Quick Facts Snapshot
This page is built to be bookmarked. It condenses every hard number a Construction Documents Technologist candidate needs into one scannable reference - no fluff, no filler, just the facts governing the CSI-administered CDT exam. If you're still building your study plan from scratch, the CDT Study Guide 2026: How to Pass on Your First Attempt walks through the process in more depth. This cheat sheet is meant for the days before your appointment, or for quick lookups whenever a detail slips your mind.
Domain Weight Breakdown
CDT content is organized into eight official knowledge domains. Weighting isn't evenly distributed - two domains alone account for over a third of the scored questions. Understanding this distribution should directly shape how you allocate study time, which the CDT Exam Domains 2026: Complete Guide to All 8 Content Areas covers in full detail.
| Domain | Weight |
|---|---|
| Domain 1: Fundamentals | 13% |
| Domain 2: Project Conception and Delivery | 11% |
| Domain 3: Design Process | 12% |
| Domain 4: Construction Documents | 22% |
| Domain 5: Procurement | 10% |
| Domain 6: Preconstruction | 9% |
| Domain 7: Construction | 15% |
| Domain 8: Life Cycle Activities | 8% |
Domain 4: Construction Documents (22%)
The single heaviest domain. It covers how specifications, drawings, and related documents are organized, formatted, and coordinated across a project.
- Master the relationship between drawings and specifications
- Know standard organization formats used in specifications
- Understand how documents are coordinated to avoid conflicts
Domain 7: Construction (15%)
The second-largest domain, focused on activities and communication that happen once construction is underway.
- Understand submittal review and processing
- Know how changes are documented during construction
- Be comfortable with contract administration terminology
Key Takeaway
Construction Documents and Construction together make up 37% of the exam. If your review time is limited, prioritize these two domains before touching the smaller ones.
Registration Windows & Fees
Scheduling for the CDT exam runs through Prolydian, with testing available at Meazure Learning test centers or via remote delivery. Pricing changes depending on when you register, so timing your registration matters as much as timing your study plan. For a full cost breakdown including every fee tier, see CDT Certification Cost 2026: Complete Pricing Breakdown.
| Registration Period | Member Fee | Non-Member Fee |
|---|---|---|
| Early Registration | $425 | $685 |
| Standard Registration (Sept 18-Nov 4) | $525 | $795 |
| Final Registration (Nov 5-18) | $625 | $935 |
| Student Registration | $185 | |
A test-center appointment adds $50 on top of the base registration fee if you choose an in-person Meazure Learning location instead of remote delivery. The Fall 2026 exam window itself runs November 10-December 15, 2026 - registration deadlines close well before testing begins, so plan around the dates in CDT Exam Dates 2026: Testing Windows, Deadlines & Scheduling rather than assuming you can register at the last minute.
Exam Format at a Glance
The CDT exam consists of 120 multiple-choice questions to be completed in a two-hour testing session. That works out to an average of one minute per question, though question difficulty varies significantly by domain - some Fundamentals questions are quick recall, while Construction Documents scenarios often require working through a short situational description before selecting an answer.
- Question count: 120 multiple-choice questions
- Time limit: Two hours
- Delivery: Meazure Learning test centers or remote proctoring
- Scheduling platform: Prolydian

Must-Know References & Sources
CDT preparation centers on one core text and a set of supporting industry references. Memorizing document names alone won't get you through Domain 4 - you need to understand how these references are structured and referenced during actual practice.
Core Preparation Materials
The exam draws from the following resources:
- Project Delivery Practice Guide, third edition - the primary preparation text
- Listed CSI reference materials
- Listed AIA reference materials
- Listed EJCDC reference materials
- Source references: D1, D2, D3, D4, D5, D7, D22
Treat the Project Delivery Practice Guide as your spine - read it fully at least once before layering in practice questions. Cross-reference unfamiliar terms against the CSI, AIA, and EJCDC materials rather than relying on memory alone, since the exam tests understanding of how these documents interrelate, not just definitions in isolation.
Eligibility Recap
Eligibility for the CDT exam is intentionally low-barrier compared to many industry credentials. A high-school diploma or equivalent is the only hard requirement.
- Required: High-school diploma or equivalent
- Recommended, not mandatory: Two years of industry experience
- Alternative path: Relevant college coursework in place of work experience
This means students, early-career professionals, and career-changers can sit for the exam without waiting years to accumulate field experience. For a complete walkthrough of who qualifies and how, see CDT Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Certification & Renewal Facts
Passing the exam isn't the end of the obligation - CDT certification is time-limited and requires active maintenance.
- Validity period: Three years from certification
- Renewal requirement: 24 learning units
- Relevance rule: All units must relate to the architecture/engineering/construction/owner industry; at least half must align specifically with the CDT credential content
- Renewal fee: $160 member / $220 non-member
- Results timing: Generally released six to eight weeks after the close of the testing window
Because results take weeks rather than days, avoid making job or project commitments contingent on an immediate score. If you're still weighing whether the investment of time and money is worthwhile long-term, Is the CDT Certification Worth It? Complete ROI Analysis 2026 lays out the considerations without inflating the numbers.
Final-Week Review Plan
In the last stretch before your exam window opens, resist the urge to start new material. Instead, cycle back through the domains by weight, spending the most time on the areas worth the most points.
Construction Documents (22%) + Construction (15%)
- Re-read Project Delivery Practice Guide sections on documentation and contract administration
- Drill practice questions covering document coordination and submittals
Fundamentals (13%) + Design Process (12%)
- Review terminology and general project roles
- Revisit design-phase deliverables and sequencing
Project Conception & Delivery (11%) + Procurement (10%)
- Compare delivery method characteristics
- Review bidding and procurement procedures
Preconstruction (9%) + Life Cycle Activities (8%)
- Light review only - avoid cramming new concepts
- Confirm test-center or remote-proctoring logistics
This isn't a generic weekly template - it's ordered specifically by CDT's own domain weighting so your last full-focus days go toward the highest-value content before your window opens. For a structured plan that starts weeks earlier rather than days, revisit the CDT Study Guide 2026: How to Pass on Your First Attempt. And when you're ready to test your recall under timed conditions, practicing with realistic questions on our CDT practice test platform is one of the fastest ways to find weak spots before exam day.
Key Takeaway
Order your final review by domain weight, not by the order topics appear in your notes - Construction Documents and Construction deserve the most repetition.
