Answer : Interior designers typically have a four-year degree in interior design or architecture. In addition to formal education, many designers gain experience interning with various design firms. Many designers also study abroad to get a well-rounded view of the field and its history. After Gaines that experience, they may start their own firms or take on other positions in the industry, such as becoming an educator or working as a consultant. Some design professionals also hold certifications from professional organizations, such as the American Society of Interior Designers (ASID) or the National Council for Interior Design Qualification (NCIDQ). And while not all states require licensure, some do regulate the profession and require passing an exam in order to practice.
