- The Certified Onshape Associate passing mark is 75% of total points, not 75% of questions.
- The current listing has 48 questions: 14 Modeling questions worth 66 points and 34 knowledge questions worth 34 points.
- Modeling carries roughly two-thirds of all available points, so CAD performance decides most attempts.
- The exam allows 3 hours and costs $50 per attempt, so a failed try has a real price.
The Passing Score at a Glance
The Certified Onshape Associate (COA) exam, delivered through the Onshape Learning Center and developed with SolidProfessor, sets one clear bar: you must earn 75% of the available points. That is the whole passing rule. There is no separate minimum for each section published in the sources we reviewed, and no curve is described. You either clear the 75% line or you do not.
What trips people up is that the exam is scored by points rather than by simple question count. The two sections are weighted very differently, so a candidate who treats all 48 questions as equal will misjudge where their effort belongs. This guide explains exactly how the points are distributed, what 75% looks like in practice, and how to build a plan around it.
| Exam Element | Current Listing |
|---|---|
| Credential | Certified Onshape Associate (Onshape, a PTC business) |
| Total questions | 48 |
| Modeling section | 14 questions / 66 points |
| Knowledge-based section | 34 questions / 34 points |
| Time allowed | 3 hours |
| Passing threshold | 75% of points |
| Fee | $50 per attempt |
How Points Work Across the Two Sections
The exam splits into two scored sections that behave very differently. Together they create a 100-point scale, which makes the arithmetic easy: 75% of points means 75 out of 100 on the current listing.
Domain 1: Modeling Section
The Modeling section contains 14 questions worth 66 points. These are the hands-on CAD tasks, where you build or edit geometry in Onshape and submit results. Because the section holds 66 of the 100 points, it is the heavier half of the exam by a wide margin. The per-question point value is not published in the sources we verified, so do not assume every modeling question is worth the same amount.
Domain 2: Knowledge-Based Section
The Knowledge-based section contains 34 questions worth 34 points, which works out to one point per question. These are multiple-choice items that test whether you understand how Onshape works, rather than whether you can execute a build under time pressure.
What 75% Means in Practice
Because the two sections sum to 100 points, you need 75 points to pass. Here is how that can break down. These are illustrations of the arithmetic, not predictions of how any candidate will actually score.
| Scenario | Knowledge Points (of 34) | Modeling Points Needed (of 66) |
|---|---|---|
| Perfect knowledge section | 34 | 41 |
| Strong knowledge section | 30 | 45 |
| Moderate knowledge section | 26 | 49 |
| Weak knowledge section | 20 | 55 |
Two lessons follow from this table. First, even a flawless knowledge section does not carry you: you still need roughly 41 modeling points. Second, every knowledge point you drop pushes the modeling requirement up by one. A candidate who is shaky on the multiple-choice side has to be nearly flawless at the CAD bench.
Key Takeaway
Treat the knowledge section as your safety margin. It is the more predictable 34 points, and banking most of them lowers the modeling score you need. Then use the modeling section to close the gap. For a candid look at how demanding the whole exam is, read How Hard Is the COA Exam?
Winning Points in the Modeling Section
With 66 points riding on 14 questions, the Modeling section is where passing is usually decided. The official preparation guidance describes this as hands-on CAD work, so success depends on fluency inside Onshape rather than on memorization.
Skills That Earn Modeling Points
Core Onshape Modeling Fluency
Modeling questions reward candidates who can move from a drawing or specification to correct geometry efficiently. Practice these areas until they are automatic:
- Creating fully defined sketches with dimensions and constraints
- Extruding, revolving, and cutting to build solid parts
- Applying fillets, chamfers, and holes at the right stage of the feature tree
- Using patterns and mirrors to avoid repetitive work
- Working in Part Studios and understanding how parts relate to assemblies
- Reading dimensions carefully so the final part matches the stated geometry
Why Precision Matters
In a hands-on CAD exam, a part that is almost right can still be wrong. A dimension entered in the wrong unit, a sketch that is not closed, or a cut applied to the wrong face can cost points on a question you understood conceptually. When reviewing your own practice builds, check measurements against the specification before moving on, rather than assuming the visual looks correct.
Because the weighting is heavy, it is worth building your preparation around real Onshape time rather than reading alone. Our COA study guide lays out how to structure that practice.
Winning Points in the Knowledge-Based Section
The 34 knowledge questions are each worth one point, so no single item can sink you, but together they form a third of the total. The best approach is steady accuracy: a handful of misses is fine, while a pattern of misses in one topic is a warning sign.
What the Knowledge Section Tests
These multiple-choice questions probe your understanding of how Onshape behaves as a cloud-based CAD platform. Focus on:
- Terminology: what a Part Studio, Assembly, Feature, and Document each are
- How the feature tree and rollback bar work
- Version and branching concepts that distinguish Onshape from file-based CAD
- Sharing, collaboration, and permissions at a conceptual level
- Selecting the appropriate tool or feature for a stated design goal
Official preparation tips describe reference access, so familiarize yourself with what resources are permitted and how to use them quickly. Do not rely on lookups for fundamentals, since time spent searching is time taken from the modeling questions.
Scoring Strategies for a 3-Hour Window
You have 3 hours for 48 questions, which is generous for the knowledge items but tight if modeling tasks run long. Since the modeling questions hold most of the points, time discipline matters more than speed on the multiple-choice side.
Suggested Approach to Sequencing
- Skim the whole exam first. Knowing how many modeling tasks remain helps you budget time.
- Bank the knowledge points efficiently. These are one point each; answer what you know and flag the rest.
- Protect your modeling time. Give the 14 modeling questions the largest share of the 3 hours, since they carry 66 points.
- Verify before you submit. Re-check dimensions and constraints on any modeling question you rushed.
Scheduling Prep Around the Point Split
Because the points are lopsided, your preparation hours should be too. This is the one place where a study schedule helps, and it is tied directly to how the score is built: heavy on hands-on modeling, with the knowledge section reinforced alongside it. Adapt the timeline to your own starting point.
Modeling Foundations
- Drill sketching, constraints, and dimensioning in Onshape
- Build basic parts with extrudes, cuts, and revolves
Advanced Modeling and Assemblies
- Practice patterns, mirrors, fillets, and multi-feature parts
- Work through Part Studio and assembly relationships
Knowledge-Based Review
- Review Onshape terminology, feature tree behavior, and collaboration concepts
- Take practice questions and log any recurring misses
Timed Full-Length Rehearsal
- Simulate the 3-hour format with modeling and knowledge questions together
- Score yourself against the 75% line and revisit weak spots
You can test your knowledge-side readiness on our COA practice tests, then pair that with timed building sessions in Onshape. The COA cheat sheet is useful for a quick pre-exam refresher on terminology.
Attempt Economics: The Cost of Falling Short
The exam fee is $50 per attempt. Conditional vouchers and bulk discounts exist, so it is worth checking whether you qualify before paying full price, especially if you are enrolling as part of a class or group. Our COA certification cost breakdown covers the pricing details.
The score requirement and the fee interact in a simple way: a missed 75% means paying again. We could not verify definitive retake rules, so check the official listing at the time you register rather than assuming a waiting period or a discount for repeat attempts. The practical conclusion is to prepare to pass on the first try, since that keeps your total cost at a single attempt.
Passing earns a certificate and badge. If you are weighing whether that credential justifies the effort, see Is the COA Certification Worth It? and the COA salary guide for the career-side picture.
What Is Not Published About the Score
Honesty about the gaps is part of useful guidance, so here is what we could not confirm from official sources:
- Per-question modeling values. The section totals 66 points across 14 questions, but individual weights are not listed.
- Partial credit rules. Whether a nearly correct modeling submission earns some points is not stated in the material we reviewed.
- General pass rate. No verified figure exists, which is why our COA pass rate article stays qualitative.
- Expiration and renewal terms. Definitive details were not verified.
- Formal proctoring specifications. These were not verified either.
Relevant experience is recommended rather than enforced as a formal admission threshold, so most people can attempt the exam without a documented prerequisite. For eligibility context, see COA requirements, and for scheduling, check COA exam dates.
Key Takeaway
Plan around what is confirmed: 75% of points, 66 modeling points, 34 knowledge points, 3 hours. Anything beyond that, verify on the official Onshape Learning Center listing before you rely on it.
Frequently Asked Questions
You must earn 75% of the available points. On the current listing the exam totals 100 points across its two sections, so that equates to 75 points.
The current listing totals 48 questions: 14 in the Modeling section worth 66 points and 34 in the Knowledge-based section worth 34 points. Older references to 45 questions describe the historical launch format.
Not necessarily. Scoring is by points, and the Modeling section holds about two-thirds of them. The percentage of questions you answer correctly can differ from your percentage of points earned.
The exam allows 3 hours. Because the modeling questions carry the most points, reserve the largest share of that time for them.
The fee is $50 per attempt, with conditional vouchers and bulk discounts available in some cases. Definitive retake policies were not verified, so confirm current terms with the official listing before registering again.
Understanding the scoring math turns the passing requirement from a vague target into a concrete plan: secure the steady knowledge points, invest your hands-on practice in the 66-point modeling section, and use the full 3 hours wisely.
