What is the NCIDQ Exam?
The National Council for Interior Design Qualification Exam is the industry standard interior design certification exam given twice per year by CIDQ — the Council for Interior Design Qualification. While it is the only nationally recognized professional interior design exam throughout the United States and Canada, testing is now available worldwide.
The NCIDQ Exam is a three-part examination that tests entry-level minimum competence in code-regulated interior design focused on public health, safety, and welfare (HSW).
Interior designers do much more than select furniture and finishes. The NCIDQ Exam tests your knowledge of human-centered design strategies and application of building codes and standards for life safety, accessibility, sustainability, FF&E, construction documents, ethical and professional business practices, and contract administration.
How important is it to take the NCIDQ Exam?
Interior designers don’t just make spaces look pretty. They design functional and inspiring environments for businesses, hospitals, restaurants, hotels, gyms, and schools. NCIDQ Certified designers create the most important spaces everywhere that people live, work, play and learn.
Why should I take the NCIDQ Exam?
Not everyone working in interior design needs to take the NCIDQ Exam. And not everyone who wants to take the exam is eligible. Earning the NCIDQ Certification differentiates you from less qualified designers and decorators. NCIDQ Certification demonstrates you have the skills. It shows you have the knowledge to create interior spaces that provide equal access and protect the public health, safety, and well-being of all occupants.
Passing the exam isn’t easy, but with your focused and dedicated preparation, it is attainable.
Get an edge on your competition by having the NCIDQ Certificate, so you can work on top-tier projects and earn more money — you deserve it.
Which states and provinces require NCIDQ Certification?
As of fall 2020, more than half of the US States, Puerto Rico, and the Canadian Provinces have some form of Interior Design legislation. These are laws regarding the scope of practice and title of Interior Designers, with and without permitting privileges. This is constantly changing at both the federal and local levels.
Interior Design laws expand business opportunities for registered interior designers. The legislation allows for Registered, Licensed, and/or NCIDQ Certified interior designers to sign, seal, and submit drawings for permitting in some states.
It's important to check with your local jurisdiction regarding their requirements before beginning your application process. Then you can prepare your paperwork to meet any jurisdictional requirements at the same time.
Even if your state does not require registration, other states you work in may require it. So it’s always a good idea to make sure you meet the highest standards. Besides, having your NCIDQ Certificate can help you earn more.
Where you can find more information:
- American Society of Interior Designers
- International Interior Design Association
- Interior Designers of Canada
- Your State Board of Architecture and Interior Design
- Your State Department of Business and Professional Regulation
Read the Qpractice guide to example state application processes so you can learn more about how to get your interior design license.
Before we dive into the details on each of the three exams, let's take a look at the latest statistics:
What do interior designers earn?
Even in times of peak employment, there aren’t enough qualified designers for the types of projects that require them. With the shifting needs of real estate, and the evolution of construction and remodeling projects post COVID-19, more qualified designers will be required to help adapt the designed environment to meet these changes.
- Associates
- Bachelors
- Masters
- Degree + certificate
- Doctorate
According to ASID, Interior Designers can earn well over $70,000 USD per year. In today's competitive economy, median salaries for NCIDQ interior designers are $16,000 higher. See our update for Interior Designer Salaries in 2020.
The NCIDQ Certificate can help you earn more
A U.S. Census Bureau report showed that professionals with certifications (apart from their college and university-awarded degrees) earn 21.38% more than those with only an educational certificate. They also do better by 33.9% than those without any educational certificate.
NCIDQ Exam statistics
More designers take the NCIDQ Exam each year because they recognize the value of the NCIDQ Certification. Interest in the NCIDQ Exam trends upwards, so it's an important milestone in your career.
Growth in total NCIDQ Certificate holders by year
Recognition of NCIDQ Certification as the “Gold Standard” for professionalism makes earning your certification even more important.

What’s on the NCIDQ Exam?
The NCIDQ Exam is updated every 5 years based on an industry survey, called the CIDQ Practice Analysis. This determines the most important skills and capabilities for a competent interior designer. Based on current industry trends for Interior Designer responsibilities and scope of practice, these form the basis of the content on test questions.
The most recent Practice Analysis report from CIDQ is in effect as of the Spring 2021 exams. The exams test understanding and application of core interior design competencies. These skills are important for obtaining building permits as allowed by law.
These are the three parts of the NCIDQ Exam
- Interior Design Fundamentals Exam (IDFX)
- Interior Design Professional Exam (IDPX)
- Practicum (PRAC)
IDFX is based more on book learning. The IDPX and Practicum Exams require the application of knowledge gained in the field.
You must complete and pass all three parts of the exam to become NCIDQ Certified within a designated period of time. This is 10 exam testing windows or approximately 5 years from the date that you're approved for all exams.
You can extend this for 2 years by starting early. Apply to take your first exam, the Interior Design Fundamentals Exam (IDFX), right after school. You can take IDFX before earning the required qualified work experience.

You’ll have four hours to complete 114 questions, and 9 questions (3 per case) do not count towards your grade. The PRAC Exam is not software specific, so it does not require CAD or Revit proficiency.
There are 3 scenarios called Case Studies, which include a series of resource tabs for reference. These are project descriptions, floor plans, reflected ceiling plans, door and hardware schedules, building codes, and lighting cut sheets or specifications.
Case studies represent the most common project types that interior designers deal with. These are multifamily residential, small, and large commercial spaces.
The Practicum Exam uses “real life” building codes:
International Building Code (IBC)(2018)
International Plumbing Code (IPC) (2018)
ICC A117.1 Accessible and Usable Buildings and Facilities (2009)
Each exam season after the tests are finalized, CIDQ releases an exam-specific subset of these building codes that apply to that season's exam only. View this document to review the Practicum Building Codes for Spring 2022.
