ACA Exam Dates 2026: Testing Windows, Deadlines & Scheduling

How ACA Exam Scheduling Works in 2026

Unlike college entrance exams or some professional licensing tests, the Autodesk Certified Associate in CAD for Mechanical Design exam doesn't operate on quarterly windows or announced 2026 test dates. Autodesk delivers this credential through Pearson VUE, which means scheduling is candidate-driven and available essentially every day of the year, limited only by test center capacity or OnVUE online proctoring availability at the time you book.

That's good news if you're trying to plan around a semester, a job application deadline, or a certification requirement at work - you pick the date, not Autodesk. But it also means there's no "registration period" to wait for. If you're ready, you book. If you're not ready, understanding the exam domains and pacing your prep matters more than watching a calendar.

Testing Windows: No Fixed Dates, Year-Round Availability

Since the exam is delivered continuously rather than in batches, the real scheduling variables aren't calendar-based - they're logistical. Two delivery paths exist:

• Pearson VUE testing centers - in-person delivery at a physical test site, subject to that location's own appointment calendar and identity-check procedures.
• OnVUE online proctoring - remote delivery from your own computer, with identity verification handled through your webcam and an Autodesk Account tied to your registration.

Both paths require you to have an active Autodesk Account before you can register, so setting that up is the actual first "deadline" worth tracking - do it well before you intend to sit the exam, not the night before.

Registration Steps and Fee Confirmation

Booking the exam involves a few concrete steps, and getting them right avoids scheduling headaches later:

1. Create or confirm an active Autodesk Account, since registration is tied to it.
2. Locate the credential-specific exam listing for Autodesk Certified Associate in CAD for Mechanical Design rather than a general Associate-level bundle.
3. Choose Pearson VUE test center or OnVUE online proctoring based on what's available near your desired date.
4. Review pricing at checkout before confirming payment.

On pricing specifically: the credential-specific listing states a US$200 standard retail exam fee, but Autodesk's general Associate fee table elsewhere lists US$150. Because these figures can differ depending on where you're looking, always confirm the actual number shown at checkout before you finalize your booking - don't assume either figure without seeing it applied to your registration. For a full breakdown of what you might pay and why the numbers vary, see our certification cost breakdown.

What Happens on Exam Day

Whether you test in a Pearson VUE center or through OnVUE at home, the exam experience itself is identical. You'll answer 45-60 questions within a 120-minute window, delivered entirely in English for both the exam content and the proctor interaction. Question formats include:

• Multiple choice
• Drag-and-drop
• Active-screen interactions
• Hot-area selections
• Graphic interpretation questions

One detail that surprises first-time candidates: Fusion software itself is not available during the exam. You're being tested on your knowledge of Fusion workflows, terminology, and design logic through selected-response questions and graphic-based items - not through live modeling inside the application. That changes how you should prepare, since flawless mouse skills in Fusion don't automatically translate into exam-ready recall. Results are reported simply as pass/fail, with no scaled score breakdown. If you want the specifics on what "passing" actually requires, our passing score guide covers that in detail, and our difficulty guide breaks down why the no-software format catches people off guard.

The Three Domains You're Scheduling Time Around

Your exam date should be set based on how much time you realistically need to cover three weighted domains defined in the October 2024 objectives. These aren't equally weighted, so your prep schedule shouldn't treat them equally either.

For a full walkthrough of subtopics within each domain, see our complete domains guide. Roughly 150 hours of relevant Fusion experience is offered as preparation guidance by Autodesk - it's not a mandatory prerequisite, so you can schedule your exam earlier or later than that benchmark depending on your own background. Our requirements article explains what's actually mandatory versus recommended.

Rescheduling After a Failed Attempt

If your first attempt doesn't go as planned, the rescheduling rules matter for how quickly you can plan a retest:

• After a first failed attempt: rescheduling may be immediate, subject to test center or OnVUE appointment availability.
• After a second or subsequent failed attempt: you must wait 72 hours before scheduling again.

This means your retake timeline compresses quickly if you pass on attempt two, but stretches out with repeated attempts. If you're unsure how likely a first-pass outcome is, our pass rate analysis and first-attempt study guide are worth reading before you lock in your original date, so you're not scrambling to understand the retake rules mid-cycle.

Renewal Deadlines: The Three-Year Clock

Passing the exam isn't the end of the scheduling conversation - certification is valid for three years, and renewal has its own strict timing:

• You must submit a new application during the final six months before your certification expires.
• Renewal requires purchasing and passing the exam again before the expiration date.
• There is no grace period - missing the window means the certification lapses rather than extends.

If you earned your credential in 2023 or earlier, mark your renewal window now rather than waiting for a reminder. Set a calendar alert for six months before your three-year anniversary so you have time to schedule a Pearson VUE or OnVUE session without rushing.

Building a Study Timeline Around Your Exam Date

Once you've set a target exam date, work backward using the domain weights rather than splitting time evenly across topics. A simple four-week structure illustrates the logic - adjust the number of weeks to match your own availability and the 150-hour guidance figure.

Notice that roughly half the schedule stays on Domain 1 alone - that mirrors its 61% weight on the actual exam. Trying to give each domain equal study time is a common planning mistake covered in more depth in our study guide.

Online Proctoring vs. Test Center: Which Fits Your Schedule

Choosing between OnVUE and an in-person Pearson VUE center often comes down to what dates and locations are actually open near you, but the two options do differ in a few scheduling-relevant ways.

If you have an unreliable internet connection or a workspace that's hard to keep private and quiet, a test center may be the more dependable scheduling choice. If travel time is your bigger obstacle, OnVUE removes that variable entirely - provided your setup passes the pre-exam system check.

And if you want a quick reference of every exam-day fact in one place while you finalize your booking, our one-page cheat sheet is built exactly for that. You can also work through timed practice scenarios on our practice test platform before you commit to a date, so your scheduling decision is based on real readiness rather than a guess.
