What the Passing Score Actually Is
The Certified in Engineering Graphics (CEG) credential is administered by the Association of Technology, Management, and Applied Engineering (ATMAE). Its passing standard is stated plainly: a candidate must earn a cumulative score of 70 points or higher. That single sentence is the entire published cut line, and it is worth reading carefully, because the way candidates tend to interpret it is often slightly off.
If you are still deciding whether the credential fits your plans, the overview in What Is CEG Certification? covers the basics, and CEG Requirements 2026: Eligibility, Prerequisites & How to Qualify walks through who may sit for the exam. This article focuses narrowly on the scoring threshold and what it means for how you prepare and how you behave during the test.
Why "70 Points" Is Not "70%"
It is natural to see "70" and think "70 percent correct." The published standard does not say that. It says 70 points, cumulative. ATMAE does not publish a public conversion table explaining how raw responses translate into points, and this site will not invent one.
What does that mean for you in practical terms?
- Do not back-calculate a "number of questions I can miss." Any figure you derive from 142 questions multiplied by 70% is an assumption, not an ATMAE statement.
- Do not assume every question carries identical weight unless ATMAE says so. The public materials describe the standard as cumulative points; they do not break down per-question value.
- Aim well above the line. Because the exact scoring mechanics are not public, the safest strategy is to prepare as though every question matters and to leave margin.
If you have seen claims online about a specific pass percentage for this exam, treat them cautiously. Our breakdown in CEG Pass Rate 2026: What the Data Shows explains what can and cannot be said about outcomes, and How Hard Is the CEG Exam? Complete Difficulty Guide 2026 discusses perceived difficulty without fabricating statistics.
Format Facts That Shape Your Scoring Strategy
Your score is produced under specific conditions, and those conditions change how you should work. Here is what the current ATMAE sources establish:
| Element | Current specification |
|---|---|
| Administering body | ATMAE |
| Question type | Multiple choice |
| Number of questions | 142 (per the current credential page) |
| Time allowed | Two hours (per the current certification FAQ) |
| Open or closed book | Open-book |
| Delivery | Online with an approved proctor, per the linked study guide |
| Passing standard | Cumulative score of 70 points or higher |
Do the arithmetic on time: two hours is 120 minutes, and 142 questions leaves you well under a minute per item on average. That ratio is the single most important strategic fact on the page. An open-book exam sounds forgiving, but with fewer than 50 seconds of average working time per question, you cannot afford to look up every answer. The reference materials are a safety net for the questions where you genuinely need to confirm a value, not a substitute for knowing the material.
Key Takeaway
Because the pace is so tight, your goal is to answer the majority of questions from memory and spend your limited lookup time only on specific values, tables, and standard callouts you cannot reliably recall. Organize your printed references so any lookup takes seconds, not minutes.
Where Your Points Come From: The 16 Content Areas
The ATMAE study guide lists 16 major content areas. These are the official exam objectives, and every point you earn comes from them. The guide does not publish percentage weights for these areas, so we do not assign any here. What we can do is describe what each area asks of you and flag where candidates commonly need to slow down. For a deeper area-by-area treatment, see CEG Exam Domains 2026: Complete Guide to All 16 Content Areas.
Domains 1-3: Standards, Sheets, and Units
These foundational areas cover ASME standards, terms, and line conventions; ASME standard sheets, title blocks, revision blocks, and part lists; and units, measuring devices, scaling issues, and metric/inch conversion.
- Line types and what each one communicates on a drawing
- Standard sheet sizes and the information that belongs in title and revision blocks
- Scale ratios and reliable metric/inch conversions, where small arithmetic slips cost points
Domains 4-8: Geometry, Views, and Pictorials
These areas cover geometry terms and constructions in 2D and 3D; orthographic projection theory and spatial visualization; sectional views; auxiliary views; and pictorial drawings and 3D modeling representation methods.
- Recognizing the correct view arrangement from a described or pictured part
- Sectional view conventions, including what is and is not sectioned
- Auxiliary view logic for inclined surfaces, which rewards visualization practice
Domains 9-12: Assemblies, Dimensioning, Tolerancing, and GD&T
These cover assembly drawing methods, dimensioning standards (choice and placement), tolerancing calculations and practices, and geometric dimensioning and tolerancing.
- Dimension placement rules and avoiding redundant or conflicting dimensions
- Tolerance stack and limit calculations that must be worked accurately under time pressure
- GD&T symbols, feature control frames, and datum reference concepts
Domains 13-16: Machining, Threads, Fasteners, and Specialized Examples
These cover machining specifications, callouts, and surface texture symbols; screw thread representation; springs and fasteners; and specialized examples such as gears, sheet metal, welding, castings, and plastics.
- Reading hole and machining callouts correctly
- Thread notation and how threads are depicted
- Broad coverage of specialized topics, where breadth of familiarity matters
One more clarification: this exam tests engineering-graphics knowledge, not software-specific CAD performance. You are not being scored on your ability to operate a particular CAD package.
The 142 vs. 145 vs. 160 Question-Count Confusion
If you read the ATMAE study guide alongside the current credential page, you will notice that the numbers do not agree. This is a real source conflict, and it deserves a straight explanation rather than a quiet pick.
- The current credential page states a 142-question exam. This is the figure we use throughout this article.
- The study guide prose (linked revision 2.1.21, copyright 2014-2021) describes 145 questions in two hours.
- The guide's content-area question allocations add up to 160, which does not match either of the other two figures.
The practical takeaway is simple: do not build a prep plan around a precise per-domain question count. Prepare every one of the 16 areas, and confirm current details directly with ATMAE before test day. Our CEG Study Guide 2026: How to Pass on Your First Attempt is built around that same breadth-first approach.
Playing the Open-Book Rules Correctly
Open-book does not mean unrestricted. The rule is specific: printed reference materials are permitted, but Internet resources and software-based references are prohibited. That distinction should drive how you assemble your reference set.
What to bring in print
- A bound or well-organized set of notes covering standards, line conventions, and sheet/title block information
- Conversion tables and formulas for tolerancing calculations
- A GD&T symbol and feature control frame summary
- Machining callout, surface texture, and thread notation references
- Fastener and spring reference tables
What not to rely on
- Any website, search engine, or online document
- Any software-based reference, including electronic handbooks and apps
- Improvised lookups that you have not rehearsed
Because the exam is delivered online with an approved proctor, expect the testing environment to be monitored. Confirm the proctoring requirements and your allowed materials in advance so that nothing about your setup creates a problem on the day. A one-page distillation of the highest-value facts can help; see the CEG Cheat Sheet 2026: One-Page Review of Must-Know Facts for a model of how to compress material.
Key Takeaway
Index your printed references by the 16 content areas. When a question lands in, say, tolerancing or thread representation, you should know exactly which page to turn to without searching.
Fees, Retakes, and What a Failed Attempt Costs
The passing score has a financial side. Knowing what a miss costs helps you decide how much margin to build before you sit. The current individual exam fees (USD) are:
| Candidate category | Individual exam fee |
|---|---|
| Student member | $25 |
| Student non-member | $50 |
| Professional member | $50 |
| Professional non-member | $150 |
These individual routes include applicable membership and certification upon passing. Other routes exist: institutional assessment-only testing is $25 per student and does not itself include membership or certification, while group certification testing is $75 per student.
Retakes cost $25 per attempt, and the current FAQ lists no waiting period. That is a notably low barrier compared with many credentials, and it changes the risk calculation. Still, a low retake fee is not a reason to sit unprepared; each attempt consumes time and effort even when the fee is small. For the full pricing picture, including annual dues, see CEG Certification Cost 2026: Complete Pricing Breakdown. Fee details were last updated by ATMAE on May 21, 2026, so verify against the official fee page before you pay.
Eligibility and What Happens After You Pass
Who can sit
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
- ATMAE-approved equivalency
Check the details in CEG Requirements 2026: Eligibility, Prerequisites & How to Qualify before you register, so a passing score is not undermined by an eligibility problem.
Keeping the credential once you pass
Initial CEG status continues with annual dues and does not require continuing education. Annual student dues are $25 membership plus $25 per certification; professional dues are $100 membership plus $35 per certification. Do not confuse this with CSEG, a separate senior credential that carries its own, distinct renewal requirements. Those belong to CSEG, not to CEG.
If you are weighing the return on the credential, Is the CEG Certification Worth It? Complete ROI Analysis 2026 and CEG Salary Guide 2026: Complete Earnings Analysis discuss value qualitatively, and CEG Jobs looks at the roles where the credential tends to be relevant, including drafting, design, and technology-management positions.
A Domain-Ordered Prep Sequence
Because the cut score is cumulative and the exam is fast, the best plan is one that builds speed on calculation-heavy areas and recognition on convention-heavy ones. The sequence below is tied to the 16 content areas rather than generic study advice. Adjust the length to your own timeline.
Conventions and Units (Domains 1-3)
- Memorize line types, sheet and title block content, and revision/part list conventions
- Drill metric/inch conversions and scale calculations until they are automatic
Views and Visualization (Domains 4-8)
- Practice orthographic, sectional, and auxiliary view problems daily
- Review pictorial and 3D modeling representation methods
Dimensioning, Tolerancing, and GD&T (Domains 9-12)
- Work tolerance and limit calculations against a timer
- Build a GD&T symbol and feature control frame summary for your printed references
Callouts, Threads, Fasteners, Specialized Topics (Domains 13-16)
- Practice reading machining, surface texture, and thread callouts
- Skim gears, sheet metal, welding, castings, and plastics for broad familiarity, then run full timed practice sets
Why this order? Tolerancing and GD&T reward the most careful rehearsal, so they are scheduled once the visualization skills are in place, and the broad specialized topics come last because they reward familiarity more than deep calculation. For more structure, see CEG Training, and use the full-length timed sets on our CEG practice test site to rehearse the 142-question, two-hour pace. When you want to check how ready you are, take a timed practice exam and note which content areas cost you the most time.
Frequently Asked Questions
A cumulative score of 70 points or higher. ATMAE states the standard in points rather than as a percentage, so do not translate it into a fixed share of questions answered correctly.
The published standard says 70 points, not 70%. ATMAE does not publish a conversion between raw responses and points, so avoid calculating a number of allowable misses. Prepare to score comfortably above the line.
The current credential page specifies 142 multiple-choice questions, and the current certification FAQ allows two hours. Older study guide figures of 145 and a 160 allocation total conflict with the current page and should not be treated as the current exam length.
Printed reference materials are permitted. Internet resources and software-based references are prohibited. The exam is open-book but proctored, so confirm the allowed materials and testing setup in advance.
You can retake the exam. The retake fee is $25 per attempt, and the current FAQ lists no waiting period. Review the content areas that slowed you down before you try again, and check the ATMAE FAQ for the latest retake policy.
