About the NCIDQ Exam
The NCIDQ Exam, developed by the Council for Interior Design Qualification (CIDQ), measures interior design competency to protect public health, safety, and welfare. CIDQ reports that 29 U.S. states, Washington, D.C., Puerto Rico, and eight Canadian provinces regulate interior design, and NCIDQ Certification meets the regulatory standard in more than half of U.S. states and most Canadian provinces. The exam has three sections: IDFX (Interior Design Fundamentals Exam, 115 questions, 3 hours) covers programming, conceptual design, and schematic design; IDIX (Interior Design Implementation Exam, 130 questions, 4 hours), which replaced the PRAC Practicum exam in 2026, covers design development and construction documentation; and IDPX (Interior Design Professional Exam, 115 questions, 3 hours) covers construction administration and project management. Each section includes 15 unscored pretest questions.

Frequently Asked Questions
Is the NCIDQ vocabulary game free?
Yes. The game is free to play with no sign-up. Signing in adds AI explanations for any term.
How does the NCIDQ vocabulary game work?
Each round shows a clue for one of 20 NCIDQ terms. Guess the term in six tries: green means the right letter in the right spot, yellow means the letter is in the term but in another spot, and gray means it is not in the term. After the round, read the explanation and play the next term.
Where do the NCIDQ 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 the NCIDQ exam pass rate?
CIDQ publishes pass rates by section, not an overall NCIDQ rate. For the Spring 2026 administration, the pass rates were 53% for IDFX, 60% for IDPX, and 61% for IDIX, the Implementation Exam that replaced PRAC in 2026. From Spring 2022 to Spring 2026, IDFX pass rates ranged from 48% to 55%.
How hard is the NCIDQ exam?
The NCIDQ is considered challenging due to its comprehensive coverage of interior design practice and its focus on protecting public health, safety, and welfare. IDFX covers programming through schematic design (3 hours), IDIX covers design development and construction documentation (4 hours), and IDPX covers construction administration and project management (3 hours). All three sections mix multiple-choice questions with drag-and-place, fill-in-the-blank, and hot-spot items, so expect to apply codes and read drawings rather than only recall facts. Most successful candidates study 100-150 hours per section over 2-4 months.
