Studying for the Exams

and Tools to Help Prepare

Don’t over-think the questions or be distracted by the way something is done in a specific office. The purpose of the exam is to protect public health, safety and welfare by demonstrating certified interior designers are qualified and competent in those areas. There are no tricks or hidden agendas.
The NCIDQ Exam tests the application of facts as they relate to public health, safety and welfare. It is practice-based, so the best preparation is well-rounded experience in a diversity of practice areas.
As the author and administrator of the NCIDQ Exam, CIDQ does not teach the exam or offer advice on coursework to take in preparation for it.  However, CIDQ does provide information on study groups, as a service to NCIDQ candidates, when such notices become available to CIDQ staff. Below, you can find a list of interior design association chapters who offer NCIDQ study sessions on a regular basis. CIDQ cannot validate the usefulness of such study groups, nor guarantee the availability of study groups in any specific region or time frame.
In addition, outside companies have developed study tools for the exams. CIDQ does not review or endorse any outside company's exam prep resources and is not responsible for content found in those materials. Outside test prep providers are not involved in any way with developing or scoring this exam.


All NCIDQ Exams for spring/April 2021 administration will reference the updated exam blueprints, below.


NCIDQ Exams in the spring 2021 administration will reference the building codes, below.
This list contains resources used in the creation and development of the NCIDQ Examination. CIDQ would like to thank IDEC for their assistance in updating our reference list, as well as Fairchild Books for their donation of select texts.

Effective November 24th, 2020,  CIDQ will no longer offer Practice Quizzes for sale. As an organization dedicated to measuring the competency of interior design practitioners to protect the health, safety, and welfare of the public, CIDQ believes that the development and sale of these materials are tasks best left to others. While CIDQ does not provide endorsements of any of the number of NCIDQ test prep providers, we encourage you to talk to peers and recent test takers about 3rd party preparatory materials such as practice quizzes if you are seeking these resources. CIDQ will continue to provide, at no charge, examples of exam content to demonstrate the format and functionality of the NCIDQ exam.
