The PE Agricultural exam is a once-a-year 85-question CBT with a 9.5-hour appointment and a $400 NCEES fee. NCEES reported Jan 2026 pass rates of 91% for first-time examinees and 100% for repeat examinees, but the repeat sample was only one candidate. As of March 12, 2026, the content blueprint still uses the October 1, 2023 specifications; the notable current update is the ASABE standards set effective for exams beginning October 1, 2025.
About the PE Agricultural Exam
The NCEES PE Agricultural and Biological Engineering exam is an 85-question computer-based test designed for engineers with qualifying agricultural or biological engineering experience. The current blueprint, effective beginning October 1, 2023, covers five content areas: Common System Applications (19-29 questions), Natural Resources and Environmental Systems (15-23), Processing Systems (12-18), Facilities and Structures (12-18), and Machinery Systems (12-18). NCEES administers the exam once per year at Pearson VUE test centers.

Frequently Asked Questions
How many questions are on the PE Agricultural exam?
The official NCEES PE Agricultural and Biological Engineering exam contains 85 questions. NCEES notes that the CBT includes multiple-choice items and alternative item types, so candidates should be comfortable with more than one interaction style on exam day.
How long is the PE Agricultural exam?
The appointment time is 9.5 hours, with 8.5 hours of actual exam time plus the nondisclosure agreement, tutorial, and a scheduled break. Because the exam is offered only once per year, time management and early registration matter more than they do for year-round PE disciplines.
What is the pass rate for PE Agricultural?
NCEES updated the Agricultural and Biological Engineering pass-rate table in January 2026 to show a 91% first-time pass rate and a 100% repeat pass rate. Those numbers came from 33 first-time examinees and 1 repeat examinee, so the repeat percentage should be interpreted cautiously.
Did the PE Agricultural blueprint change for 2026?
As of March 12, 2026, NCEES has not published a new 2026 content-specification overhaul for this discipline; the current exam specification remains the version effective beginning October 1, 2023. The current standards packet was updated for exams beginning October 1, 2025, so candidates should study against that ASABE standards list.
What references are provided during the exam?
NCEES provides the PE Agricultural and Biological Engineering reference handbook and the specified ASABE standards as searchable PDFs inside the exam software. Personal copies are not allowed in the exam room, so successful candidates practice searching the official electronic references before test day.
What topics matter most on the PE Agricultural exam?
The largest official domain is Common System Applications at 19-29 questions, followed by Natural Resources and Environmental Systems at 15-23 questions. In practice, that means candidates should be fluent in pumps and fans, energy and mass balances, engineering economics, irrigation and drainage, open-channel flow, soils, and conservation-oriented water management.
