CSRT Certification

TL;DR
  • CSRT certification is administered by ICRI through its online Learning Center, awarding Concrete Surface Repair Technician-Grade 1.
  • The full certification package costs $599 and bundles education with a required video submission; education-only tiers do not grant certification alone.
  • Candidates must pass an initial 65-question, 3-hour knowledge exam, five module exams, and four ASTM performance demonstrations - all components are mandatory.
  • Credential validity is 5 years, with renewal priced at $449 via a separate 72-question, 3-hour exam requiring a 90% minimum score.

What the CSRT Certification Actually Is

The Certified Concrete Surface Repair Technician (CSRT) credential recognizes technicians who can evaluate, prepare, and restore deteriorated reinforced concrete surfaces according to industry-accepted methods. It is formally awarded as Concrete Surface Repair Technician-Grade 1, signaling a foundational, field-verified level of competency rather than an entry-level knowledge quiz. If you're still mapping out what this designation covers versus other similarly-named credentials in adjacent fields, our companion explainer on What Is CSRT Certification? walks through the basics in plain language, and CSRT Meaning clarifies the terminology candidates encounter on official materials.

Unlike purely multiple-choice credentials, CSRT blends a written knowledge exam with hands-on performance evaluation. That combination is the single most important thing to understand before you register, because study time has to be split between textbook-style preparation and physical skill rehearsal - a distinction we unpack further in the CSRT Study Guide 2026: How to Pass on Your First Attempt.

Why the Grade 1 Label Matters: The "Grade 1" designation tied to this certification signals that it sits at a defined competency tier within the concrete repair technician pathway. Treat it as a floor of demonstrated capability, not a ceiling - many technicians use it as the launching point for broader field responsibility.

Who Administers It and What It Costs

CSRT is administered by ICRI through its online Learning Center, with performance components evaluated directly by ICRI. There is no separate certifying board distinct from ICRI itself, and there is no publicly displayed member/non-member fee split for the full certification package - a detail that often trips up candidates comparing it to other trade certifications.

The full certification package runs $599, and it includes the required education content plus the mandatory video submission component. This is the package that actually results in certification. Separately, ICRI also lists education-only pricing: $349 for members, $149 for student members, and $495 for non-members. These education-only tiers are important to understand clearly - they do not, by themselves, confer certification. They cover instructional content only; the knowledge exam, module exams, and ASTM performance demonstrations still have to be completed and passed separately.

Key Takeaway

Before you pay anything, confirm whether you're purchasing the $599 full certification package or one of the education-only tiers ($349/$149/$495) - they are not interchangeable, and only the full package leads to the credential.

Exam Structure: Knowledge Test, Modules, and Performance Demos

CSRT certification is not a single exam - it's a multi-part sequence, and every required component must be passed before the credential is awarded. The structure breaks down as follows:

  • Initial knowledge exam: 65 questions, administered over a 3-hour window, taken alone in one sitting. The precise item-format specification (straight multiple-choice vs. scenario-based items) has not been independently verified, so candidates should prepare for either style.
  • Five module exams: Separate assessments tied to the five official training modules covering the full technician knowledge base.
  • Four ASTM performance demonstrations: Hands-on evaluations, submitted via video or completed live, that verify practical application of repair techniques against ASTM standards.

Whether open-book access, calculator use, or adaptive question delivery are permitted has not been confirmed in available documentation, so it's wise to prepare as though none of those conveniences will be available on exam day. Candidates get an 18-month window to complete the entire course sequence - knowledge exam, all five module exams, and all four performance demonstrations - so pacing matters as much as raw knowledge.

All-or-Nothing Component Rule: Passing the knowledge exam does not mean you're certified. Every module exam and every ASTM performance demonstration must also be passed individually. There's no averaging across components.

And if you want the specific numeric thresholds you need to clear on each component, CSRT Passing Score 2026: Exactly What You Need to Pass lays it out directly.

The Five CSRT Training Domains

CSRT preparation is organized around five official training modules. It's worth being precise here: these are instructional domains, not weighted examination categories - there is no confirmed percentage breakdown indicating that one domain counts more heavily than another on the knowledge exam. Treat all five as equally essential to master.

Domain 1: What Is Reinforced Concrete? / Deterioration of Reinforced Concrete

Covers the composition and behavior of reinforced concrete and the mechanisms - corrosion, carbonation, freeze-thaw cycling, chemical attack - that cause it to deteriorate over time.

  • Recognizing visual and structural signs of rebar corrosion and spalling

Domain 2: Quality Requirements

Focuses on the standards and specifications a repair job must satisfy to be considered acceptable, including documentation and compliance expectations.

  • Understanding how quality benchmarks tie into ASTM-referenced criteria

Domain 3: Repair Methods and Materials

The technical core of the certification - surface preparation techniques, patching materials, bonding agents, and application methods appropriate to different deterioration types.

  • Matching repair material selection to the specific deterioration diagnosed in Domain 1

Domain 4: Pre-placement Inspection

What must be verified and documented before any repair material goes down - substrate condition, surface profile, moisture, and preparation quality.

  • Checklist-style evaluation of readiness before placement

Domain 5: Post-placement Inspection

Evaluating the finished repair for curing, bonding integrity, surface finish, and overall conformance to the original quality requirements.

  • Identifying post-repair defects that indicate a failed application

Because these five areas map directly to the module exams and influence the ASTM performance demonstrations, candidates benefit from working through each domain in sequence rather than jumping around. Our CSRT Exam Domains 2026: Complete Guide to All 5 Content Areas expands each of these into a fuller study outline, and the CSRT Cheat Sheet 2026: One-Page Review of Must-Know Facts is a useful quick-reference once you've covered the material in depth.

Who Hires Certified Concrete Surface Repair Technicians

CSRT-credentialed technicians typically work in concrete restoration, structural repair contracting, and infrastructure maintenance settings where reinforced concrete surfaces - parking structures, bridges, industrial floors, and building facades - require ongoing inspection and remediation. Because the certification verifies both inspection judgment and hands-on repair execution, employers often view it as evidence a technician can be trusted on-site without constant supervision for Domain 3 through Domain 5 tasks.

If you're evaluating this certification as a career move, CSRT Jobs outlines the kinds of roles and employers where the credential tends to be recognized, and CSRT Salary Guide 2026: Complete Earnings Analysis covers compensation considerations without relying on unverified figures. For a broader look at what the letters actually represent in this specific field - distinct from other industries that reuse the same acronym - see What Does CSRT Stand For? and What Is A CSRT?.

Building a Preparation Timeline Around the Domains

Given the 18-month completion window and the all-or-nothing component rule, a structured timeline matters more here than in single-exam certifications. Rather than generic weekly study advice, anchor your schedule to the specific components you still need to pass.

Weeks 1-3

Domains 1 & 2 Foundations

  • Study reinforced concrete deterioration mechanisms and quality requirement standards
  • Begin reviewing ASTM reference documents cited in course materials
Weeks 4-7

Domain 3 Deep Dive

  • Work through repair methods and materials content module by module
  • Practice matching materials to deterioration scenarios from Domain 1
Weeks 8-10

Domains 4 & 5 Inspection Skills

  • Rehearse pre- and post-placement inspection checklists
  • Schedule or film the ASTM performance demonstrations
Weeks 11-12

Consolidation and Scheduling

  • Take practice assessments covering all five domains together
  • Confirm the 3-hour knowledge exam sitting and remaining module exam dates

This kind of domain-anchored pacing is more effective than generic spaced-repetition advice because it respects the structural reality of CSRT: five distinct module exams plus four performance demonstrations, all inside one completion window. For scheduling logistics specific to this certification, check CSRT Exam Dates 2026: Testing Windows, Deadlines & Scheduling, and run a few timed practice sessions on our practice test platform before committing to a real exam date.

Renewal: Keeping Your Grade 1 Credential Active

CSRT certification is valid for 5 years. Renewal is handled through a separate exam - 72 multiple-choice questions, 3 hours, requiring a 90% minimum passing score - and costs $449. The renewal window opens 6 months before expiration and stays open until 9 months after expiration, giving candidates a reasonable buffer either side of the actual expiry date.

If that window closes without a completed renewal, the pathway reverts to full recertification, including the performance demonstration components again - not just the written exam. There is no CEU-based substitute for renewal currently identified, and completing education-only PDH content does not satisfy the renewal requirement on its own.

PathwayCostFormat

Education Only (Non-Member)$495Instructional content only - no certification awarded
Renewal (within window)$44972-question, 3-hour exam, 90% minimum score

Frequently Asked Questions

Who administers the CSRT certification?

ICRI administers the Certified Concrete Surface Repair Technician credential through its online Learning Center, and ICRI also conducts the performance evaluation component directly.

Does buying the education-only package certify me as a CSRT?

No. The education-only tiers ($349 member, $149 student member, $495 non-member) cover instructional content only. Certification requires the full $599 package, which includes the video submission, plus passing the knowledge exam, five module exams, and four ASTM performance demonstrations.

How long do I have to complete all the CSRT requirements?

Candidates have an overall 18-month window to complete the full course sequence, including the knowledge exam, all module exams, and all performance demonstrations.

What happens if my CSRT certification expires before I renew?

The renewal window runs from 6 months before expiration to 9 months after. If you miss that window entirely, you must complete full recertification again, including the performance demonstration components - not just a renewal exam.

Are the five CSRT domains weighted differently on the exam?

The five areas - Reinforced Concrete & Deterioration, Quality Requirements, Repair Methods and Materials, Pre-placement Inspection, and Post-placement Inspection - are official training modules. There is no confirmed weighting showing any domain counts for a larger percentage than the others, so all five warrant equal preparation.
