Exam Snapshot: The Numbers You Must Know
Before you touch a single practice question, memorize the mechanics. AVIXA administers the CTS-I exam exclusively at Pearson VUE testing centers, and the format doesn't change from region to region. Here's the entire exam reduced to its raw numbers:
| Detail | Value |
|---|---|
| Total questions | 110 (10 non-scoring pilot questions) |
| Time allowed | 150 minutes |
| Question types | Multiple-choice and hotspot |
| Passing score | 350 out of 500 (scaled) |
| Prerequisite | Valid CTS credential |
| Recommended experience | 3-4 years in AV installation |
| U.S. fee (member) | $490 |
| U.S. fee (nonmember) | $590 |
| Eligibility window | 120 days |
If you want the full context behind each of these numbers, the CTS-I Study Guide 2026 walks through how they translate into a study plan. This cheat sheet is meant to be the fast-reference version you print, bookmark, or screenshot the week before test day.
Domain Breakdown at a Glance
The CTS-I exam outline has six domains, and they are not weighted evenly. Ignoring this weighting is one of the fastest ways to waste study time on low-yield content. Here is the exact breakdown:
| Domain | Weight |
|---|---|
| 1. Implement Pre-Installation Activities | 17% |
| 2. Practice Ongoing Project Responsibilities | 12% |
| 3. Conduct Site Rough-In/First-Fix | 12% |
| 4. Install AV Systems | 39% |
| 5. Perform AV Systems Closeout | 12% |
| 6. Conduct Post Project Activities | 8% |
Domain 4 alone accounts for nearly two out of every five questions. For a full walkthrough of what falls under each of these six areas, see the CTS-I Exam Domains 2026 guide, which maps sub-tasks to each domain in detail.
Key Takeaway
If you only have time to deeply review one domain, make it Domain 4 (Install AV Systems). It carries more exam weight than Domains 2, 3, and 6 combined.
Registration, Fees, and Eligibility Mechanics
The CTS-I is not an entry-level credential - AVIXA gates access behind a prerequisite and a fee structure that rewards membership. Here's what to confirm before you register:
- Prerequisite: You must already hold a valid CTS credential. There is no path to CTS-I without it.
- Experience recommendation: AVIXA recommends 3-4 years of hands-on AV installation experience, though this is guidance rather than a hard gate checked at registration.
- Fee structure: $490 for AVIXA Premium or Elite members versus $590 for nonmembers in the U.S. - a meaningful gap if you're paying out of pocket.
- Eligibility window: Once approved, you have 120 days to schedule and sit for the exam at a Pearson VUE center.

If you're unsure whether your background satisfies AVIXA's expectations, the CTS-I Requirements guide covers eligibility in more depth, and CTS-I Exam Dates 2026 explains how to plan around the 120-day clock.
What Each Domain Actually Tests
Domain names on an outline can sound abstract. Here's what each one translates to in practical, on-the-job terms.
Domain 1: Implement Pre-Installation Activities (17%)
This covers everything that happens before a technician touches a cable - site surveys, reviewing drawings and scopes of work, verifying that infrastructure matches design intent, and coordinating with other trades.
- Reading and interpreting architectural and AV drawings
- Verifying electrical, network, and structural readiness
- Confirming scope of work against contract documents
Domain 2: Practice Ongoing Project Responsibilities (12%)
This domain tests project communication and documentation discipline - change orders, status updates, safety compliance, and coordinating with project managers and clients throughout the install.
- Documenting changes and deviations from scope
- Maintaining safety standards on active job sites
- Communicating progress to stakeholders
Domain 3: Conduct Site Rough-In/First-Fix (12%)
Rough-in is where cable pathways, mounts, and backboxes go in before finishes are installed. Expect questions on cable types, pathway planning, and code-compliant rough-in practices.
- Selecting and routing appropriate cabling
- Mounting hardware and backbox placement
- Coordinating rough-in timing with other trades
Domain 4: Install AV Systems (39%)
The core of the exam. This domain covers terminating cable, mounting and calibrating displays and speakers, configuring control and DSP systems, and integrating equipment racks. Because it's worth more than a third of your score, gaps here are the most likely reason candidates fall short of 350.
- Signal flow for video, audio, and control systems
- Rack build-out, termination, and labeling standards
- Device configuration and system integration
Domain 5: Perform AV Systems Closeout (12%)
Closeout activities include system testing, punch lists, client walkthroughs, and final documentation such as as-built drawings.
- Verification and testing procedures
- Punch list resolution and sign-off
- As-built documentation and training handoff
Domain 6: Conduct Post Project Activities (8%)
The smallest domain, covering warranties, maintenance planning, and ongoing client support after the install is complete.
- Warranty terms and service agreements
- Preventive maintenance scheduling
- Post-install support and troubleshooting escalation
Notice the pattern: Domains 1, 3, and 4 together represent the physical build process (68% of the exam), while Domains 2, 5, and 6 represent the surrounding project management and support lifecycle.

Question Format and Scoring Logic
Two things trip up first-time CTS-I candidates: the hotspot questions and the pilot items.
- Hotspot questions ask you to click a location on a diagram or schematic rather than choose from a text list. These test whether you can visually identify components, cable runs, or rack positions - not just recall facts.
- Pilot questions are 10 of your 110 questions that don't count toward your score. AVIXA uses them to test future exam content. You won't know which ones are pilot questions, so treat every question as if it counts.
- Scoring is reported on a 0-500 scale, and 350 is the minimum passing score. For a full explanation of how the scaled score is calculated and what it means for your study targets, see CTS-I Passing Score 2026.
Key Takeaway
With 150 minutes for 110 questions, you have roughly 80 seconds per question. Practice pacing with a timer so hotspot items don't eat disproportionate time.
Final-Week Review Plan by Domain
A generic study calendar doesn't help much this close to test day - what matters is allocating your remaining hours according to domain weight. Here's a compressed, CTS-I-specific final review sequence:
Domain 4: Install AV Systems
- Review signal flow diagrams for video, audio, and control
- Drill rack termination and labeling standards
- Practice hotspot-style questions on schematics
Domain 1: Pre-Installation Activities
- Re-read drawing symbols and scope-of-work language
- Review site readiness checklists
Domains 3 and 5: Rough-In and Closeout
- Compare rough-in cable pathway rules against finish-stage testing procedures
- Review punch list and as-built documentation requirements
Domains 2 and 6: Project and Post-Project
- Review change order and communication protocols
- Review warranty terms and maintenance scheduling
Full Timed Practice
- Take full-length timed practice exams at ../ to simulate the 150-minute, 110-question format
- Review missed questions by domain, not just overall score
This is a compressed final-review sequence, not a full prep plan - if you're starting from scratch, the CTS-I Study Guide 2026 lays out a longer runway. And if you want to see how your practice scores compare to what's typically needed to clear 350, the CTS-I Pass Rate data is worth reviewing alongside your progress.
Renewal and Credential Maintenance
Passing the exam isn't the finish line - CTS-I is renewed on a three-year cycle, and maintaining it requires 30 renewal units within that period. Plan for this early rather than scrambling in year three:
- Renewal units can typically come from continuing education, industry events, and approved training.
- Track your units as you earn them rather than reconstructing them right before your renewal deadline.
- Letting the credential lapse can mean additional steps to reinstate it, so calendar your three-year renewal date the moment you pass.
Who This Certification Is Built For
CTS-I is designed for people already doing hands-on AV installation work - not for those just entering the field. Typical holders include AV installation technicians, lead installers, systems integrators, and field engineers who run job sites rather than design them on paper. Employers hiring for these roles frequently list CTS-I as a preferred or required credential because it verifies field-level competency across the same six domains tested on the exam.
If you're weighing whether the credential is worth pursuing given your career goals, the ROI analysis on CTS-I and the CTS-I Salary Guide both dig into the practical payoff.
