Final answer:
Interior designers are not required to receive certification through the National Council for Interior Design Qualifications.
Step-by-step explanation:
The statement that all interior designers are required to receive certification through the National Council for Interior Design Qualifications is False. While certification is recommended and often preferred by employers, it is not legally required in most states. However, many states do have requirements for interior designers, such as education and experience, that must be met in order to practice professionally.
