Founded in 1975, the American Society of Interior Designers is the oldest, largest and leading professional organization for interior designers.  The Society celebrates its 35th anniversary in 2010, but the rich, vibrant history of the organization goes back further--much further--to the founding of its predecessor organizations, the American Institute of Interior Designers (AID) and the National Society of Interior Designers (NSID).  ASID inspires and enriches its members by promoting the value of interior design, while providing indispensable knowledge and experiences that build relationships. The Society's 18,000 practicing interior designers work in all areas of both commercial and residential design.  Professional members of ASID must pass rigorous acceptance standards: They must have a combination of accredited design education and/or full-time work experience and pass a two-day accreditation examination administered by the National Council for Interior Design Qualification (NCIDQ).
