ATT2 Certification Cost 2026: Complete Pricing Breakdown

Understanding the ATT2 Fee Structure

Aggregate Testing Technician - Level 2 is an ACI (American Concrete Institute) credential, but ACI itself does not sell a single national exam seat the way some computer-based certification programs do. Instead, ACI-approved sponsoring groups and examiners - local chapters, ready-mix associations, and DOT-affiliated organizations - administer the written and performance examinations under ACI's certification policies (CPP 620.3-20). That means the "cost of ATT2" is really the cost of whichever local program you register through, plus any materials you buy separately.

This matters for budgeting because two candidates sitting the identical written exam and performance exam, covering the identical ten standards, can pay very different amounts depending on which sponsor organizes their session. Before you commit to a date, it's worth reading through the ATT2 requirements guide to confirm you already hold a current Aggregate Testing Technician - Level 1 credential, since that prerequisite is non-negotiable and typically not covered by exam-day fees.

What Local Sponsor Packages Actually Include

The two published 2026 examples illustrate how differently a "full ATT2 package" can be assembled. Some sponsors bundle the study guide, an in-person review session, the written exam, and the performance exam into one flat fee. Others charge only for exam administration and expect candidates to buy the CP-45 workbook and prepare independently.

Knowing which model your sponsor uses changes how you plan your own study time. If a review session is included, you can lean on it for clarifying tricky procedure steps in domains like flat and elongated particle testing. If it is not included, you'll want a self-directed plan - the kind laid out in our ATT2 study guide - built around the ten standards rather than around a classroom schedule.

2026 Price Comparison: Two Named Programs

Here is how the two published 2026 examples compare side by side. Both are legitimate ACI-approved sponsoring pathways for Aggregate Testing Technician - Level 2, but the fee structures differ meaningfully.

The gap between member and nonmember pricing is worth noting in both cases. If you're an employer sponsoring multiple technicians, or a technician planning to sit ATT2 more than once in a career, chapter or association membership can meaningfully offset the cost over time.

Prerequisite Costs: ATT1 and Study Materials

Because certification requires holding a current ACI Aggregate Testing Technician - Level 1 credential, factor in that prior investment when you calculate your total path to ATT2. If your ATT1 has lapsed, you may need to address that before a sponsor will let you register for Level 2 testing.

On the materials side, ACI's own preparation workbook - CP-45, seventh edition - is sold as a standalone item for $133 at the regular rate or $69 for ACI members. If your chosen local sponsor's package already includes the workbook (as ACI Intermountain's does), buying it separately would be a wasted expense. If your sponsor's package excludes it (as CRMCA's does), plan for that line item before exam day.

Written and Performance Exam Cost Mechanics

ATT2 candidates sit two distinct components, and understanding how they're structured helps explain why the fees are set the way they are:

• Written examination: Open-book using ACI-approved references, two hours long, approximately 100 multiple-choice questions, with eight to 12 questions drawn from each of the ten standards. A simple-function, nonprogrammable pocket calculator is permitted.
• Performance examination: Closed-book, requiring correct demonstration or permitted verbal description of prescribed procedure steps for the seven practical standard areas (AASHTO T 96/ASTM C131, AASHTO T 104/ASTM C88, and ASTM C535 are written-exam-only).

Passing requires at least 60% on every individual standard on the written exam and at least 70% overall, in addition to passing the separate performance component. Both components must be passed within one year of each other. If you fail one component, you retake that component in full - the component you already passed remains valid within the one-year window, so you are not paying to redo something you already cleared.

That retake rule has direct cost implications: a sponsor's fee typically covers one attempt at each component, so a failed attempt on either the written or performance exam may mean an additional fee for the retake session. This is one more reason candidates take the ATT2 exam difficulty seriously before their first sitting, and why understanding the exact ATT2 passing score requirements matters as much as understanding the fee schedule.

Hidden and Add-On Costs to Watch For

Beyond the headline registration fee, a few line items can catch candidates off guard:

• Card processing fees. CRMCA's published price sheet notes a 3.05% credit-card processing fee on top of the stated registration cost.
• Separately purchased workbooks. Some sponsors, including CRMCA's Denver program, do not bundle the CP-45 workbook into the registration fee.
• No included review session. Programs without an exam-day training or review component put more weight on independent preparation, which may mean investing more time (and possibly a practice-test resource) before test day rather than relying on a classroom refresher.
• Nonmember pricing. Both published examples charge substantially more for nonmembers, so checking chapter or association membership status before registering is worth the few minutes it takes.

Many candidates supplement whichever local package they choose with independent practice, particularly for the four multiple-choice-heavy domains that carry no hands-on performance component. Running through realistic scored questions on our ATT2 practice test platform is a low-cost way to stress-test your readiness before paying for an exam sitting.

Recertification Costs After Five Years

ATT2 certification lasts five years. Recertification is not a paperwork renewal - it requires passing both the written and performance examinations again, under the same standards structure and passing thresholds as the original certification. In practical terms, budget for recertification the same way you budgeted for your original credential: a local sponsor fee, possibly a refreshed copy of CP-45 if the edition has changed, and study time proportional to how much the ten standards have shifted since your last exam.

Because the Job-Task Analysis underlying the exam domains is periodically revised by ACI (the current version was approved September 30, 2024), it's worth checking the ATT2 exam domains guide before a recertification attempt to confirm nothing has changed in the standards mix since you last tested.

Budgeting Study Time Across the Ten Domains

Cost isn't only measured in dollars - study time is a cost too, and how you allocate it across the ten ATT2 domains affects how many attempts (and how many fees) you ultimately pay. The written exam draws eight to 12 questions from each of the ten standards, so no domain can be safely skipped, but three standards - AASHTO T 96/ASTM C131, AASHTO T 104/ASTM C88, and ASTM C535 - appear only on the written exam, while the remaining seven require hands-on performance readiness as well.

This kind of week-by-week allocation front-loads the three standards that only need written-exam mastery, then spends the bulk of remaining time on the seven standards where you'll need both conceptual and procedural fluency. For a deeper breakdown of what each standard actually tests, see the complete ATT2 exam domains guide, and for a quick pre-exam refresher, the ATT2 cheat sheet condenses the must-know figures from each standard onto a single page.

Frequently Asked Questions

A failed component must be retaken in full, which typically involves an additional fee, while a component you already passed remains usable within the one-year window and does not need to be repeated.
