NCIDQ Exam exam requirements & cost
Straight from the certifying body — separate from what we charge for the study portal.
The NCIDQ Exam is taken as three separate sections of 3, 3 and 4 hours, and each section adds 15 unscored pretest questions that cannot be told apart from scored ones. The CIDQ blueprints (December 2025, implemented in 2026) divide the scored content into 16 areas: IDFX covers Existing Conditions, Pre-Design, Programming, Space Planning, Preliminary FF&E and Finishes, and Schematics; IDPX covers Feasibility Studies, Scheduling and Budgeting, Contracts, Procurement, and Permitting, Construction Process, and Site Observation and Close-Out; IDIX covers Codes and Life Safety, Integration and FF&E, Construction Documents, Consultant Drawing Coordination, and Construction Specifications and Schedules. CIDQ reports a scaled score for each section on a 200-800 scale and the passing score is 500; it does not publish how answers convert to the scaled score. Not every real item is a plain multiple-choice question. CIDQ reports a scaled score for each section and the passing score is 500. It does not publish how answers convert to that score, so the result in the portal mock is only a self-check. CIDQ sets the fees for the application and for each section and they were not part of the sources used here, so no figure is quoted. Confirm the current fees with CIDQ before you apply. The content outline spreads questions across 16 areas; the largest are IDIX - Construction Documents (11.7%); IDPX - Contracts, Procurement, and Permitting (8.9%); IDIX - Integration and FF&E (7.0%). The full list of areas and weights is on the portal exam page. CIDQ sets the education and work-experience requirements for the NCIDQ Exam; confirm them in the current Candidate Handbook before you apply. The portal is a practice aid built on the published blueprints: it is not a copy of the exam, it combines three separately taken sections into one mock, and it does not predict your scores.
