- The initial knowledge exam is 65 questions in 3 hours; ICRI has not published a fixed numeric cut score for it.
- Renewal uses a separate 72-question, 3-hour exam that demands a 90% minimum score.
- Full certification runs $599 with education and video submission; education-only packages ($349/$149/$495) do not grant certification on their own.
What "Passing" Actually Means for CSRT Certification
When people search for the "CSRT passing score," most are picturing a single number - like a driving test cutoff - that determines pass or fail. The reality of the Certified Concrete Surface Repair Technician credential, administered by ICRI through its online Learning Center, is more layered. There isn't one gatekeeping score standing between you and the Concrete Surface Repair Technician-Grade 1 designation. Instead, candidates must clear every required component of the program: the initial knowledge exam, five module exams tied to the training curriculum, and four ASTM performance demonstrations that are evaluated in person or via video submission.
That matters because "passing score" questions usually assume a single exam event. If you're coming to this page expecting one magic percentage, you need to recalibrate: CSRT certification is an all-or-nothing bundle of assessments, and missing any one of them means you are not yet certified, regardless of how well you scored on the others. For a broader orientation to what the credential involves before you get into scoring mechanics, the CSRT Certification overview and the What Is CSRT Certification? explainer are good starting points.
The Initial Knowledge Exam: Format and Scoring
The initial knowledge exam consists of 65 questions administered in a 3-hour sitting. This is taken alone, as opposed to the performance demonstrations, which allow video or live evaluation options. ICRI has not published a verified breakdown of item format for this exam - whether it is purely multiple-choice, includes scenario-based items, or mixes question types is not something candidates can confirm from public materials, so it's worth treating the format as unconfirmed rather than assuming it mirrors other trade exams you may have taken.
What is also unverified publicly: whether the exam is open-book, whether a calculator is permitted, and whether the exam uses adaptive delivery. Rather than guessing, the safest approach is to prepare as though the exam is closed-book and timed strictly at 3 hours for 65 questions - a pace of roughly 2.75 minutes per question if you want a rough budgeting benchmark. For a fuller breakdown of how the overall exam experience tends to feel for candidates, see How Hard Is the CSRT Exam? Complete Difficulty Guide 2026.
Key Takeaway
Prepare for the 65-question, 3-hour knowledge exam as if it were closed-book and strictly timed. Don't assume open-book access or calculator use unless ICRI confirms it for your specific exam window.
Module Exams and ASTM Performance Demonstrations You Must Also Pass
Beyond the knowledge exam, candidates must pass five separate module exams and complete four ASTM performance demonstrations. This is where CSRT differs sharply from typical multiple-choice-only certifications: you are not just answering questions about repair methods, you are demonstrating that you can execute them according to ASTM standards, with ICRI performance evaluation confirming competency.
The five modules correspond to the training curriculum and knowledge domains candidates are expected to master:
Domain 1: What is Reinforced Concrete? / Deterioration of Reinforced Concrete
Covers the fundamentals of reinforced concrete construction and the mechanisms - corrosion, carbonation, freeze-thaw, chemical attack - that cause it to deteriorate over time.
- Understanding the relationship between rebar corrosion and concrete spalling
Domain 2: Quality Requirements
Focuses on the standards and specifications a repair must meet to be considered compliant and durable.
- Recognizing acceptable tolerances and documentation expectations
Domain 3: Repair Methods and Materials
The technical core of the credential - selecting and applying the correct repair material and method for a given deterioration type.
- Matching material properties to substrate condition and exposure
Domain 4: Pre-placement Inspection
What must be verified before repair material goes into place - surface preparation, substrate soundness, and environmental conditions.
- Identifying disqualifying surface conditions before placement
Domain 5: Post-placement Inspection
Evaluating the finished repair for soundness, bond, and compliance after curing.
- Spotting signs of delamination, cracking, or improper cure
Because each module exam must be passed independently, there is no mechanism to "average out" a weak domain with a strong one the way some single-exam certifications allow. For a deeper walkthrough of each content area and how they interconnect, see the CSRT Exam Domains 2026: Complete Guide to All 5 Content Areas.
Why No Single Domain Carries the Most Weight
A common question candidates ask is which domain carries the heaviest weighting on the exam, assuming they should pour extra study hours into whichever topic counts for the most points. For CSRT, that framing doesn't quite apply. The five areas listed above are official training modules, not weighted examination domains with disclosed percentages. There is no published figure indicating that, say, Repair Methods and Materials counts for more of your final outcome than Pre-placement Inspection.
Practically, this means you should prepare to pass each module exam on its own merits rather than triaging your study time based on assumed point values. Treat all five as equally mandatory gates rather than ranking them by weight you cannot verify.
The Renewal Exam's 90% Threshold
If there is one concrete, specific "passing score" figure attached to this credential, it belongs to renewal, not initial certification. CSRT is valid for 5 years. Renewal is handled through a window that opens 6 months before expiration and stays open until 9 months after expiration, using a separate 72-question, multiple-choice exam administered in 3 hours. That renewal exam requires a 90% minimum score to pass.
This is notably stricter than anything disclosed about the initial knowledge exam, and it's a detail many candidates overlook when they're focused purely on first-time certification. If you let your renewal window lapse past the 9-month post-expiration mark, the consequence is significant: you no longer qualify for the streamlined renewal exam and instead must complete full certification again, including the performance demonstration components.
There is no CEU-based substitute for this renewal exam. Completing education hours (PDHs) does not satisfy the renewal requirement on its own - you still have to sit for and pass the 72-question exam at 90%.
Key Takeaway
Mark your calendar 6 months before your 5-year expiration date. Missing the 9-month post-expiration grace period means repeating full certification - performance demonstrations included.
Registration, Fees, and What You're Actually Paying For
Understanding the scoring structure is easier once you understand what you're paying for at each stage. Full CSRT certification - including education and video submission for the performance components - runs $599. This is the package that actually results in the Concrete Surface Repair Technician-Grade 1 award.
Separately, ICRI lists education-only pricing: $349 for members, $149 for student members, and $495 for non-members. These education-only tiers are easy to confuse with the full certification fee, but they do not, by themselves, grant certification. They cover coursework access, not the credentialing package that includes exam and performance evaluation.
Renewal, as noted above, costs $449 and is tied to the separate 72-question exam rather than the original certification package. For a full line-by-line cost comparison, including how these figures stack up against the time investment, read CSRT Certification Cost 2026: Complete Pricing Breakdown.
| Item | Cost | What It Includes |
|---|---|---|
| Full Certification Package | $599 | Education, video submission, knowledge exam, module exams, performance evaluation |
| Education Only (Member) | $349 | Coursework access only - no certification |
| Education Only (Student Member) | $149 | Coursework access only - no certification |
| Education Only (Non-Member) | $495 | Coursework access only - no certification |
| Renewal Exam | $449 | 72-question, 3-hour exam, 90% minimum to pass |
Whatever path you take through the fee structure, you have an 18-month overall course completion window to finish every required component of initial certification. That clock is separate from the exam's own 3-hour time limit - it's the broader deadline for getting your knowledge exam, module exams, and performance demonstrations all completed and passed.
Building a Study Timetable Around the Five Modules
Because CSRT requires passing five discrete module exams plus a knowledge exam plus performance demonstrations, a generic cramming schedule won't serve you well. Instead, sequence your preparation around the structure of the credential itself rather than a one-size-fits-all study calendar.
Foundations
- Work through Domain 1 (reinforced concrete and deterioration mechanisms) and Domain 2 (quality requirements) since later modules build on this vocabulary
Technical Core
- Focus heavily on Domain 3 (repair methods and materials) - the densest and most applied module
Inspection Skills
- Pair Domain 4 (pre-placement inspection) and Domain 5 (post-placement inspection) together since they mirror each other across the repair timeline
Performance Readiness
- Rehearse the four ASTM performance demonstrations and sit practice knowledge-exam questions under a strict 3-hour simulated limit
Spacing your review this way - foundations first, technical application in the middle, inspection skills before the performance demonstrations - lines up with how the modules build on each other rather than forcing unrelated topics into the same week. For a more detailed week-by-week framework and first-attempt strategy, see the CSRT Study Guide 2026: How to Pass on Your First Attempt, and keep a condensed reference like the CSRT Cheat Sheet 2026: One-Page Review of Must-Know Facts on hand during final review days.
Running timed practice questions on our practice test platform before exam day is one of the most direct ways to rehearse the 3-hour, 65-question pacing you'll face, since there's no substitute for simulating the actual time pressure.
Initial vs. Renewal Exam at a Glance
| Feature | Initial Knowledge Exam | Renewal Exam |
|---|---|---|
| Question Count | 65 | 72 |
| Time Limit | 3 hours | 3 hours |
| Format | Unverified item format | Multiple-choice |
| Minimum Score | Not publicly disclosed | 90% |
| Additional Requirements | 5 module exams + 4 ASTM performance demonstrations | None (unless window missed, then full recertification applies) |
| Validity After Passing | 5 years | Resets 5-year validity |
Notice how much tighter the renewal exam's scoring bar is compared to what's publicly known about the initial path. That gap alone is a good reason not to treat renewal as an afterthought once you're already certified - it's arguably the harder numeric target of the two.

Frequently Asked Questions
ICRI has not published a confirmed numeric cut score for the 65-question, 3-hour initial knowledge exam. What is confirmed is that candidates must also pass five module exams and four ASTM performance demonstrations - the knowledge exam score alone does not determine certification.
By the numbers, yes in one sense: the renewal exam requires a 90% minimum score, a figure that is explicitly disclosed. No equivalent minimum percentage is published for the initial knowledge exam, making the renewal threshold the more concrete benchmark to study against.
Every required component - the knowledge exam, all five module exams, and all four ASTM performance demonstrations - must be passed individually. There is no averaging mechanism described in the certification structure.
No. Education-only pricing ($349 member, $149 student member, $495 non-member) covers coursework access but does not include the exam and performance evaluation components required for the Concrete Surface Repair Technician-Grade 1 award. Full certification requires the $599 package.
The certification process is bound by an 18-month overall completion window for all required components. Specific consequences of exceeding that window for partially completed components aren't fully detailed in public materials, so candidates should confirm directly with ICRI's Learning Center before assuming any credit carries forward.
