About the NCIDQ IDFX Exam
The IDFX (Interior Design Fundamentals Exam) is one of three sections required for the NCIDQ certification, administered by CIDQ at Prometric. It is a 3-hour computer-based exam of approximately 115 multiple-choice and Alternative Item Type questions covering the early phases of interior design practice. The 2026 blueprint organizes IDFX into six content areas: Existing Conditions (14%), Pre-Design (15%), Programming (16%), Space Planning (19%), Preliminary FF&E and Finishes (16%), and Schematics (20%). IDFX tests foundational knowledge typically learned during an interior design education and can be taken independently in any order among the three sections.

Frequently Asked Questions
Is the IDFX vocabulary game free?
Yes. The game is free to play with no sign-up. Signing in adds AI explanations for any term.
How do the IDFX vocabulary games work?
There are 4 games built on 20 IDFX terms. In Guess the Term, a clue describes one term and you have six tries to spell it, with green, yellow and gray letters showing how close you are. In Term Match, six terms appear as colored tiles; swap neighbors to line up three or more of the same term, and each match shows what the term means. In Term Pairs, twelve face-down cards hide six pairs of terms; flip two at a time to find each pair, and every pair you find shows what the term means. In Term Search, five terms hide in a grid of letters, reading across, down or diagonally; drag across a term to circle it, and each term you find shows what it means.
Where do the IDFX terms come from?
OpenExamPrep researched each term from the CIDQ (Council for Interior Design Qualification) content outline and primary sources, listed under Sources on this page. The game is independent study material, not an official exam resource.
What is on the NCIDQ IDFX exam?
IDFX is the Interior Design Fundamentals Exam, the foundations section of the NCIDQ. Under the 2026 blueprint it covers six content areas: Existing Conditions (14%), Pre-Design (15%), Programming (16%), Space Planning (19%), Preliminary FF&E and Finishes (16%), and Schematics (20%). It tests foundational knowledge from interior design education, including site assessment, anthropometrics, accessibility and egress, materials and color, and schematic design communication. The exam is delivered as multiple-choice and Alternative Item Type questions.
How many questions are on the IDFX exam and how long is it?
The IDFX exam contains approximately 115 questions, of which about 15 are unscored pretest items used to evaluate future questions. Candidates have 3 hours to complete the section at a Prometric test center or by remote proctoring through Prometric ProProctor. The questions are multiple-choice and Alternative Item Types, the same item styles used across the other NCIDQ sections. Effective time management is important because the heaviest-weighted areas, space planning and schematics, reward careful reading.
