- Autodesk does not publish an official ACA pass rate for 2026 or any prior year.
- Domain 1 (3D component modeling) carries 61% of the exam - master it first.
- The exam has 45-60 questions in 120 minutes, with no Fusion software access during testing.
- After one fail you can often reschedule immediately; after two or more, you wait 72 hours.
Why There's No Official ACA Pass Rate
If you searched for "ACA pass rate 2026" hoping to find a single published percentage from Autodesk, you won't find one. Autodesk does not release official pass/fail statistics for the Autodesk Certified Associate in CAD for Mechanical Design exam, and neither Pearson VUE nor Autodesk's certification support pages break down scores by domain, region, or attempt number. This is common across vendor-specific IT and design certifications - the credentialing body controls messaging around difficulty rather than publishing raw numbers.
That means any specific pass-rate percentage you see floating around forums or third-party blogs is either outdated, unofficial, or borrowed from an entirely different credential that happens to share the "ACA" acronym. This article will not invent a number to fill that gap. Instead, it uses what's actually documented - exam structure, domain weighting, question format, retake rules, and renewal mechanics - to explain what actually drives whether a candidate passes.
What Data Actually Exists
Since there's no published pass rate, the only reliable "data" a candidate can work with is the structure of the exam itself, as defined in the October 2024 objectives document. Here's what's confirmed:
- 45-60 selected-response questions, delivered in a single 120-minute session
- Question types include multiple choice, drag-and-drop, active-screen, hot-area, and graphic interpretation
- Fusion software is not available during the test - you cannot open the application to check your answer
- Scoring is reported as pass/fail only, with no scaled score breakdown released to candidates
- Delivery is available at Pearson VUE testing centers or via OnVUE online proctoring, in English
None of this tells you a percentage of people who pass. But it does tell you exactly what kind of preparation reduces risk: familiarity with Fusion workflows without relying on the software mid-exam, and comfort with interface-based question formats like hot-area and active-screen items.

Key Takeaway
Treat the absence of a published pass rate as a reason to prepare more rigorously, not less - you can't benchmark against a known bar, so aim to overperform every domain rather than scrape by on the weakest one.
Domain Weighting and Why It Predicts Difficulty
The single biggest factor influencing whether a candidate passes is how well their study time matches the exam's domain weighting. The October 2024 objectives define three domains:
| Domain | Weight | Practical Implication |
|---|---|---|
| 3D Component Modeling and Project Files | 61% | Majority of questions; weakness here is fatal to a pass attempt |
| 3D Assembly Modeling and Management | 24% | Second priority; assembly logic and constraints matter |
| Technical Detailed Drawing Creation | 15% | Smallest share, but still tested with specific formats |
Because Domain 1 alone accounts for well over half the exam, a candidate who is strong in assemblies and drawings but shaky on component modeling and project file structure is statistically likely to fail - even though they "know two out of three domains well." This is the single most actionable insight available in the absence of a published pass rate: allocate study time proportionally to the 61/24/15 split, not evenly across three topics.
Domain 1: 3D Component Modeling and Project Files (61%)
Candidates need fluency with feature-based modeling, parametric design intent, sketch constraints, and how Fusion organizes project files and data.
- Sketch and constraint-based modeling logic
- Feature creation order and its effect on downstream edits
- Project file organization and data management within Fusion
Domain 2: 3D Assembly Modeling and Management (24%)
This domain checks whether a candidate can build and manage multi-component assemblies correctly.
- Joint types and assembly constraints
- Component relationships and motion behavior
- Managing assembly structure as designs grow more complex
Domain 3: Technical Detailed Drawing Creation (15%)
The smallest domain by weight, but drawing-output questions still appear in hot-area and graphic-interpretation formats.
- Generating drawing views from 3D models
- Annotation, dimensioning, and drawing standards basics
- Reading and interpreting technical drawing output

How the Question Format Affects Outcomes
Pass rates for any exam are shaped as much by format as by content knowledge. The ACA exam mixes multiple choice with drag-and-drop, active-screen, hot-area, and graphic interpretation items - and critically, Fusion itself is not accessible during the test. That last detail changes how you should prepare.
Candidates who learn Fusion only by clicking around inside the software, without ever pausing to explain menu locations, toolbar icons, or dialog-box options out loud, often struggle with hot-area and active-screen questions because those formats ask you to identify the correct interface element from a static image rather than from live software. Building interface recall - not just task completion - is a distinct skill from just "knowing Fusion."
What the Retake Policy Tells Us
Autodesk's retake policy is one of the few concrete signals candidates can use to gauge how the exam is meant to be taken seriously rather than gamed. After a first failed attempt, you may be able to reschedule immediately, subject to seat availability. After a second failed attempt - and any subsequent fail - you must wait 72 hours before retesting.
This structure implies the exam is not designed for rapid-fire retries. A candidate who fails twice is expected to take at least three days to review missed material before trying again, which strongly suggests Autodesk wants failed attempts to trigger real study, not repeated guessing. Combined with the US$200 standard retail exam fee (confirm your specific checkout price, since Autodesk's general Associate fee table separately lists US$150), repeated failed attempts get expensive quickly. Full fee mechanics and what's included at each price point are broken down in ACA Certification Cost 2026: Complete Pricing Breakdown.
Key Takeaway
Budget for one serious attempt rather than planning to "learn the exam" through multiple retakes - the 72-hour wait after a second fail, plus the exam fee, makes repeated attempts costly in both time and money.
Who Tends to Pass - and Who Struggles
Without official statistics, the most useful qualitative signal comes from who this certification is actually built for. Autodesk positions the ACA in CAD for Mechanical Design as an early-career or student-level credential validating Fusion competency - the kind of skill employers in manufacturing, product design, and engineering-support roles look for when screening entry-level CAD technicians and design assistants. Roughly 150 hours of relevant Fusion experience is cited as preparation guidance, not a hard prerequisite, which tells you Autodesk expects candidates to arrive with meaningful hands-on time already logged.
Candidates who tend to struggle are usually those who:
- Have theoretical CAD knowledge from a different platform but limited hands-on Fusion time
- Underweight Domain 1 because they assume "modeling" is the easy part
- Haven't practiced the specific question formats (hot-area, active-screen, drag-and-drop) before test day
- Walk in without understanding the registration mechanics - Autodesk Account setup, identity verification, and OnVUE proctoring requirements - and lose focus to logistics stress

A Domain-Weighted Prep Timeline
Generic study techniques like spaced repetition or timed practice blocks only help if they're pointed at the right material in the right proportion. Given the 61/24/15 domain split, a study schedule should mirror that weighting rather than splitting time evenly across three domains.
Domain 1 Deep Dive
- Feature-based modeling and parametric sketch constraints
- Project file structure and data organization inside Fusion
- Practice identifying toolbar and dialog elements from static screenshots
Domain 2 Focus
- Assembly joints, constraints, and component motion
- Managing assembly structure as models grow in complexity
Domain 3 and Full Review
- Drawing view generation, annotation, and dimensioning basics
- Full-length timed practice covering all question formats
- Registration and logistics check: Autodesk Account, ID verification, testing method
This is a compressed version of the full plan available in ACA Study Guide 2026: How to Pass on Your First Attempt, which goes deeper into resource selection and practice routines for each week. Running timed practice sets on a full practice test platform before test day is one of the more reliable ways to simulate the 120-minute, no-software-access format ahead of the real thing.
The Cost of Failing an Attempt
Because Autodesk doesn't publish pass-rate data, it's worth thinking about failure risk in terms of what it actually costs rather than a probability you can't verify. Each attempt carries the exam fee (confirm your exact price against the credential-specific listing before checkout), plus the 72-hour minimum wait after a second failure before you can try again. If certification is tied to a job application deadline, a course requirement, or a renewal window, that wait time matters.
Renewal adds another layer worth planning for early: the credential is valid for three years, and renewal requires submitting a new application during the final six months, then purchasing and passing the exam again before expiration - there is no grace period. Treating your first attempt as the only attempt you plan for, rather than a "practice run," is the most realistic way to think about pass/fail odds without an official statistic to lean on. Exact scoring thresholds and how the pass/fail determination works are covered in ACA Passing Score 2026: Exactly What You Need to Pass, and current testing windows are listed in ACA Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
