| Item | What to Know |
|---|---|
| Credential | Certified Kitchen and Bath Designer (CKBD) |
| Issuer | National Kitchen & Bath Association (NKBA) |
| Components | Fundamentals Exam + juried Portfolio Exam |
| Completion window | Both parts within one year |
| U.S. bundle fee | $950; current NKBA membership required |
| Included retakes | One retake of each part |
| Reference tested | Fifth-edition Kitchen & Bath Planning Guidelines |
| Maintenance | 20 approved hours / 2.0 CEUs every two years |
Two Gates: Fundamentals and Portfolio
Gate One: The Fundamentals Exam
Fundamentals is scenario-oriented. You are expected to read a planning situation and apply the guideline logic: clearances, work-area relationships, accessibility provisions, ventilation, lighting and code references. Memorizing a number without understanding why the guideline exists is the classic way to lose points on application-style questions. For a candid look at how demanding this is, see How Hard Is the CKBD Exam?
Gate Two: The Portfolio Exam
The Portfolio is not a written test. NKBA-certified portfolio jurors review a real kitchen and bath project on which you served as designer of record. Submissions are judged against the NKBA Graphic & Presentation Standards. A beautiful project with sloppy drawings can still fall short, because presentation quality is part of what is being evaluated.
Quick Contrast: What Each Part Rewards
Think of the two parts as testing different muscles.
- Fundamentals: knowledge of the planning guidelines and the judgment to apply them to a scenario.
- Portfolio: documented, standards-compliant design work on a real project you led.
Fees, Retakes and Clocks
Most candidates plan their study schedule well and their administrative schedule poorly. Pin these down early. The full picture is in CKBD Certification Cost, and the scheduling side is covered in CKBD Exam Dates.
| Item | Published Detail |
|---|---|
| Bundle fee (U.S.) | $950 |
| Membership | Current NKBA membership required; no non-member exam tier published |
| Included retakes | One retake of each part |
| Later Fundamentals retake | $195 |
| Later Portfolio retake | $295 to $395 |
| First-retake waits | 14 days (Fundamentals) / 30 days (Portfolio) |
| Subsequent retake wait | 30 days |
| Reactivation | $450 for six months, subject to deadline and eligibility |
Practical implication: the included retakes are insurance, not a plan. Because the wait before a first retake is 14 days for Fundamentals and 30 days for the Portfolio, a failed attempt late in your one-year window can run you out of runway. Start both tracks early rather than finishing Fundamentals and only then beginning to assemble project documentation.
Who Qualifies
Eligibility is route-based. You need to satisfy one of three paths, backed by documentary evidence and references. Full detail lives in CKBD Requirements.
- Credential route: an NCIDQ or architect credential.
- Academic plus experience route: 30 relevant academic credits, plus 3 industry years including 1 designer year.
- Industry route: 7 industry years including 3 designer years. This route is effective June 1, 2026.
Notice the recurring phrase "designer year." Time spent in adjacent industry roles counts toward the industry total, but each route also demands time actually spent designing. If your experience is mostly sales or installation, document your design responsibilities carefully, because references and paperwork are part of the review.
The 24 Planning Guidelines Topics
The domain list below is the publicly posted Topics Covered list for the fifth-edition Kitchen & Bath Planning Guidelines, the reference explicitly tested by the Fundamentals Exam.

High-Yield Facts by Topic Cluster
Rather than treating 24 topics as 24 silos, group them. Real scenarios blend several topics at once, such as a kitchen island that touches clear floor space, electrical planning, seating and lighting. The clusters below are an editorial grouping for review, not an official structure.
Cluster A: Movement and Space (Topics 1 to 3)
Egress & Passageways, Doorways & Hardware, and Clear Floor Spaces form the circulation backbone of every plan.
- Expect scenarios where a door swing, a passageway and a clear floor space compete for the same square footage.
- The fifth-edition reference addresses planning for wheelchairs and mobility aids, so know how access requirements reshape clearances.
Cluster B: Work and Use Zones (Topics 4 to 12)
Primary and Secondary Activity Centers, Seating Areas for Dining, fixtures, equipment, Laundry Equipment, Clothing Storage, and Home Offices & Gyms.
- Be able to explain how activity centers relate to one another, not just how each one is sized.
- Know the difference between fixtures and fittings versus equipment, since the topic list separates them.
- Do not skip the "peripheral" spaces. Laundry, clothing storage, offices and gyms are named topics.
Cluster C: Outdoor Spaces (Topics 13 and 14)
Outdoor Kitchens and Outdoor Baths are easy to under-study because they are rarer in daily practice. Because they appear as named topics, treat them as testable.
Cluster D: Interior Environment (Topics 15 to 18)
Cabinetry & Casework, Finishes & Materials, Functional Storage and Indoor Air Quality.
- The reference describes wall blocking and bracing, counter bracing, and storage systems.
- Finishes include flooring and tile slip ratings, and the interior-environment guidance extends to sustainable materials, comfort and acoustics.
- Indoor air quality links directly to ventilation, which carries into Cluster E.
Cluster E: Building Systems (Topics 19 to 22)
Electrical Planning, Lighting Planning, Systems Coordination and Code Compliance.
- Published detail includes smart-home controls, illumination and lighting controls, and kitchen-island power.
- Kitchen and bath ventilation calculations and fire/life-safety locations are named in the reference description.
- The fifth edition is linked to the 2024 International Residential Code and CSA B652 Accessible Dwellings (2023), with comparison to the National Building Code of Canada. Know which framework a scenario invokes.
Cluster F: Whole-Project Principles (Topics 23 and 24)
Universal Design and Sustainable Design cut across everything else. Expect them to surface inside other scenarios, including energy and water conservation.
Portfolio Exam Cheat Sheet
The Portfolio is where a surprising number of otherwise strong designers stumble, because it rewards documentation discipline. It requires a real kitchen and bath project completed by you as designer of record, reviewed to the NKBA Graphic & Presentation Standards.
| Space | Eight PDF Deliverables in Total |
|---|---|
| Kitchen | Drawings, specifications, design statement, before/after photographs |
| Bath | The same four deliverables |
- Choose the project early. You need before/after photographs, so a project already completed or well underway is far easier than one you hope to finish.
- Confirm designer-of-record status. The project must be genuinely yours, not a team effort where your role was minor.
- Make the specifications and drawings tell a consistent story. Jurors reviewing against presentation standards notice mismatches between plans, specs and the design statement.
- Let the guidelines show up in your design statement. Tie decisions to clearances, accessibility and ventilation logic.
What Is Not Published
A trustworthy cheat sheet admits its gaps. As of the September 30, 2026 review of NKBA's public certification and planning-guidelines pages, the following remain unverified:
- Current Fundamentals question count, item format and scored/unscored split.
- Numerical time limit for the Fundamentals Exam.
- Numerical passing cutoff. See CKBD Passing Score for how we handle this uncertainty.
- Pass rate, which is not publicly disclosed. Details are discussed in CKBD Pass Rate.
- Open-book, calculator, adaptive and live-proctor rules.
- The total renewal fee.
Key Takeaway
Older figures such as 100 or 200 questions and a four-hour limit circulate online, but they are not asserted for the current bundle. Confirm format, timing and testing rules directly with NKBA before you build your test-day strategy around any number.
Sequencing Your Review
Since the topics are unweighted, sequence by dependency rather than by perceived importance. The full approach is in the CKBD Study Guide; here is a compact version tied to the clusters above.
Space and Circulation
- Cluster A: egress, doorways, clear floor spaces.
- Start identifying and documenting your Portfolio project.
Work Zones and Outdoor Spaces
- Clusters B and C, with extra time on whichever of kitchen or bath is your weaker side.
Materials and Building Systems
- Clusters D and E, working through ventilation, electrical, lighting and code references.
Integration and Practice
- Cluster F, then mixed scenarios across all 24 topics.
- Use the CKBD practice tests to find weak spots, and finish the Portfolio package.
This ordering puts circulation first because nearly every later scenario assumes you can place clearances correctly. Building systems come later because they are easier to absorb once you can visualize the plan they serve. Timing is yours to adjust, and it should respect the one-year window and the retake waits described earlier.
Keeping the Credential
Earning CKBD is not the finish line. Maintenance requires 20 approved hours (2.0 CEUs) every two years. The total renewal fee is not verified in the sources reviewed, so check the current figure with NKBA. If you let things lapse, reactivation costs $450 and grants six months, subject to deadline and eligibility.

FAQ
Yes. On this site CKBD means the NKBA-issued Certified Kitchen and Bath Designer credential, which combines a Fundamentals Exam with a juried Portfolio Exam. See What Does CKBD Stand For? for more.
The U.S. bundle is $950 and requires current NKBA membership, with one retake of each part included. Later Fundamentals retakes are $195 and Portfolio retakes run $295 to $395.
No. They are the public Topics Covered list for the fifth-edition Planning Guidelines, retained without official scoring weights. No largest domain has been published, so study all 24.
Neither the current item count nor a numerical cut score is verified in public sources, and the pass rate is not disclosed. Confirm current details with NKBA rather than relying on older figures circulating online.
Both the Fundamentals and Portfolio exams must be passed within one year. That window is an administrative limit, not an exam timer, and retake waits of 14 and 30 days can eat into it if you start late.
