Additional Information

  • Upon acceptance into this category, Intern members will be given an eligibility date to write the NCIDQ (National Council of Interior Design Qualification) examination, within a three-year period. The Council establishes standards of competence, ensuring that an interior designer who is NCIDQ certified creates interior spaces that are not only esthetically pleasing, but also functional and safe.
