CCSI Passing Score 2026: Exactly What You Need to Pass

What "Passing" Actually Means for the CCSI

If you are searching for a single magic number, here it is: 70%. That is the minimum score required on each component of the ACI Concrete Construction Special Inspector (CCSI) examination. But the number alone hides most of what matters. The credential is not scored as one blended exam, and a strong result on one part cannot rescue a weak result on the other.

The governing document is the issuer's certification policy for the credential, ACI CPP 630.1-15 (revised March 21, 2014, effective January 1, 2015). It, together with the current program page, defines an assessment made of two separate written components. Understanding that structure is the first step in building a realistic study plan, and it is where many candidates misjudge the effort required. For a broader look at difficulty, see our guide on how hard the CCSI exam is.

Two Components, Two Separate 70% Thresholds

The assessment consists of a written-inspection component and a plans-reading component. Each is graded independently against the 70% threshold.

Question counts are approximate, so you should not build your preparation around an exact number of wrong answers you can afford. Because of that, this article deliberately does not convert 70% into a fixed count of missed questions. Treat the percentage as the binding fact and the counts as rough guidance from the issuer.

Notice the asymmetry. The plans-reading component is far shorter, but it carries equal weight in the pass decision: fail it and you have not passed the credential, no matter how well you did on the 80-question portion. With only about 20 questions, each item has an outsized effect on that component's percentage, which is why plans reading deserves dedicated drill time rather than leftover hours.

The One-Year Window Between Components

Candidates are not required to sit both components on the same day. The policy requires that both be passed within one year of each other. In practice this gives you flexibility to pass one component, then retake or complete the other, but it also creates a clock.

• Passing one component starts a one-year window for the other.
• If the window lapses before you pass the second component, you should confirm with your Sponsoring Group how the first result is treated rather than assuming it carries forward.
• Scheduling matters: local Sponsoring Groups, not a single national testing center, set when exams are offered. See our overview of CCSI exam dates and scheduling for how to plan around local offerings.

Open Book Changes How You Prepare, Not Whether You Prepare

Both components allow approved listed technical references. That sounds like it lowers the bar, but it shifts the challenge from memorization to navigation. With roughly 80 questions in three hours, you have a little over two minutes per written question on average. That is not enough time to read a code chapter from scratch for every item.

Effective open-book preparation for this credential means:

• Knowing which document answers which kind of question (tolerances, curing, cold weather, formwork, building-code inspection provisions).
• Tabbing and annotating your approved references so you can locate provisions quickly.
• Recognizing the terminology each document uses, so a question phrased one way points you to the right section.
• Answering immediately recognizable questions first and reserving look-up time for items that need it.

Our CCSI study guide goes deeper on building a reference-navigation routine, and you can test your look-up speed with questions on the main practice test site. Remember that independently authored practice questions are supplementary preparation only; they are not actual issuer questions and cannot measure field competence.

Where the Written Inspection Points Come From

The public Job-Task Analysis (JTA) for this credential organizes the written-inspection reference subjects under sixteen headings, with a seventeenth for plans reading. Important caveat: these seventeen headings are a serialization of the published reference list, not an official weighted blueprint. ACI does not publish percentages for them, so no domain can honestly be called "highest weighted." Our full guide to all 17 content areas walks through each one.

The reference subjects include:

The separate public training curriculum (five modules covering inspection and the inspector, reports, statistical quality assurance, materials testing, concrete fundamentals, batching and mixing, preconcreting inspection, placing operations, curing and protection, slabs, architectural concrete, precast and prestressed concrete, grout and mortar, and records) is supplementary. It does not establish exhaustive examination coverage and is not a substitute blueprint.

Plans-Reading: Earning 70% Across Drawings

The plans-reading component is Domain 17 in this article's serialization. The JTA retains a detailed set of tasks that tell you what the questions are likely to ask you to extract from a drawing set. Based on those published task statements, preparation should cover:

• Drawing identification: titles, numbers, revisions, and approval dates.
• Reinforcing steel: size, grade, location, spacing, and splicing.
• Tolerances: placement, spacing, and cover.
• Bar details: hook, bend, tie, stirrup, and supplemental-reinforcement schedules.
• Geometry: concrete form shapes and sizes, section details, and general requirements.
• Cross-referencing: information spread across multiple drawings, stations, grids, and detail references.
• Preparation and joints: subgrade and form-surface preparation, joints, and blockouts.
• Mix requirements: specified strength, slump, admixtures, exposure, and durability.
• Embedded items: post-tensioning steel, dowels, and other embeds.

Because you cannot rely on generic drawing practice, work exercises where the answer requires moving between plan, section, and schedule. The practice test site offers independently authored drawing-style exercises, which help build the habit but do not replace field experience.

Reference Edition Traps That Cost Points

Open-book exams reward the candidate who is holding the right book. The live program lists pinned references, including CT-16, ACI 117-10(15), ACI 301-16, ACI 302.1R-15, ACI 318-14, ACI 347R-14, and IBC 2015, among others. Several published labels conflict across sources, and the honest approach is to know the conflicts rather than hide them:

• The live program refers to a CRSI "Manual of Standard Inspection," while the JTA and the reviewed reference-package description say "Manual of Standard Practice."
• The JTA lists ACI SP-2, Manual of Concrete Inspection, while the program lists MNL-2 and the reviewed reference-package record lists MNL-2(19).
• ACI 301 is titled "Specifications for Structural Concrete" in the JTA and package description, but "Specifications for Concrete Construction" in the program listing.
• ACI 308R curing titles and reapproval suffixes differ across sources.

The practical rule: confirm the authorized references with your Sponsoring Group before purchasing anything, and never substitute a newer code edition for the one the exam uses. A provision that changed in a later edition can lead you to a wrong answer even though you "know" the code. The ACI CP-21 reference package is the issuer's package for this credential, but its paid contents were not retrieved for this article, so verify what it contains and its current price directly. Our CCSI cost breakdown separates book costs from exam costs.

Passing Score Confusion: What This Is Not

Searchers comparing inspector credentials often assume one scoring rule applies everywhere. It does not. The ICC offers its own special inspector exams, such as reinforced concrete, with separate rules, and the ACI Associate level is a different offering. Do not carry a threshold, question count, or time limit from one program onto another. For the CCSI, the facts that count are the 70% minimum on each of the two components, the roughly 80-question and roughly 20-question formats, and the one-year window.

Likewise, the on-demand preparation course ACI offers has module quizzes that require 80%. That is a course requirement, not the certification's passing score, and course completion time or PDH credit is not exam duration or a substitute for the assessment. The course is described in our overview of CCSI training options.

Finally, the course marketing and the generic JTA introduction mention performance as well as written examinations. The selected program and policy specify written inspection plus plans reading. Do not budget time for a third CCSI practical exam. The separate Field Testing Technician prerequisite has its own assessment requirements, discussed next.

Passing the Exams Is Not the Same as Being Certified

A passing score is necessary but not sufficient. Full certification requires:

1. Field Testing Technician Grade I: 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 passed. Its practical assessment is separate and is not a CCSI component.
2. Acceptable experience: verified by your employer, establishing decision authority, compliance and field evaluation, reporting and inspection proficiency, and the required concrete-testing experience.

The education and experience alternatives range from a qualifying ABET-accredited bachelor's degree plus six months of experience, through other engineering degrees plus one year, two years of college or technical study (at least 60 credits) plus two years, a high-school equivalent plus three years, or five years of satisfactory experience. Degree acceptability and experience remain subject to ACI policy. Read the details in our CCSI requirements guide.

Certification is valid for five years after all requirements are satisfied. Recertification uses current criteria, including the Field I condition and both examinations; experience is not reevaluated for renewal at the same level. So the passing score is something you may need to earn again, which is another reason to build durable understanding rather than cram. The CCSI certification overview covers the lifecycle.

What You Pay Before You Ever See a Score

There is no single national standalone exam fee. Local Sponsoring Groups set examination prices, and many bundle them with review sessions and guides. For example, ACI Intermountain's October 2026 Salt Lake County offering lists USD 1,350 for members and USD 1,450 for nonmembers, covering guides, three review days, and both exams, with review on October 5-7 and the examination on October 8. That is a dated local bundle, not a national fee, and availability may have changed.

Budget for the Grade I prerequisite separately, since it carries its own assessments. Whether the investment pays off is a personal question; see our analyses of whether the certification is worth it and the salary picture, which should not be read as a measured certification premium.

A Domain-Sequenced Plan Aimed at 70%

Rather than a generic schedule, sequence your study around how the references interrelate. This is one example, not an issuer-endorsed plan:

Adjust the length to your experience; a seasoned field inspector may compress the early weeks. A concise recap of must-know facts is in our CCSI cheat sheet. For context on how others fare, see what the data shows in our CCSI pass rate article, and note that no pass rate is claimed here.
