- The exam is 50 multiple-choice questions in 2 hours, closed-book, with a 70% passing score.
- First two-year term costs $400 in the US/Canada ($100 exam plus $300 certification); a retake is $100.
- Prep content follows four chapter headings from ACAC's CIAQM study guide, and no domain weights are published.
- Renewal requires $300 plus 40 credits: 10 for attesting to field activity and 30 for professional development.
The Credential at a Glance
The Council-certified Indoor Air Quality Assistant Manager credential is issued by the American Council for Accredited Certification (ACAC) as a vocational certification. It sits in ACAC's Indoor Air Quality Management program family and is aimed at people who administer or influence building air-quality decisions rather than people who perform hands-on field diagnostics all day. Think facility staff, property and asset managers, and risk-oriented personnel who need a defensible foundation in how indoor air problems arise and how they get managed.
This page condenses the facts you need into one reviewable sheet. If you want the conceptual background first, see What Is CIAQAM? or the plain-language explainer on what CIAQAM stands for. For a broader view of the program, the CIAQAM Certification overview is a good companion.

Exam Format in Numbers
The CIAQAM exam is a closed-book written examination delivered by computer. You get 50 multiple-choice items, each with at least four answer choices, and 2 hours to finish. That works out to roughly two and a half minutes per question on average, which is generous for a recognition-and-application exam but not so generous that you can afford to stall on a single item.
How the 70% Cut Score Works
The passing score is 70%, established with the modified Angoff method. In plain terms, subject-matter experts judge how a minimally qualified candidate would perform on each item, and those judgments are aggregated into a defensible cut score. The practical takeaway: the standard reflects minimum competence, not mastery of obscure trivia. On a 50-item exam, 70% means you need 35 correct answers. For a deeper treatment of how scoring is described, read CIAQAM Passing Score 2026, and for how demanding candidates find the test overall, see How Hard Is the CIAQAM Exam?
Results
Electronic scores are available immediately after you finish, so you leave the session knowing where you stand. ACAC's 2025 Exam Pass Ratio document contains no CIAQAM entry, so there is no published CIAQAM pass rate to cite. Our CIAQAM pass rate discussion explains what can and cannot be said from the available data.
The Four Preparation Domains
The CIAQAM candidate handbook prescribes ACAC's Council-certified Indoor Air Quality Manager Exam Study/Review Guide as preparation material. The four domain headings below mirror that guide's substantive chapter headings. They are unweighted preparation headings, not an official exam blueprint with published percentages, so treat all four as fair game and avoid betting your study time on a guessed weighting.
Domain 1: BASIC PRINCIPLES: THE "IAQ TRIANGLE"
This is the conceptual frame the rest of the material hangs on. The IAQ triangle organizes indoor air problems around the interplay of sources, the pathways and systems that move air and contaminants, and the building occupants affected.
- Be able to classify any scenario by its source, its transport mechanism and its receptors.
- Recognize that intervening at any corner of the triangle can change the outcome.
- Expect scenario questions that ask which element of a described problem is the root issue.
Domain 2: BASIC PRINCIPLES: INDOOR AIR CONTAMINANTS
This domain is the vocabulary-heavy one. You need working familiarity with the categories of contaminants found in buildings, where they typically originate, and how they relate to occupant complaints.
- Know contaminant categories well enough to match a described symptom pattern or source to a likely class of contaminant.
- Understand why source identification matters before choosing a response.
- Be comfortable distinguishing biological, chemical and particulate concerns at a conceptual level.
Domain 3: IAQ PROGRAM ADMINISTRATION
For an assistant-manager credential, this domain deserves extra attention. It covers how an organization manages indoor air quality as an ongoing program rather than a one-off fix.
- Think policies, roles and responsibilities, documentation, communication with occupants, and management of complaints.
- Expect questions that test judgment about who should do what and in what order.
- Connect program elements to risk management, since the credential's eligibility language centers on property, asset or risk management.
Domain 4: IAQ INVESTIGATIONS AND REMEDIATION
This domain addresses what happens when a problem is reported: how an investigation is structured and how remediation decisions follow from findings.
- Understand the logical flow from complaint to investigation to corrective action.
- Know why systematic investigation beats guesswork, and how remediation ties back to the source-pathway-receptor model from Domain 1.
- Be ready for sequencing and best-next-step questions.
Our CIAQAM Exam Domains guide unpacks each area in more depth. Note that the guide's appendix is excluded from this scope, so you do not need to memorize appendix material for the exam.
Fees, Terms and Renewal Math
Costs are split into an examination fee and a certification fee. Memorize the structure, because it explains every figure on the fee schedule.
| Fee Component | Amount (USD) |
|---|---|
| Examination fee | $100 |
| Certification fee | $300 |
| First two-year term, US/Canada | $400 total |
| First two-year term, outside US/Canada | $425 total |
| Retake | $100 |
| Renewal fee | $300 |
The retake fee equals the examination fee alone, which makes sense: you already hold no certification yet, so only the exam component repeats. For a fuller walk-through of what the total outlay looks like in practice, see the CIAQAM Certification Cost breakdown, and for a return-on-investment perspective, read Is the CIAQAM Certification Worth It?
Renewal Requirements
The credential is valid for two years. To renew, you pay $300 and earn 40 recertification credits. Those credits break down into 10 credits for attesting to continued field activity plus 30 hours of professional development. Keep documentation of your activities, because renewals can be audited. Recertification procedures are published by ACAC, so verify current details before your term ends.
Eligibility and Application Quirks
CIAQAM is not an open-enrollment exam. ACAC requires an online application, required email verifications, a passing exam result, and unanimous board approval. No training course is mandatory, so you are free to prepare however you choose. For a full treatment of qualifying, see CIAQAM Requirements 2026.
Who Qualifies
The basic eligibility idea is current relevant employment. The handbook accepts attested involvement in property, asset or risk management, or corporate policy making related to indoor air quality. There is an important caveat: the current application affidavit requires legal ability to work in your country of residence and current employment in property, asset or risk management, and it does not repeat the handbook's corporate-policy-making category. If you are relying on the policy-making route, confirm with ACAC how your situation will be treated before you pay anything.
Two Source Conflicts to Know
- Project sheets: The handbook uses generic project-sheet wording, but current instructions expressly exempt CIAQAM applicants from project sheets. Follow the current instructions.
- Application deadline: Current instructions allow six months to complete the process, including the examination, while the handbook states 90 days. Because the two disagree, plan to the shorter figure unless ACAC confirms otherwise in writing.
Key Takeaway
When the handbook and the current application instructions disagree, the current instructions generally reflect how ACAC processes applications today. But where a deadline is involved, conservative planning to the shorter 90-day window costs you nothing and protects you from a missed cutoff.

Kryterion delivers the exam by computer, either at a testing center or through online video proctoring. Choose based on your environment: a testing center removes home-network and room-compliance worries, while online proctoring saves travel.
- Testing-center ID: Bring two government-issued IDs, including one photo ID.
- Closed-book: No reference materials during the exam.
- Time: 2 hours for 50 questions.
- Score report: Electronic scores are available immediately.
Delivery policies are published on ACAC's exams page; check them for the current rules on online proctoring requirements before you book.
The Handbook's Reading List
Beyond the prescribed ACAC study guide, the handbook lists additional references. Treat these as a verified reading list rather than a content outline, since their detailed contents were not part of the retrieved material.
- Managing Indoor Air Quality, fifth edition (2011)
- EPA, Building Air Quality: A Guide for Building Owners and Facility Managers (1991)
- NIOSH, Respirator Selection Logic (2004)
The EPA guide is written for the same audience the credential targets, owners and facility managers, so it pairs naturally with the program-administration domain. The respirator selection document is a reminder that protective equipment decisions can surface in remediation contexts. For a structured plan that folds these resources in, our CIAQAM Study Guide walks through a first-attempt strategy, and the CIAQAM Training page discusses preparation options given that no course is required.
Sequencing Your Review by Domain
Because no domain weights are published, a balanced plan beats a clever one. The order below follows how the material builds on itself: concepts first, then administration, then applied investigation.
Domain 1: The IAQ Triangle
- Learn the framework until you can apply it to any scenario without notes.
- Start the prescribed ACAC study guide from its opening chapter.
Domain 2: Contaminants
- Build a one-page contaminant sheet: category, typical sources, typical complaints.
- Read the relevant sections of the EPA building air quality guide.
Domain 3: Program Administration
- Focus on roles, documentation and communication, since this is the assistant-manager core.
- Practice judgment-style questions about who acts first.
Domain 4: Investigations and Remediation, then Full Review
- Walk a complaint from first report to corrective action.
- Finish with timed 50-question sets in a closed-book setting using the CIAQAM practice tests.
Four weeks is a suggested pacing, not a requirement. If you work in facility management daily, you may compress Domains 3 and 4 and spend longer on contaminant vocabulary. If you are newer to the field, extend Domain 2.
Facts That Trip Candidates Up
Numbers That Get Mixed Up
- The exam fee ($100) and the retake fee ($100) match, but the certification fee is $300 and so is the renewal fee. Do not conflate exam and certification components.
- The renewal credits total 40, but only 30 are professional development hours; the other 10 are for attesting to field activity.
- Validity is two years, and the fee total of $400 covers that first term only, not subsequent ones.
Conceptual Mix-Ups
- The four domains are preparation headings from the CIAQM study guide, not a published CIAQAM percentage blueprint. Anyone quoting precise domain weights is guessing.
- The 70% cut score is a fixed standard, not a curve against other candidates.
- No training course is mandatory, but that does not mean no preparation is needed. The exam is closed-book and the material is broad.
Where the Credential Leads
Roles that match the eligibility language, such as property management, asset management, risk management and facility operations, are the natural home for this credential.
