How the 11-Domain Blueprint Works
The Certified Welding Supervisor credential from the American Welding Society (AWS) is built on 11 formal examination objectives. These headings and weights come from the current Examination User Guide (footer version 05.06.2026) and are corroborated by AWS QC13:2006, the specification for certifying welding supervisors. They describe what the exam measures, not how a training course is organized, so a prep program may group the material differently.
Two structural facts matter immediately. First, Domains 1 through 10 correspond to Part A, Fundamentals of Welding Supervision, while Domain 11 corresponds to Part B, Welding Practices & Economics. Second, QC13 describes the weights as approximate percentages. They total 100% across the published table, but they have not been recalculated within each part, and no one should convert them into an exact count of questions per domain. Treat the weights as a guide to emphasis, not a promise about any single exam form.
Domain Weights at a Glance
| Domain | Name | Weight | Exam Part |
|---|---|---|---|
| 1 | Knowledge of Welding Supervision | 5% | Part A |
| 2 | Understanding of Drawings and Specifications | 10% | Part A |
| 3 | Knowledge of Base Material and Welding Materials | 5% | Part A |
| 4 | Familiarity with Welding, Brazing, Cutting, Equipment, Theory and Application | 5% | Part A |
| 5 | Knowledge of Safety Requirements | 10% | Part A |
| 6 | Welding Instructions | 10% | Part A |
| 7 | Knowledge of Welding Practices and Production Controls | 10% | Part A |
| 8 | Welding Inspection | 5% | Part A |
| 9 | Work Reports and Records | 5% | Part A |
| 10 | Understanding the General Applications of Welding Standards | 5% | Part A |
| 11 | Productivity and Performance | 30% | Part B |
The pattern is easy to read. Productivity and Performance alone carries 30%, which is more than any two other domains combined. Four domains (Drawings and Specifications, Safety, Welding Instructions, and Practices and Production Controls) carry 10% each, and the remaining six carry 5% each. If you want a quick-reference companion while you read, the CWS Cheat Sheet condenses the must-know facts onto one page.
Part A: Domains 1 Through 10
Part A is titled Fundamentals of Welding Supervision and contains 150 questions across the ten domains below. Part A tests breadth: the supervisor's role, reading the paperwork, understanding materials and processes, running a safe shop, instructing welders, controlling production, inspecting, documenting, and applying standards.
The Foundation Domains (1, 3, 4)
Domain 1: Knowledge of Welding Supervision (5%)
This domain covers the supervisor's role itself. Candidates should be comfortable with what a welding supervisor is responsible for and how that responsibility connects to the people, procedures and quality outcomes on the floor.
- Responsibilities and authority of the supervisory position
- How supervisory duties connect to welders, inspectors and management
- The relationship between supervision and the qualification and certification framework
Domain 3: Knowledge of Base Material and Welding Materials (5%)
Supervisors do not need to be metallurgists, but they must understand how base metals and filler or consumable materials behave and why the wrong choice causes problems.
- Common base metal categories and their weldability concerns
- Welding consumables, their selection and their handling
- How material issues surface as defects or procedure problems
Domain 4: Familiarity with Welding, Brazing, Cutting, Equipment, Theory and Application (5%)
This is the process-and-equipment knowledge domain. The emphasis on "familiarity" in the title signals breadth over deep engineering design.
- Principal welding, brazing and cutting processes and where each is applied
- Equipment used with those processes
- Basic theory behind how the processes work
The Paperwork and Standards Domains (2, 9, 10)
Domain 2: Understanding of Drawings and Specifications (10%)
A supervisor translates engineering intent into shop action. At 10% this is one of the higher-weighted Part A areas, and it rewards candidates who can read a drawing quickly and accurately.
- Reading and interpreting welding symbols and drawing details
- Understanding contract and project specifications
- Recognizing when a drawing and a specification conflict or are incomplete
Domain 9: Work Reports and Records (5%)
Documentation is part of supervisory accountability. Expect questions about what must be recorded and why those records matter later.
- Work reports and production records
- Maintaining documentation that supports quality and traceability
- How records support audits, disputes and continuous improvement
Domain 10: Understanding the General Applications of Welding Standards (5%)
This domain is about knowing how standards and codes are used, not memorizing every clause. Because the exam is open-book, the practical skill is navigating references efficiently.
- How codes, standards and specifications apply to different kinds of work
- Identifying which governing document controls a given situation
- Locating needed information quickly in your permitted references
The Shop-Floor Domains (5, 6, 7, 8)
Domain 5: Knowledge of Safety Requirements (10%)
Safety is weighted at 10%, and it is a domain where AWS's reference lists matter: the Examination User Guide lists ANSI Z49.1:2005, while the AWS program webpage lists ANSI Z49.1:2012. Verify the approved edition when you schedule.
- Welding and cutting safety practices and hazard recognition
- Protective equipment and safe work environment expectations
- The supervisor's duty to enforce safe practice
Domain 6: Welding Instructions (10%)
This domain concerns the instructions that govern how welding is done and how a supervisor communicates them to welders.
- Understanding and applying written welding instructions
- Making sure welders have, understand and follow the correct instructions
- Connecting instructions to qualification and procedure requirements
Domain 7: Knowledge of Welding Practices and Production Controls (10%)
Where Domain 6 covers instructions, Domain 7 covers the practices and controls that keep production consistent and compliant.
- Good welding practice during fabrication
- Production controls that keep work within requirements
- Recognizing and correcting departures from required practice
Domain 8: Welding Inspection (5%)
Supervisors work alongside inspectors and must understand inspection well enough to prevent rejects and respond appropriately when they occur.
- Inspection concepts relevant to supervisors
- How inspection results feed back into production decisions
- The supervisor's role relative to the inspector's role
Key Takeaway
The four 10% domains (Drawings and Specifications, Safety, Welding Instructions, and Practices and Production Controls) form the practical core of Part A. Master them first, then use the 5% domains to broaden your coverage. For a realistic sense of how much preparation to budget, read How Hard Is the CWS Exam?
Part B: Productivity and Performance (30%)
Domain 11, Productivity and Performance, is the entire content of Part B, Welding Practices & Economics, and it is the single largest category in the blueprint at 30%. That weighting says something important about how AWS views the credential: a certified welding supervisor is not only a technician who knows the rules, but a manager who understands the economics of getting welded product out the door.
Domain 11: Productivity and Performance (30%)
Expect scenario-style thinking about cost, efficiency and output. Because the exam is open-book, the challenge is rarely recalling a formula from memory; it is knowing which relationship applies and executing it correctly under time pressure.
- Welding economics: how process choices, deposition and labor affect cost
- Productivity: improving output without sacrificing quality or safety
- Performance: measuring and managing results on the floor
- Calculations, which is why calculator rules (below) matter
Because Part B is a separate sitting with its own 2-hour limit and 70% minimum, a weak Part B result is a distinct hurdle even if Part A goes well. For a data-oriented look at outcomes, see CWS Pass Rate: What the Data Shows, and for the scoring threshold itself see CWS Passing Score: Exactly What You Need to Pass.
Exam Format, Open-Book Rules and Logistics
Both parts are computer-based, open-book examinations delivered at Prometric test centers with four-option multiple-choice questions. Each part allows 2 hours of examination time, with a scheduled seat time of 2.5 hours per part, and requires at least 70% to pass. Total examination time is 4 hours across the two parts. Part A has 150 questions.
Reference Rules
- Permitted references must be original and either permanently bound or securely fastened through all pages. Loose sheets are prohibited.
- Digital references are supplied at the test center, with the exception of the AWS Welding Handbook series.
- Approved calculators include four-function, construction and nonprogrammable scientific models.
- The current examination guide requests visual-acuity documentation.
- Reference editions matter. The ANSI Z49.1 discrepancy (2005 vs. 2012) is the known example, so confirm approved editions against AWS's Exam References and Editions Guide when you schedule.
Fees and Eligibility That Shape Your Timeline
Your study plan should account for cost and eligibility, because both affect when you can sit and how many attempts are practical.
2026 Fee Structure
| Item | Member | Nonmember |

Eligibility
- A high-school diploma or approved equivalent.
- Three years of qualifying practical welding experience involving weldments fabricated to codes, specifications or other standards.
- Three years of documented relevant teaching may substitute for one year of practical experience.
- Two years of welding-supervision experience is preferred, not required.
- Formal preparation training is optional.
Details on documentation and qualification paths are in CWS Requirements: Eligibility, Prerequisites and How to Qualify.
Validity and Renewal
Certification is valid for three years, with renewals at years 3 and 6 based on documented continued welding-supervisor activity. Ninth-year recertification requires continued-activity documentation plus either passing both exam parts or earning 80 PDHs over nine years, including at least 20 in the final three years.
Sequencing the Domains in Your Preparation
Method matters less than sequencing here. The 30/70 split between Part B and Part A suggests giving Domain 11 its own dedicated block while front-loading the 10% domains in Part A. The timeline below is one reasonable arrangement, and you can compress or expand it around your own schedule. For a fuller plan, the CWS Study Guide walks through a first-attempt strategy.
Orientation and Foundations
- Domain 1 (supervision role) and Domain 3 (materials)
- Tab your permitted references as you go
Paperwork Fluency
- Domain 2 (drawings and specifications)
- Domain 10 (applications of standards) and Domain 9 (records)
Shop-Floor Core
- Domain 5 (safety), Domain 6 (instructions), Domain 7 (practices and controls)
- Domain 4 (processes and equipment) and Domain 8 (inspection)
Economics and Calculations
- Domain 11 in depth, with calculator practice using an approved model
- Timed Part A and Part B practice runs
Practice questions that mirror the four-option, timed format are the most efficient way to test this sequence. The CWS practice tests let you drill by content area so you can see which domains need more time before you pay for an attempt.
Where the Credential Gets Used
Welding supervisors are needed wherever fabricated weldments must meet codes and specifications. That includes fabrication shops, structural and pressure-related manufacturing, and construction and contracting operations, where a supervisor is accountable for qualified procedures, safe practice, inspection readiness and cost. The Productivity and Performance emphasis suggests the credential is aimed at people expected to manage output as well as quality. For role-level detail, see CWS Jobs, and for earnings context see the CWS Salary Guide and the ROI analysis.
Key Takeaway
Prepare for the exam the way a supervisor works: know the rules, but be fast at finding them and strong on the economics. If you want to check your readiness across all 11 areas, start with a timed set at the main practice test site.
Frequently Asked Questions
The published blueprint has 11 domains. Domains 1 through 10 correspond to Part A (Fundamentals of Welding Supervision), and Domain 11, Productivity and Performance, corresponds to Part B (Welding Practices & Economics).
Productivity and Performance, at 30%. The next highest weights are 10% each for Drawings and Specifications, Safety Requirements, Welding Instructions, and Welding Practices and Production Controls.
No. QC13 describes the weights as approximate percentages, and they have not been converted into per-domain question allocations. Use them to prioritize emphasis, not to predict exact counts.
AWS documents conflict. The Examination User Guide lists 60 items on one page and 30 on another, and QC13 clause 6.1.2 specifies 30. Confirm against the current guide and plan your pacing conservatively. Part A has 150 questions.
Yes, but with rules. References must be original and permanently bound or securely fastened through all pages, loose sheets are prohibited, and digital references are supplied except for the AWS Welding Handbook series. Each part still has a 2-hour limit and a 70% minimum, so quick navigation of your references matters. See the What Is CWS? overview for background on the credential.
