- CEG means Certified in Engineering Graphics, a credential administered by ATMAE and aimed at students and early-career technologists.
- The current exam is open-book, 142 multiple-choice questions, with two hours allowed; only printed references are 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, fasteners, and gears, sheet metal, and welding.
CEG Defined: What the Credential Actually Is
CEG stands for Certified in Engineering Graphics. It is a certification that verifies a candidate understands the language of technical drawings: how parts and assemblies are represented, dimensioned, toleranced, and annotated according to recognized drafting standards. It tests knowledge of engineering graphics practice, not your speed in any one software package.
If you have arrived here from a search for the acronym, note that several unrelated credentials in other industries share the same three letters. This article, and everything on this site, concerns only Certified in Engineering Graphics. For shorter definitions of the term, see our pages on what CEG stands for and CEG meaning.
In practical terms, CEG is a third-party signal that a graduate or early-career technologist can read a drawing and interpret its intent correctly. That includes the unglamorous but essential details: which line type means hidden geometry, what a title block must contain, how a tolerance stack-up is calculated, and what a feature control frame is telling a machinist.
Who Runs It and Who Can Sit for It
The administering body
The credential is administered by the Association of Technology, Management, and Applied Engineering (ATMAE). ATMAE's study guide describes online delivery with an approved proctor, so you test remotely under supervision rather than at a dedicated testing center.
Eligibility routes
CEG is built around students and recent graduates in technical programs. Eligibility includes any of the following:
- 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
- An ATMAE-approved equivalency
Because eligibility details and registration steps can change, confirm them against the issuer's current pages before you commit. Our CEG requirements guide walks through eligibility and prerequisites in more depth.
A note on senior status
ATMAE also offers a separate senior credential, CSEG, with its own requirements. Do not confuse the two: the continuing-education expectations that apply to senior certification do not apply to the initial CEG. Initial CEG status continues with annual dues and does not require continuing education.
How the Exam Works
Format at a glance

|---|---|
| Question count | 142 multiple-choice questions (current credential page) |
| Time allowed | Two hours (current certification FAQ) |
| Book policy | Open-book; printed reference materials permitted |
| Prohibited resources | Internet resources and software-based references |
| Delivery | Online with an approved proctor |

Reading the passing standard correctly
The passing requirement is expressed as a cumulative score of 70 points or higher, which is not the same as scoring 70 percent. Treat that distinction seriously when you plan your preparation, and see our dedicated page on the CEG passing score for what is and is not known about how the points work.
Open-book does not mean easy
With 142 questions in two hours, you have well under a minute per item on average. A printed reference can rescue you on a specific table or definition, but you cannot afford to look up every question. Candidates who rely on the book as a substitute for understanding tend to run out of time, while those who use it as a verification tool for a handful of items do far better. Our breakdown of how hard the CEG exam is explores this tradeoff.
A note on question-count discrepancies
Older versions of ATMAE's study guide describe slightly different question counts, and the guide's own content-area allocations do not agree with its prose. Rely on the current credential page and certification FAQ for the live format, and treat any older numbers you find elsewhere as legacy information. Our exam dates and scheduling guide covers how to confirm current logistics.
The 16 Content Areas You Are Tested On
ATMAE's study guide organizes the exam into 16 official major content areas. These are the exam objectives themselves, and they are the best map of what to learn. The issuer does not publish percentage weights for these areas, so avoid any resource that claims precise domain weightings. For a deeper walk through each area, read our complete guide to all 16 CEG content areas.
Standards, sheets, and measurement
Domains 1-3: The Foundation
These areas establish the vocabulary and conventions every later topic depends on.
- ASME Standards, Terms, and Line Conventions: line types and their meanings, and standard terminology.
- ASME Standard Sheets, Title Blocks, Revision Blocks, and Part Lists: what belongs on a sheet and how revisions are tracked.
- Units, Measuring Devices, Scaling Issues, and Metric/Inch Conversion: choosing scales, reading instruments, and converting between unit systems without error.
Geometry and views
Domains 4-8: Seeing and Representing Shape
This cluster tests spatial reasoning and the standard ways of showing a part.
- Geometry Terms, Definitions, and Constructions (2D and 3D): geometric vocabulary and construction logic.
- Orthographic Projection Theory, Standard Representation, and Spatial Visualization: projecting views and mentally rotating objects.
- Sectional View Standards, Terms, and Conventional Practices: cutting planes, hatching, and conventions such as when features are not sectioned.
- Auxiliary View Standards, Terms, and Conventional Practices: showing true shape of inclined surfaces.
- Pictorial Drawings and 3D Modeling Representation Methods: isometric and other pictorial approaches, and how 3D models are represented.
Assemblies, dimensions, and tolerances
Domains 9-12: Communicating Requirements
Here the exam shifts from showing shape to specifying what must be built and inspected.
- Assembly Drawing Methods: how components are shown together and identified.
- Dimensioning Standards, Including Choice and Placement Methods: which dimensions to give and where to place them.
- Tolerancing Calculations and Practices: limits, fits, and the arithmetic of tolerance.
- Geometric Dimensioning and Tolerancing (GDT): symbols, feature control frames, and datums.
Manufacturing detail and specialized topics
Domains 13-16: Production-Facing Knowledge
The final cluster covers the notations that connect a drawing to the shop floor.
- Machining Specifications, Callouts, and Surface Texture Symbols: reading hole callouts and surface finish notation.
- Screw Thread Representation: how threads are drawn and noted.
- Springs and Fasteners: conventional representation of springs, bolts, screws, and related hardware.
- Specialized Examples (gears, sheet metal, welding, castings, plastics, etc.): process-specific drawing conventions.
Key Takeaway
Do not over-invest in the glamorous topics at the expense of the foundation. Domains 1 through 3 supply the vocabulary used in every other area, and a weak grasp of line conventions, title block content, or unit conversion will cost you points scattered across the entire exam.
What CEG Is Not
Clarity about scope saves you from studying the wrong material.
- It is not a CAD software test. CEG assesses engineering graphics knowledge, not proficiency in a particular CAD package or a timed modeling task.
- It is not a continuing-education credential at the initial level. Initial CEG status continues with annual dues and has no continuing-education requirement.
- It is not the same as other credentials sharing the acronym. Fees, domains, and administering bodies from unrelated certifications do not apply here.
- It is not defined by published percentage weights. The official content areas are listed, but no domain percentages are published.
Also be aware that the study guide names specific standards editions. Check the guide itself rather than assuming the newest edition of a standard is the one the exam references. Our CEG study guide and one-page cheat sheet are organized around the official content areas for this reason.
Fees, Dues, and Retakes
CEG pricing depends on your status and registration route. For individuals, the fee includes applicable membership and certification upon passing.
| Individual Route | Exam Fee (USD) |
|---|---|
| Student member | $25 |
| Student non-member | $50 |
| Professional member | $50 |
| Professional non-member | $150 |
Institutional options
- Institutional assessment-only testing: $25 per student, which does not itself include membership or certification.
- Group certification testing: $75 per student.
Retakes and annual dues
Retakes cost $25 per attempt, and under the current FAQ there is no waiting period. Once certified, annual dues apply:
- Students: $25 membership plus $25 per certification
- Professionals: $100 membership plus $35 per certification
Fee schedules are updated periodically, so verify against the issuer's current fee page before paying. For a full breakdown and budgeting advice, see our CEG certification cost guide.
Who Values It and Where It Fits
CEG is positioned as an entry-level credential for people moving from technical programs into industry. The skills it validates are relevant wherever drawings drive production: manufacturing and machining operations, product design and drafting teams, quality and inspection roles, and technical support functions that must interpret engineering documents. Graduates of technology and engineering technology programs are the natural audience.
The credential does not guarantee a job or a specific pay level, and this site does not publish salary figures for it. What it does is give a recent graduate something concrete and externally verified to place alongside a degree and coursework, which can help when a hiring manager is comparing candidates with similar transcripts. If you are weighing the investment, our ROI analysis, salary discussion, and CEG jobs overview approach the question from different angles.
Sequencing Your Preparation by Domain
Because the exam is open-book and time-pressured, the goal is to build fluency in the areas you cannot afford to look up, and organization in the areas you can. Here is one way to sequence the 16 content areas over a few weeks. Adjust the pacing to your background.
Foundation Vocabulary
- Domains 1-3: line conventions, sheet layout, title and revision blocks, units and conversion
- Build the first tabs in your printed reference
Views and Spatial Reasoning
- Domains 4-8: geometry, orthographic, sectional, auxiliary, and pictorial representation
- Practice visualization problems, since these cannot be looked up
Specification Topics
- Domains 9-12: assemblies, dimensioning, tolerance calculations, and GD&T
- Work calculation problems by hand to speed up under time pressure
Shop-Floor Detail and Timed Practice
- Domains 13-16: machining callouts, surface texture, threads, springs, fasteners, and specialized processes
- Take timed mixed sets against a two-hour pace
Schedule tolerancing and GD&T earlier rather than later if they are new to you, since they combine symbols, rules, and arithmetic and reward repetition. Finish with timed sets drawn from all 16 areas so you can feel how long lookups really take. When you are ready to test yourself, try the practice questions on the main CEG practice test site, and see our CEG training resources for additional ways to build skills. You can also review reported outcomes in our pass rate discussion to set realistic expectations.
Key Takeaway
Use the open-book allowance to protect yourself from forgotten details, not to replace study. If you find yourself needing the book for most questions in a practice set, that domain needs more learning time, not a bigger index.
