NCIDQ IDIX study plan

NCIDQ IDIX · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Building Systems, Codes, and Life Safety & Interior Construction, Materials, and Specifications

  • Map the occupancy classification and construction type logic for at least 12 building scenarios, writing the deciding code factor next to each answer

  • Trace egress travel distance, common path, and exit width calculations through three worked examples without looking at the solutions

  • Build a one-page comparison of fire-resistance-rated assembly notation as it appears on drawings versus in specifications

  • List the ten most common specification divisions used in interior projects and write one sentence on what belongs in each

Your checkpoint

A single annotated code-and-construction cheat sheet (two pages maximum) covering occupancy, construction type, egress math, and rated assembly notation, with your own worked examples.

Week 2

Building Systems, Codes, and Life Safety & Interior Construction, Materials, and Specifications

  • Solve 20 mixed life-safety scenarios involving sprinklers, standpipes, smoke compartments, and accessibility clearances, logging the reason for every miss

  • Compare five wall and ceiling finish classifications and state where each is permitted by occupancy and location

  • Draft specification language for three interior finish items using a three-part section format (summary, submittals, execution)

  • Explain the difference between a fire barrier, a fire partition, and a smoke barrier in writing without notes

Your checkpoint

A 15-question self-written quiz on life safety and interior construction with an answer key citing the reasoning for each correct option.

Week 3

Interior Construction, Materials, and Specifications & Building Systems, Codes, and Life Safety

  • Select and justify materials for four project types (healthcare, hospitality, workplace, education) with a stated performance criterion for each choice

  • Evaluate moisture, substrate, and movement-joint requirements for tile, wood, and resilient flooring in three written scenarios

  • Identify the acoustic and fire implications of five common ceiling systems and note where each fails a requirement

  • Write a substitution request review checklist covering equivalency, testing, and schedule impact

Your checkpoint

A material selection matrix for four project types with at least three products per type, each tied to a named performance or code requirement.

Week 4

Space Planning and Adjacencies & Programming and Pre-Design

  • Convert a written client program into a bubble diagram and a blocking-and-stacking diagram for a 15,000 sq ft office

  • Calculate net-to-gross ratios and assign space allocations for six departments with stated circulation assumptions

  • Draft ten interview questions that surface program requirements a client would not volunteer

  • Test three adjacency conflicts and document the resolution trade-off for each

Your checkpoint

A complete pre-design package for one hypothetical project: program summary, adjacency matrix, stacking diagram, and net-to-gross calculation with assumptions stated.

Week 5

Space Planning and Adjacencies & Programming and Pre-Design

  • Produce a scaled space plan for the week 4 program that satisfies egress, accessibility, and adjacency constraints simultaneously

  • Verify clearances at 12 fixture and furniture conditions against accessibility minimums

  • Write a programming report section that translates three client goals into measurable space criteria

  • Critique two of your own planning solutions against a stated list of five evaluation criteria

Your checkpoint

One dimensioned space plan with an overlay annotation sheet showing how each adjacency and clearance requirement is met.

Week 6

Lighting, Acoustics, and Environmental Quality & Furniture, Fixtures, and Equipment (FF&E)

  • Run lumen-method calculations for three rooms and compare results against recommended illuminance targets

  • Specify a lighting layout that meets a stated footcandle target while satisfying a power density limit

  • Select FF&E for one room type with a written justification covering durability, lead time, budget, and maintenance

  • Diagnose three acoustic problems (speech privacy, reverberation, HVAC noise) and propose a specific remedy for each

Your checkpoint

A lighting and FF&E specification package for two rooms: fixture schedule with calculations, furniture schedule with costs, and an acoustics remediation memo.

Week 7

Project and Contract Administration & Furniture, Fixtures, and Equipment (FF&E)

  • Sequence a full interior project through all phases and list the deliverable and approval at each phase gate

  • Compare three contract delivery methods and state the designer's scope and risk under each

  • Draft a furniture procurement schedule with lead times, installation sequencing, and a punch-list process

  • Review a sample change order and identify the pricing, schedule, and documentation defects in it

Your checkpoint

A one-page project phase-and-deliverable map plus a procurement and installation schedule for a 10,000 sq ft fit-out.

Week 8

Building Systems, Codes, and Life Safety & Interior Construction, Materials, and Specifications & Project and Contract Administration & Programming and Pre-Design & Space Planning and Adjacencies & Furniture, Fixtures, and Equipment (FF&E) & Lighting, Acoustics, and Environmental Quality

  • Complete two full-length timed practice exams under exam conditions and score them by domain

  • Re-study only the two weakest domains identified by the practice scores, targeting specific missed concepts

  • Recite from memory the key thresholds for egress, accessibility, and finish classification without reference materials

  • Build a personal error log of every missed question across all eight weeks and categorize the failure type

Your checkpoint

A scored practice exam report with a prioritized list of the ten concepts still needing review and a dated plan for covering them before test day.

Milestones

Week 2: Score at least 80% on your self-written life-safety quiz and be able to explain every miss without notes.

Week 4: Complete the pre-design package with all four components present and net-to-gross assumptions explicitly stated.

Week 6: Lighting calculations fall within 10% of target illuminance and the FF&E schedule totals match a stated budget.

Week 8: Average 75% or higher across both timed practice exams, with no single domain below 65%.
