The Six Domains at a Glance
Every one of the 120 questions on the base CDFO exam is drawn from one of six focus areas. Knowing the domain names cold - and roughly what each one covers - is the fastest way to triage your remaining study time. A full breakdown of subtopics lives in CDFO Exam Domains 2026: Complete Guide to All 6 Content Areas, but here's the compressed version for cheat-sheet purposes.
Domain 1: Operations
Day-to-day management of an AEC (architecture, engineering, construction) firm - workflow systems, office administration, and operational policy.
- Know how operational decisions ripple into project delivery and staffing.
Domain 2: Project Management
Coordinating scope, schedule, and resources on design-firm projects from intake to closeout.
- Focus on the administrative side of project tracking, not technical design work.
Domain 3: Human Resources
Recruiting, onboarding, staff development, and compliance issues specific to design-firm environments.
- Expect scenario questions about firm policy and personnel decisions.
Domain 4: Marketing
Business development and positioning practices used by architecture and design firms to win and retain clients.
- Understand how marketing activities tie into firm growth and reputation.
Domain 5: Finance
Budgeting, billing, and financial oversight at the firm-operations level - the base exam's finance content, distinct from SDA's separate Financial Management specialization.
- Keep this domain separate in your notes from any advanced financial-management materials; the base exam tests operational finance literacy, not specialist accounting depth.
Domain 6: Leadership
Guiding teams, decision-making, and organizational influence within a design firm's structure.
- Leadership is part of the current six-area credential, so don't skip it as an "extra."
Key Takeaway
Course-session counts from prep materials are not the same as exam domain weights - don't assume the number of class hours spent on a topic tells you how many questions it's worth.
Fees, Eligibility & Registration Mechanics
Budgeting and qualifying correctly matters as much as content knowledge - a rejected application or an unexpected fee can derail your timeline. For the full cost breakdown by scenario, see CDFO Certification Cost 2026: Complete Pricing Breakdown.
- Application fee: $75 for SDA members, $175 for non-members.
- Exam fee: $250 for members, $475 for non-members. This includes the Resource Guide and exam-preparation resources.
- Combined total: $325 for members, $650 for non-members, based on the published component fees.
- Eligibility path: A combination of AEC-firm experience and/or formal education, plus acceptance of SDA's Code of Ethics and successful completion of the examination.
If you're unsure whether your background qualifies, review the detailed eligibility criteria in CDFO Requirements 2026: Eligibility, Prerequisites & How to Qualify before you pay the application fee.
Exam Format & Scoring Logistics
The base CDFO examination is 120 multiple-choice questions, closed book, delivered under in-person proctoring. There's no calculator swap, open reference sheet, or notes allowed - you're tested purely on recall and applied judgment across the six domains listed above.
Two logistics points are worth memorizing:
- Retest policy: If you don't pass on your first attempt, SDA allows one free retest within 12 months of the initial examination.
- Proctoring: Exams are administered in person, so plan travel or testing-center logistics in advance rather than assuming a remote option.

Complete Difficulty Guide 2026 and CDFO Pass Rate 2026: What the Data Shows for a realistic picture before you schedule a date. Exact scoring thresholds are covered separately in CDFO Passing Score 2026: Exactly What You Need to Pass.
Key Takeaway
Because the exam is closed book, memorization of core terminology across all six domains - not just the ones you feel strongest in - is non-negotiable.
Renewal & Continuing Education
Passing the exam isn't the finish line. CDFO renewal runs on an annual cycle:
- Renewal deadline: January 1 each year.
- CE requirement: 18 continuing-education units, where one unit equals one hour of qualifying education.
Plan your CE hours across the year rather than scrambling in December - 18 hours is manageable if you spread it across quarterly webinars, SDA sessions, or firm-sponsored training tied to the six exam domains.
Last-Week Review Plan
If you only have a handful of study sessions left before your test date, sequence them by domain rather than by generic review blocks. This is the one place a lightweight timeline structure helps - tied directly to CDFO's six domains, not a generic study template.
Operations & Project Management
- Drill firm workflow scenarios and project-tracking terminology.
Human Resources & Marketing
- Review personnel-policy scenarios and business-development concepts.
Finance & Leadership
- Separate base-exam finance topics from specialization content; finish with leadership decision cases.
Full Mixed Review
- Run a timed, closed-book practice set spanning all six domains at the practice test platform.
Running full-length, closed-book practice questions in the final days matters more than re-reading notes. You can build that habit using timed sets on the main practice test site, which mirrors the 120-question, six-domain structure of the real exam.
Who Hires CDFO Holders
The CDFO credential is aimed squarely at professionals working inside architecture, engineering, and construction (AEC) firms who handle administration, operations, or firm management rather than design production itself. Firm principals, office managers, and administrative leaders pursue it to formalize operational knowledge across the six domains - Operations, Project Management, Human Resources, Marketing, Finance, and Leadership.
