If you've considered a career in interior design, you may have wondered where might be the best place to begin your education. You may have seen magazine advertisements or television commercials promoting an interior design correspondence course. It may be a tempting way to learn how to begin a career in interior design, especially if you are looking for a flexible option. However, be wary of any self-directed course, especially if it is not an accredited program or run by a reputable school. According to the American Society of Interior Designers (ASID), a typical self-directed interior design correspondence course does not meet the minimum educational requirements for someone to practice interior design.
