For more information on the format of the exam and the topics covered, download the exam specifications for the 2018 PE Environmental exam (PDF).
PE exam specifications and design standards are posted 6 months before the exam administration. Updates for the April exams are posted in November, and updates for the October exams are posted in May.
The cost to take the PE exam varies from state to state (or foreign location). Depending on where you register, fees may be paid directly to NCEES, a state licensing board, or a designee of the board. Visit the engineering licensure section, and select your exam location for more information about your registration fees and payees. You may be prompted to contact your state licensing board (or foreign entity) directly.
Reference materials and exam prep
This pencil-and-paper exam is an open-book exam. You are allowed to bring bound reference materials, but they must remain bound during the exam. Loose paper may be bound with
- ring binders,
- plastic snap binders,
- spiral-bound notebooks,
- or screw posts.
No staples will be permitted. Sticky notes and flags are permitted only when attached to bound materials. More information is available in the NCEES Examinee Guide.
The Principles and Practice of Engineering (PE) Environmental exam is an open-book pencil-and-paper exam through October 2018. The PE Environmental Reference Handbook is a reference you may use on exam day. It contains charts, formulas, tables, and other information that may help you answer questions on the PE Environmental exam. However, it does not contain all information required to answer every question; theories, conversions, formulas, and definitions that examinees are expected to know have not been included.
This Handbook is intended solely for use on the NCEES PE Environmental exam. You may bring your personal copy of the Handbook into the exam room as long as it is bound and remains bound according to the policies in the NCEES Examinee Guide. Additional references that adhere to policies in the Examinee Guide are allowed in the exam room for the April and October 2018 exams.

Note—The PE Environmental exam will transition from pencil-and-paper to computer-based testing (CBT) in April 2019. At that time, the PE Environmental Reference Handbook will become the only resource material you may use during the CBT exam. Reviewing it before exam day will help you become familiar with reference information provided. You will not be allowed to bring a copy of the Handbook into the exam room. Instead, the CBT exam will include a PDF version of the Handbook for your use.
NCEES offers practice exams to familiarize you with the exam format and content. These practice exams contain questions that have been used on past exams and questions written just for study materials to give you extra practice.
