CSMT Exam Dates 2026: Testing Windows, Deadlines & Scheduling

TL;DR
  • CSMT sessions are scheduled events run by ICRI, not on-demand testing windows you book at a local center.
  • One example 2026 session ran November 4-5 at Structural Technologies in the Baltimore, MD area.
  • The written exam is one hour, plus a separate one-hour performance appointment; the 3-4-hour education session is not exam time.
  • Failed written exams or performance methods must be retaken within one year, or the full course must be repeated.

How CSMT Scheduling Actually Works

Most people searching for exam dates expect a familiar model: pick a testing center, pick a Tuesday, and sit down at a computer. The Concrete Slab Moisture Testing Technician-Grade 1 credential does not work that way. It is issued by the International Concrete Repair Institute (ICRI), and the certification is delivered through scheduled certification sessions that combine classroom education, a demonstration and workshop, a written examination, and a hands-on performance evaluation.

That structure changes how you plan. Instead of choosing from a rolling calendar of open appointments, you look for a session that fits your travel, your employer's schedule, and your preparation timeline. Sessions are hosted at venues around the country, often at the facilities of industry companies. A published example for 2026 is the ICRI CSMT Program scheduled for November 4-5, 2026 at Structural Technologies in the Baltimore, MD area.

Why there is no single "testing window": Because the credential depends on a live, in-person judge watching you perform five field tests, the "exam date" is really the date of the session you register for. Always confirm the current session list directly on the ICRI program page rather than relying on a third-party calendar, since session locations and dates are added over time.

What a Certification Session Includes

A full-course registration bundles several components, and understanding them helps you read the schedule correctly. The published program covers an education session, a demonstration and workshop, the written examination, and the performance evaluation. Certification requires passing the ICRI-administered written examination and successfully performing all five tests before a qualified judge without coaching.

The five tests map directly to the five reference topics ICRI lists for preparation. These headings are issuer-listed examination-reference and preparation topics, including applicable annexes and appendices. They are not a percentage-weighted blueprint, and they are not an exhaustive one, so treat them as the core of what you will handle in the field rather than a score-by-section map. For a deeper breakdown of each area, see the complete guide to all five CSMT content areas.

The Five Reference Topics Behind the Session

Your session day is organized around these standards, which you will both study and physically perform.

  • ASTM F710 - Preparing Concrete Floors to Receive Resilient Flooring, including Section 5.2 pH Testing
  • ASTM F1869 - Measuring Moisture Vapor Emission Rate of Concrete Subfloor Using Anhydrous Calcium Chloride
  • ASTM F2170 - Determining Relative Humidity in Concrete Floor Slabs Using in situ Probes
  • ASTM F2659 - Preliminary Evaluation of Comparative Moisture Condition of Concrete, Gypsum Cement and Other Floor Slabs and Screeds Using a Non-Destructive Electronic Moisture Meter
  • ASTM F3191 - Field Determination of Substrate Water Absorption (Porosity) for Substrates to Receive Resilient Flooring

One practical note on editions: use the standard editions supplied to registered candidates. Older study lists that still include ASTM F2420 are legacy material and should not replace the editions in your participant packet.

Finding and Registering for a 2026 Session

The authoritative source is the ICRI Concrete Slab Moisture Testing (CSMT) Program page, which lists upcoming sessions and links to registration. Individual events, such as the November 4-5, 2026 session near Baltimore, also have their own event pages with fee and scheduling details that corroborate the main program page.

  1. Check the ICRI program page for the current list of sessions and their locations.
  2. Open the specific event page for the session you are considering and note the dates, venue, and fee tiers.
  3. Confirm your eligibility path (see the next section) before paying, so you know whether you need the demonstration and workshop for a prequalification waiver.
  4. Register under the correct membership category, since the fee differs for ICRI members, non-members, and verified student members.
  5. Watch for your participant packet after registration; it supplies the standard editions you will be tested on.
Registration tip: Because sessions are physical events with limited hands-on capacity, treat registration as something to do early rather than the week before. If you need approval from an employer for travel and the fee, build that into your timeline first.

Eligibility Checks Before You Book

Eligibility is a gating item that affects which session and which pathway you choose. ICRI's eligibility requires one of two routes: ICRI-approved previous hands-on testing experience, or a prequalification waiver obtained through participation in the Demonstration and Workshop. If you have documented field experience with the relevant tests, you may qualify on that basis. If you are newer to the work, the demonstration and workshop component is how you satisfy the prerequisite within the same trip.

For the full picture of who qualifies and how to document experience, read CSMT Requirements: Eligibility, Prerequisites & How to Qualify. Sorting this out before you pick a date prevents the most common scheduling mistake: registering for a session and then discovering a paperwork gap.

2026 Fees by Membership Category

The published 2026 full-course fees include the education session and the demonstration/workshop. They are tiered by membership status:

Category2026 Full-Course Fee (USD)
ICRI member$1,050
Non-member$1,350
Verified student member$510

The gap between member and non-member pricing is $300, which is worth weighing against the cost of ICRI membership itself if you plan to certify and recertify over time. For a complete cost picture that includes recertification, see the CSMT certification cost breakdown.

Key Takeaway

The online Education Course sold separately by ICRI does not lead to certification and cannot be credited toward the certification program. Do not buy it as a cheaper substitute for the full course; register for a certification session if certification is your goal.

Exam-Day Timing: Written vs. Performance

When you read a session schedule, separate the instructional time from the examination time. The published schedule allocates:

ComponentPublished TimeCounts as Exam Time?
Education session3-4 hoursNo
Written examination1 hourYes
Performance appointmentSeparate, assigned 1-hour slotYes

The performance appointment is individually assigned, so you may not control exactly when in the session you perform. Plan your travel to allow for the full session rather than assuming you can leave right after the written exam. The written examination also covers the education session content, so pay attention during instruction rather than treating it as optional background.

A written question count and a numeric passing threshold were not verified for this article, so do not trust any site that states a specific number without citing ICRI. For what is and is not known, see CSMT Passing Score: Exactly What You Need to Pass, and for realistic expectations on difficulty, How Hard Is the CSMT Exam?

Retake Windows and Hard Deadlines

The most date-sensitive part of the CSMT process is not the initial session; it is what happens if something does not go your way. The retake rules carry real deadlines:

  • Failed initial written exam: you must retake the written examination in full.
  • Failed performance methods: only the failed methods are repeated, not all five.
  • One-year limit: retakes must be completed within one year, or the full certification course must be repeated.

That one-year clock is the deadline that matters most for candidates who do not pass everything on the first try. If a second session near you is months away, factor that into your plan immediately after the first attempt rather than letting weeks slip by. Missing the window means paying for and sitting through the full course again.

Practical Retake Planning

Because only failed performance methods are repeated, targeted practice pays off.

  • Note which of the five tests gave you trouble while it is fresh.
  • Identify the next session that fits inside your one-year window.
  • Repeat your hands-on practice on the specific method, such as probe placement for ASTM F2170 or calcium chloride kit handling for ASTM F1869.
  • Re-review the written material in full, since a failed written exam must be retaken entirely.

Recertification Timing

Certification lasts five years, so your second major date is the one that arrives half a decade after you pass. The structure is tiered:

StageRequirementMember FeeNon-Member Fee
First recertificationWritten exam only$495$595
Second and later recertificationsFull certification course$695$895

A failed first-recertification written exam has its own, shorter deadline: a six-month re-examination window before the full course is required. That is a tighter clock than the one-year limit for the initial certification, so schedule your first recertification early enough that a failed attempt still leaves room to retake it.

A note on the renewal wording: ICRI's page contains a later-renewal heading referencing "10+ years after first recertification," which appears to conflict with its explicit five-year cycle. The page does not establish a ten-year validity period, so plan around the five-year cycle and confirm timing with ICRI as your expiration approaches.

Working Backward From Your Session Date

Once you have a session date, the sensible approach is to build your preparation around the five reference topics and the hands-on performance. Because you will be judged performing every test without coaching, the physical procedures deserve as much attention as the written content. The timeline below is one way to sequence it across a six-week lead time, with the most procedure-heavy topics given the most room.

Weeks 6-5

Foundation: ASTM F710 and pH Testing

  • Study the role of ASTM F710 in preparing concrete floors for resilient flooring
  • Focus on Section 5.2 pH testing, retained exactly as ICRI lists it
  • Learn how pH results fit into a broader slab assessment
Weeks 4-3

Core Moisture Methods: F1869 and F2170

  • Work through moisture vapor emission rate testing with anhydrous calcium chloride
  • Study in situ relative humidity probe procedures
  • Memorize setup, conditioning, and reading requirements for each
Week 2

Screening and Porosity: F2659 and F3191

  • Understand what a non-destructive electronic moisture meter can and cannot tell you
  • Review field determination of substrate water absorption
Week 1

Integration

  • Rehearse all five procedures in sequence
  • Review any education-session topics, since the written exam covers them

The logic of this order is that F710 gives you the framework, the two quantitative moisture methods (F1869 and F2170) are the most procedure-intensive and benefit from the longest runway, and the screening and porosity tests round out the picture. For a fuller approach to preparation, see the CSMT Study Guide, and for a quick final review, the CSMT Cheat Sheet. You can also pressure-test your recall with the practice questions on the main practice test site.

Key Takeaway

Because the performance evaluation is unassisted, written knowledge alone will not carry you. Spend your final weeks rehearsing physical steps, and reserve your practice-question sessions on the CSMT practice tests for written reinforcement.

If you are still weighing whether to commit to a session at all, the ROI analysis and the earnings guide can help you decide whether the fee and travel are justified for your situation.

Frequently Asked Questions

Can I take the CSMT exam any day I choose?

No. The credential is delivered through scheduled ICRI certification sessions, not on-demand appointments. You register for a specific session, such as the one published for November 4-5, 2026 in the Baltimore, MD area, and take the written exam and performance evaluation as part of that event.

How long is the written exam compared to the whole session?

The published schedule allocates one hour to the written examination and a separate, assigned one-hour performance appointment. The 3-4-hour education session is instructional and is not examination time, though the written exam covers its content.

What happens if I fail part of the exam?

A failed initial written exam must be retaken in full, while failed performance methods alone are repeated. Either must be completed within one year, or you must repeat the full certification course.

How long does certification last, and when do I recertify?

Certification lasts five years. First recertification is written-exam-only, with a separate six-month re-examination deadline if you fail. Second and later recertifications require the full certification course.

Does the separately sold online Education Course count toward certification?

No. ICRI's online Education Course does not lead to certification and cannot be credited toward the certification program. To certify, you need to register for a full certification session.
