Diploma programs are designed to be basic and thorough introductions into interior design or a particular aspect of the field. Typically ranging from a semester to two years long, diploma programs are very useful for two different stages of your career. First, you may elect to enroll in a diploma program to explore your interests or to be qualified for an entry level position in the interior design field. At most schools, you can transfer your diploma work towards an associate's or bachelor's degree. Second, you may be interested in a diploma program if you want to advance your career. Perhaps you have already obtained a bachelor's degree in interior design, but you want to specialize in kitchen and bath design. Participating in a diploma program designated to a particular subject will enhance your knowledge and advance your career!
