The National Council for Interior Design Qualification (NCIDQ) Examination

To practice as a professional interior designer in any US state or Canadian province that regulates the interior design profession,  you must pass the complete National Council for Interior Design Qualification (NCIDQ) Examination. This exam is also required for professional membership in American Society of Interior Designers (ASID), International Interior Design Association (IIDA), and Interior Designers of Canada (IDC), the largest and most respected associations of interior designers in the world today.

Who is NCIDQ?

The NCIDQ was conceived in the late 1960's to establish standardized credentials for interior designers. It was incorporated as a non-profit organization in 1974, with the support of the then major professional designer associations, the American Institute of Decorators (AID) and the National Society of Interior Designers (NSID). Just one year later, In 1975, these 2 organizations merged to become ASID, which continues to rely upon and support the NCIDQ examination process today.

NCIDQ's members are the state and provincial boards that regulate the profession of interior design. NCIDQ does not have individual members. However, designers who pass the NCIDQ exam are assigned a unique Certificate Number, which they may use to identify themselves as "NCIDQ Certified."

What is NCIDQ's role within the interior design profession?

NCIDQ's core mission is to "protect the health, life safety and welfare of the public by establishing standards of competence in the practice of interior design." NCIDQ "serves to identify to the public those interior designers who have met the minimum standards for professional practice by passing the NCIDQ Examination." (Source: www.ncidq.org/who/index.asp)  

 

Qualifying for and completing the exam

The NCIDQ Exam is held twice a year, in the Spring and the Fall, simultaneously in some 50+ locations throughout the United States and Canada. In order to be eligible to take the exam, you must meet specific requirements for college-level design education and professional work experience, typically a six-year combination of both. These requirements do vary substantially by state, so consult the appropriate state regulatory agency. Once you have been qualified as eligible to sit for the exam by your state or province (or by NCIDQ directly in non-licensed jurisdictions), you must pre-register and pay a fee.  

The NCIDQ is a two-day exam, typically given on a Friday and Saturday. It is administered under standardized environmental conditions and strictly regulated testing procedures. The exam is offered in three sections which are graded separately, including 2 multiple-choice sections on Friday (Section I in the morning and Section II in the afternoon), and the full-day design/drafting "Practicum" Section III on Saturday. The Practicum is administered in two separate sessions (Part I in the morning and Part 2 in the afternoon) though both Parts are graded together, and must be passed as one section. 

If you fail any of the three individual sections, you can retake just that part (or parts) at a later date, after paying an additional fee. NCIDQ does not impose a limit on the number of times you can retake any failed section of the exam. Nor does NCIDQ impose a time limit on how long you may take to pass the complete exam, however, the regulatory agencies of individual states or jurisdictions may impose such limits.  

So, how many applicants actually pass?

According to the NCIDQ, "Approximately 75 percent of all candidates who enter the examination process eventually pass. More than 18,000 candidates have successfully completed the exam."  (Source: www.ncidq.org/faqs/index.htm

Designer competencies: the "practice analysis study" process

The NCIDQ has developed the exam using rigorous, independently validated methods and procedures. To ensure that the exam content accurately reflects professional practice, NCIDQ updates its comprehensive survey of interior designers ("the Practice Analysis Study") every 5 years, most recently in 2003. NCIDQ uses this research to determine the minimum competencies required for interior designers. Based on this, test specifications are developed to determine the relative importance of each competency as reflected in the exam. For example, it determines the number of questions in exam Sections I and II devoted to a specific knowledge area. 

NCIDQ's 6 "knowledge areas" of interior design

NCIDQ has identified six "knowledge areas" representing the practice of interior design, and tests a designer's minimum competence in each area.  David Ballast, AIA, a respected authority on the NCIDQ exam characterizes these "performance domains" in his book  "The Interior Design Reference Manual: A Guide to the NCIDQ Exam, 3rd Ed." as follows:

 

Programming

Information gathering
Information analysis and presentation

 

Schematic Design

Developing and presenting design concepts
Space planning
Communication methods
Selection of materials, finishes, and furnishings
Coordination, budgeting, and scheduling

 

Design Development

Elements of design
Principles of design
Interior construction
Architectural woodwork
Finishes
Finalizing design development and presentation to the client

 

Contract Documents

Construction drawings
Construction specifications
Structural systems
Mechanical -and electrical systems
Lighting
Acoustics

 

Contract Administration

Bidding and negotiation of contracts
Construction and FF&E contracts
Project management and contract administration

 

Professional Practice

Interior design business practices
Owner-designer agreements
Sustainable design
Building codes
Exiting
Barrier-free design

 

NCIDQ exam content and format

Within each of these six knowledge areas, NCIDQ has identified specific professional tasks in which designers must demonstrate competence, through application of appropriate knowledge and skills.  These areas of professional knowledge and skill are tested in the three separate sections of the NCIDQ exam as follows (the source for this information is NCIDQ Examination Study Guide, 3rd Edition, page 9-19):

 

Section I:  Principles and Practices of Interior Design (multiple-choice) 

Section I, a 3 1/2  hour multiple-choice test on Friday morning, has 150 questions, of which 125 questions are graded and 25 are non-graded, experimental questions. Section I questions are divided about equally among the knowledge areas of Programming (33%), Schematic Design (32%), and Design Development (35%). 

 

Section II: Contract Documents and Administration (multiple-choice) 

Section II, a 3 hour multiple-choice test on Friday afternoon, has 150 questions, of which 125 questions are graded and 25 are non-graded experimental questions. Section II questions are divided about equally among the knowledge areas of Contract Documents (35%), Contract Administration (32%), and Professional Practice (33%).

 

Section III:  Schematics and Design Development (Part I and Part II - design practicum)

Section III, is a 7 hour design and drafting "Practicum" on Saturday, administered in 2 parts: Part I is 4 hours in the morning, and Part 2 is 3 hours in the afternoon.

According to NCIDQ, Section III  "requires you to create a design solution for a 3,000 to 4,000 square foot (300-400 square meter) space. The purpose of the practicum is to assess your design decision-making and skill in a multifunctional design project." (Source: NCIDQ Examination Study Guide, 3rd Edition, page 19.) 

Section III questions are divided about equally among the knowledge areas of Programming (25%), Schematic Design (24%), Design Development (26%), and Contract Documents (35%). Contract Administration and Professional Practice are addressed fully in Section II, and are not assessed again in the Practicum.

 

Exam Sections I & II: multiple-choice testing of "practice area" knowledge and skills 

NCIDQ provides the following information to help exam candidates understand the specific tasks that interior designers perform as a part of each area of design practice, and the related professional knowledge and skills for which they will be tested.

Exam study tips

Start studying for the exam 6-12 months in advance, if possible, but no later than 3 months before the exam. 
Try to form or join a local study group. 
Read broadly from the NCIDQ Bibliography.
Order the NCIDQ Study Guide and a few sample practicum problems. Study for Section III (practicum) by doing the problems under realistic test conditions.
Read David Ballast's  The Interior Design Reference Manual: A Guide to the NCIDQ Exam, 3rd Ed., from cover to cover. The read it again. Then do the exam exercises in the back.
Use flash cards to study for Sections I and II.

 

Exam-day and test-taking tips

Get a good night's sleep. If you are traveling a distance to the test site, consider staying overnight in a local hotel to reduce fatigue and stress and save time that morning.
Eat breakfast.
If you live near the testing center, make a visit to familiarize yourself with the facilities.
Arrive at the test site early, so you are not worrying about directions, parking, registration lines, or "getting a good seat." Late arrivals will be turned away!
Bring a sweater in case the exam room is cold.
Bring a small cushion to sit on, if you are concerned about sitting on a metal drafting stool for hours.
Be sure to bring to the testing center your exam admission letter and photo ID. If you do not have a photo ID, you may substitute two other forms of identification, each with your name and signature.
Be sure to note any change of address on the admission letter, which is collected after completion of your last exam section. 
Be sure to return to the testing center from lunch break promptly, and to follow all instructions read to you by the Proctor. 
Do NOT bring to the exam site books or reference materials (including dictionaries or language dictionaries), pagers, or cell phones.  Proctors are instructed to confiscate these items and return them to you after the exam. 
Do not bring food or beverages into the test site without prior approval for medical reasons.
Candidates taking Sections I or II (multiple-choice on day 1) may bring the following: No. 2 pencils, erasers, and a non-programmable calculator with single memory
Candidates taking Section III (design practicum on day 2) may bring the following:, non-programmable calculator with single memory, pens, pencils, highlighters, triangles, graph paper, post-it notes, t-square, erasers (not electric), manual pencil sharpener, portable drafting board or flat illustration board (similar to poster board), tape, related small drafting equipment/tools, mass-produced templates (1/8" inch scale), tracing paper/bumwad, architectural scale, and white-out (as long as answers/drawings are legible)
Place only permitted items on your desk.
Answer all multiple-choice questions to the best of your ability. Do not skip questions. 
Do not ask Proctors to explain a question. They are not permitted to comment on exam content.
Request a "Candidate Comment Form" if you wish to express a concern about the exam to NCIDQ.   
Manage your allotted test-taking time appropriately.  The exam room will either have a visible clock, or the proctors will post the time every 30 minutes. The following guidelines may help you: Maximum time for Section I is 3 1/2 hours, from 8:30 am to 12:00 pm. Maximum time for Section II is 3 hours, from 2:00 pm to 5:00 pm. Maximum time for Section III, part 1 is 4 hours, from 8:30 am to 12:30 pm. Maximum time for Section III, part 2 is 3 hours, from 2:30 pm to 5:30 pm.  (See more information on time management for Section III above.)
Leave time during all sections of the exam to review your work.
During the practicum, be sure to complete the tasks that offer more points, and complete the lesser tasks last.
As you read the programming portion (practicum) use a marker to highlight each room name, and connect them with colored lines to other room names, to create a crude bubble diagram. It speeds up completing the adjacency matrix. 
Label everything on the drawing (practicum). Make it easy for the jurors to fid what they are looking for.
