- No verified published pass rate exists for the CSWP-API; any specific percentage you see online is unsourced.
- The 70-point passing score on a 100-point exam is a threshold for your result, not a population statistic.
- Eighteen of the 28 questions are hands-on automation tasks, so VBA fluency matters more than memorization.
- Retakes need a new credit and a wait of at least 14 days, so one prepared attempt beats two rushed ones.
Why No Verified Pass Rate Exists
If you searched for the CSWP-API pass rate hoping for a clean number, here is the honest finding: published population pass rates for the Certified SOLIDWORKS Professional API exam were not verified. SOLIDWORKS, the Dassault Systemes brand that governs the credential, does not publish a pass-rate figure on its exam page, in the linked Certification Exam Guide & Practice Test, or in its certification program FAQ. The exam is delivered through Tangix/VirtualTester, and nothing in the public materials discloses how many candidates attempt or pass it.
That matters for how you read the rest of the internet. Training vendors, forum posts and course landing pages sometimes quote success figures, but without a methodology or a primary source those numbers cannot be treated as data. This article takes a different approach: instead of inventing a statistic, it shows what the verifiable facts about the exam imply for your odds, and where candidates are most likely to lose points.
The 70% Passing Grade Is Not a Pass Rate
The most common confusion in this space is mixing up two very different numbers. The CSWP-API passing grade is 70 points out of 100. That is the score you personally need to earn. A pass rate, by contrast, would describe what share of all candidates reach that score. The first is published; the second is not.
| Metric | What it means | Verified for CSWP-API? |
|---|---|---|
| Passing grade | Points an individual needs to pass | Yes: 70 of 100 points |
| Pass rate | Share of all candidates who pass | No published figure verified |
| Exam length | Time allowed for the attempt | Yes: 120 minutes |
| Question count | Items on the exam | Yes: 28 (18 hands-on tasks, 10 multiple choice) |
| Certificate validity | How long the credential lasts | Per the issuer's 2020 Q&A, customer and student certifications do not expire |
For a full breakdown of how scoring works, read what you need to pass the CSWP-API. The short version: the threshold is fixed and public, so your preparation target is concrete even though the population statistics are not.
Exam Structure: Where Candidates Actually Lose Points
Without a pass rate, the most useful data is structural. The exam's design tells you where difficulty concentrates.
18 hands-on tasks versus 10 multiple-choice questions
Roughly two thirds of the exam by question count consists of hands-on automation tasks written in Visual Basic for Applications (VBA). The remaining ten questions are multiple choice. This split is the single most important fact for anyone estimating their chances. A candidate who knows SOLIDWORKS modeling well but has never written a macro from scratch is exposed on the majority of the exam. A candidate who can write and debug VBA but is rusty on API terminology may still recover points on the tasks.
The official sample is small
The issuer-linked guide contains only four multiple-choice sample questions. It is not a complete 28-question mock, and it contains no worked example of the 18 hands-on tasks. Candidates who prepare solely from that document have seen a small slice of the multiple-choice style and none of the automation workload. This gap is a likely driver of surprise on exam day, and it is why original practice macros matter. Our CSWP-API study guide covers how to build that practice without relying on leaked or recalled questions.
Non-proctored, no pause
The guide describes a non-proctored online exam taken on your own working SOLIDWORKS installation and Internet connection, with SOLIDWORKS 2017 or later as the minimum. The exam cannot be paused. Follow the current VirtualTester Web Client instructions rather than the guide's legacy TesterPRO installation and crash language, since the current browser-client and recovery instructions take precedence. A flaky connection or an unstable SOLIDWORKS session is a risk you control before you click start.
Where the Evidence Points: Likely Failure Points by Domain
The issuer lists 15 exam objectives, unweighted and explicitly non-exhaustive. We do not assign percentages to them. What we can do is reason about which areas demand the most from a candidate, based on how much code each requires. Treat the following as editorial judgment, not measured failure data.
Understanding the API Object Model
Everything else depends on navigating from the application object down to documents, features, entities and their properties. Candidates who memorize snippets without understanding the hierarchy stall as soon as a task deviates from the pattern.
- Know how to move from the application object to the active document and its manager objects
- Practice using API Help to find the right interface and method signature
- Understand the limits of the macro recorder, which produces verbose and brittle code
Troubleshooting
Hands-on tasks rarely run perfectly the first time. Reading return values, handling Nothing objects, and diagnosing a failed selection or feature call are skills the exam rewards.
- Check return values and boolean results rather than assuming success
- Use the VBA debugger, breakpoints and the Immediate window
- Recognize common causes: wrong document type, failed selection, missing reference
Selection and Traversal Techniques
Selecting the correct face, edge, component or feature programmatically, and walking the feature tree or component list, is a frequent stumbling block because it requires both geometry awareness and precise API calls.
- Practice selecting by name, by type and by coordinate
- Traverse features and components in a loop and test their types
- Learn how selection marks and selection managers affect later calls
Sketches, Dimensions and Features
The objectives for adding sketch entities and dimensions, and creating features such as extrudes and cuts, form the core of part design automation. These tasks chain several calls together, so an error early in the sequence breaks everything downstream.
- Create a sketch, add entities, dimension them, then build the feature
- Verify each step before moving to the next
Drawing Automation
Several objectives concern drawings: creating them, inserting views, inserting a BOM, and saving in different file formats. The issuer lists overlapping drawing headings, and we retain them as written. Drawing tasks require a template, a model reference and correct view parameters.
- Create a drawing from a template and place views of a model
- Insert a bill of materials and confirm it populates
- Save the drawing in more than one file format
Assembly Automation and Component States
Hide, suppress and resolve operations on components, plus general assembly automation, combine selection skills with state management. Candidates often confuse suppression, lightweight and resolved states.
- Distinguish hiding from suppressing and resolving
- Iterate over components and change their state programmatically
Custom Properties, Saving and Closing
Adding custom properties and saving and closing documents are the most mechanical objectives. They are also where easy points are lost to small errors, such as saving to an invalid path or leaving documents open.
- Add and read custom properties at file level
- Save and close documents cleanly and check the result

How to Read Pass-Rate Claims You Find Online
Search results for this credential come from several kinds of sources: direct exam advice, API training, free automation tutorials and course listings, including some in other languages. These serve different purposes, and none of the observed ones establishes a verified population pass rate. When you encounter a claim, run it through four checks.
- Is there a named primary source? A figure attributed to "the exam provider" with no link or document is not verifiable.
- Is it the right credential? Several certifications share the CSWP-API acronym in various contexts. Confirm the claim refers specifically to the SOLIDWORKS API Professional exam delivered through Tangix/VirtualTester.
- Is the sample defined? A success rate among one training company's students describes that company's students, not all candidates.
- Is the date stated? The live exam page and linked guide are undated, so any claim about "current" results deserves extra suspicion.
Key Takeaway
A vendor's student success rate is a marketing statistic about a self-selected group. It says little about what a typical independent candidate should expect, and it cannot substitute for a verified population pass rate.
Readiness Signals That Beat Any Statistic
Since you cannot benchmark yourself against a published pass rate, benchmark against the task. These signals are more reliable than any number you could find.
- You can start from an empty VBA module. Open a new macro with no recorder output and build a part, a sketch and a feature using API Help alone.
- You can navigate the object model without a cheat sheet. Given an unfamiliar object, you can locate its methods in the help system within a minute or two.
- You debug quickly. When a call returns Nothing or False, you have a routine for finding out why.
- You complete a drawing workflow end to end. Create the drawing, insert views, add a BOM, set custom properties and save in a second format.
- You handle component states. You can hide, suppress and resolve components in a loop without errors.
- You finish inside a time box. A full set of automation tasks fits within the 120-minute window with time to check results.

Retake Mechanics and the Cost of a Miss
The cost structure is a practical reason to treat the first attempt seriously. The issuer lists US$49 for one North American attempt, excluding software and training. If you do not pass, a retake requires a new CSWP-API credit and a wait of at least 14 days. The exam is also not pausable and runs as a single sitting.
The dollar cost is modest, but the 14-day wait and the need to re-prepare are the real expense, especially if you are scheduling around work. Fees and regional pricing can vary, so check the current SOLIDWORKS certification program page and read our CSWP-API certification cost breakdown before you buy a credit. If you are weighing whether the investment pays off professionally, the ROI analysis of the CSWP-API frames it around demonstrated automation value rather than an unsupported salary uplift.
Sequencing Your Preparation by Domain
Generic study advice is plentiful; what helps here is ordering the 15 objectives so that foundations come before the tasks that depend on them. The plan below is one reasonable sequence for a CAD user with limited programming background. Adjust the pace to your own schedule.
VBA basics and the object model
- Variables, loops, conditionals and error handling in the VBA editor
- Navigating from application to document objects using API Help
- Why recorded macros are a starting point, not a solution
Parts, sketches, dimensions and features
- Sketch entities and dimensions
- Extrudes, cuts and part design automation
- Troubleshooting failed calls as they happen
Selection, traversal and assemblies
- Selecting faces, edges and components
- Walking the feature tree and component list
- Hide, suppress and resolve states
Drawings, properties and file handling
- Creating drawings, inserting views and a BOM
- Custom properties, multiple save formats, closing documents
- Timed run-throughs of complete workflows
The reasoning: troubleshooting and the object model underpin everything, so they come first and stay in rotation throughout. Selection and traversal precede assemblies and drawings because both rely on it. Save-and-close and custom properties go last because they are quick to learn but easy to forget under time pressure.
Remember that VBA exam preparation is distinct from C# add-in development and from PDM API work. Time spent on those topics will not help with this exam's VBA focus. For training options, see CSWP-API training resources.
Frequently Asked Questions
No published population pass rate was verified for the Certified SOLIDWORKS Professional API exam. The 70% figure you may see is the passing grade, meaning 70 of 100 points, not the share of candidates who pass.
You need 70 points out of 100. The exam has 28 questions: 18 hands-on automation tasks and 10 multiple-choice questions, with 120 minutes allowed.
Yes. A retake requires a new CSWP-API credit and a wait of at least 14 days. The fee listed for one North American attempt is US$49, excluding software and training, so confirm current pricing before purchasing.
Only partly. The issuer-linked guide contains four multiple-choice sample questions, not a full 28-question mock, and it does not include worked examples of the 18 hands-on tasks. Supplement it with original practice macros.
According to the issuer's 2020 Certification Program Q&A, customer and student certifications do not expire. Check the current SOLIDWORKS certification pages for any later policy changes.
The absence of a verified pass rate is not a reason to feel uncertain about your odds. The exam's structure is public, the passing score is fixed, and the objectives are listed. Your result will depend far more on whether you can write, run and debug VBA against SOLIDWORKS than on any population statistic.
