PE Environmental Exam exam requirements & cost
Straight from the certifying body — separate from what we charge for the study portal.
The NCEES PE Environmental page describes an 80-question, computer-based exam delivered year-round at NCEES-approved Pearson test centers. The appointment lasts nine hours: a short nondisclosure agreement, a tutorial, the 8-hour exam and a 50-minute scheduled break. Questions are multiple choice plus alternative item types; the exam specifications list multiple correct (select all), point and click, drag and drop, and fill in the blank formats. The electronic reference handbook and any design standards the exam specifies are the only reference materials allowed during the exam; personal copies are not allowed. The exam specifications that took effect in April 2026 cover six knowledge areas: Water, Solid and Hazardous Waste, Sustainability, Air, Site Assessment and Remediation, and Environmental and Occupational Health. NCEES lists an exam fee of US$400, payable directly to NCEES. NCEES does not publish a passing score for the PE Environmental exam. The percent score in the portal mock is only a self-check, not a prediction of your result. The NCEES page lists the exam fee at US$400, paid to NCEES. Your licensing board may charge a separate application fee, and fees can change, so confirm the current amounts. NCEES describes the PE exam as designed for engineers with at least four years of post-college work experience; your state licensing board sets the actual requirements, so confirm them with the board. The portal is a practice aid built on the published specifications: it is not a copy of the exam, it does not simulate the alternative item types, and it does not predict your score.
