- Five education-plus-experience routes qualify you for CAWI; the shortest is high school plus 2 years of qualifying experience.
- No initial preparation training is mandatory - only documented education, employment, and a recent vision exam.
- You must score at least 60% on each of Part A, Part B, and Part C separately, not an averaged total.
- The 2026 initial fee is $1,255 for AWS members or $1,520 for nonmembers, including $120 in seat fees.
CAWI Eligibility Overview
Certified Associate Welding Inspector (CAWI) is an American Welding Society (AWS) credential built for people entering weld inspection who don't yet meet the experience threshold for full CWI status. Eligibility is defined almost entirely by a combination of education level and documented work experience - there is no requirement to complete a specific training course before you sit for the exam. That said, most candidates still study heavily before attempting the full CAWI certification exam line, because the content is dense and the scoring rules are unforgiving.
If you're still asking basic questions about what this credential is or how it differs from other inspection paths, start with What Is CAWI? or What Is A CAWI? before working through the eligibility mechanics below.
The Five Experience Routes to Qualify
AWS recognizes five combinations of education and qualifying work experience for CAWI eligibility. You only need to satisfy one:
- High school diploma (or equivalent) plus 2 years of qualifying experience - the fastest route for most candidates.
- Eighth grade education plus 4 years of qualifying experience.
- Less than eighth grade education plus 6 years of qualifying experience.
- Eighth grade education plus 1 year of vocational welding training plus 3 years of qualifying experience.
- 2 years of qualifying postsecondary study plus 6 months of qualifying experience.
Note how each route trades formal schooling against time in the field. A candidate with a two-year welding technology degree can qualify with only six months of relevant experience, while someone without a diploma needs six full years. This is a deliberate design: AWS wants assurance that candidates already understand welding fundamentals in some form - classroom, vocational shop, or hands-on job site - before letting them attempt the exam.
What Counts as "Qualifying Experience"
Experience generally needs to be relevant to welding, fabrication, or inspection-adjacent work rather than unrelated labor. AWS reviews the employment history you submit against the route you're claiming.
- Time in a welding trade, fabrication shop, or inspection support role typically counts.
- Purely clerical or unrelated industrial roles are unlikely to satisfy the requirement.
- Postsecondary study must be documented with transcripts, not just self-reported.
Documentation You Must Submit
Three categories of documentation back up your application:
- Education records - diploma, GED, transcripts, or vocational training certificates matching the route you're claiming.
- Employment history - verifiable records of the qualifying experience tied to your chosen route.
- A recent vision examination - because weld inspection is a visually demanding discipline, AWS requires current proof of adequate vision (including color discrimination where applicable) before you can be certified.
None of this requires formal preparation coursework. AWS explicitly does not mandate a prep class as a prerequisite - you're free to self-study using resources like a dedicated CAWI Study Guide or targeted practice questions on our practice test platform instead of paying for a classroom seat.
Key Takeaway
Gather your education records, employment verification, and a vision exam early - these are administrative bottlenecks, not academic ones, and they're easy to underestimate until you're ready to schedule.
How the Exam Line Confirms You're Ready
Meeting the eligibility routes above only gets you to the door. The actual exam line is where "qualifying" becomes "certified," and it's a multi-part, multi-appointment process - not one sitting. In total, the CAWI exam line spans 266 questions across 390 minutes of active testing, split into three separately scored parts:
- Part A (Fundamentals): 165 questions (150 scored, 15 pretest) in 135 minutes, closed-book, administered by Prometric.
- Part B (Practical): 46 questions in 120 minutes, paper-based and hands-on, administered at AWS-authorized sites using supplied specifications, weld replicas, and inspection tools.
- Part C (Code Book - D1.1): 55 questions (50 scored, 5 pretest) in 135 minutes, open-book code application, administered by Prometric.
You need at least 60% on each individual part - there is no averaging across parts. Score 75% on Part A and 55% on Part B and you still fail overall, because Part B fell short of the threshold. This structure is exactly why generic "study for the test" advice falls flat here; each part demands distinct preparation. For a full breakdown of exact score math, see CAWI Passing Score 2026, and for a topic-by-topic walkthrough of every domain, see CAWI Exam Domains 2026.
Minimum Subject Allocations by Part
Each part has published minimum percentage allocations for its subtopics - these are floors within that part, not fixed shares of the combined 266-question exam.
| Part A Topic | Minimum % |
|---|---|
| Definition and Terminology | 12% |
| Welding Processes | 12% |
| Symbols - Welding and NDE | 10% |
| Weld Examination | 10% |
| Welding Performance | 9% |
| Test Methods - NDE | 8% |
| Heat Control & Metallurgy | 6% |
| Welding Related Calculations | 6% |
| Duties and Responsibilities | 4% |
| Destructive Tests | 3% |
| Cutting | 2% |
| Part B Topic | Minimum % |
|---|---|
| Welding Inspection and Flaws | 34% |
| Procedure and Welder Qualifications | 28% |
| Mechanical Test and Properties | 8% |
| NDE | 8% |
| Utilization of Specification and Drawings | 8% |
| Part C Topic | Minimum % |
|---|---|
| Qualification | 25% |
| Fabrication | 25% |
| Inspection | 25% |
| Reports and Records | 5% |
| Materials and Design | 5% |
Notice how concentrated Part B is: Welding Inspection and Flaws plus Procedure and Welder Qualifications together account for a minimum of 62% of that part. That's not a coincidence - it reflects what employers actually need CAWI holders to do on a job site. Also worth watching: AWS B5.1:2025 updates terminology and merges Part A's welding and cutting content under "Joining and Cutting Processes" with a recommended minimum of 14%, so don't be surprised if study materials referencing the newer specification group these differently than older guides.
Fees and What They Include
For 2026, the initial CAWI exam line costs $1,255 for AWS members or $1,520 for nonmembers. Both figures include $120 in Part A/C seat fees paid to Prometric. The nonmember price also bundles 3 years of AWS Individual Membership, which is worth calculating against the member price before you decide whether to join AWS separately first. For the full cost breakdown, including how these fees compare to retake costs, see CAWI Certification Cost 2026.
Key Takeaway
Run the math before registering: joining AWS as a member first may cost less overall than paying the nonmember rate, even after accounting for membership dues, depending on your situation.
Codebook and Reference Requirements
Part C tests code application using AWS D1.1 structural steel - this isn't a standalone CWI endorsement, it's baked directly into the initial CAWI exam line as Domain 3. Current published guidance targets D1.1:2025, though the Exam References and Editions Guide also permits D1.1:2020, and AWS provides both editions digitally. Printed bound references are allowed at the test site, but digital word search is disabled on the electronic version - so if you're relying on a digital codebook, you need to know it well enough to navigate by section number and tab structure, not by keyword search.
Match the codebook edition to your appointment's specific reference instructions. Because two editions are currently permitted, showing up with the wrong one - or an unauthorized personal copy with extra annotations - can create problems at check-in. Confirm the required edition when you schedule, not the week before your test date.
Why Part B Comes First
AWS's guidance is to take Part B before Parts A and C. Part B is the hands-on, paper-based practical exam administered at AWS-authorized sites using supplied specifications, weld replicas, and inspection tools - it's logistically different from the computer-based Parts A and C at Prometric, and scheduling it separately (and earlier) gives you room to retake it if needed without derailing your Prometric appointments. It also reinforces fundamentals you'll need for Part A's terminology-heavy content and Part C's fabrication/inspection code application.
This sequencing decision is one of the most CAWI-specific pieces of exam strategy there is - it has nothing to do with generic test-taking advice and everything to do with how AWS structures the three-part exam line logistically. For more on how the three parts differ in question style and cognitive demand, read How Hard Is the CAWI Exam?
What Happens After You Qualify and Certify
CAWI status is intentionally temporary: it lasts no more than 3 years, cannot be renewed or recertified, and requires you to work under the supervision of a CWI or SCWI the entire time you hold it. This is a defining structural feature of the credential - CAWI is a bridge, not an endpoint. Upgrading to full CWI status requires meeting the applicable experience and examination criteria for CWI at that time; simply waiting out your 3-year CAWI window does not convert you automatically.
Understanding this timeline matters when you're weighing whether to pursue CAWI at all. If you're not sure the investment makes sense for your career stage, Is the CAWI Certification Worth It? walks through the tradeoffs, and CAWI Salary Guide 2026 covers what the role typically pays while you're building toward CWI eligibility.
Mapping Eligibility to a Prep Timeline
Once you've confirmed which of the five routes you qualify under and gathered your documentation, the real work is preparing for three separately scored parts with very different formats: closed-book recall (Part A), hands-on tool use (Part B), and open-book code lookup (Part C). A simple way to sequence study time is to front-load the domain that takes longest to build fluency in, then finish with the domain closest to test day.
Part B Practical Foundations
- Learn weld flaw identification and Procedure/Welder Qualification requirements, since these two subtopics alone carry a 62% minimum weight in Part B.
- Practice with actual gauges and replicas if you have shop access, since Part B is hands-on, not multiple choice.
Part A Fundamentals
- Drill terminology, welding processes, and symbols - together over a third of Part A's minimum allocation.
- Layer in NDE test methods and welding-related calculations once terminology is solid.
Part C Code Book
- Practice open-book navigation of your confirmed D1.1 edition - timed, since word search is disabled digitally.
- Focus on Qualification, Fabrication, and Inspection, which together carry a 75% minimum weight.
This is a starting framework, not a rigid formula - actual pacing depends on your existing field experience. For a deeper, domain-by-domain study plan, see CAWI Study Guide 2026, and for a quick pre-exam refresher, bookmark CAWI Cheat Sheet 2026. Practicing with realistic questions on our CAWI practice test platform before each Prometric or on-site appointment helps you gauge whether you're actually above the 60% threshold per part, not just on average.
Frequently Asked Questions
No. AWS does not mandate initial preparation training as a prerequisite for CAWI. You need documented education, qualifying work experience matching one of the five eligibility routes, and a recent vision examination.
A high school diploma or equivalent plus 2 years of qualifying experience is the shortest documented path. Candidates with 2 years of qualifying postsecondary study need only 6 months of experience, which can be faster depending on your schooling background.
No. Each of the three parts - Part A, Part B, and Part C - must independently reach at least 60%. There is no averaging across parts, so a strong Part A score cannot offset a failing Part B or Part C score.
Current guidance targets D1.1:2025, but D1.1:2020 is also permitted under the Exam References and Editions Guide. Confirm which edition your specific appointment requires before test day, since both are currently allowed.
Yes, it expires after a maximum of 3 years and cannot be renewed or recertified. Upgrading to CWI requires separately meeting CWI's applicable experience and examination criteria before that window closes.
