- CCSI means Concrete Construction Special Inspector, an ACI credential with a written-inspection exam and a separate plans-reading exam.
- Both open-book components need at least 70%, and both must be passed within one year of each other.
- Full certification requires current ACI Concrete Field Testing Technician Grade I status plus employer-verified experience.
- Seventeen domains is a serialization count of reference headings, not an official weighted blueprint, so never assume one topic outweighs another.
What You Are Actually Studying For
Before building a study plan, be precise about the credential. CCSI here means the Concrete Construction Special Inspector certification from the American Concrete Institute (ACI). It is the full inspector credential, not the Associate level, and it should not be confused with any other credential that happens to share the acronym. If you want the background on naming and scope, our explainers on what CCSI is and what CCSI stands for cover it in detail.
The certification is governed by ACI's policy document, Certification Policies for Concrete Construction Special Inspector (ACI CPP 630.1-15). Exams are administered by ACI-approved examiners and local Sponsoring Groups, with grading by ACI. That local layer matters: your Sponsoring Group controls scheduling, pricing, and which reference editions are authorized in the exam room.
The honest framing for exam prep is this: the exam tests whether you can find, interpret, and apply information from a defined set of technical references and project drawings. It rewards navigation skill and field-informed judgment far more than rote recall. Because the exams are open book, the candidates who struggle are usually the ones who never learned where things live in their references.
The Two Exam Components and the One-Year Window
The CCSI is assessed through two separate written components. They are not combined into a single score.
| Component | Format | Time | Passing Requirement |
|---|---|---|---|
| Written inspection exam | Approximately 80 multiple-choice questions, open book | Three hours | At least 70% |
| Plans-reading exam | Approximately 20 multiple-choice questions, open book | One hour | At least 70% |
Question counts are approximate, and because the components are scored independently, you cannot offset a weak plans-reading result with a strong written result. Both must be passed, and the second pass must occur within one year of the first. Miss that window and you will need to repeat the component that lapsed. For a deeper look at the cutoff mechanics, see our CCSI passing score guide.
Two clarifications prevent common confusion. First, some course marketing and generic job-task-analysis introductions mention "performance" examinations. The exact program and policy specify written inspection plus plans reading, so do not plan for a third CCSI practical. Second, the Field Testing Technician Grade I credential you need as a prerequisite does have its own practical assessment, but that belongs to Grade I, not to the CCSI. Keep those two things separate in your head and your calendar. If you are weighing how demanding all this is, read how hard the CCSI exam is.
Eligibility Comes Before Study
Many candidates open the reference books before confirming they qualify. Do it in the other order. Full certification requires:
- Current ACI Concrete Field Testing Technician Grade I certification, or previous Grade I certification plus passing its current written examination within one year of the first Inspector examination you pass.
- Acceptable employer-verified experience, which can be met through one of several education and experience alternatives.
Education and Experience Alternatives
ACI policy recognizes several paths. Degree acceptability and experience remain subject to ACI policy review.
- An ABET-accredited bachelor's in Civil Engineering, Civil Engineering Technology, Engineering Technology, Construction Engineering, or Construction Engineering Technology, with qualifying concrete coursework, plus six months of satisfactory experience
- Another engineering bachelor's degree plus one year of experience
- At least two years of college or technical study totaling at least 60 credits, plus two years of experience
- High-school equivalent plus three years of experience
- Five years of satisfactory experience
Employer verification is not a rubber stamp. It must establish decision authority, compliance and field evaluation, reporting and inspection proficiency, and the required concrete-testing experience. Associate status does not replace any of these full-credential requirements. Our CCSI requirements guide walks through qualifying in more detail.
Building Your Open-Book Reference Library
Open book does not mean easy. It means the exam assumes you can locate and apply published provisions quickly. The live certification program pins a specific reference set, including:
- CT-16 (ACI Concrete Terminology)
- ACI 117-10(15) tolerances
- ACI PRC-213-14 (lightweight-aggregate concrete)
- ACI 301-16
- ACI 302.1R-15 (floors and slabs)
- ACI 304R-00(09) and 304.2R-96 (placing and pumping)
- ACI 305R-10 (hot weather) and 306R-10 (cold weather)
- ACI 308R-01 (curing) and 309R-05 (consolidation)
- ACI 318-14, chapters 1-2, 17, 19-20, and 25-26
- ACI 347R-14 (formwork)
- IBC 2015, chapters 17 and 19
- MNL-2 (the ACI inspection manual), without a stated edition in the program listing
- The listed CRSI reference
ACI also sells a bundled reference package, CP-21, which an earlier reviewed record describes with slightly different suffixes (304.2R-96(08), 308R-01(08), MNL-2(19), and the CRSI Manual of Standard Practice, 2009). Treat those as provenance, not as a guarantee of what is currently in the package. Do not substitute newer code editions for the ones your Sponsoring Group authorizes; the exam is written against the listed versions. Tab and annotate your own copies in advance, where the rules permit, so you can navigate under time pressure.
Mapping the 17 Domains to Real Inspection Work
ACI's public job-task analysis organizes exam-linked reference subjects into sixteen headings, and the plans-reading component supplies a seventeenth. This is a serialization count, not an official weighted seventeen-domain blueprint, so no domain should be treated as "the biggest." The public headings are also not a promise of exhaustive coverage of the paid standards. For the full list, see our CCSI exam domains guide. Here is how to think about them by function.
Foundations: Terminology, Tolerances, and Specifications
Domain 1 (ACI Concrete Terminology), Domain 2 (ACI 117, Specification for Tolerances for Concrete Construction and Materials), and Domain 4 (ACI 301, Specifications for Structural Concrete) form the vocabulary and acceptance-criteria backbone.
- Learn how ACI 117 frames tolerances so you can find them quickly rather than memorize values
- Understand how a project specification invokes ACI 301 and what that means for your inspection duties
- Use terminology to resolve ambiguous question wording
Production and Placement
Domain 6 (ACI 304R, measuring, mixing, transporting, and placing), Domain 7 (ACI 304.2R, placing by pumping), Domain 11 (ACI 309R, consolidation), and Domain 5 (ACI 302.1R, floor and slab construction) cover what happens when concrete leaves the truck.
- Connect each guide to a field scenario: a pump line setup, a vibrator spacing problem, a slab finishing decision
- Know how these guides describe good practice versus what a specification mandates
Environmental Control: Hot Weather, Cold Weather, and Curing
Domain 8 (ACI 305R, hot weather), Domain 9 (ACI 306R, cold weather), and Domain 10 (ACI 308R, curing) are closely related. Treat them as one connected study block so you can contrast how temperature extremes change protection and curing decisions.
Structural and Code Framework
Domain 12 (ACI 318, Building Code Requirements for Structural Concrete), Domain 13 (ACI 347R, formwork), Domain 15 (ICC 2015 International Building Code), and Domain 3 (ACI 213R, structural lightweight-aggregate concrete) set the regulatory and structural context.
- For ACI 318, the program pins chapters 1-2, 17, 19-20, and 25-26, so focus your reading there rather than the whole code
- For the IBC, the pinned chapters are 17 and 19, which is where special inspection requirements live
Inspection Practice and Reinforcement Standards
Domain 14 (ACI SP-2, Manual of Concrete Inspection) is the inspector's own handbook and occupies the widest span of the public job-task analysis. Domain 16 (CRSI Manual of Standard Practice) governs reinforcing steel conventions. Together they anchor what an inspector actually does and documents.
ACI's separate on-demand training curriculum organizes material differently, into five modules: inspection and the inspector, reports and statistical quality assurance, materials testing and storage; concrete fundamentals, proportioning, and batching and mixing; preconcreting inspection through postconstruction; slabs, pavements, bridge decks, architectural concrete and special methods; and special concrete, precast and prestressed work, grout, mortar, stucco, and records. That curriculum is supplementary and unweighted. It is not a substitute blueprint and does not add domains. If you are choosing training, our CCSI training overview compares options.
Mastering the Plans-Reading Component
Domain 17 is a separate one-hour exam of approximately 20 questions, and it trips up candidates who are strong in the field but have not trained their eyes on a drawing set. The public job-task analysis points to a specific set of skills worth practicing deliberately:
- Identifying drawing titles, numbers, revisions, and approval dates, so you know which sheet governs
- Reading reinforcing size, grade, location, spacing, and splicing
- Checking placement, spacing, and cover tolerances
- Interpreting hook, bend, tie, stirrup, and supplemental-reinforcement schedules
- Understanding concrete-form shapes and sizes, section details, and general requirements
- Gathering information that is scattered across multiple drawings
- Following stations, grids, and detail references
- Recognizing subgrade and form-surface preparation, joints, and blockouts
- Pulling specified strength, slump, admixtures, exposure, and durability requirements
- Locating post-tensioning steel, dowels, and other embedded items
Because the component is timed at roughly three minutes per question, you need to flip between sheets fluently. Practice with real or realistic drawing sets, not just text summaries. Independently authored drawing exercises, including those on our practice test site, help build the habit but cannot replace field experience or ACI's own assessment.
Reference-Version Conflicts You Should Know About
Published sources do not always agree on titles and editions, and a careful candidate should know where the friction is rather than assume a typo.
| Item | Source Variation |
|---|---|
| CRSI reference | The live program says "Manual of Standard Inspection," while the job-task analysis and a reviewed reference-package description say "Manual of Standard Practice" |
| ACI inspection manual | The job-task analysis calls it ACI SP-2, Manual of Concrete Inspection; the program lists MNL-2; a reviewed package record lists MNL-2(19) |
| ACI 301 title | Job-task analysis and package description say "Specifications for Structural Concrete"; the program says "Specifications for Concrete Construction" |
| ACI 308R | Curing titles and reapproval suffixes differ across sources |
These discrepancies are unresolved in the public record, so we do not silently standardize them. The practical response is to carry the question to your Sponsoring Group: ask exactly which titles and editions are authorized and which will be in the exam room. Study the substance of each guide rather than the label.
Separating Exam Costs From Book and Course Costs
One of the most common budgeting errors is assuming there is a single national exam fee. There is not. Local Sponsoring Groups set examination prices, and training and reference materials are separate line items.
| Cost Item | What Is Publicly Listed | Caveat |
|---|---|---|
| Local review plus both exams (example) | ACI Intermountain's October 2026 Salt Lake County offering lists USD 1,350 member / USD 1,450 nonmember, including guides, three review days, and both exams | A dated local bundle, not a national standalone exam fee, and availability is not assured |
| CP-21 reference package | A reviewed quote of USD 305 member / USD 575 nonmember | Current price was not reconfirmed due to a store retrieval error |
| ACI on-demand course | USD 290 member / USD 390 nonmember, 180-day access, 10 PDH / 1 CEU | Module quizzes require 80%, but the certification requires 70%; course time is not exam duration and does not substitute for recertification |
For a fuller breakdown, see our CCSI certification cost guide, and for the career-return side of the equation, whether the certification is worth it. Salary context lives in the CCSI salary guide, which treats earnings qualitatively rather than implying a guaranteed certification premium.
A Domain-Sequenced Study Schedule
Generic study advice matters less here than sequencing the content in a sensible order. The schedule below is a suggestion, not a guarantee of results; adjust the pacing to your experience and your exam date. For timing logistics, check the CCSI exam dates guide and your Sponsoring Group's calendar.
Eligibility and Foundations
- Confirm Grade I status and experience documentation
- Obtain authorized references and tab them
- Study terminology, ACI 117, and ACI 301 together
Production and Placement
- ACI 304R, 304.2R, 309R, and 302.1R as one placement block
- Tie each guide to a real field scenario
Environment and Protection
- ACI 305R, 306R, and 308R studied side by side
- Contrast hot, cold, and curing decisions
Code, Formwork, and Inspection Manual
- Pinned chapters of ACI 318 and IBC chapters 17 and 19
- ACI 347R, SP-2/MNL-2, and the CRSI reference
Plans Reading and Timed Practice
- Daily drawing-set tracing exercises
- Timed written-inspection sets using your annotated references
Reserve plans reading for its own block rather than tacking it on at the end, since it is scored separately and carries its own 70% requirement. A one-page cheat sheet can help consolidate must-know facts, though in an open-book setting your annotated references are the real asset.
After You Pass: Validity and Recertification
The certification is valid for five years after all requirements are satisfied. Recertification applies current criteria, including the Field I condition and both examinations. Experience is not reevaluated for renewal at the same level. Plan your renewal timeline early, because the Field I credential has to be current as well. For a broader view of the credential itself, see our overview of CCSI certification, and for where the credential is put to work, CCSI jobs.
Key Takeaway
Treat the CCSI as two separate open-book exams with one year to clear both. Confirm Grade I and experience first, lock down authorized reference editions with your Sponsoring Group, and give plans reading its own dedicated practice block.
One more caution: independently authored practice material, including questions and drawing exercises on our CCSI practice site, is supplementary knowledge preparation. It is not actual ACI exam content, not an official mock exam, and cannot certify field competence or replace experience, Grade I, or ACI's assessment. For data on outcomes, our CCSI pass rate article explains what is and is not publicly known.
Frequently Asked Questions
Yes. Both the written-inspection component and the plans-reading component are open book with approved listed technical references. Confirm exactly which editions are authorized with your Sponsoring Group before exam day.
Each component requires at least 70%. The written-inspection exam (approximately 80 questions, three hours) and the plans-reading exam (approximately 20 questions, one hour) are scored separately, and both must be passed within one year of each other.
Full certification requires current ACI Concrete Field Testing Technician Grade I certification, or previous Grade I plus passing its current written exam within one year of your first Inspector exam pass. Its practical assessment is separate and is not a CCSI component.
There is no single national fee; local Sponsoring Groups set prices. One dated example from ACI Intermountain lists USD 1,350 member or USD 1,450 nonmember for a bundle with guides, review days, and both exams. Books and courses are separate costs.
Five years after all requirements are satisfied. Recertification uses current criteria, including the Field I condition and both examinations, and does not reevaluate experience at the same level.
