The exam consists of three parts: the Interior Design Fundamentals (IDFX), the Interior Design Professionals Exam (IDPX) and the Practicum. Those who pass all three sections are considered NCIDQ certified. NCIDQ certification is the globally recognized standard for interior designers.

Unlike traditional academic exams, which assess knowledge through recall, the NCIDQ exam samples the body of knowledge and skills deemed necessary for the profession by examining a sample of questions across each topic, including ergonomics, sustainability, codes, lighting, and project management. This sampling strategy is based on widely accepted scientific research methods and is the basis of all western testing methodologies.
