NCIDQ IDFX study plan

Build a one-page matrix mapping each major construction assembly type (wood light frame, steel frame, concrete, masonry, curtain wall) to its typical interior implications

Explain in writing how structural, mechanical, plumbing, and electrical rough-in constrain partition layout and ceiling height

Classify 20 common interior finish materials by substrate, wear layer, and typical application

Summarize fire-resistance-rated assembly concepts, including what a rating applies to and how it is interrupted

Trace the fire and life-safety code path from occupancy classification to means-of-egress requirements for three sample project types

Differentiate the roles of building code, fire code, accessibility standards, and referenced standards in a single compliance narrative

Calculate occupant load and required egress width for two worked examples

Identify which code provisions commonly drive interior partition, door, and finish decisions

Apply accessibility requirements to a restroom, a circulation path, and a door assembly using dimensional reasoning

Compare accessibility approaches across the major reference standards without relying on rote memorization

Explain how occupancy separation, travel distance, and dead-end limits interact in a layout decision

List the code topics most likely to appear on the exam and rate personal confidence on each

Convert a written program into an adjacency matrix and bubble diagram for a mid-size office or clinic

Produce two alternative blocking options and defend each with circulation, daylight, and efficiency criteria

Apply net-to-gross and circulation factor reasoning to estimate area requirements

Evaluate furniture, clearances, and ergonomic dimensions against planning assumptions

Perform a site analysis that connects orientation, climate, access, and views to interior planning decisions

Interview a mock client and translate stated needs into measurable space criteria

Test a plan against universal design and inclusive-use principles

Identify how existing-building conditions and adaptive reuse constraints alter a space plan

Calculate illuminance needs and select luminaire types for three different space functions

Explain color rendering, color temperature, glare, and control strategies in lighting design decisions

Apply acoustic fundamentals including absorption, background noise, sound isolation, and speech privacy to a plan

Identify indoor air quality strategies including ventilation, source control, and finish emissions

Assemble a drawing set outline showing plan, elevation, detail, and schedule relationships across design phases

Differentiate the purpose and content of schematic, design development, and construction documents

Map the standard division of responsibilities among owner, architect, consultant, and contractor

Outline a project delivery sequence including bidding, submittals, and construction administration basics

Complete two full-length timed practice exams under exam conditions

Categorize every missed item by domain and error type (knowledge gap, misread, calculation, judgment)

Re-drill the three weakest domains using targeted review of personal notes

Finalize a one-page formula and concept sheet for last-day review
