Blueprint Overview: Why 2026 Looks Different
The CEDIA Certified Integrated Systems Technician exam is built from a published blueprint, and the version that matters for anyone testing after September 1, 2026 is blueprint v1.1, issued March 28, 2026. That blueprint splits the exam into six content areas, each carrying a specific percentage of the scored questions. Understanding those percentages is the single most useful thing you can do before you open a textbook, because it tells you exactly where the exam's weight actually sits.
This guide walks through all six domains in the order CEDIA lists them, explains what each one actually tests, and shows how the weighting should shape your study plan. If you haven't yet confirmed you meet the eligibility path for sitting the exam, it's worth reviewing IST Requirements 2026: Eligibility, Prerequisites & How to Qualify before you invest time in domain-level prep.
Domain 1: Project Process (6.00%)
Project Process
This is the smallest domain on the exam, but it sets the frame for everything else a technician does on a job site. It covers how a technician fits into the broader project lifecycle - from receiving scope and specifications to coordinating with other trades and closing out a job cleanly.
- Reading and interpreting project documentation, drawings, and scopes of work
- Coordinating installation timelines with electricians, builders, and other trades on site
- Following site safety protocols and documentation standards during handoff
Because this domain is only 6.00% of the exam, don't overinvest hours here relative to the bigger domains - but don't skip it either, since every question on a 150-item exam has weight.
Domain 2: Infrastructure (12.67%)
Infrastructure
Infrastructure questions test the physical backbone that every integrated system depends on: pathways, power, and low-voltage wiring practices that need to be correct before any equipment goes in.
- Low-voltage wiring standards, cable pathways, and conduit/raceway planning
- Power requirements, grounding, and surge protection for connected equipment racks
- Structured cabling layout decisions that affect later equipment placement
Infrastructure sits in the middle of the weighting scale, but it's foundational - mistakes here tend to surface as failures in later domains like Equipment Installation and Systems Verification & Testing, so it pays to be genuinely solid rather than just passable.
Domain 3: Equipment Installation (18.00%)
Equipment Installation
This is one of the three heavyweight domains. It focuses on the physical mounting, connection, and configuration of the devices that make up a residential or light-commercial integrated system.
- Proper mounting techniques for displays, speakers, racks, and control processors
- Device-level cabling and termination practices for A/V and network equipment
- Manufacturer specification compliance during physical installation
Domain 4: Communication Systems (18.67%)
Communication Systems
Communication Systems is nearly tied with Equipment Installation for second-largest domain, and it tests the networking and signal-distribution knowledge that ties devices together into one working system.
- Network topology, IP addressing basics, and wired/wireless connectivity for AV devices
- Signal distribution across A/V matrices, HDMI/network extenders, and control buses
- Troubleshooting communication failures between devices on a shared network
Candidates coming from a pure installation background often underestimate this domain because it's more conceptual than hands-on wiring. If networking fundamentals feel shaky, that's a strong signal to slow down before test day - a point covered in more depth in How Hard Is the IST Exam? Complete Difficulty Guide 2026.
Domain 5: Integrated Systems (33.33%)
Integrated Systems
Integrated Systems is, by a wide margin, the largest domain on the exam - a full third of all scored questions come from this area. It covers how individual subsystems (audio, video, lighting, security, control) are configured to work together as a single cohesive experience for the end user.
- Programming and configuring control systems to coordinate multiple subsystems
- Integrating lighting, climate, security, and A/V into unified scenes or automation logic
- Diagnosing conflicts between subsystems that were installed correctly on their own but don't communicate properly together
Key Takeaway
Because Integrated Systems alone is worth 33.33% of the exam, treat it as its own dedicated study block rather than folding it into general review - it deserves roughly a third of your total prep time by design.
Domain 6: Systems Verification & Testing (11.33%)
Systems Verification & Testing
The final domain covers what happens after installation and integration are complete: confirming the system actually performs as designed before handing it off to the client.
- Functional testing procedures for A/V, network, and control subsystems
- Documenting test results and identifying performance issues before client sign-off
- Basic troubleshooting methodology for isolating faults across integrated subsystems
This domain overlaps conceptually with Integrated Systems, since verifying a system requires understanding how its parts were meant to work together in the first place - another reason those two domains reward being studied close together rather than far apart.
| Domain | Weight |
|---|---|
| 1. Project Process | 6.00% |
| 2. Infrastructure | 12.67% |
| 3. Equipment Installation | 18.00% |
| 4. Communication Systems | 18.67% |
| 5. Integrated Systems | 33.33% |
| 6. Systems Verification & Testing | 11.33% |
How the Domains Show Up on Exam Day
The domain weights aren't abstract - they map directly onto the item mix you'll see on the actual exam. The standard IST exam, per handbook v2.0 (issued August 14, 2026), consists of 150 scored multiple-choice questions plus 15 unscored pilot questions, delivered in a 3-hour window at a Kryterion Webassessor test center or via remote online proctoring. It's closed-book, though the testing software provides a basic calculator and a notepad. The blueprint's percentages determine how those 150 scored items are distributed across the six domains - so a domain worth 33.33% will represent roughly a third of the questions you actually see.
Standard registration costs USD 200 for CEDIA members and USD 300 for non-members, with a USD 80 retest fee if you need a second attempt. Separately, CEDIA is running a one-time beta window from September 1-30, 2026, priced at USD 50 for members and non-members alike. The beta adds one extra hour of testing time and grades candidates on the same 150 questions being finalized for the standard exam, but its results and the associated passing standard aren't released until October 2026 - so beta candidates are testing before the score line is even set. For a full cost breakdown of both paths, see IST Certification Cost 2026: Complete Pricing Breakdown, and for exact scheduling details see IST Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
Allocating Study Hours to Match the Weighting
A weighted blueprint is only useful if it actually changes how you spend your study hours. The simplest approach is to allocate time proportionally: if Integrated Systems is 33.33% of the exam, it should get roughly a third of your total study time - not an equal sixth alongside Project Process at 6.00%. A short, blueprint-aligned timeline might look like this:
Foundations
- Review Domain 1 (Project Process) and Domain 2 (Infrastructure) - lighter domains, faster to clear
Installation & Communication
- Deep dive into Domain 3 (Equipment Installation) and Domain 4 (Communication Systems)
Integrated Systems Focus
- Dedicate the full week to Domain 5 given its 33.33% weight
Verification & Full Review
- Cover Domain 6 (Systems Verification & Testing), then run mixed practice across all six domains
This isn't a rigid formula - a candidate with years of hands-on installation experience but limited network background will need to rebalance toward Communication Systems. For a more complete week-by-week methodology, see IST Study Guide 2026: How to Pass on Your First Attempt. And once you're in final review mode, a condensed reference like IST Cheat Sheet 2026: One-Page Review of Must-Know Facts can help you drill weighted domains quickly rather than re-reading full notes.
If you want to test your recall against realistic, domain-weighted questions before exam day, running through practice questions on our practice test platform is one of the fastest ways to see which domains still need work. Many candidates use timed practice sessions specifically to simulate the 3-hour, 150-question pressure of the real exam.
Frequently Asked Questions
There's no required order, but starting with Domain 1 (Project Process) and Domain 2 (Infrastructure) makes sense since they're smaller and build context for the heavier domains that follow, especially Domain 5 (Integrated Systems).
Yes. The blueprint allocates a fixed percentage of the 150 scored questions to each of the six domains, so every standard exam form draws from all six areas according to those set weights.
Yes. The beta, running September 1-30, 2026, grades candidates on the same 150 questions being finalized for the standard exam and follows the same six-domain structure, though it adds an extra hour of testing time and the passing standard isn't set until October 2026.
At 33.33%, Integrated Systems reflects the core job function of an IST: making separate subsystems like A/V, lighting, security, and control work together as one coordinated experience, which is the most complex and error-prone part of the work.
