PE-A&BE Salary Guide 2026: Complete Earnings Analysis

What a Salary Guide Can and Cannot Tell You

Most "salary guides" for engineering credentials recycle one big number and call it analysis. This one takes a different approach. The Principles and Practice of Engineering examination in Agricultural and Biological Engineering (PE-A&BE), administered by the National Council of Examiners for Engineering and Surveying (NCEES) with Pearson VUE as the testing provider, is a gateway to a professional license. It is not a job title with a single pay scale. Earnings depend on what you do with the license, who employs you, and how much responsibility you carry.

Because pay data shifts with every labor-market cycle, this guide does not quote a specific salary figure for licensed agricultural and biological engineers. The most reliable public reference is the U.S. Bureau of Labor Statistics page on Agricultural Engineers in the Occupational Outlook Handbook, which also describes how licensure fits into the occupation. Use it as your baseline, then layer on the career-specific factors below. For a broader look at whether the investment makes sense, see our ROI analysis of the PE-A&BE credential.

Why the PE License, Not the Exam Score, Drives Pay

NCEES does not publish a fixed passing score, and it does not impose a predetermined pass rate. Pass/fail rests on a psychometrically established scaled competency standard. That matters for salary planning in one important way: employers care that you are licensed, not how comfortably you cleared the bar. Your result is pass or fail, and your pay conversation starts the day your licensing board issues the license.

It is also worth being clear about what the credential actually is. A PE license is issued and maintained by a state licensing board, including continuing-education requirements. It is not a separately renewable national NCEES certification. That distinction affects your career economics: your license rights, seal authority, and renewal costs come from the board in the jurisdiction where you practice. If you want the fundamentals, our guide on what PE-A&BE is covers the basics, and the eligibility and prerequisites article explains how to qualify.

The experience expectation

NCEES describes the exam as designed for engineers with at least four years of post-college experience. This is a design intent, not a universal admission rule, since boards set their own requirements. In practice, the years you spend before licensure are the years you build the project record that later justifies higher pay and signature authority.

Who Hires Licensed Agricultural and Biological Engineers

The five exam domains hint at the breadth of the field, and that breadth is why compensation varies so much. Licensed professionals in this discipline tend to work across a handful of employer categories:

• Consulting engineering firms that design drainage, irrigation, stormwater, and agricultural facilities for private and public clients, where a stamp is a billable asset.
• Equipment and machinery manufacturers where product design, testing, and safety work lean on machinery-systems knowledge.
• Food and bioprocessing companies that need engineers for plant design, process improvement, and sanitation-minded layouts.
• Government agencies and conservation programs at federal, state, and local levels, where natural resources and environmental systems work is common.
• Agricultural producers and cooperatives that hire engineers for facility planning, water management, and energy systems.
• Universities and extension programs where licensure supports teaching, research, and outreach credibility.

For a closer look at the job landscape, our page on PE-A&BE jobs goes deeper into role types and what each expects from licensed engineers.

How the Five Exam Domains Map to Paid Work

NCEES publishes question ranges, not percentage weights, and the specification states that subsidiary knowledge areas are neither exclusive nor exhaustive. So do not read a salary signal into the ranges. They are still a useful map of where the profession spends its professional attention. Here is how each official domain connects to the kind of work that earns a stamp.

The Factors That Move Compensation

Rather than quote numbers we cannot verify, here is a qualitative comparison of the levers that typically separate lower and higher earnings among licensed engineers in this field.

The Cost Side of the Equation

Any honest earnings analysis weighs what you pay against what you may gain. The verified, exam-related costs are modest relative to a professional engineering salary, but they are not the only costs.

• NCEES examination fee: $400 per attempt.
• Licensing-board costs: application and licensure fees are separate and set by your board, so check your jurisdiction.
• Optional official practice exam: the NCEES PE Agricultural and Biological Engineering Practice Exam e-book is $59.95 (copyright 2023) with 85 practice questions and solutions, available through the NCEES exam-prep listing.
• Time off and preparation time: the appointment runs nine hours 30 minutes in total, so plan for the full day.

The exam is administered in person as a computer-based test once a year. The next published sitting is October 28, 2026. Follow your licensing board's approval and registration process before booking, because booking comes after board approval. Our complete pricing breakdown itemizes these expenses, and the exam dates and scheduling guide explains the sitting calendar.

Possible offsets

ASABE maintains a PE Exam Resources page that includes preparation guidance, member mentoring, and conditional incentives with application deadlines. These incentives are conditional and do not create automatic reimbursement eligibility, so read the terms. Many employers also cover exam and licensure costs, and it is worth asking before you pay out of pocket.

A Domain-Sequenced Plan for the October Sitting

The one planning decision that ties directly to earning potential is sequencing your preparation so you protect your investment of $400 and a full exam day. Because Common System Applications has the largest question range, front-load it. Then order the remaining domains by how much hands-on experience you already have, spending extra time where your project history is thin.

Remember that there is no partial credit and no deduction for wrong answers, so answer everything. An undisclosed number of questions are unscored pretest items, and NCEES does not reveal which ones, so treat every question as if it counts. For a fuller plan, see our first-attempt study guide, and when you are ready to test yourself, work through the PE-A&BE practice questions.

What the published pass data actually shows

NCEES's official pass-rate table, updated January 2026, reports 91% for 33 first-time examinees and 100% for one repeat examinee. These cohorts are very small and are not results of the October 2026 sitting, so do not read them as a prediction of your odds. Our pass rate analysis explains how to interpret small samples, and our difficulty guide covers what makes the exam demanding.
