CMCI Exam Dates 2026: Testing Windows, Deadlines & Scheduling

Why There Is No Fixed Exam Calendar

Candidates searching for "CMCI exam dates 2026" usually expect a list of fixed sittings, like the spring and fall windows used by some other credentials. That is not how the Council-certified Moisture Control Investigator pathway is described in ACAC's published materials. The credential is issued by the American Council for Accredited Certification (ACAC), certification decisions are made by its CMCI Certification Board, and the exam itself is delivered through the testing provider Kryterion, Inc. in either a testing-center or online video-proctored format.

Nothing in the issuer materials reviewed for this article establishes a named 2026 exam release or a published list of calendar windows. We checked the research for this article on October 6, 2026, and we are deliberately not inventing dates. What the published materials do describe is a sequence: you apply, the board reviews your eligibility, and only then do you move to examination. Your personal "exam date" is therefore the product of how fast you assemble a complete application and how the board's meeting cycle falls around it.

The Real Timeline: From Application to Exam Day

Because eligibility review precedes the exam, the practical question is not "which date do I register for?" but "how long until I am cleared to test?" The stages below follow ACAC's handbook and application materials in the order candidates experience them.

Stage 1: Confirm which eligibility route fits you

ACAC describes two routes. The first is a high-school diploma or GED plus two years of documented relevant moisture-control field experience. The second is a qualifying two-year postsecondary degree, or the equivalent of 15 qualifying science-related credits, plus at least one year of relevant experience. Relevant education fields include engineering, science, architecture, industrial hygiene and related sciences. Our full walkthrough is in CMCI Requirements 2026: Eligibility, Prerequisites & How to Qualify.

Stage 2: Assemble the application package

The package is the slowest part for most people. It includes:

• Four project sheets documenting your moisture-control work.
• Applicable education transcripts if you are using the education route.
• Application verifications, completed by email and electronic affidavit under current procedures.
• Employer affidavits, which the handbook requests.

One wording difference is worth knowing. The handbook describes the qualifying experience as consulting, while the current CMCI application form asks about moisture-control investigations. If your experience sits between those descriptions, plan to explain it clearly in your project sheets rather than assuming either label will be read loosely.

Stage 3: Examination and board review

ACAC's process includes both examination and a unanimous certification-board review. The board's meeting cadence is therefore a real input to your timeline, which is why the conflict between sources, discussed next, matters.

Where ACAC's Own Sources Disagree

This is the single most useful thing to understand about CMCI scheduling. ACAC's current application page and its Candidate Handbook describe overlapping procedures differently. We did not find an issuer statement resolving the differences, so the safest approach is to plan to the more conservative reading and confirm directly with ACAC before you pay or schedule.

Testing Center vs. Online Proctored Delivery

Once you are cleared to test, ACAC describes two delivery modes through Kryterion: a physical testing center or an online, video-proctored session. Both use randomized question and answer order, and both give immediate results. The choice affects scheduling flexibility more than anything else.

If you choose online delivery, treat the technical requirements as part of your scheduling checklist, not an afterthought. A shaky connection or a shared room is the most avoidable way to lose an attempt. For more on the online format, our related coverage is in the CMCI Study Guide 2026: How to Pass on Your First Attempt.

Fees and Timing: What You Pay and When

Fee mechanics shape your timeline because a failed attempt costs both money and weeks. The initial US/Canada fee is USD 500, made up of USD 100 for the examination and USD 400 for certification covering the first two-year term. ACAC's current official application quotes USD 525 outside the US/Canada. A retake is USD 100.

Exam-Day Rules: Format, Timing and Closed Book

The exam is 100 multiple-choice questions, each with at least four answer choices, and you have three hours. It is closed book. The passing criterion is 75%, set by the certification board using a modified Angoff method, and you receive your result immediately. For a precise explanation, read CMCI Passing Score 2026: Exactly What You Need to Pass.

Proctoring and identification

Follow ACAC and Kryterion instructions for identification and check-in, and do not substitute rules from other testing programs. Online candidates are video-proctored throughout, so your workspace, webcam position and connection must hold for the full three hours. Because closed-book conditions apply in both delivery modes, plan to rely on memory of the official references rather than lookup.

Pass score versus pass rate

Do not confuse the 75% criterion with a pass rate. The criterion is the score you need; the pass rate would be the share of candidates who achieve it. ACAC's 2025 Exam Pass Ratio document contains no CMCI row, and an omitted row is not a zero pass rate. We also do not substitute CMCC figures. Our analysis is in CMCI Pass Rate 2026: What the Data Shows, and the difficulty question is covered in How Hard Is the CMCI Exam? Complete Difficulty Guide 2026.

Retakes, Validity and the Renewal Clock

Your certification is valid for two years, so your first exam date also starts a renewal clock once certification is granted. Renewal costs USD 400 and requires 40 renewal credits (RCs): 10 for continued field activity plus 30 professional-development hours under current procedures. ACAC expects you to retain records for audit.

That has a scheduling implication: begin logging field activity and professional-development hours from the day you are certified, not in the final months. Candidates who treat renewal as a last-minute task tend to discover gaps in documentation too late to fix.

Sequencing Your Preparation Around the Nine Domains

Your study calendar should work backward from the date you expect to be cleared to test. ACAC's chart lists nine domain lines covering CMCI, and the handbook groups topics differently, with eight headings in total including the ACAC Code of Conduct. No percentage weights or domain question allocations are published, so do not assume any domain is "worth more." The nine domains are: The Science of Water; Site Drainage; Foundations; Walls, ceilings, and floors; Roofs and building envelope assemblies; Plumbing; HVAC; Structural Drying; and Project documentation. A fuller breakdown is in CMCI Exam Domains 2026: Complete Guide to All 9 Content Areas.

One sequencing approach that fits the way the domains build on each other, with ethics studied alongside as required additional knowledge:

Do not treat any short selection of highlighted study pages as exhaustive. The handbook's selected review pages supplement, rather than replace, reading the complete prescribed references. For a compact review, use the CMCI Cheat Sheet 2026: One-Page Review of Must-Know Facts, and when you are ready to test yourself, try the CMCI practice tests to gauge readiness before you schedule.

Scheduling Checklist

1. Verify your route. Match your background to the diploma-plus-two-years or education-plus-one-year route.
2. Collect documents. Four project sheets, transcripts if applicable, and employer affidavits.
3. Resolve the source conflicts. Confirm with ACAC whether the six-month or 90-day window governs you, and whether notarization applies.
4. Budget realistically. USD 500 initial in US/Canada, USD 525 outside, plus a USD 100 retake reserve.
5. Choose delivery mode. Testing center, or online with a compliant webcam, private room and 2 Mbps connection.
6. Study to the references. ACAC Code of Conduct, EPA guidance and the prescribed drying text.
7. Test readiness first. Take timed practice at our practice test hub before committing to a sitting.
8. Plan the renewal. Start logging RCs and keeping records from day one of certification.
