Definition of Interior Design

Interior design is a distinct profession with specialized knowledge applied to the planning and design of interior environments that promote health, safety, and welfare while supporting and enhancing the human experience. Founded upon design and human behavior theories and research, interior designers apply evidence-based methodologies to identify, analyze, and synthesize information in generating holistic, technical, creative, and contextually-appropriate design solutions.

The Council for Interior Design Qualification (CIDQ) is the premiere certifying organization for interior design professionals. CIDQ develops and administers the three-part NCIDQ Examination, which tests interior designers’ knowledge of core competencies required for professional practice in the industry. Read the full definition of Interior Design.

What Does An Interior Designer Do?

An interior designer is a professional who has acquired the expertise, knowledge, and skills, through a combination of education, experience, and examination, to create interior environments that meet the requirements of and present solutions for their clients. They have extensive knowledge of current codes, standards, and regulations and adhere to these in their work, while paying strict attention to the importance of accessibility, functionality, health, safety, and welfare to their clients.

Interior Designers – Educated Professionals

Interior design is a highly technical, complex and skilled profession. Practitioners make critical decisions that have real impact on the public health, safety, and welfare. NCIDQ Certified interior designers undergo formal education, thousands of hours of paid, supervised experience, and an internationally-recognized, eleven-hour certification exam to become certified. The NCIDQ Exam covers seven areas that capture the core competencies of interior design: building systems, codes, construction standards, contract administration, design application, professional practice and project coordination. The exam’s contents are regularly updated to ensure they reflect the most current knowledge required to design safe, functional and innovative interior spaces.

The Case for Reasonable Regulation

Why is professional certification and regulation so important? Enacting reasonable regulations secures equitable access to the design marketplace and reflects the important role qualified interior designers play on the design and construction team.

Eliminating Marketplace Barriers

Certified interior designers should have the same opportunities to succeed in the design marketplace as other design professionals. The laws should not protect one profession to the exclusion of another. Allowing qualified interior designers to stamp and submit their own construction documents for building permits eliminates cost, time and bureaucracy. Support practice rights for qualified interior designers.

Interior Design & Regulated Construction

Why would a certified interior designer need to independently apply for building permits? By law, building permits must be secured before commercial construction can begin. Certified interior designers perform complex work that can often require a building permit and should not need to seek approval from another design discipline to obtain one.

Interior Design Advocacy

Texas Laws - Title Act with Permitting Privileges: Texas has a title act, meaning that the state does not regulate the practice of interior design, only the title of Registered Interior Designer (RID) and allows for RIDs to sign off on permitting in code-impacted environments.

Texas Board of Architectural Examiners: TBAE's mission is to serve the State of Texas by protecting and preserving the health, safety, and welfare of the Texans who live, work, and play in the built environment through the regulation of the practice of architecture, landscape architecture, and interior design. 

Registered Interior Designer: In Texas it is voluntary for an interior designer to register with TBAE. To become a RID, an interior designer must first pass the NCIDQ exam and complete a minimum of 12 hours of continuing education each year on topics pertaining to the health, safety, and welfare of the public. Breanna Taylor is a RID, No. 12714.

American Society of Interior Designers: Through education, knowledge sharing, advocacy, community building and outreach, ASID strives to advance the interior design profession and, in the process, to demonstrate and celebrate the power of design to positively change people’s lives. They lead interior designers in shared conversations around topics that matter: from evidence-based and human-centric design to social responsibility, well-being, and sustainability. Breanna Taylor is a Professional Member of ASID.
