Someone may wish to specialize and develop technical knowledge specific to one area or type of interior design, such as residential design, commercial design, hospitality design, healthcare design, universal design, exhibition design, furniture design, and spatial branding. Interior design is a creative profession that is relatively new, constantly evolving, and often confusing to the public. It is not an artistic pursuit and relies on research from many fields to provide a well-trained understanding of how people are influenced by their environments.
A formal education program, particularly one accredited by or developed with a professional organization of interior designers, can provide training that meets a minimum standard of excellence and therefore gives a student an education of a high standard. There are also university graduate and Ph.d. programs available for those seeking further training in a specific design specialization (i.e. gerontological or healthcare design) or those wishing to teach interior design at the university level.
