- CSRT content is organized into five training modules, not weighted exam percentages - treat each as equally important.
- The initial knowledge exam is 65 questions over 3 hours; you also must pass five module exams and four ASTM performance demonstrations.
- All required components - knowledge exam, module exams, and performance demos - must be passed individually; there's no averaging.
- Certification runs through ICRI's Learning Center and costs $599 as a full package with education and video submission included.
How the CSRT Exam Is Structured
Before diving into the five content areas, it helps to understand what you're actually preparing for. The Certified Concrete Surface Repair Technician (CSRT) credential is administered by ICRI through its online Learning Center, and the path to full certification-awarded as Concrete Surface Repair Technician, Grade 1-involves more than a single multiple-choice test.
Candidates complete an initial knowledge exam (65 questions, 3 hours), five module exams tied to the training curriculum, and four ASTM-based performance demonstrations submitted via video or evaluated live. Every one of these components must be passed independently; there's no blending a strong knowledge-exam score with a weak performance demonstration. If you want a deeper breakdown of how these pieces fit together and what "passing" actually means component by component, see our CSRT Passing Score 2026 guide.
Domain 1: What Is Reinforced Concrete? / Deterioration of Reinforced Concrete
This module lays the technical foundation for everything else in the credential. Candidates need a working command of how reinforced concrete is designed to function, and-more importantly for a repair technician-how and why it fails over time.
Core Concepts in This Module
Expect to demonstrate understanding of the composite relationship between concrete and embedded steel reinforcement, along with the primary mechanisms that break that relationship down.
- Corrosion of embedded reinforcing steel and its drivers (chloride exposure, carbonation, moisture cycling)
- Common visual and structural indicators of deterioration: spalling, delamination, cracking, and rust staining
- How load paths and the concrete-to-steel bond are compromised as deterioration progresses
- Why early detection of deterioration matters to the eventual repair approach
Technicians who struggle here often underestimate how much the rest of the credential depends on this vocabulary. Pre-placement and post-placement inspection (Domains 4 and 5) both reference deterioration concepts introduced here, so skipping ahead tends to backfire.
Domain 2: Quality Requirements
This module shifts from diagnosing problems to defining what "acceptable" repair work actually looks like. It's less about memorizing a single number and more about understanding the standards-driven mindset that governs concrete repair quality control on a jobsite.
What Candidates Must Internalize
- How quality benchmarks are established and verified during a repair project
- Documentation habits that support traceability and accountability for each repair
- The relationship between specified materials, approved procedures, and acceptable outcomes
- Why consistent quality checks reduce callbacks and liability for a repair contractor
If you've read our difficulty breakdown of the CSRT exam, you'll know this module is frequently cited as deceptively conceptual-there isn't a single formula to memorize, so candidates need to reason through quality scenarios rather than recall a fixed answer.
Domain 3: Repair Methods and Materials
This is the largest practical body of knowledge in the curriculum and the module most directly tested through the ASTM performance demonstrations. Candidates are expected to connect a given deterioration type to an appropriate repair method and the materials suited to execute it correctly.
High-Value Study Areas
- Surface preparation techniques appropriate to different substrate conditions
- Bonding agents, patching materials, and overlay systems and when each is appropriate
- Curing requirements and how they differ across repair material types
- Matching repair method selection to the root cause identified in Domain 1
This is also the module most candidates revisit repeatedly during prep. Our CSRT Study Guide 2026 walks through a practical sequence for pairing material knowledge with hands-on practice so the two reinforce each other instead of being studied in isolation.
Domain 4: Pre-placement Inspection
Pre-placement inspection covers everything a technician should verify before any repair material goes into place. Getting this stage wrong undermines every material and technique decision made in Domain 3, which is exactly why ICRI treats it as its own dedicated module.
What This Module Tests
- Confirming substrate condition is suitable for the planned repair method
- Verifying surface preparation meets the requirements of the specified repair material
- Checking environmental conditions (temperature, moisture) that affect material performance
- Identifying when a repair should be delayed or escalated before placement proceeds
Candidates sometimes treat inspection modules as "soft" compared to hands-on repair skills, but pre-placement inspection errors are a common root cause of repair failure in the field-which is likely why ICRI builds it into the formal credential rather than leaving it to on-the-job learning.
Domain 5: Post-placement Inspection
The final module closes the loop: once repair material is in place, how do you confirm the work was done correctly and will hold up over time? This module tests judgment about finished work rather than judgment about preparation.
Core Skills Assessed
- Evaluating cure quality and surface finish against expected standards
- Identifying early warning signs that a repair may be failing (cracking, debonding, discoloration)
- Documenting completed work for quality and warranty purposes
- Understanding when post-placement conditions require corrective follow-up
Domains 4 and 5 are often studied together because they bookend the same repair event from opposite sides. If you're building a final review pass before exam day, our CSRT Cheat Sheet 2026 groups inspection-related concepts together for exactly this kind of last-mile review.
How These Modules Connect to Your Exam Components
It's worth being explicit about how the five training modules map onto the actual components you must pass. The initial knowledge exam draws broadly from all five areas, the five module exams map more directly one-to-one with these topics, and the four ASTM performance demonstrations concentrate heavily on applied skills from Domains 3, 4, and 5.
| Exam Component | Format | Primary Content Relationship |
|---|---|---|
| Initial Knowledge Exam | 65 questions, 3 hours | Draws across all five modules |
| Five Module Exams | Tied to curriculum modules | One exam per domain area listed above |
| Four ASTM Performance Demonstrations | Video or live evaluation | Concentrated in repair methods and inspection domains |
| Renewal Exam (within validity window) | 72 questions, 3 hours, 90% minimum | Separate assessment, not tied to original module exams |
Key Takeaway
Don't study for "the CSRT exam" as if it's one test. Budget separate preparation time for the knowledge exam, each module exam, and the hands-on performance demonstrations - they assess different things in different formats.
Who Actually Hires People With This Credential
CSRT-credentialed technicians typically work in concrete restoration and repair contracting, often on commercial, industrial, or infrastructure projects where structural concrete has experienced corrosion, spalling, or delamination. Employers value the credential because it signals the holder has been evaluated on both the diagnostic knowledge (why concrete fails) and the applied skill (how to fix it correctly) rather than one or the other alone.
If you're trying to decide whether this credential fits your career direction, our CSRT Jobs overview and CSRT Salary Guide 2026 dig into the kinds of roles and employers where this certification tends to matter most. For a broader cost-versus-benefit view before you commit to the $599 certification package, Is the CSRT Certification Worth It? walks through the considerations in more depth.
Scheduling Your Prep Around Five Modules
Because the credential is built from five distinct modules plus hands-on demonstrations, a single generic study calendar won't serve you well. Instead, sequence your preparation around the dependency structure of the content: foundational knowledge first, applied methods second, inspection judgment last.
Domain 1 Foundations
- Build fluency in deterioration mechanisms and terminology
- Connect corrosion/spalling concepts to later repair decisions
Domain 2 & Domain 3
- Study quality requirement concepts alongside repair materials
- Begin hands-on practice toward ASTM performance demonstrations
Domains 4 & 5
- Practice pre-placement and post-placement inspection scenarios together
- Review how inspection failures trace back to Domain 1 and 3 content
Integration & Mock Practice
- Take full-length practice questions covering all five areas
- Finalize performance demonstration logistics before the 18-month completion window closes
Remember that ICRI gives candidates an overall course completion window of 18 months to finish every required component, so pacing matters more than cramming. For a more detailed week-by-week breakdown with specific question-practice targets, see our full CSRT Study Guide 2026, and run timed practice sets on our practice test platform to simulate the 3-hour knowledge exam format.
Registration, Fees, and Renewal Mechanics
Understanding the content domains only matters if you also understand how the credential itself is structured financially and administratively. The full certification package is $599, which includes the education component and video submission for performance evaluation - there is no separate member/non-member pricing displayed for that package. Education-only options exist at lower price points ($349 member, $149 student member, $495 non-member), but purchasing education alone does not confer certification; you still need to pass the knowledge exam, module exams, and performance demonstrations.
Once earned, the credential is valid for 5 years. Renewal can be completed within a window from 6 months before expiry to 9 months after, using a separate 72-question, 3-hour multiple-choice exam with a 90% minimum passing score. There is no CEU-based renewal substitute, and completing education hours alone does not satisfy renewal. If you miss the renewal window entirely, you're required to go through full certification again, including the performance demonstrations. For the complete fee structure and what to budget for, see our CSRT Certification Cost 2026 breakdown, and for eligibility details before you register, check CSRT Requirements 2026.
