The Council for Interior Design Qualification (CIDQ) administers the NCIDQ Exam. CIDQ, which is composed of regulatory boards from across the United States and Canada, takes seriously its responsibility to protect the public. Accordingly, CIDQ specific education and work experience requirements exist to be eligible to sit for the NCIDQ Examination. You must have official education transcripts and they must include a minimum of 60 semester or 90 quarter credit hours of post-secondary interior design coursework that encompasses a certificate, degree, or diploma from an accredited institution to be eligible. You must also have experience, which consists of up to 1,760 hours of interior design work experience earned prior to graduation. Regardless, CIDQ also warns that meeting CIDQ's education and work experience requirements does not guarantee that a candidate will meet their jurisdiction's requirements to be a licensed interior designer. Individuals are reminded to check with their jurisdiction regarding those specific requirements.
The Interior Design Fundamentals Exam (IDFX), Interior Design Professional Exam (IDPX), and the Interior Design Implementation Exam (IDIX) exams are scored by computer.  Scores are reported on a scale ranging from 200 (0 correct) to 800 (all correct), with the passing point anchored at 500. Results for each exam are processed within 6-8 weeks of the close of the window. Candidates who sat for the exam will receive an email notification once the score has been processed and is available to view in MyNCIDQ. CIDQ takes this time to guarantee that all scores are fair and accurate.

In collaboration with interior designer practitioners, educators, and testing professionals, CIDQ has set a passing point (or cut score) for each NCIDQ Exam. Meeting the passing standard for all three exam sections and achieving NCIDQ certification demonstrates that a candidate is competent to practice in a way that protects the health, safety, and welfare of the public.  The passing point does not change based on your location, the number of candidates taking the exam, or the performance of other candidates taking the exam.
