Answer : It depends on what you want to do with your degree. If you want to be an interior designer, then yes, it is worth it. If you want to be an architect, then you should go to architecture school instead. Interior design schools offer a curriculum that teaches students the basics of design, color theory, space planning, and furniture selection. After completing a degree from an interior design school, many graduates choose to become certified through the National Council for Interior Design Qualification (NCIDQ). Certification is not required in order to work as an interior designer, but it can help increase your chances of finding a job.
