- The written exam has 50 multiple-choice questions, a 150-minute limit, and a 72% passing score; there is no separate field exam.
- Post-Work Evaluation is 68% of the blueprint, made up of two 34% tasks, so it deserves most of your review time.
- You need active BPI Energy Auditor (EA) certification to qualify, and losing EA status deactivates your QCI.
- The exam is closed-book except for BPI Standards and Standard Work Specifications supplied electronically through the testing site.
The QCI at a Glance
This page is a one-sitting review of the facts that matter for the BPI Home Energy Professional Quality Control Inspector (QCI), the residential-retrofit credential issued by the Building Performance Institute, Inc. (BPI). It is not the ASQ Certified Quality Inspector and not a general manufacturing inspection certificate. If you are still sorting out the terminology, start with What Is QCI? or What Does QCI Stand For?, then come back here.
The QCI is a small-scope microcredential built around one job: verifying that energy-efficiency retrofit work was done correctly, safely, and in line with program requirements. The inspector is the person who looks at the work after (and during) installation and decides whether it meets the standard.

Exam Format and Test-Day Rules
The Numbers
The exam is 50 multiple-choice questions in 150 minutes. That works out to an average of three minutes per question, which is generous. The time pressure on this exam comes less from the clock and more from careful reading: questions are scenario-oriented, and the wrong answer choices are often plausible actions that would be acceptable in a different situation. For a deeper look at the passing threshold, see QCI Passing Score 2026.
The passing score is 72%. Do not carry over older "70%" descriptions you may have seen in outdated materials; the 2026 BPI handbook governs current exam rules.
What You Can and Cannot Use
- Closed-book, with one exception: BPI Standards and Standard Work Specifications are supplied electronically through the testing site.
- Marked reference copies are prohibited. Do not plan on bringing annotated printouts.
- Scratch paper must be surrendered to the proctor for destruction at the end.
- Proctoring includes observation and audio/video recording.
Where and How You Test
BPI Test Centers deliver the exam using BPI-approved proctors. Each center sets and collects its own examination fees, so pricing varies by provider. Remote availability is also provider-specific: for example, Building Performance Center's October 1-31, 2026 written-exam listing offered Zoom or in-person testing. Always confirm the delivery format with your chosen center. For scheduling logistics, see QCI Exam Dates 2026.
Blueprint Weights: Where the Points Live
The official written-exam blueprint has three domains with published weights. These come from the BPI Quality Control Inspector Certification Scheme Handbook (revised August 26, 2026), and the underlying job-task analysis is the September 2023 NREL report (NREL/TP-7A40-85789). The handbook governs current exam rules.
| Domain | Weight | Approx. Questions on a 50-Item Exam |
|---|---|---|
| Domain 1: In-Process Evaluation | 20% | about 10 |
| Domain 2: Post-Work Evaluation | 68% | about 34 |
| Domain 3: Project Compliance and Completion | 12% | about 6 |
The question counts above are simple arithmetic applied to the published weights on a 50-question exam; treat them as a planning guide, not a guarantee of exact item counts on any form. The takeaway is unmistakable: Post-Work Evaluation carries more than two-thirds of the exam. It is made up of two tasks at 34% each, so each of those tasks alone outweighs In-Process Evaluation and Project Compliance and Completion combined.
For a full breakdown of what each content area covers, read QCI Exam Domains 2026: Complete Guide to All 3 Content Areas.
Domain 1: In-Process Evaluation (20%)
In-Process Evaluation
This domain covers inspection while retrofit work is underway, before measures are covered up or the crew leaves the site. The defining idea is timing: some work can only be verified while it is still visible and accessible.
- Recognizing which installed measures must be inspected before they are concealed
- Identifying work that deviates from the scope, specifications, or standards while there is still time to correct it
- Documenting findings clearly so a contractor knows exactly what to fix
- Spotting safety concerns that arise during the job, not just at completion
At roughly 20% of the exam, expect around ten questions here. The reasoning pattern is "what should the inspector check or require right now, given what is happening on this job?" Answers that rely on waiting until final inspection are often wrong when the item at issue will be hidden by then.
Domain 2: Post-Work Evaluation (68%)
Post-Work Evaluation (two 34% tasks)
This is the heart of the exam. Post-work evaluation is the inspector's verification that completed retrofit work meets applicable standards and that the home is safe and performing as intended. Because it is split into two equally weighted tasks, you should expect two distinct clusters of questions inside this domain, each worth about a third of the whole test.
- Verifying that completed measures match the specified scope and applicable BPI Standards and Standard Work Specifications
- Evaluating installed work quality and identifying deficiencies that require correction
- Confirming health and safety conditions after the work is finished
- Interpreting inspection results and deciding whether work passes, needs rework, or needs further investigation
- Recording results accurately and consistently
This domain rewards candidates who can think like an inspector rather than a installer. An installer asks "did I do the work?" An inspector asks "can I confirm, against the standard, that the work is correct and the house is safe?" Because the standards are available electronically during the exam, the winning skill is applying them to a described situation, not reciting them from memory.
Key Takeaway
If you can only master one domain, master Post-Work Evaluation. At 68% of the blueprint, a strong showing here can carry you toward the 72% passing score, while a weak showing makes passing very hard no matter how well you do elsewhere.
Domain 3: Project Compliance and Completion (12%)
Project Compliance and Completion
The smallest domain deals with the program-level and administrative close of a project: confirming that the job meets program requirements and that the project is properly wrapped up.
- Checking that required documentation is complete and consistent with the work performed
- Confirming the project satisfies the applicable program or standards requirements
- Understanding what must be in place before a project can be considered complete
- Communicating results and outstanding items to the right parties
At about six questions, this domain is easy to underestimate. Because it is small, it is tempting to skip it, but six questions is roughly twelve points of your possible score, and candidates who ignore it often lose easy marks on documentation and closeout logic. A short, focused review is the right investment.
Eligibility and the Energy Auditor Dependency
QCI is not a stand-alone starter credential. You must hold active BPI Energy Auditor (EA) certification, and you will need to provide proof when scheduling. BPI does not mandate any particular preparation course, so training is optional from a requirements standpoint. For a full walkthrough of qualifying, see QCI Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Do not confuse the two exams. The Energy Auditor credential has field-exam requirements; the QCI does not. There is no separate QCI field examination. One published provider listing even includes Energy Auditor field-exam boilerplate alongside its QCI written-exam offering, but that language does not override the QCI handbook or create a QCI practical assessment.
Fees and Money Facts
There is no single national initial-exam fee set by BPI for the QCI. Because each BPI Test Center sets and collects its own examination fees, what you pay depends on where and how you test and whether training is bundled. The figures below are verified provider examples for specific packages, not interchangeable quotes for the same service.
| Provider Example | What the Price Covers | Listed Price |
|---|---|---|
| INCAP / Intelligent Weatherization | Out-of-network QCI written exam | $350 |
| Green Training USA | Training plus the written exam | $825 |
| Green Training USA | Written-exam retest / recertification | $475 |
Notice what is being compared: an exam-only price, a training-plus-exam bundle, and a retest price. They are different products. Training-course hours are also not exam timing; the exam itself is 150 minutes regardless of how long any course runs. For the full picture, including training, retakes, and renewal, see QCI Certification Cost 2026: Complete Pricing Breakdown. If you are weighing whether the spend makes sense, Is the QCI Certification Worth It? and the QCI Salary Guide cover the return side.
Five-Year Validity and Renewal Math
A QCI certification is valid for 5 years. Renewal has two prerequisites that must both be satisfied:
- Active EA certification at renewal time.
- Either at least 6 qualifying QCI-aligned CEUs earned during the active five-year cycle (which lets you bypass the written exam) or a passing score on the current QCI written exam.
You also submit the applicable renewal application and payment. For a single-certification renewal where no examination is required, BPI's public renewal schedule lists $360 by ACH, debit, or e-check, or $370.80 by credit card. If you must retest, examination charges are additional.
Facts Candidates Commonly Mix Up
Because several credentials in the energy and quality worlds share similar names or acronyms, the most common errors are importing the wrong credential's facts. Keep these straight:
| Common Confusion | The Correct QCI Fact |
|---|---|
| "There's a field exam like the Energy Auditor." | No. The QCI has a written exam only. |
| "The passing score is 70%." | The current passing score is 72%. |
| "The exam fee is set by BPI nationally." | Each BPI Test Center sets and collects its own fees. |
| "Course hours equal exam time." | The exam is 150 minutes; course length is separate. |
| "I can bring my annotated standards." | Marked reference copies are prohibited; only electronically supplied standards are available. |
| "QCI stands alone." | It requires, and depends on, active EA certification. |
| "It's the same as the ASQ inspector certificate." | No. This is BPI's residential-retrofit credential. |
To see how this credential fits into the wider job market, QCI Jobs describes the roles that use it, and QCI Training covers preparation options.
A Domain-Weighted Review Sequence
Rather than a generic schedule, let the blueprint set your calendar. A sensible allocation gives the biggest share of time to the domain that carries 68% of the exam.
Orientation and Domain 3
- Re-read the exam format rules and test-day restrictions
- Cover Project Compliance and Completion while the material is light and quick to learn
- Practice navigating the BPI Standards and Standard Work Specifications
Domain 2, First Task
- Work through post-work verification scenarios against the standards
- Focus on deciding pass, rework, or investigate
Domain 2, Second Task
- Cover the second 34% task cluster with the same scenario-driven approach
- Drill health and safety judgment calls
Domain 1 and Full Practice
- Review In-Process Evaluation, emphasizing what must be inspected before it is concealed
- Take timed practice sets and review every miss
For a fuller plan, see the QCI Study Guide 2026, and use the QCI practice tests to check your readiness under timed conditions. If you are unsure how much preparation you need, How Hard Is the QCI Exam? and QCI Pass Rate 2026 are useful reads, though note that BPI does not publish a pass rate that this article can cite.
Key Takeaway
Spend your hardest study hours on Post-Work Evaluation, then use the remaining time to cover the other two domains. Finish by taking a full timed run through the practice exam so the 50-question, 150-minute format feels routine on test day.
