CEAI Exam Dates 2026: Testing Windows, Deadlines & Scheduling

Why There Is No Fixed 2026 Exam Calendar

Candidates searching for "CEAI exam dates 2026" often expect a list of national test days, the way some credentials publish quarterly windows. For the Council-certified Environmental Allergen Investigator credential, administered through the American Council for Accredited Certification (ACAC), the public handbook and examination pages we reviewed do not describe a fixed annual calendar of testing windows. Instead, the exam is delivered by Kryterion, Inc. as a computer-based test, and your date is driven by when your application clears and when you book a slot with the testing provider.

That distinction matters for planning. You are not racing a single registration cutoff in the spring or fall. You are managing a sequence of gates: documenting your experience, getting your application accepted, and then scheduling and sitting for the exam within the allowed completion period. If you are still deciding whether you qualify at all, start with our breakdown of CEAI requirements, eligibility, and prerequisites before worrying about calendar logistics.

The Real Timeline: Application, Approval, Scheduling

Because there is no published test calendar, your personal timeline is built from the certification process itself. Certification requires experience verification, passing the examination, and unanimous board approval as separate requirements. There is also no mandatory training course, so you will not be waiting on a class cohort to start.

Step 1: Build your application package

Eligibility comes in two main routes. The first is a qualifying two-year degree (or ACAC's stated equivalent of 15 credit hours) plus at least one year of documented environmental allergen investigation experience. The second is no degree, but at least two years of consulting experience in environmental allergen investigations and a high-school diploma or GED. Qualifying education includes microbiology, engineering, science, architecture, industrial hygiene, or a related science.

Whichever route you take, ACAC expects applicants to have experience designing and conducting investigations. You submit the online application, four project sheets, and required email verifications, and you add transcripts if you are claiming education credit. Gathering verifiers and writing up four project sheets is usually the slowest part, so begin here, not with exam booking.

Step 2: Application review and approval

Once submitted, your application is reviewed. The exam cannot be treated as an independent event you can book in isolation; it sits inside the overall certification workflow. Because turnaround times are not published in the sources we reviewed, ask ACAC about current processing expectations when you apply instead of assuming a fixed number of days.

Step 3: Schedule your sitting

After approval, you coordinate delivery through Kryterion, choosing either a test center or secure online video proctoring. Scores are immediate, with email confirmation. Build in buffer time for booking, since popular test-center slots in your area may not be available the week you want them.

The 90-Day vs. Six-Month Deadline Conflict

The single most important scheduling detail is also the murkiest. ACAC's candidate handbook describes a 90-day rule for completing the process. The online application page, however, describes a six-month completion allowance that includes taking the exam. These two statements conflict, and the reviewed sources do not reconcile them.

The safe approach is to plan around the shorter 90-day figure until ACAC confirms otherwise in writing. If you finish early, nothing is lost. If you assume six months and the handbook rule applies, you could risk a lapsed application. Save any confirmation email you receive, since it becomes your reference if the two pages still disagree later.

Tying your study plan to the shorter window also keeps you honest. If you have not begun serious preparation, our CEAI study guide for passing on your first attempt can help you decide how much runway you realistically need before you submit.

Test Center vs. Secure Online Proctoring

Kryterion offers two delivery modes for this exam: a physical test center and secure online delivery with video proctoring. Both deliver the same closed-book, computer-based exam. The choice comes down to logistics and comfort.

Test center considerations

A test center offers a controlled room and managed equipment, which many candidates prefer if their home internet or workspace is unreliable. Note one documented inconsistency: the handbook says to arrive 30 minutes early, while the general examination page says 15 minutes. Follow the instructions on your actual appointment confirmation, and if in doubt, plan for the earlier arrival time.

Secure online proctoring considerations

Online delivery saves travel and can widen your choice of dates, but it requires a compliant space, a working camera, and a stable connection. Because the exam is closed-book, expect strict rules about your desk and surroundings. Run any system check Kryterion offers well before test day, not on the morning of the exam.

Exam Format and Fees at a Glance

Knowing what you are scheduling for helps you set a realistic date. The CEAI exam is 100 computer-delivered, closed-book multiple-choice questions, each with at least four answer options, and you have 3 hours. The passing score is 75%, set using the Modified Angoff Method. For a deeper look at how that threshold works, see our guide to the CEAI passing score.

A word of caution on cost: ACAC's general accredited-certification schedule lists USD 500 initially (USD 400 certification plus USD 100 examination) and USD 400 per two-year renewal. These are published category rates, not a separately verified CEAI-specific quotation, because the credential-specific application page did not render during our review. Confirm your exact total with ACAC before paying. Our CEAI certification cost breakdown walks through how these components fit together.

Matching Your Study Calendar to the Six Domains

Since your exam date is flexible, the smartest use of that flexibility is a domain-by-domain plan. ACAC publishes six official content headings but, in the sources reviewed, does not publish percentage weights, so do not assume any domain is worth more than another. Instead, sequence them logically, from foundation to application. This is the one place where a study schedule belongs in this article, and it is tied directly to the exam content.

This sequencing works because the later domains build on earlier ones: you cannot evaluate or remediate allergens (Domain 5) until you understand the allergen types and the buildings that harbor them (Domains 2 and 3). For a full explanation of each area, read our complete guide to the six CEAI exam domains. If your timeline is tight under the 90-day assumption, you can compress this plan, but keep the order.

Pacing the Seven Assigned Publications

ACAC's study packet lists seven assigned publications, and it recommends reading the complete texts rather than relying only on highlighted review pages. Note that publication years in the list (ranging from 2003 to 2018) are reference dates, not exam-release dates, so do not read them as signals of when content changes.

1. APHL, Environmental Laboratories and Indoor Air Testing: A Primer (2015)
2. CDC, Healthy Housing Reference Manual, chapter 5 (2006)
3. EPA, Exposure Factors Handbook, chapter 19 (updated 2018)
4. Estelle Levetin, Methods for Aeroallergen Sampling, Current Allergy and Asthma Reports 4:376-383 (2004)
5. HHS, Airborne Allergens: Something in the Air (2003)
6. HUD, Healthy Homes Issues: Asthma (2012)
7. HUD, Vacuum Dust Sample Collection Protocol for Allergens (2008)

Mapping these to domains helps you pace. The HHS and HUD asthma materials support your early work on the allergic response and allergen types. The CDC housing chapter supports built-environment principles. The Levetin article, the APHL primer, and the HUD vacuum dust protocol feed directly into investigation procedures and equipment. The EPA exposure chapter supports evaluation reasoning. Because the full texts are recommended, start reading early and budget more time than a highlight-only approach would suggest.

After You Test: Scores, Retakes, and the Two-Year Clock

Because scores are immediate and confirmed by email, you will know your result the day you test. A passing exam does not by itself make you certified: experience verification, the examination, and unanimous board approval are separate requirements, so factor in time after the exam before you can use the credential.

If you do not pass, ACAC lists a USD 100 retake fee. Check the current retake policy and any waiting period with ACAC, as the sources we reviewed do not detail restrictions. Given the application deadline ambiguity, ask whether a retake falls inside or outside your original completion window.

Planning for recertification now

Certification is valid for two years, and the renewal schedule lists USD 400 per two-year term. Current recertification procedures require 40 RCs per term: 10 for continued field activity plus 30 hours of professional development, with records retained for possible audit. ACAC's own materials are not fully consistent, though: the handbook describes 40 education and development hours, and the program overview mentions 20 professional-development hours per year. Confirm the current rule before you start logging hours.

The practical takeaway for scheduling: your exam date effectively starts a two-year clock, so build a simple habit of logging professional development from the start. If you are weighing whether the investment pays off, our analysis of whether the CEAI certification is worth it covers the longer-term picture.

Reading the Historical Statistics Carefully

ACAC's accredited certification activity summary as of December 31, 2025 reports a CEAI examination pass ratio of 50%, two applicants in 2025, and one current certification at that date. Treat this with caution. With only two applicants, a 50% figure reflects a tiny sample, applicant totals can include licensing-only candidates, and it is not a verified first-attempt or long-run pass rate, nor a prediction for 2026. For more context, see our discussion of the CEAI pass rate and what the data shows.

The small numbers also tell you something practical: this is a niche credential, so you should not expect crowded test calendars or large candidate cohorts. It also means study communities are small, and you will likely rely more on the assigned publications and structured practice than on peer forums.

Candidates ready to test their knowledge before booking can use the CEAI practice test site to check readiness against the six domains, and the full practice question bank offers timed sessions that mirror the 100-question, 3-hour format.
