Many people use the term "interior design" and interior decorating" interchangeably. Interior design is the art and science of understanding people's behavior to create functional spaces within a building. Decoration is the furnishing or adorning of a space with fashionable or beautiful things. Both disciplines provide valuable expertise to remodel projects and new home projects. In short, interior designers may decorate, but in general decorators may not have full design qualifications.
The interior design process follows a systematic and coordinated methodology including research, analysis and integration of knowledge into the creative process to satisfy the needs and resources of the client. Many U.S. states and Canadian provinces have passed laws requiring interior designers to be licensed or registered documenting their formal education and training and many of them specifically require that all practicing interior designers earn the NCIDQ Certificate to demonstrate their experience and qualifications. By contrast, interior decorators require no formal training or licensure. for more, please visit NCIDQ website National Council for Interior Design Qualification
