- CEG means Certified in Engineering Graphics, an ATMAE credential that tests drafting and graphics knowledge, not software button-clicking.
- The current exam is open-book, 142 multiple-choice questions, with two hours allowed and printed references permitted.
- Passing requires a cumulative score of 70 points or higher, not 70 percent.
- Sixteen official content areas run from ASME line conventions through GD&T, threads, springs, and specialized parts.
What a CEG Actually Is
When people ask "what is a CEG?", the answer on this site is specific: CEG stands for Certified in Engineering Graphics. It is a certification that verifies a candidate understands the language of technical drawings: how parts are shown, dimensioned, toleranced, annotated, and assembled according to recognized drafting standards.
The acronym is shared by other, unrelated credentials in other industries. Everything on this page concerns only the engineering graphics certification. If you landed here searching for a different CEG, the details below (the exam, the fees, the content areas) will not apply to you. For related phrasing of the same question, see our explainers on what CEG stands for and the meaning of CEG.
A CEG is best understood as a knowledge credential. It shows that you can read and reason about engineering drawings correctly. It is not a CAD operator test, and it does not ask you to model a part in a particular software package. The questions probe whether you know the conventions: what a line type means, how a section view is constructed, what a feature control frame is telling a machinist.
Who Runs It and What It Measures
The credential is administered by the Association of Technology, Management, and Applied Engineering (ATMAE). ATMAE publishes a study guide for the exam, and that guide's content section supplies the 16 official major content areas that define the scope. Those areas are exam objectives published by the certifying body, not categories invented by prep providers.
Delivery is online with an approved proctor, per the study guide's description. That matters for logistics: you are not driving to a testing center, but you do need to arrange a proctor who meets ATMAE's requirements. For the broader picture of how the credential is positioned, see our CEG certification overview and What Is CEG Certification?.
The Exam Format in Plain Terms
The current credential page describes a multiple-choice exam of 142 questions, and the certification FAQ allows two hours. The exam is open-book, and printed reference materials are permitted. Internet resources and software-based references are prohibited.
One source conflict is worth knowing about. The older study guide prose describes 145 questions in two hours, and the question allocations listed in its content-area section add up to 160. Those figures are legacy inconsistencies in the guide, not the current exam length. Use 142 questions as the current figure, and do not try to convert the guide's allocations into domain weights. ATMAE does not publish percentage weights, so any site that gives you a precise percentage per domain is guessing.
| Exam Feature | Current Detail |
|---|---|
| Format | Multiple choice |
| Number of questions | 142 |
| Time allowed | Two hours |
| Book policy | Open-book; printed references allowed |
| Prohibited aids | Internet resources and software-based references |
| Passing standard | Cumulative score of 70 points or higher |
| Delivery | Online with an approved proctor |
What "Open-Book" Really Means for Pacing
Open-book sounds easier than it is. With 142 questions in two hours, you have under a minute a question on average. There is no time to learn a topic from your references during the exam. The books help you confirm a table value, a thread designation format, or a symbol definition, but only if you already know where to look. Candidates who treat open-book as a license to skip preparation tend to run out of time flipping pages.
The passing standard is a cumulative score of 70 points or higher, which is not the same as 70 percent. Read our CEG passing score guide for how to think about that distinction, and see how hard the CEG exam is for a realistic view of difficulty. For what is known about outcomes, the CEG pass rate article explains why we do not quote a number.
The 16 Content Areas Behind the Credential
The scope of a CEG is defined by 16 major content areas. Here they are, with what each one demands in practice. For a deeper walk-through of each, see the complete guide to all 16 CEG content areas.
Drawing Standards and Conventions (Domains 1 to 3)
Domain 1: ASME Standards, Terms, and Line Conventions
The foundation. You need fluency in what each line type communicates and the standard vocabulary of the drafting world.
- Visible, hidden, center, cutting-plane, and section lines
- Line weight and precedence when lines coincide
- Standard terminology used in drawing practice
Domain 2: ASME Standard Sheets, Title Blocks, Revision Blocks, and Part Lists
Drawings are documents, and documents have structure. Expect questions on what belongs where on a sheet.
- Standard sheet sizes and layout
- Title block and revision block content
- Parts lists and how items are identified
Domain 3: Units, Measuring Devices, Scaling Issues, and Metric/Inch Conversion
Calculation-heavy and unforgiving of sloppy arithmetic. Because the exam is open-book, conversion factors can be looked up, but scale reasoning must be second nature.
- Metric and inch conversion
- Drawing scale interpretation
- Selecting and reading measuring devices
Geometry and Views (Domains 4 to 7)
Domain 4 covers geometry terms, definitions, and constructions in 2D and 3D. Domain 5 covers orthographic projection theory, standard representation, and spatial visualization, which is the skill of mentally rotating an object and predicting its views. Domain 6 covers sectional view standards, terms, and conventional practices, and Domain 7 covers auxiliary view standards, terms, and conventional practices. These four areas reward candidates who can sketch quickly; if you can draw the missing view on scratch paper, most of the multiple-choice options become obvious.
Representation, Assembly, and Dimensioning (Domains 8 to 10)
Domain 8 addresses pictorial drawings and 3D modeling representation methods. Domain 9 addresses assembly drawing methods. Domain 10 addresses dimensioning standards, including choice and placement methods. Dimensioning is a classic source of missed questions because the right answer depends on a convention (placement, avoidance of redundancy, reference dimensions) rather than on intuition.
Tolerancing and Manufacturing Callouts (Domains 11 to 13)
Domain 11: Tolerancing Calculations and Practices
Math meets drawing. You will work with limits, fits, and stack-up style reasoning.
- Limit dimensions and tolerance accumulation
- Fit relationships between mating parts
- Choosing appropriate tolerance practices
Domain 12: Geometric Dimensioning and Tolerancing (GDT)
Often the area candidates find most demanding. You need to read feature control frames and understand what each symbol controls.
- Datums and datum reference frames
- Form, orientation, location, and runout controls
- Material condition modifiers and what they permit
Domain 13 covers machining specifications, callouts, and surface texture symbols. This is where drawing meets the shop floor: holes, counterbores, countersinks, and the notation that tells a machinist how a surface should be finished.
Fasteners and Specialized Features (Domains 14 to 16)
Domain 14 covers screw thread representation, including how threads are drawn and noted. Domain 15 covers springs and fasteners. Domain 16 is the catch-all for specialized examples: gears, sheet metal, welding, castings, plastics, and similar topics. Because Domain 16 is broad, candidates often underprepare for it. A little exposure to each specialty (weld symbols, bend allowances, draft on castings, gear terminology) goes a long way.
Who Can Sit for the Exam
CEG is built with students and early-career technologists in mind. Eligibility includes:
- The last year of an eligible four-year technical, technology, technology-management, or engineering-related BA/BS program
- The second year of an eligible two-year AA/AS/AAS program
- ATMAE-approved equivalency
That equivalency pathway matters for working drafters and designers who built their expertise on the job rather than in a classroom. Details and edge cases are covered in our CEG requirements article. Always confirm your program's eligibility with ATMAE before registering, since "eligible" depends on the program type.
Fees, Retakes, and Annual Dues
CEG pricing depends on who you are and how you register. The structure is more nuanced than a single sticker price, so it helps to separate the routes.
Individual Exam Fees
| Candidate Type | Exam Fee (USD) |
|---|---|
| Student member | $25 |
| Student non-member | $50 |
| Professional member | $50 |
| Professional non-member | $150 |
These individual routes include applicable membership and certification upon passing.
Institutional Routes and Retakes
- Institutional assessment-only testing: $25 per student. This route does not itself include membership or certification.
- Group certification testing: $75 per student.
- Retakes: $25 per attempt, with no waiting period under the current FAQ.
Annual Dues After You Pass
Initial CEG status continues with annual dues and does not require continuing education. Student dues are $25 for membership plus $25 per certification. Professional dues are $100 for membership plus $35 per certification. For a full cost walk-through, including how to choose between routes, read the CEG certification cost breakdown.
CEG Versus CSEG
ATMAE also offers a separate senior credential called CSEG. It is a different certification with its own requirements, including a professional development unit requirement on a multi-year cycle. Those CSEG requirements do not apply to CEG. If you hold or pursue CEG, you do not need to track PDUs for that credential.
| Aspect | CEG | CSEG |
|---|---|---|
| Level | Initial credential | Separate senior credential |
| Continuing education | Not required for initial status | Has its own PDU-based renewal requirements |
| Ongoing cost | Annual dues | Governed by ATMAE senior-status policy |
For the specifics of senior status, go to ATMAE's senior certification page rather than relying on secondary summaries.
Where a CEG Fits in the Job Market
A CEG signals that you can interpret and produce drawings to recognized standards. That is relevant anywhere engineering documentation drives production: manufacturing firms, machine shops, product design groups, tooling and fixture shops, and engineering departments that hand drawings to suppliers. Typical roles that draw on these skills include drafters, CAD technicians, design technologists, manufacturing technologists, and quality-oriented positions that read drawings daily.
Because the credential is student-friendly, it is most often used as a differentiator for graduates entering the field: a verified signal that you know GD&T, dimensioning, and drafting conventions beyond coursework. How much it moves the needle depends on the employer and region, and we do not quote salary numbers we cannot source. For the earnings discussion, see our CEG salary guide, the analysis of whether CEG is worth it, and our overview of CEG jobs.
Key Takeaway
Treat CEG as proof of drawing-standards literacy. On a resume, pair it with specific evidence: drawings you have produced, GD&T you have applied, or projects where you handed a print to a manufacturer.
A Domain-Ordered Prep Sequence
You do not need a generic study plan, but sequencing by domain does help, because later areas build on earlier ones. Here is one logical order for a six-week run, assuming you already have some drafting exposure.
Standards, Sheets, Units (Domains 1 to 3)
- Memorize line conventions and sheet block contents
- Drill metric/inch conversion and scale math
Geometry and Projection (Domains 4 and 5)
- Sketch missing views from partial orthographic sets
- Practice spatial visualization on irregular parts
Sections, Auxiliaries, Pictorials, Assemblies (Domains 6 to 9)
- Construct full, half, and offset sections
- Work auxiliary view problems on inclined surfaces
Dimensioning and Tolerancing (Domains 10 and 11)
- Apply placement rules to messy drawings
- Run limit and fit calculations until they feel routine
GD&T and Callouts (Domains 12 and 13)
- Decode feature control frames symbol by symbol
- Read machining notes and surface texture symbols
Threads, Fasteners, Specialties, and Review (Domains 14 to 16)
- Cover thread notes, springs, welds, castings, and sheet metal
- Take timed practice sets and tab your printed references
The reasoning: GD&T and tolerancing are easier once you can interpret views and dimensions fluently, and the specialty areas are best saved for last since each is a small slice. For a fuller plan, see the CEG study guide, and for last-minute review, the CEG cheat sheet. If you want structured coursework alongside, browse CEG training options.
Build Your Open-Book Kit
Since printed references are allowed, assemble them deliberately. Tab the thread tables, tolerance and fit charts, GD&T symbol summaries, and weld symbol references so you can find them in seconds. Then run timed sets on the CEG practice test to learn how long lookups actually take. Candidates who practice under the clock tend to discover which references are worth keeping on the desk and which just slow them down.
When you are ready to find out where you stand, take a full-length attempt on the CEG Exam Prep practice tests and use the results to decide which weeks of the plan above to repeat. Scheduling details are in our CEG exam dates article.
