The Honest Answer on the CKBD Passing Score
If you searched for "CKBD passing score" hoping for a clean number like "you need 70 percent," here is the straightforward truth: the National Kitchen & Bath Association (NKBA) does not publish a verified numerical cutoff for the current Certified Kitchen and Bath Designer Fundamentals Exam. Nor does it publish the question count, the scored versus unscored item split, or a numerical time limit in the public sources reviewed for this article.
That is frustrating, but it is also useful to know. Many sites fill this gap by recycling old figures, such as 100-question or 200-question formats and four-hour windows, that belonged to earlier versions of the program or to entirely different credentials that happen to share the "CKBD" acronym. We do not assert those older specifications for the current bundle, and you should not plan around them.
For context on how this fits the broader picture, see our related analysis of the CKBD pass rate, which explains why NKBA's non-disclosure of pass-rate data also limits what anyone can responsibly claim.
Why There Is No Single Score: Two Exams, Two Standards
The current Certified Kitchen and Bath Designer credential requires two separate components, and "passing" means clearing both:
| Component | What It Evaluates | How "Passing" Works |
|---|---|---|
| Fundamentals Exam | Understanding and application of the NKBA Kitchen & Bath Planning Guidelines in scenarios | Numerical cutoff, question count, and timing currently unverified publicly |
| Portfolio Exam | A real kitchen and bath project where you were designer of record | Juried review against NKBA Graphic & Presentation Standards |
Both must be completed within one year of the bundle purchase. That one-year window is an administrative access limit, not an exam timer, so it governs when you must finish rather than how long any sitting lasts.
Because the Portfolio is judged by NKBA-certified portfolio jurors rather than scored by a machine, the idea of a single universal "score" does not map neatly onto the credential. If you want the full picture of how the pieces connect, our overview of what CKBD certification is walks through the program end to end.
What We Can and Cannot Say About Fundamentals Scoring
Being precise about the unknowns is more valuable than guessing. Here is what remains unverified from current public issuer sources:
- The current number of Fundamentals questions
- The item format and the split between scored and unscored questions
- The numerical time limit
- The numerical passing cutoff
- Whether the exam is open-book, whether a calculator is permitted, whether it is adaptive, and what the live-proctoring rules are
What we can say is that the Fundamentals Exam explicitly tests the fifth-edition Kitchen & Bath Planning Guidelines, and that it frames questions around understanding and applying them in scenarios. That tells you the style: expect to reason from a design situation to the correct guideline-driven decision, not to simply recall a definition.
Our companion piece on how hard the CKBD exam is discusses difficulty in qualitative terms for the same reason: the hard numbers are not public.
The Portfolio Exam: Passing Against a Standard
For many candidates, the Portfolio is where the real work lives. It requires a genuine kitchen and bath project completed by you as designer of record, submitted as eight PDF deliverables and reviewed to NKBA Graphic & Presentation Standards:
Kitchen Deliverables
Four PDFs documenting the kitchen portion of your project.
- Kitchen drawings
- Specifications
- Design statement
- Before and after photographs
Bath Deliverables
The same four deliverable types, applied to the bath project.
- Bath drawings
- Bath specifications
- Bath design statement
- Bath before and after photographs
Critically, these eight PDFs are portfolio requirements. They are not written-exam domains and they carry no published scored weights. A strong portfolio is one where drawings, specifications, and narrative agree with each other and with the planning guidelines. A juror reading your kitchen drawings and then your design statement should find a coherent story with no contradictions.
Choose your project carefully. Because you must be the designer of record, you cannot submit work you did not lead. And because the same planning guidelines underpin both exams, a project that visibly follows clearances, work-center layout, and ventilation logic reinforces what you are tested on in Fundamentals.
What the Fundamentals Exam Actually Tests
Since the cut score is unpublished, your best lever is content mastery. The reference behind Fundamentals is the fifth-edition Kitchen & Bath Planning Guidelines, linked to the 2024 International Residential Code and CSA B652 Accessible Dwellings (2023), with comparison to the National Building Code of Canada. The public description highlights several clusters worth knowing.
Accessibility and Universal Design
The reference covers accessible planning with wheelchairs, mobility aids, and grab bars. Expect to reason about clear floor spaces, maneuvering, and where reinforcement is needed. This connects directly to the Universal Design and Clear Floor Spaces topics.
Interior Environment
Published guidance includes wall blocking and bracing, storage systems, counter bracing, flooring, tile slip ratings, indoor air quality, sustainable materials, energy and water conservation, comfort, and acoustics. These map to topics such as Cabinetry & Casework, Finishes & Materials, Functional Storage, Indoor Air Quality, and Sustainable Design.
Building Systems
Published guidance includes smart-home controls, illumination and lighting controls, kitchen-island power, kitchen and bath ventilation calculations, and fire and life-safety locations. These align with Electrical Planning, Lighting Planning, Systems Coordination, and Code Compliance.
Key Takeaway
Ventilation calculations are named explicitly in the public reference description. Practice working them by hand and understanding the logic, because calculator rules for the exam are unverified and you should not rely on one being available.

Where to Spend Your Preparation Time
With no official weights, a sensible approach is to group the 24 public topics by how they behave in scenario questions, then ensure you have no weak cluster. The groupings below are editorial, not official.
| Cluster | Topics (from the public list) | Why It Matters |
|---|---|---|
| Circulation and clearances | Egress & Passageways; Doorways & Hardware; Clear Floor Spaces | Dimensional reasoning that recurs across kitchen and bath scenarios |
| Kitchen planning | Primary Activity Centers; Secondary Activity Centers; Seating Areas for Dining; Kitchen Fixtures & Fittings; Kitchen Equipment | Work-center logic and equipment placement |
| Bath and support spaces | Bathroom Fixture & Fittings; Laundry Equipment; Clothing Storage; Home Offices & Gyms | Fixture clearances and adjacent-space planning |
| Outdoor spaces | Outdoor Kitchens; Outdoor Baths | Extending guideline logic beyond the interior |
| Materials and casework | Cabinetry & Casework; Finishes & Materials; Functional Storage | Specification-level decisions that also feed your Portfolio |
| Performance and systems | Indoor Air Quality; Electrical Planning; Lighting Planning; Systems Coordination; Code Compliance | Calculation- and code-driven questions |
| Inclusive and sustainable design | Universal Design; Sustainable Design | Cross-cutting principles that touch many scenarios |
Our CKBD study guide expands on how to turn these clusters into a working plan, and you can pressure-test your recall with the CKBD practice tests.
Fees, Retakes, and the One-Year Clock
Because a failed attempt has real cost and timing consequences, it helps to understand the mechanics before you sit for anything. All figures below come from the current public program details.
| Item | Detail |
|---|---|
| U.S. bundle price | $950, covering Fundamentals plus Portfolio |
| Membership | Current NKBA membership required; no non-member exam tier is published |
| Included retakes | One retake of each component |
| Later Fundamentals retake | $195 |
| Later Portfolio retake | $295 to $395 |
| Waiting periods | 14 days and 30 days for first retakes, then 30 days |
| Reactivation | $450, grants six months, subject to deadline and eligibility |
| Completion window | Both components within one year |
The practical implication: the included retakes are a safety net, not a plan. Waiting periods mean a failed Fundamentals attempt costs you at least a couple of weeks, and with a one-year completion window, a late first attempt leaves little slack. If the window lapses, the $450 reactivation option buys six months but remains subject to deadline and eligibility.
Eligibility Comes Before Any Score Matters
No score helps if you cannot sit for the credential. Eligibility follows one of three paths, with documentary evidence and references applying:
- An NCIDQ or architect credential
- 30 relevant academic credits plus three years of industry experience, including one year as a designer
- Seven years of industry experience, including three years as a designer
Note that the industry route takes effect June 1, 2026. If you are relying on experience rather than a degree or credential, confirm the current requirements and your documentation before purchasing the bundle, since the one-year clock matters. Our CKBD requirements guide covers qualification details, and the CKBD exam dates article addresses scheduling.
A Domain-Sequenced Preparation Schedule
One generic caveat applies: without a published passing score, build your schedule around coverage and a finished Portfolio, not a target percentage. Here is an example ordering that pairs the Portfolio with the content it reinforces.
Circulation and Clearances
- Egress & Passageways, Doorways & Hardware, Clear Floor Spaces
- Redraw clearances from your own portfolio project to check them
Kitchen and Bath Planning
- Activity centers, seating, fixtures, equipment, bathroom fixtures
- Draft your kitchen and bath specifications in parallel
Systems, Air, and Code
- Electrical, lighting, ventilation calculations, systems coordination, code compliance
- Work ventilation problems by hand
Universal and Sustainable Design, Then Review
- Accessibility, grab-bar reinforcement, sustainability topics
- Finalize the eight PDFs and take timed practice sets
Sequencing circulation first is deliberate: clearance logic recurs everywhere, so early fluency pays off across later topics. Systems and code come before accessibility review so that the cross-cutting topics can tie them together at the end.
After You Pass: Maintenance and Career Context
Earning the credential is not the finish line. Maintenance requires 20 approved hours, equal to 2.0 CEUs, every two years. The renewal fee total is not verified in the sources reviewed, so confirm it directly with NKBA when you approach your cycle.
As for career value, the credential is valued by kitchen and bath design firms, remodelers, showrooms, and cabinetry dealers that want documented competence in the planning guidelines. We avoid quoting earnings here because no verified figures are available to us; our salary guide and ROI analysis treat the topic qualitatively, and the CKBD jobs page covers where certified designers work. Between now and test day, the main practice test site offers scenario-style questions that mirror the application-focused format.
Frequently Asked Questions
NKBA does not publish a verified numerical passing cutoff for the current Fundamentals Exam in the public sources reviewed. The Portfolio Exam is juried against NKBA Graphic & Presentation Standards rather than reduced to a published percentage.
The current question count, item format, scored versus unscored split, and numerical time limit are unverified. Older 100-question, 200-question, and four-hour specifications should not be assumed for the current bundle.
Yes. The credential requires both the Fundamentals Exam and the separately juried Portfolio Exam, and both must be completed within one year.
The $950 bundle includes one retake of each component. Later Fundamentals retakes cost $195 and Portfolio retakes cost $295 to $395, with waiting periods of 14 and 30 days for first retakes and 30 days afterward.
No official weights are published. The 24 topics are the public Topics Covered list for the fifth-edition planning guidelines, and the largest scored domain remains unpublished.
