CRER Exam Dates 2026: Testing Windows, Deadlines & Scheduling

TL;DR
  • CRER is the Council-certified Residential Environmental Remediator credential from ACAC, with exams delivered through Kryterion rather than on a fixed national...
  • The exam is 50 multiple-choice questions in two hours, closed book, with a 70% passing criterion.
  • The current application page allows six months to complete the process; older handbook language mentions 90 days.
  • Online proctoring requires a private location, approved webcam and a continuous 2 Mbps upload/download connection.

How CRER Scheduling Actually Works

Searching for "CRER exam dates 2026" usually turns up a mix of unrelated credentials and recycled calendars. This article covers only the Council-certified Residential Environmental Remediator, administered by the American Council for Accredited Certification (ACAC). Certification decisions are made by ACAC's CRER Certification Board, and the testing provider is Kryterion, Inc.

The most useful thing to understand up front is that CRER scheduling is candidate-driven. ACAC's published materials describe an application, an examination and a board review, not a handful of annual sitting dates that you must catch or miss. Instead of circling a date on a calendar, you control the sequence: submit the application, complete email verification, schedule the exam through the delivery option you choose, sit the test, and wait for the certification board's review.

If you are still deciding whether this credential is right for you, start with What Is CRER Certification? and the eligibility rundown in CRER Requirements 2026: Eligibility, Prerequisites & How to Qualify, then come back to plan your timing.

Why There Is No Published 2026 Test Calendar

We found no fixed 2026 testing-window table in the issuer materials we reviewed, and we will not invent one. What the sources do establish is how exams are delivered:

  • Testing-center delivery through the Kryterion network.
  • Online, video-proctored delivery from your own location.
  • Instructor-proctored vocational examinations through ACAC arrangements, which the current application form also offers.

Because delivery is built around these channels, "dates" in practice means the appointment slots available to you at the time you schedule. Availability depends on the delivery method and location you pick, so check the live scheduling screen rather than relying on any third-party list of dates.

Beware of recycled date tables: Several other well-known credentials use the same four-letter acronym and publish fixed testing windows, deadlines and fees. Those details do not apply to the ACAC Council-certified Residential Environmental Remediator. If a page shows seasonal windows or dollar figures that differ from the ones in this article, confirm the certifying body before trusting it.

The Application-to-Exam Timeline

Think of your 2026 plan as a sequence of gates rather than a calendar. Here is the order of operations drawn from the issuer's application materials:

  1. Confirm eligibility. The CRER handbook requires current employment in indoor environmental remediation. The current form's affidavit words this as indoor environmental consulting and adds attestations on legal work status, regulatory compliance and ethics.
  2. Submit the application with an electronic signature.
  3. Verify your email. This step is required, so watch for the verification message and complete it promptly.
  4. Schedule and sit the examination through testing center, online proctoring or vocational proctoring.
  5. Board review. Certification requires unanimous review by the CRER Certification Board after you pass.

The current application page expressly exempts CRER from project sheets, even though generic handbook process wording mentions them. CRER eligibility also does not carry the two-year experience route associated with CIER, and no degree is a prerequisite. For how those paths differ, see the comparison discussion in our requirements guide.

Reading Conflicting Application Sources

One reason scheduling questions get confusing is that ACAC's own documents do not perfectly agree. The table below shows where the handbook's generic language and the current application page diverge, and which one governs for CRER.

TopicGeneric handbook languageCurrent application page
Completion window90 daysSix months
VerificationNotarized applicationOnline/email verification
Employment proofEmployer affidavitAffidavit within the form; CRER employment route applies
Project sheetsDescribed in generic processCRER expressly exempt
Education proofDiploma/transcript wordingNo degree prerequisite for CRER

The handbook's generic checklist items do not override the exact CRER employment route or the explicit project-sheet exemption. Practically, that means you should work from the live application, and if anything in your packet seems to demand a notary, transcript or project sheet that the form does not, ask ACAC directly before spending money or time.

Why the six-month window matters: If the current page's six months governs your application, you have room to schedule the exam after a realistic study period. If the older 90-day wording were applied strictly, you would need to compress your plan. Confirm which window applies to you when you apply, and write down the date in your own calendar.

Testing Center, Online, or Vocational Proctoring

Your choice of delivery method affects which "dates" you can realistically book. All three share the same exam content: 50 multiple-choice questions with at least four answer choices each, two hours, closed book, with randomized question and answer order and immediate results.

Online video-proctored

Online candidates supply their own computer, an approved webcam, a private location and a continuous 2 Mbps upload/download connection. Test your setup well before your appointment, and choose a room where nobody will walk in during the two hours. A dropped connection is a scheduling problem you can prevent.

Testing center

A Kryterion testing center removes the home-setup variables. It suits candidates who share living space, have unreliable internet, or simply focus better in a controlled room. Factor in travel time when you pick a slot.

Instructor-proctored vocational examination

The current form also offers instructor-proctored vocational examinations through ACAC arrangements. This option may fit candidates who are completing training and want to sit the exam in that setting. One caution: optional course hours are not exam timing. A prep or vocational course is optional for CRER, and its length has no bearing on the two-hour exam clock or on any application deadline. See CRER Training for how preparation options fit in.

Fees, Retakes and Timing Decisions

Money and timing are linked, because a retake means another appointment and another charge. Here is how the issuer's charges break down:

ItemAmountNotes
Initial fee, US/CanadaUSD 400USD 100 examination plus USD 300 vocational certification for the first two-year term
Current application quote, outside US/CanadaUSD 425As quoted on the current official application
RetakeUSD 100Per additional examination attempt
Renewal (every two years)USD 300Plus 40 renewal credits (RCs)

Optional preparation purchases such as courses or flashcards are separate from issuer charges, and they are not required. For the full breakdown, read CRER Certification Cost 2026: Complete Pricing Breakdown.

Key Takeaway

Because a retake is USD 100 rather than the full initial fee, the cost of sitting too early is real but bounded. Still, the cleanest plan is to book your exam only after a full practice-test pass at or above the 70% criterion, so you are not paying to find out you needed another month.

Planning Backwards From Your Exam Date

Since you choose your own exam date, the best use of this article is a backward plan. The ACAC handbook organizes its required skills into five groups, and those make natural study blocks. The issuer publishes no percentage weights, so treat the order below as a sensible sequence, not an official blueprint. For deeper domain coverage, see CRER Exam Domains 2026: Complete Guide to All 5 Content Areas.

Week 1

Domain 1: Asbestos

  • Read the asbestos provisions in 40 CFR 763, 40 CFR 61 Subpart M and 29 CFR 1926.1101
  • Focus on engineering controls, removal procedures and worker protection
Week 2

Domain 2: Lead

  • Study 40 CFR 745 and 29 CFR 1926.62
  • Connect containment, cleaning and clearance logic to worker exposure rules
Week 3

Domain 3: Hazardous materials

  • Work through 29 CFR 1910.120 and the mercury references
  • Note that ACAC's lists name two different mercury guidebooks and sections; learn both as written
Week 4

Domain 4: Microbial contaminants and allergens

  • Study the NYC fungi-remediation guidance (2008) named in the handbook
  • Review containment, cleaning and removal logic for moisture-related contamination
Week 5

Domain 5: Chemicals, plus respirators

  • Review chemical remediation, including the EPA methamphetamine laboratory cleanup guidelines the study guide names
  • Read the NIOSH Respirator Selection Logic (2004), which cuts across every domain
Week 6

Practice and gaps

  • Take timed 50-question sets under a two-hour limit
  • Revisit the domains where you miss questions

This is the only generic-style schedule in the article, and it is deliberately tied to CRER content: the order moves from the heavily regulated, document-driven topics to the more procedural ones, then ends with timed practice. Adjust the number of weeks to your own background. A working remediation technician may compress the early weeks; a newcomer may stretch them. For a fuller method, see CRER Study Guide 2026: How to Pass on Your First Attempt.

One warning about the reference list

The handbook cautions that its selected study pages are examples and assumes comprehensive knowledge of its references. Do not plan your schedule around reading only the highlighted pages. Budget time to read the underlying regulations and guidance, because that is what the exam assumes you know. Two links in the legacy reference list could not be retrieved, so lean on the handbook's own titles and section assignments when you search for current copies.

What Happens on Exam Day

Once your appointment arrives, the format is straightforward. You will face 50 multiple-choice questions with a two-hour limit, no outside materials, randomized question and answer order, and results shown immediately after you finish. The passing criterion is 70%, set by the certification board using the modified Angoff method. If you want the exact scoring details, see CRER Passing Score 2026: Exactly What You Need to Pass.

Exam-day checklist for online candidates

Do these the day before, not the hour before.

  • Confirm your approved webcam works and is positioned correctly
  • Run a connection check for continuous 2 Mbps upload and download
  • Clear your desk and arrange a private room
  • Have the identification your proctoring process requires ready
  • Close other applications on your computer

An immediate result is useful but not the whole story. Passing the examination is one step; certification also depends on the board's unanimous review. Hold off on using the designation until ACAC confirms your certification.

A note on difficulty and pass statistics

You may see pass-rate figures while planning. ACAC's 2025 exam pass ratio shows 0% from 0 passes in 2 examinations. That cohort is far too small to say anything about typical difficulty, and the report includes retakes and state-licensing-only examinations. Do not read it as a sign that the CRER is nearly impossible to pass. We cover the denominator and context in CRER Pass Rate 2026: What the Data Shows and How Hard Is the CRER Exam? Complete Difficulty Guide 2026.

After You Pass: Validity and Renewal Clock

Your certification is valid for two years, so the date you pass starts a renewal clock worth tracking from day one. Renewal costs USD 300 and 40 RCs. Under current procedures, 10 of those come from continued field activity, and 30 must be professional-development hours. Keep documentation for audit.

Also remember that certification is awarded to individuals, and that passing an examination for state licensing alone does not authorize the CRER designation or replace jurisdiction-specific licensing requirements. If your work requires a state license, check your jurisdiction's official source separately. To weigh whether the investment makes sense for your career, see Is the CRER Certification Worth It?
