ATT2 Pass Rate 2026: What the Data Shows

The ATT2 Pass Rate Question: What's Actually Published

Anyone searching for a single "ATT2 pass rate" number for 2026 will come up empty. ACI does not publish aggregate pass/fail statistics for the Aggregate Testing Technician - Level 2 credential, and no sponsoring group - including the ACI Intermountain Chapter or CRMCA - releases pass-rate data for their local sessions. What ACI does publish, in detail, is the scoring structure that determines who passes and who doesn't. That structure is far more useful than a headline percentage, because it tells you exactly where the risk sits before you ever walk into the room.

Instead of chasing an unverified statistic, this article breaks down the actual pass/fail mechanics defined in CPP 620.3-20 (revised September 21, 2020) and the Job-Task Analysis approved September 30, 2024, so you can see precisely how a candidate's outcome is calculated. If you want the full domain breakdown behind these standards, the ATT2 Exam Domains 2026 guide maps all ten in detail.

Why ATT2 Has Two Separate Pass/Fail Hurdles

ATT2 certification requires clearing two independent components, and each has its own failure mode:

• Written examination: open-book (ACI-approved references only), two hours, roughly 100 multiple-choice questions, with eight to 12 questions drawn from each of the ten standards.
• Performance examination: closed-book, requiring correct physical demonstration or ACI-permitted verbal description of prescribed procedure steps.

Because these are scored and administered separately, a candidate can pass the written exam cleanly and still fail certification outright on the performance side, or vice versa. This is a structural feature unique to how ATT2 is built - a factor generic "exam difficulty" content misses entirely. For a deeper look at how the two components compare in difficulty, see How Hard Is the ATT2 Exam? Complete Difficulty Guide 2026.

The Scoring Mechanics That Drive Outcomes

The written exam's passing rule is stricter than it first appears. It's not enough to hit 70% across the whole 100-question set - a candidate must also score at least 60% within each individual standard. With only eight to 12 questions per standard, that 60% threshold translates to a very small margin for error: missing five or six questions in a single weak standard can fail that entire block even if your overall score clears 70%.

This dual-threshold design means memorizing broad concepts isn't sufficient. A candidate needs working competence in all ten standards individually - not just an average grasp across the exam. This is the exact reason blanket "study everything generally" advice underperforms for ATT2 candidates; targeted, standard-by-standard review matters more here than on single-threshold exams. The ATT2 Passing Score 2026 breakdown walks through this math in more depth.

Domain-by-Domain Risk: Where Candidates Lose Points

Seven of the ten Job-Task Analysis domains carry both written and performance-exam weight, while three are written-only. Knowing which is which changes how you allocate study time.

Since the performance exam is closed-book, procedural sequencing for these seven standards has to be committed to memory - you cannot flip to CP-45 mid-demonstration the way you can during the written portion. Candidates who treat the two exams identically in their prep often underestimate this gap. The ATT2 Study Guide 2026 covers sequencing drills for each practical standard.

The One-Year Window and Retake Rules

ATT2's certification clock adds another layer that affects outcomes: both the written and performance exams must be passed within a one-year window of each other. If you pass the written exam but fail the performance exam - or the reverse - the passed component stays valid for that year while you retake only the failed one. Miss the one-year mark, and the previously passed component's credit lapses; you're back to retaking it in full.

Who Actually Sits This Exam

ATT2 is not an entry-level credential. Certification requires an active ACI Aggregate Testing Technician - Level 1 credential first, which shapes who typically registers: aggregate producers, ready-mix and asphalt QC labs, DOT-adjacent materials testing firms, and construction materials engineering companies sending existing lab technicians for advancement. Because the prerequisite already filters out unqualified candidates, the written and performance exams assume a working familiarity with basic aggregate sampling and testing - the JTA builds on Level 1 knowledge rather than starting from zero. If you're unsure whether you meet the prerequisite path, the ATT2 Requirements 2026 guide covers eligibility in full.

A Domain-Aligned Prep Timeline

Rather than a generic weekly study template, an ATT2-specific schedule should sequence around the written-only versus practical-standard split described above, since the two require different study modes.

Full-length practice sets scored this way are exactly what you'll find on the main ATT2 practice test platform - reviewing results by standard, rather than a single composite score, mirrors how ACI actually grades the exam.

Fee Context and Why It Matters for Retakes

Fees are set locally by ACI sponsoring groups, not nationally, and packages vary. Two published 2026 examples illustrate the range: the ACI Intermountain Chapter in Utah charges USD 500 for chapter members or USD 600 for nonmembers, bundling the study guide, review session, written exam, and performance exam. CRMCA's session at Denver's CDOT headquarters charges USD 598 for members or USD 928 for nonmembers for the full exam, with workbooks purchased separately, no exam-day training or review included, and a 3.05% credit-card processing fee. The standalone CP-45 seventh-edition workbook runs USD 133 regular or USD 69 for ACI members if purchased outside a bundled package.

These are named local packages, not a single national ACI price - a detail worth confirming with your sponsoring group before registering. Because retaking a failed component means paying for that portion again, understanding what each local package does and doesn't include is directly tied to how costly a failed attempt becomes. The ATT2 Certification Cost 2026 breakdown compares these packages line by line.

Certification itself lasts five years, after which recertification requires passing both the written and performance exams again - the same two-hurdle structure applies at renewal as it does the first time.
