The most reliable source is the Council for Interior Design Accreditation web site. The official list of Council-accredited programs [www.accredit-id.org] is kept up to date there and has links to many of the schools' Web sites.
The exam eligibility requirements include interior design education and interior design work experience. For details, review the exam requirements [www.ncidq.org/exam/examreq.htm] at NCIDQ's Web site.
The National Council for Interior Design Qualification is an independent, nonprofit organization that works to identify to the public those interior designers who have met the minimum standards for professional practice by passing the NCIDQ Examination. Like the “bar” exam for the legal profession, the NCIDQ Examination measures the competency of interior designers to practice as professionals.
