Why There's No Single National ATT2 Test Date
If you're searching for a master 2026 calendar of "ATT2 exam dates" published by one national testing body, you won't find it - and that's by design, not an oversight. Aggregate Testing Technician - Level 2 (ATT2) examinations are administered through ACI-approved sponsoring groups and examiners, meaning local chapters, ready-mix associations, and testing agencies each schedule and run their own sessions throughout the year. There is no centralized enrollment portal with fixed quarterly windows the way some other certification programs operate.
This decentralized model means your actual "exam date" depends entirely on which sponsoring group you register with. Some chapters run sessions a handful of times per year; others tie testing to specific training events. Before you build a prep schedule, your first task is identifying which sponsoring group serves your region and confirming their 2026 dates directly - the details below give you two real, published examples to understand how this typically works.
2026 Sponsoring Group Examples
Two published 2026 examples illustrate how sponsoring groups structure their sessions and pricing. These are local packages, not a uniform national fee - a distinction that matters when you're budgeting and comparing options.
| Sponsoring Group | 2026 Fee | What's Included |
|---|---|---|
| ACI Intermountain Chapter (Utah) | $500 members / $600 nonmembers | Study guide, review session, written exam, performance exam |
| CRMCA at CDOT Headquarters (Denver, CO) | $598 members / $928 nonmembers | Full written and performance exam; workbooks purchased separately; no exam-day training/review; 3.05% credit-card processing fee applies |
Notice the structural difference: the Intermountain Chapter bundles a study guide and review session into its price, while CRMCA's Colorado package is exam-only, with workbooks bought separately and no built-in review. That difference should directly influence how you plan your ATT2 study guide preparation timeline - if your sponsoring group doesn't include a review session, you're responsible for covering all ten domains on your own before test day.
Key Takeaway
Before comparing prices across chapters, check what's actually bundled. A slightly higher fee that includes a review session and study materials may cost less in total than a cheaper exam-only package plus separately purchased workbooks.
Registration, Fees & Deadline Mechanics
Because sponsoring groups run their own sessions, registration deadlines vary by organization - but a few mechanics apply broadly across ATT2 administrations:
- Prerequisite verification comes first. You must hold a current ACI Aggregate Testing Technician - Level 1 credential before a sponsoring group will register you for ATT2.
- Materials cost varies by package. The standalone CP-45 seventh-edition workbook runs $133 regular or $69 for ACI members if your sponsoring group doesn't bundle it in.
- Payment processing fees can apply. Some sponsoring groups, like CRMCA, add a credit-card processing fee (3.05% in their 2026 sheet) on top of the base registration cost.
- Member vs. nonmember pricing is common. Both published 2026 examples charge a lower rate for members of the hosting organization.
For a full breakdown of what you're likely to spend once workbooks, membership status, and processing fees are factored in, see the ATT2 certification cost breakdown. Registration deadlines themselves are typically set a few weeks ahead of the session date by each sponsoring group, so contact your chapter early rather than assuming rolling admission.
What Test Day Actually Looks Like
Regardless of which sponsoring group hosts your session, the exam format itself is standardized by ACI. Scheduling your prep time around test day means understanding exactly what happens once you sit down:
- The written examination is open-book, using only ACI-approved references, runs two hours, and contains approximately 100 multiple-choice questions.
- Each of the ten standards receives eight to 12 questions on the written exam - no single domain dominates the question count.
- The performance examination is closed-book and requires you to correctly demonstrate - or, where permitted, verbally describe - prescribed procedure steps for hands-on testing standards.
- A simple-function, nonprogrammable pocket calculator is allowed; anything with programmable functions is not.
Passing requires at least 60% on every individual standard plus at least 70% overall on the written exam, in addition to successfully completing the performance exam. If you're unsure what those thresholds mean in practice, the ATT2 passing score breakdown walks through the math domain by domain.
The One-Year Rule for Passing Both Components
One scheduling detail catches candidates off guard: both the written and performance examinations must be passed within one year of each other. If you pass the written exam in March but don't schedule and pass the performance exam until 14 months later, that written pass no longer counts - you'd need to retake it in full.
The rule works both directions and it's forgiving within the window: a passed component remains usable for the full one-year period, so if you pass performance first and need extra time to schedule the written exam, you have up to a year to do so. But a failed component must be retaken in full - there's no partial credit or retesting only the missed questions within a component.
This matters directly for how you schedule your 2026 sessions. If your sponsoring group only offers performance exams quarterly but written exams monthly, plan your written attempt with enough buffer that a potential retake still fits inside the one-year clock alongside your performance exam date.
The Ten Standards You're Scheduling Around
Your prep calendar should be built around the ten standards ACI's Job-Task Analysis (approved September 30, 2024) identifies as ATT2 content areas. Three of these are written-exam-only, which changes how much performance-exam rehearsal time they require:
Domain 1 - AASHTO T 19/ASTM C29/C29M: Bulk Density and Voids in Aggregate
Candidates must know both bulk density calculation methods and voids determination - a practical standard tested in both exam components.
- Rodding, jigging, and shoveling procedures for filling the measure
Domain 2 - AASHTO T 96/ASTM C131: L.A. Abrasion, Small-Size Coarse Aggregate
Written-exam-only standard - no hands-on demonstration required, but grading requirements and abrasion charge selection still appear as multiple-choice questions.
Domain 3 - AASHTO T 104/ASTM C88: Soundness by Sodium or Magnesium Sulfate
Also written-exam-only. Focus study time on solution preparation, cycle counts, and loss calculations rather than physical demonstration.
Domains 4-7, 9-10 - The Seven Practical Standards
Clay lumps and friable particles (T 112/C142), lightweight pieces (T 113/C123), sand equivalent (T 176/D2419), uncompacted void content of fine aggregate (T 304/C1252), flat and elongated particles (D4791), and fractured particles (D5821) all require you to demonstrate or verbally walk through procedure steps on the performance exam.
- Prioritize these seven for hands-on rehearsal time before your scheduled performance date
Domain 8 - ASTM C535: L.A. Abrasion, Large-Size Coarse Aggregate
Written-exam-only, paired conceptually with Domain 2 but using different grading and charge specifications for larger aggregate sizes.
For a deeper walkthrough of each standard's specific procedure requirements and common question traps, see the full ATT2 exam domains guide. Knowing which three domains are written-only lets you allocate performance-exam rehearsal time to the seven that actually require it.
Building a Study Timeline Before Your Test Date
Once you have a confirmed sponsoring-group date, work backward. A generic weekly planner isn't useful here - your schedule needs to match the written-exam-only standards against the seven practical ones so you're not rehearsing procedures you'll never demonstrate.
Written-Only Standards
- Master T 96/C131, T 104/C88, and C535 - these appear only as multiple-choice questions, so focus on grading tables and calculations
Practical Standard Procedures
- Drill the seven hands-on domains (T 19/C29, T 112/C142, T 113/C123, T 176/D2419, T 304/C1252, D4791, D5821) using CP-45 procedure steps
Full Practice Runs
- Time a 100-question written mock exam at the two-hour limit; rehearse verbal descriptions for performance steps
Final Review Before Test Day
- Revisit any standard below your personal 60% comfort threshold; confirm calculator and reference materials meet exam rules
Practicing under realistic, timed conditions matters more than re-reading notes. You can run full-length timed simulations on our ATT2 practice test platform to see how your pacing across all ten standards holds up before you commit to a sponsoring group's scheduled date. If you're still deciding how much lead time to give yourself, how hard the ATT2 exam actually is is worth reading before you lock in a test date.
Prerequisite Timing: Level 1 Comes First
Certification requires a current ACI Aggregate Testing Technician - Level 1 credential before you're eligible to sit for ATT2. This isn't a formality - sponsoring groups verify Level 1 status as part of registration, and scheduling an ATT2 session without a current Level 1 credential in hand will delay or block your enrollment entirely.
If your Level 1 certification is nearing its own renewal window, factor that into your ATT2 timeline. Full eligibility mechanics, including what "current" means for the Level 1 prerequisite, are covered in the ATT2 requirements and eligibility guide.
Recertification: Planning for Year Five
ATT2 certification lasts five years. Recertification requires passing both the written and performance examinations again - there's no abbreviated renewal path or continuing-education substitute. That means your first passing date effectively sets a second future deadline on your calendar: mark it now, five years out, so recertification scheduling doesn't sneak up on you the way an expired credential can disrupt project bidding or job assignments.
Because sponsoring groups schedule sessions independently, start checking availability for recertification testing several months before your five-year mark rather than waiting until the credential lapses.
Key Takeaway
Treat your ATT2 certificate date as two calendar entries: the pass date itself, and a reminder roughly five years later to begin scheduling recertification with an approved sponsoring group.
Frequently Asked Questions
No. ATT2 exams are administered through ACI-approved sponsoring groups and examiners, each setting their own 2026 session dates rather than following one national calendar.
Contact ACI-approved sponsoring groups in your region directly - such as chapter organizations or ready-mix associations that run certification courses - since scheduling and registration deadlines are set locally.
Not necessarily. Sponsoring groups structure sessions differently, but both components must be passed within one year of each other regardless of whether they're scheduled together or separately.
A component whose one-year validity period has lapsed no longer counts, meaning you would need to retake that component in full and pass it again within a new one-year window relative to the other component.
No. A current ACI Aggregate Testing Technician - Level 1 credential is a prerequisite, and sponsoring groups verify this before allowing ATT2 registration.
Whatever sponsoring group's 2026 calendar you end up scheduling around, treat the date itself as a fixed constraint and work your domain-by-domain preparation backward from it. For a condensed final-review resource once your test date is locked in, the ATT2 cheat sheet and continued timed practice on our practice exam site are the fastest way to confirm you're ready before walking into either exam component.
