- The Gaming and Vending Technician (GVT) outline from ETA International contains five major categories, numbered 1.0 through 5.0.
- ETA states exam questions derive from its published competency requirements, so the outline is your primary study map.
- No official percentage weights are published; do not trust any source claiming exact domain weightings.
- The written exam has 75 questions in 2 hours, with a 75% passing score.
How the Official GVT Outline Is Built
The Gaming and Vending Technician (GVT) credential is issued by ETA International as a stand-alone, entry-level certification for technicians with an electronics background. Its scope comes from a four-page competency document titled "GAMING AND VENDING TECHNICIAN - GVT, Competency Requirements," which ETA links from its Specialty Certifications page. ETA states that examination questions derive from these competencies, which makes the document the closest thing to an official blueprint.
The outline has five major headings, numbered 1.0 through 5.0, in this order:
- Money Handling
- Electrical Fundamentals
- Basic Electronics Concepts
- Computer Hardware, Networking, and Display Technologies
- Safety Precautions and Protection
Notice how the progression works. It opens with the thing a gaming or vending machine exists to do, which is accept and dispense money. It then builds from electricity to electronics to computing and display hardware, and closes with safety. If you're new to the credential, the overview of what GVT certification is gives the wider context before you dig into domain-level detail.
The Exam Format Behind the Domains
Knowing the domains is only half the picture. You also need to know the container they arrive in. The GVT is a written knowledge exam with these published parameters:
| Element | What ETA publishes |
|---|---|
| Number of questions | 75 |
| Time allowed | 2 hours |
| Passing score | 75% |
| Hands-on component | None required |
| Delivery | Trapeza computer or paper/pencil, proctored by ETA Certification Administrators; remote proctoring via ExamRoom.AI arranged through ETA |
| Exam fee | $105 USD (remote proctoring adds $16 and is payable again on a retake) |
Several details are not published in the sources reviewed: how many questions are scored versus unscored, the exact mix of item types, and the raw number of correct answers needed to reach 75%. Be wary of any site that states those figures confidently. For more on the threshold itself, see the GVT passing score breakdown, and for full pricing mechanics, the GVT certification cost guide.
Testing-room rules also shape how you practice. Scratch paper and a non-programmable or scientific calculator are permitted under ETA testing rules, photo ID is required, and phones are prohibited. Used scratch paper is surrendered, and you cannot leave the room once testing starts. Because calculators are allowed, expect that numeric questions in the electrical and electronics domains are worth practicing with a calculator in hand. GVT-specific open-book and adaptive-testing rules were not verified, so assume neither applies unless ETA tells you otherwise.
Domain 1: Money Handling
This is the domain that most clearly separates GVT from a generic electronics credential. A gaming or vending machine is, at its core, a device that takes in value, validates it, and pays out. The competency heading is simply "MONEY HANDLING," and for a technician it covers the hardware and logic by which a machine deals with currency and payment.
What to expect in Money Handling
Think about the money path through a machine from the customer's hand to the cash box or the payout, and about what a technician must understand to keep that path working and accurate.
- How a machine accepts, validates, and rejects currency or other payment inputs
- How change is calculated, stored, and dispensed
- Why cash accountability and accurate records matter to the operators who own the machines
- The failure modes that stop money flowing: jams, misreads, dirty sensors, worn mechanisms
Because the outline text itself is brief, the safest preparation is to understand the underlying mechanics rather than memorize product names. Know how a validator distinguishes genuine from invalid inputs in principle, how coin and bill paths are kept clear, and how a technician verifies that a machine is paying correctly after a repair. Candidates coming from pure electronics backgrounds often under-prepare here because the content feels operational rather than technical, so give it deliberate attention. The GVT cheat sheet is a useful place to consolidate the quick-recall items once you've studied the concepts.
Domain 2: Electrical Fundamentals
The second domain is the electrical foundation everything else rests on. A technician servicing machines installed in venues, hallways, and break rooms needs to be fluent in how electrical quantities behave before touching a power supply or tracing a fault.
Core ideas to master
The relationships between voltage, current, resistance, and power are the language of this domain. Practice using them in both directions: given a circuit, predict the behavior; given a symptom, reason back to a cause.
- Ohm's law and power relationships, including quick calculator-assisted problems
- Series versus parallel circuit behavior and how measurements differ in each
- AC versus DC and where each appears inside a machine
- Using a multimeter to measure voltage, current, and resistance, and interpreting what you read
Since a scientific calculator is allowed in the testing room, drill numeric problems until the arithmetic is automatic and your attention can go to setting the problem up correctly. Most mistakes at this level come from unit slips and misapplied formulas, not from advanced theory. Note that GVT is not named in ETA's Common Formulas Sheet authorization, so do not plan on having a formula sheet handed to you; commit the key relationships to memory instead.
Key Takeaway
Treat Domain 2 as the multiplier for Domains 3 and 5. Solid electrical fundamentals make component behavior and electrical safety questions far easier to reason through.
Domain 3: Basic Electronics Concepts
Where Domain 2 deals with electrical quantities, Domain 3 moves to the components and circuits that use them. This is the domain most directly aligned with the "electronics background" ETA describes for the credential's intended candidates.
Component and circuit literacy
Expect the exam to test whether you understand what common parts do, how they are identified, and how they fail.
- Passive components such as resistors, capacitors, and inductors, and what each does in a circuit
- Semiconductors such as diodes and transistors, including their basic function as switches and rectifiers
- Power supply sections: transformation, rectification, filtering, and regulation
- Reading basic schematics and recognizing common symbols
- Digital versus analog signals and basic logic concepts
The most productive approach is to tie each component to a symptom. A failed filter capacitor suggests ripple and unstable operation; a shorted rectifier diode suggests blown fuses. Questions that connect a component's role to a plausible machine fault are a natural fit for a technician-level exam. If you're gauging how demanding this material will feel, the GVT difficulty guide discusses what tends to challenge candidates.
Domain 4: Computer Hardware, Networking, and Display Technologies
Modern gaming and vending equipment is, increasingly, specialized computing hardware wrapped in a cabinet. The fourth domain reflects that reality with three related strands: computer hardware, networking, and display technologies.
Three strands, one machine
Study these as parts of a single system rather than separate topics, because a real machine fault often crosses the boundaries between them.
- Computer hardware: processors, memory, storage, boards, and how a machine boots and runs its software
- Networking: how machines connect to a network, basic addressing and connectivity concepts, and what to check when a connection drops
- Display technologies: how screens and indicators present information, and how to distinguish a display fault from a driver or signal fault
This is also the domain where a vending-focused candidate and a gaming-focused candidate may feel different levels of comfort. Someone who services video gaming equipment may already know display and board-level issues well, while a vending technician may be stronger on electromechanical topics and weaker here. Self-assess honestly and give extra time to whichever strand is newest to you.
Domain 5: Safety Precautions and Protection
The final domain is safety, and it deserves more study time than its position at the end of the list suggests. ETA's outline organizes safety content under this single major heading, and electrical safety appears as a subsection of Domain 5 rather than as a separate sixth category. That distinction matters if you've seen other summaries claiming six domains; the official count of numbered headings is five.
Safety and protection themes
Technicians work with mains power, stored energy, and moving mechanisms, often in public venues. The exam expects you to know how to protect yourself, the equipment, and the public.
- Electrical safety practices when working on or near energized equipment
- Lockout and de-energizing concepts before servicing
- Grounding and protection devices such as fuses and breakers, and why each exists
- Awareness of stored energy in capacitors and other components after power is removed
- Handling static-sensitive components without damaging them
- Safe handling of cash boxes, heavy cabinets, and mechanical assemblies
Safety questions tend to have a clearly correct "safest" answer, so the winning habit is to ask what a careful, trained technician would do before anything else. For the broader credential picture, including the code of conduct acceptance ETA's badge criteria mention, review the GVT requirements guide.
Weighting: What Is and Isn't Known
Candidates naturally want to know which domain counts most. The honest answer is that ETA has not published percentage weights for the five categories, and no highest-weighted category was verified. The header count of five is simply the number of competency headings in the supplied document.
| Domain (issuer order) | Official weight published? | Practical emphasis |
|---|---|---|
| 1.0 Money Handling | No | Machine-specific; easy to underestimate |
| 2.0 Electrical Fundamentals | No | Foundation for Domains 3 and 5 |
| 3.0 Basic Electronics Concepts | No | Components, supplies, schematics |
| 4.0 Computer Hardware, Networking, and Display Technologies | No | Three strands; breadth matters |
| 5.0 Safety Precautions and Protection | No | Includes electrical safety subsection |
The practical conclusion is to avoid gaming the exam by skipping domains. With 75 questions spread across five areas and a 75% bar, a weak domain can cost you meaningfully, and you can't know in advance how heavily any single area is represented. The GVT pass rate article explains why published pass-rate claims should be treated cautiously as well.
Sequencing Your Preparation Around the Domains
Rather than a generic schedule, order your preparation by dependency. Electrical fundamentals unlock electronics, and both unlock the safety reasoning, so study them in a deliberate sequence.
Electrical Fundamentals
- Drill voltage, current, resistance, and power relationships with a calculator
- Practice multimeter measurement scenarios
Basic Electronics Concepts
- Link each component to its role and a typical failure symptom
- Trace power supply sections end to end
Computer Hardware, Networking, and Display Technologies
- Spend extra time on whichever of the three strands is least familiar
Money Handling and Safety
- Review currency path mechanics and change handling
- Finish with safety and protection, then full timed practice
Schedule safety last on purpose: by then, you can apply it to everything you've studied. Take timed practice sets against the 2-hour limit using the GVT practice tests, and revisit weak domains afterward. For a fuller study framework, see the GVT study guide, and for structured instruction options, the GVT training overview.
Who Hires Technicians with This Skill Set
The five domains map directly onto the day-to-day work of keeping machines operating: handling money accurately, diagnosing electrical and electronic faults, servicing computing and display hardware, and working safely. Employers of such technicians typically include vending operators, amusement and gaming equipment service companies, and venues that maintain their own machines. Because the credential is entry-level and intended for people with an electronics background, it can function as a documented baseline of knowledge. Browse the GVT jobs overview and the GVT salary guide for a qualitative look at the market, and the GVT ROI analysis if you're weighing the investment.
Once certified, the credential runs for a 4-year term. General maintenance, per ETA's maintenance page, involves a Certification Maintenance Form, either 10 continuing-education hours per year (40 over four years) or a supervisor-completed Employer Verification for relevant employment, and a $25 annual fee ($100 per cycle). ETA recommends annual submission. An older maintenance overview PDF lists a different international annual fee, so international candidates should confirm the current figure directly with ETA.
Frequently Asked Questions
ETA's competency requirements list five major categories, numbered 1.0 through 5.0: Money Handling; Electrical Fundamentals; Basic Electronics Concepts; Computer Hardware, Networking, and Display Technologies; and Safety Precautions and Protection. Electrical safety is a subsection of the fifth category, not a sixth domain.
No official percentage weights or highest-weighted category were verified. ETA publishes the competency headings but not weightings, so prepare across all five areas rather than relying on a claimed breakdown.
No. The GVT is a written knowledge exam of 75 questions in 2 hours with a 75% passing score, and no hands-on exam is required. Even so, the content assumes practical familiarity with how machines work.
ETA provides one eligible free retake after a 30-day wait, completed within one year of the first sitting. It is not available merely to improve a passing score. If you test remotely, the $16 remote proctoring fee remains payable on a retake. Details on timing are covered in the GVT exam dates guide.
ETA publishes the competency requirements as a four-page PDF linked from its Specialty Certifications page. It carries a 2013 copyright, so confirm current exam details on ETA's site. For definitions of the credential itself, see what GVT is.
