoon session. The knowledge areas specified below are examples of the kinds on the exam, but they are not exclusive or exhaustive categories.
The examination will include questions that are independent of the type of material and questions that are related to specific materials. The materials-specific questions will be distributed in the following three groups:
- Approximately 50% of the material-specific questions address ferrous materials, defined as stainless steel, cast iron, carbon steel and alloyed steel.
- Approximately 30% of the material-specific questions address light and nonferrous materials, defined as titanium and titanium alloys, aluminum and aluminum alloys, copper and copper alloys, intermetallic alloys, precious metals, refractory alloys, superalloys and other nonferrous metals.
- The remaining 20% of the material-specific questions address ceramics, polymers, composites and electronic materials, including glasses, functional ceramics, engineering ceramics, elastomers, thermoset, thermoplastic, composites, silicon, and other semiconductor materials.
