CDT Exam Overview at a Glance
This is the condensed version of everything you need loaded into working memory before test day. It is not a substitute for deep preparation - for that, pair this page with the full CDT Study Guide 2026: How to Pass on Your First Attempt - but it is exactly what you should be scanning in the final 48 hours before you sit down at a FastTest workstation.
The Certified Dental Technician credential is administered by the National Board for Certification in Dental Laboratory Technology, an independent board affiliated with the National Association of Dental Laboratories. Candidates complete three separate exams: a Written Comprehensive exam, a Written Specialty exam, and a hands-on Practical exam. All three must be passed in the same specialty within a four-year window, so timing your registrations matters as much as your studying.
All 7 Domains Ranked by Weight
Everything on the Written Comprehensive exam falls into one of seven domains. Memorize the order below - it tells you exactly where to spend marginal study hours. For a deeper breakdown of each area, see the CDT Exam Domains 2026: Complete Guide to All 7 Content Areas.
| Domain | Weight |
|---|---|
| 5. Dental Laboratory Materials | 34-36% |
| 2. Anatomy | 17-19% |
| 7. Safe Working Practices | 12-14% |
| 6. Impressions and Models | 10-12% |
| 1. Industry Regulations and Scope of Practice | 8-10% |
| 3. Terminology and Principles | 6-8% |
| 4. Articulation | 6-8% |
Notice that Domains 5 and 2 alone account for roughly half the scored questions. If your review time is limited, weighting your effort in that order - materials first, anatomy second - mirrors how the exam is actually built. If you're still deciding whether the exam matches your background, How Hard Is the CDT Exam? Complete Difficulty Guide 2026 walks through realistic difficulty expectations by domain.
Fees, Fast Facts, and Registration Mechanics
Print this section out. These are the numbers candidates most often misremember or misjudge when budgeting and scheduling.
Exam Structure Fast Facts
- Written Comprehensive: 160 scored + 10 unscored field-test multiple-choice questions, 2 hours 45 minutes, $275.
- Written Specialty: 80 scored + 10 unscored field-test multiple-choice questions, 1 hour 30 minutes, $275.
- Practical: Performance-based, 5 hours 15 minutes, $650.
- Total cost across all three exams: $1,200.
- Time limit to pass all three in one specialty: 4 years.
Those unscored field-test items on both written exams are worth knowing about specifically because they look identical to scored questions - don't waste mental energy trying to guess which ones don't count. Just answer every question as if it matters, because most of them do.
Key Takeaway
Budget the full $1,200 and the four-year window into your planning from day one - a full cost breakdown by exam and specialty is available in CDT Certification Cost 2026: Complete Pricing Breakdown.
Eligibility is standardized regardless of specialty: a high-school diploma or equivalent, ethical and legal standing, English proficiency, and five years of dental-laboratory training or experience. Alternate education paths and a Recognized Graduate pathway exist for candidates who don't fit the standard five-year track - these are detailed in the current candidate handbook, revised March 1, 2026, and summarized in CDT Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Domain 5: The Materials Core You Cannot Skip
Because Domain 5 - "Identify the types, processes, physical properties and handling characteristics of dental lab materials (e.g., Traditional or Digital)" - makes up over a third of the Comprehensive exam, it deserves its own section on any cheat sheet worth using.
Domain 5: Dental Laboratory Materials
Covers both traditional and digital material categories, including how each behaves under different handling, curing, and finishing conditions.
- Metal alloys, gypsum products, waxes, and acrylics - properties and typical failure modes
- Ceramics and composite materials used in restorations, including firing and layering behavior
- Digital materials: milling blanks, 3D-printing resins, and their processing requirements
- Physical property vocabulary: tensile strength, thermal expansion, dimensional stability, viscosity
Questions in this domain are rarely pure memorization. Expect scenario-style items that describe a handling problem - a material warping, fracturing, or failing to bond - and ask you to identify the likely cause or correct process step. That format rewards understanding material behavior, not just naming materials.
Anatomy, Terminology, and Articulation Quick Hits
Domain 2 (Anatomy) is the second-heaviest domain at 17-19%, and it pairs closely with Domains 3 and 4 since all three depend on shared oral-structure vocabulary.
Domain 2: Anatomy
Tooth morphology, occlusal landmarks, and craniofacial structures relevant to prosthetic fabrication.
- Tooth numbering systems and surface/cusp terminology
- Occlusal relationships and how anatomic landmarks influence restoration design
- Muscle and joint anatomy affecting jaw movement
Domain 3: Terminology and Principles (6-8%) & Domain 4: Articulation (6-8%)
Smaller in weight but conceptually linked - articulation questions assume fluency in terminology.
- Standard dental lab terminology used across case instructions and lab prescriptions
- Articulator types, mounting procedures, and how they simulate jaw movement
- Bite registration concepts and how they translate to articulator settings
Because these three domains combine for roughly a third of the exam, weak terminology fluency quietly costs points across all of them, not just on terminology-labeled questions.
Safe Working Practices and Regulations Recap
Domain 7 (Safe Working Practices, 12-14%) and Domain 1 (Industry Regulations and Scope of Practice, 8-10%) together make up nearly a quarter of the exam, yet candidates often under-review them because they feel less "technical" than materials or anatomy.
Domain 7: Safe Working Practices
- Personal protective equipment and airborne particulate hazards from grinding and polishing
- Chemical handling, storage, and labeling requirements in a lab setting
- Equipment-specific safety procedures for kilns, milling units, and casting equipment
Domain 1: Industry Regulations and Scope of Practice
- Scope-of-practice boundaries between dental technicians and licensed dentists
- Regulatory frameworks governing dental laboratory operations
- Recordkeeping and case documentation expectations
The Last-Week Cheat Sheet Schedule
If you only have seven days left, don't try to relearn everything. Instead, allocate review time proportional to domain weight, front-loading the two heaviest domains.
Domain 5: Materials
- Rework material-property scenario questions
- Drill traditional vs. digital material differences
Domain 2: Anatomy + Domain 6: Impressions and Models
- Review tooth morphology and landmark terminology
- Compare traditional impression techniques with digital scanning workflows
Domain 7 and Domain 1
- Review PPE and hazard-handling scenarios
- Refresh scope-of-practice boundaries
Domain 3 and Domain 4 + Full Mix
- Review terminology and articulator mounting concepts
- Run full mixed-domain practice sets to simulate exam pacing
This schedule works because it mirrors exam weighting rather than a generic study calendar - for a longer-range version of this plan spanning several weeks, use the timeline in the CDT Study Guide 2026: How to Pass on Your First Attempt.
Renewal Numbers to Memorize
Passing the exams is not the finish line. CDT certification is renewed annually, and the continuing-education requirement is specific enough that it belongs on this cheat sheet.
Annual CE Requirement: 12 Hours Total
- 1 hour: Regulatory Standards credit
- 6 hours: Scientific credits
- 5 hours: Additional credits (elective category)
Missing the Regulatory Standards hour specifically - even while over-completing Scientific hours - can put a renewal at risk, so track categories separately rather than just totaling hours.
Before you schedule anything, confirm current testing windows against the handbook revision date - the handbook currently in effect was revised March 1, 2026 - and cross-check available dates using CDT Exam Dates 2026: Testing Windows, Deadlines & Scheduling. If you're still weighing whether the credential is worth the time and the $1,200 investment, Is the CDT Certification Worth It?

Once you've reviewed this page a few times, the most efficient next step is running full-length timed practice sessions that mimic the FastTest interface and question mix - that's exactly what the practice tests on the main CDT practice test site are built for. Combining this cheat sheet with realistic practice questions on our practice platform is the fastest way to convert a one-page review into exam-day confidence.
