PE-AE Pass Rate 2026: What the Data Shows

What the Published Numbers Say

If you are searching for the Principles and Practice of Engineering - Architectural Engineering (PE-AE) pass rate, here is the complete official picture. NCEES, the body that develops and administers the exam, publishes two figures for the PE Architectural Engineering exam, last updated in January 2026:

That is all NCEES reports for this exam. There is no published breakdown by domain, by degree type, by employer, or by state, and you should be skeptical of any site that claims otherwise. Anyone quoting a precise "overall" figure, a rate segmented by discipline background, or a historical trend line for this exam is either inventing it or borrowing it from a different credential.

For context on how this fits into the larger licensure picture, see our companion piece on how hard the PE-AE exam really is, which looks at difficulty beyond the headline percentage.

Reading the Cohort: Why 89 and 16 Examinees Matter

The most important number in the pass-rate table is not a percentage. It is the cohort size. Architectural Engineering is one of the smaller PE disciplines, and the published sample is 89 first-time examinees and 16 repeat examinees.

What this means in practice:

• Do not over-interpret year-to-year changes. A shift of a few points in either direction can be noise.
• Do not treat 60% as your personal odds. Your preparation, your design experience, and your match to the blueprint matter far more than the cohort average.
• Do not assume the rate is stable. The January 2026 table reflects a cohort that sat before the exam specifications changed (more on that below).

First-Time vs. Repeat: The 60% and 31% Gap

The gap between 60% and 31% is the single most actionable pattern in the data, even allowing for the small repeat sample. Several PE-AE-specific reasons plausibly explain why repeat takers fare worse, and all of them point toward preparation strategy:

Repeat candidates often fail on breadth, not depth

The exam has no depth tracks. Unlike some PE disciplines where you choose a specialty module, every PE-AE candidate answers all questions across Electrical Systems, Mechanical Systems, Structural Systems, and Project Administration. A candidate who is a strong HVAC designer but thin on electrical power distribution or structural loads will feel that imbalance on every attempt. Re-studying the same strong area does not fix the weak one.

One administration per year compresses the feedback loop

The exam is offered on a single testing day annually. A failed attempt means a long wait, during which unused knowledge fades and work responsibilities pull candidates toward their day-to-day specialty. Repeat takers who simply "study more of the same" for twelve months often arrive with the same blind spots.

No partial credit and no published score

Items are scored with no partial credit, and NCEES reports only pass/fail, not a numerical score. If you do not pass, you do not get a score to diagnose. You have to reconstruct your weak areas from memory and from a self-audit against the blueprint. Our guide to the PE-AE passing score explains what NCEES does and does not disclose about scoring.

The October 2026 Blueprint Change and Your Odds

This is the part most pass-rate articles miss. The January 2026 pass-rate cohort predates the current exam specifications. The four-domain blueprint effective October 2026 applies to the next sitting and replaces the earlier October 2022 five-domain outline. The published pass rates therefore describe candidates who tested under the older structure.

What that means for you:

1. The 60% and 31% figures are not a prediction for the October 2026 exam. They are the most recent official data, but they were generated under a different outline.
2. Study materials built around the old five-domain outline may be misaligned. Verify that any resource reflects the four current domains.
3. The code editions are specified. The exam references the 2018 IBC, IECC, IFC, IMC and IPC; ASHRAE 62.1-2016 and 90.1-2016; NFPA 13, 14, 20 and 72 (2019), NFPA 70 (2017), and NFPA 101 (2018); ACI 318-2019; TMS 402/602-2016; the AISC Steel Construction Manual, 15th edition; ASCE 7-2016; and the NDS and Supplement 2018. Studying from the wrong edition is a classic way to lose points on a closed-book, reference-limited exam.

Where Pass/Fail Is Decided: Domain Question Counts

NCEES publishes question-count ranges per domain, not percentage weights, and we will not invent percentages. The ranges tell you where your preparation hours earn the most return:

Mechanical Systems has the largest range at 25-38 questions, followed by Electrical Systems at 23-35. Note that the 85 questions include unscored pretest items, so you cannot tell in the moment which questions count.

Because the Mechanical and Electrical ranges combine for a large share of the exam, a candidate who is weak in either is statistically exposed. Our PE-AE study guide shows how to sequence preparation across these four areas.

Exam Format Factors That Affect Results

Pass rates are not just about knowledge. The format imposes constraints that quietly lower scores for unprepared candidates:

• 85 questions in 8 hours 30 minutes of testing, within a 9-hour 30-minute appointment that includes a 2-minute nondisclosure agreement, an 8-minute tutorial, and a 50-minute scheduled break.
• Fixed-length, nonadaptive CBT. Every candidate sees a set of questions of the same length; the exam does not adjust to your performance.
• Multiple-choice plus alternative item types, with no partial credit. You must complete multi-step items correctly to earn the point.
• No penalty for wrong answers. Answer every question; never leave one blank.
• Closed-book with a searchable reference. You use the supplied PE Architectural Engineering Reference Handbook and the specified design standards only. The blueprint states that only one design-standard chapter can be opened and searched at a time, so navigation speed is a real skill.
• U.S. Customary units and NCEES-approved calculators only. There is no remote testing; you sit at an NCEES-approved Pearson test center.

Turning the Data into a Domain-Weighted Plan

This is the one place we will talk about scheduling, and it is tied directly to the blueprint rather than generic advice. Use question-count ranges to allocate time, and front-load your weakest large domain:

For practice, NCEES offers an official PE Architectural Engineering practice exam aligned to the October 2026 specifications (85 questions with solutions, including 16 new questions). Supplement it with original, domain-targeted questions, and take timed sessions on our PE-AE practice test platform. Our PE-AE cheat sheet is a quick way to confirm you have the key standards and editions straight before test day.

Eligibility, Fees, and Why One Attempt a Year Raises the Stakes

Pass rate is only meaningful if you can get to the testing chair. Eligibility and exam authorization depend on the licensing board you select. The common route is an EAC/ABET-accredited bachelor's degree, passing the FE and PE exams, and four years of acceptable, progressive, verified experience, though alternative routes and the permitted sequence vary by jurisdiction. Details are in our guide to PE-AE requirements and how to qualify.

On cost, the NCEES exam registration fee is $400, and a separate licensing-board application fee may apply. Because the exam is offered once a year, a failed attempt means paying again and waiting a full cycle, which is part of why the repeat figure matters. See the PE-AE certification cost breakdown for the full picture and the PE-AE exam dates guide for the October 28, 2026 administration.

If you are weighing whether the investment pays off, read Is the PE-AE certification worth it? for the ROI discussion. Remember that this is a licensure exam: the PE license itself, its validity, and renewal and CPC/PDH obligations are administered by your licensing board, not by NCEES.
