Interior design is the science and art of improving the interior of a structure to create a more aesthetically pleasing and healthier environment for those using the room. An interior designer is a person who plans, conducts, collaborates, and handles such improvement projects. A person can become an interior designer by taking formal education, obtaining a certificate, or by working in a related field. Interior design training will include both classroom instruction and on-the-job practical experience.

Some of the disciplines that are typically taught during interior design training include communication theory, aesthetics, construction, environmental psychology, human psychology, and furniture design. These disciplines teach designers how to communicate with their clients and how to present their designs for optimal usability. Interior designers must also learn about construction safety, as they use many types of specialized equipment, furniture, and lighting to fulfill their clients’ needs. In addition, they are expected to be familiar with ergonomics, which is related to the proper formation, placement, and use of the human body in various work environments. These principles can eliminate workplace injuries and increase productivity and profitability.

The methods interior designers use to create spaces depend on the purpose of the project, its size, the complexity of the task, and the preferences of the client. There are several approaches to architecture, including space planning, layout, and selection of materials. Interior decorators are responsible for choosing appropriate paint colors, fabrics, linens, wall coverings, furniture, lighting, and architectural structures. Interior designers must also create spaces that are functional and appealing, while at the same time creating spaces that are comfortable and safe.

In order to be an interior designer, the applicant must hold a bachelor’s degree in a program such as the Associates in Design Degree (ADHD), or a GED. ADHD candidates must have taken or be completing general education courses that include psychology, human services, marketing, and business administration, among others. Some states require individuals to be trained and certified in all of these disciplines; others require ADHD candidates have completed their GEDs and work experience in customer service or administration positions.

Candidates who are not ADHD candidates or who hold a job that does not require ADHD certification may still fulfill the criteria for becoming an interior designer. A candidate who is employed in a scientific or technical position is generally required to receive formal training and to pass a science degree. Most science degrees are completed at the college level and require about one year of classroom study and five years of internship. The curriculum will include courses in mathematics, including algebra, geometry, calculus, statistics, and physics. Students will also learn about design principles, construction techniques, computer software, and woodworking.

Many interior designers begin their careers by working in offices for retail stores or hotels. These jobs usually do not require formal training; however, there are other opportunities that do require candidates to undergo some form of formal training. For instance, a pastry chef who wants to specialize in catering might need to complete a diploma from an accredited culinary arts program. In addition to receiving formal training, many interior designers begin their careers by participating in internships. These often last for a few weeks and cover a variety of topics, from business etiquette to the history of interior design.
