A professional standard

Expertise you
can build on.

Xanthe holds NCIDQ certification, the leading credential for interior designers. Administered by the Council for Interior Design Qualification, its three-part examination measures the core competencies needed to create safe, functional, and innovative interiors. The credential supports professional regulation and public protection across the United States and Canada.

Evidence of rigor

NCIDQ certification reflects demonstrated knowledge across the practice of interior design—not just a visual point of view.

Connected to the field

Xanthe is also connected with IIDA, the International Interior Design Association. IIDA is a professional membership association—not a certification—and its community advances the interior design profession.
