What Is A CSRT, Exactly?
CSRT stands for Certified Concrete Surface Repair Technician, a credential issued at the Grade 1 level by the International Concrete Repair Institute (ICRI). It's designed to verify that a field technician can correctly diagnose deterioration in reinforced concrete and carry out repair work that meets accepted quality standards. If you've landed here searching "what is a CSRT," the short answer is: it's a hands-on, performance-verified certification for people who repair concrete surfaces for a living - not a desk-based credential, and not to be confused with other professional acronyms that happen to share the same three letters.
Because the name is shared by a few unrelated certifications in other industries, it's worth being precise: this article, and everything on CSRT Certification, refers only to the ICRI-administered Concrete Surface Repair Technician credential. If you want a plain-language breakdown of the acronym itself, see CSRT Meaning and What Does CSRT Stand For?
Who Administers the CSRT Credential
ICRI administers the CSRT program entirely through its online Learning Center, with the practical skills portion assessed via ICRI performance evaluation. There isn't a separate testing-center network to worry about - the knowledge-based components run through ICRI's digital platform, while the hands-on components are verified through video submission or live demonstration of ASTM performance tasks.
This matters for planning purposes: you're not scheduling a seat at a third-party test center the way you might for some other trade credentials. Instead, you're managing a multi-part course inside one learning portal, tracking deadlines against an 18-month overall completion window. For a full walkthrough of eligibility expectations before you enroll, check CSRT Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Exam Structure: Knowledge Test, Modules, and Performance Demos
The CSRT credential isn't earned with a single exam. It's built from several required components, and ICRI requires that every one of them be passed - there's no averaging across sections. The structure breaks down as follows:
- Initial knowledge exam: 65 questions, administered in one sitting, with a 3-hour time limit.
- Five module exams: each tied to one of the five official training modules covering the body of knowledge.
- Four ASTM performance demonstrations: practical, hands-on tasks verified via video submission or live evaluation.
The exact item format of the initial knowledge exam (straight multiple choice vs. scenario-based items) isn't something we can confirm with certainty, so treat any claim of a specific format as unverified until ICRI's own course materials confirm it. What is clear is that the knowledge exam is taken independently, in one sitting, separate from the module exams and the ASTM demonstrations. Candidates researching how demanding this combination is should read How Hard Is the CSRT Exam? Complete Difficulty Guide 2026 for a deeper look at what makes the multi-part structure challenging.
Key Takeaway
Passing the knowledge exam alone does not make you a CSRT. You must also clear five module exams and four ASTM performance demonstrations before certification is awarded.
The Five CSRT Training Domains
Officially, ICRI organizes the CSRT body of knowledge into five training modules. These are not weighted examination "domains" with published percentages - no verified breakdown exists showing one module carries more exam weight than another - but they do represent the subject areas a technician must master across the module exams and practical demonstrations.
Domain 1: What Is Reinforced Concrete? / Deterioration of Reinforced Concrete
Covers the composition and behavior of reinforced concrete and the mechanisms that cause it to deteriorate over time.
- Recognizing corrosion-driven deterioration patterns
- Understanding the role of reinforcement in structural behavior
Domain 2: Quality Requirements
Focuses on the quality benchmarks a repair must meet to be considered acceptable and durable.
- Standards governing acceptable repair outcomes
- Documentation expectations for quality assurance
Domain 3: Repair Methods and Materials
The technical core of the credential - matching the right repair method and material to the deterioration encountered.
- Selecting repair materials appropriate to exposure conditions
- Understanding method limitations and compatibility issues
Domain 4: Pre-placement Inspection
Everything that must be verified and prepared before repair material goes into place.
- Surface preparation checks
- Substrate condition evaluation prior to placement
Domain 5: Post-placement Inspection
Verifying that completed repair work meets required standards after placement and curing.
- Evaluating finished repair quality
- Identifying post-placement defects

What the CSRT Certification Package Actually Costs
Pricing for the CSRT program is structured around a bundled certification package rather than separate exam fees. The full certification package - which includes education plus the required video submission component - is priced at $599, and ICRI does not display a separate member/non-member split for that package.
There are also education-only pricing tiers, but it's important to understand these do not, by themselves, purchase the full certification:
| Option | Price | Includes Full Certification? |
|---|---|---|
| Certification Package | $599 | Yes - education + video submission |
| Education Only (Member) | $349 | No |
| Education Only (Student Member) | $149 | No |
| Education Only (Non-Member) | $495 | No |
In other words, the education-only tiers get you the coursework but not the credential itself - you still need to complete and pass the required exams and performance demonstrations separately.

Keeping Your CSRT Current: Renewal Rules
Once earned, the CSRT credential is valid for 5 years. Renewal isn't a rubber-stamp process - it requires passing a separate exam, distinct from the original knowledge test: 72 multiple-choice questions, a 3-hour time limit, and a 90% minimum passing score. That's a notably high bar compared to many renewal processes, and candidates should not assume renewal will be easier than initial certification.
The renewal window runs from 6 months before expiry to 9 months after it. Miss that window entirely, and the path back requires completing full certification again - including the performance demonstration components, not just the knowledge-based pieces. There is no CEU-based substitute identified for this renewal exam, and completing education hours (PDHs) alone does not satisfy the renewal requirement.
Key Takeaway
Renewal requires a 90% score on a separate 72-question exam - treat it as seriously as initial certification, not as a formality.
Who Hires a Certified Concrete Surface Repair Technician
Employers who value the CSRT credential tend to be organizations directly involved in structural concrete repair, restoration contracting, and infrastructure maintenance - anywhere reinforced concrete deteriorates and needs skilled, standards-based repair rather than cosmetic patching. Because the certification requires verified hands-on performance against ASTM methods, it signals to employers that a technician can be trusted on repair scopes that involve real structural consequences if done incorrectly.

Scheduling Your Prep Around the Five Domains
Because the CSRT program bundles a knowledge exam, five module exams, and four ASTM performance demonstrations inside an 18-month completion window, a simple study calendar helps more than generic exam tips. Rather than cramming everything at once, map your preparation to the module structure itself.
Foundations
- Study Domain 1 (reinforced concrete composition and deterioration)
- Review basic terminology before moving to applied topics
Standards and Methods
- Work through Domain 2 (Quality Requirements) and Domain 3 (Repair Methods and Materials)
- Cross-reference repair material choices against quality benchmarks
Inspection Practice
- Focus on Domain 4 (Pre-placement Inspection) and Domain 5 (Post-placement Inspection)
- Practice identifying defects in both pre- and post-placement scenarios
Exam and Demonstration Readiness
- Take timed practice sessions mirroring the 65-question, 3-hour knowledge exam format
- Rehearse ASTM performance demonstration tasks before video submission or live evaluation
Spacing review sessions this way keeps each module fresh heading into its corresponding module exam, rather than trying to hold all five bodies of knowledge in your head simultaneously.
