Although you don't necessarily have to major in interior design, a bachelor's degree or higher in the discipline provides the best foundation for a career, according to the Foundation for Interior Design Education and Research.
Upon the completion of a bachelorâs degree students may then sit for a licensure exam in interior design. The prerequisites for the National Council for Interior Design Qualification (NCIDQ) exam include at least 2 years of college education and a total of 6 years of work experience and education combined. Upon clearing the exam, students are certified as âLicensed Interior Designersâ.
