Consider accredited programs. Depending upon where you plan to become an interior designer after you graduate, you may need to attend a school that is accredited. The Council for Interior Design Accreditation and the National Association of Schools of Art and Design are the two major accrediting bodies for interior design colleges. You can find out if schools you are looking at have this accreditation by talking to the program faculty or the admissions staff.
Compare costs of attending. While you may want to attend the best school possible, it must be affordable. Don't merely look at tuition, student fees and books. Also take into consideration housing, transportation and class supplies when comparing the cost between different interior design schools. You should also find out what scholarships or financial aid you qualify for as this can make a huge difference in how much it may cost to attend a particular school.
Look for student chapters of design associations. Just as you inquired about accreditation for the school, you should also ask about what opportunities are available for student involvement. Good interior design colleges offer student chapters in the American Society of Interior Designers and the International Interior Design Association.
Find a college with a location perfect for you. Where you prefer to go to school will vary from other students based on your own place in life. Students freshly graduated from high school often prefer to attend interior design schools in trendy locales such as California, Florida or New York while adult students with families prefer something closer to home.
