- CETa is 100 questions, two hours, $65, with a 75% passing score set by ETA International.
- Remote proctoring through ExamRoom.AI adds a $16 charge on top of the exam fee.
- One free retake is allowed within one year, though remote retakes still carry the $16 proctoring fee.
- The credential covers 20 competency domains, not the 22 chapters found in the official study guide.
What This Cheat Sheet Covers
This is a one-page-style reference for the Associate Certified Electronics Technician (CETa) exam administered by ETA International, the Electronics Technicians Association, International. It pulls together the numbers, mechanics, and domain list you need in the final stretch before test day - not a substitute for full preparation, but a fast way to confirm you have the logistics and topic coverage straight. If you still need the deeper walkthrough, pair this page with the CETa Study Guide 2026: How to Pass on Your First Attempt and the full CETa Exam Domains 2026: Complete Guide to All 20 Content Areas.
Everything below applies to the full CETa examination path rather than ETA's separate Electronics Modules route, since that's the certification most technicians pursue and the one this site's practice tests target.

Registration, Fees, and Testing Mechanics
CETa testing runs through ETA-authorized Certification Administrators using the Trapeza platform, either online at a test site or via paper delivery. If you can't get to a physical location, remote proctoring is available through ExamRoom.AI, but remote candidates must register through ETA directly and pay the $16 proctoring charge in addition to the $65 exam fee.
- Bring government-issued photo identification - no exceptions on exam day.
- You are permitted a nonprogrammable scientific calculator only.
- ETA's Common Formulas Sheet is allowed during the exam; you don't need to memorize every formula, but you should know how and when to apply each one.
- Remote retakes still carry the $16 proctoring charge, even though the exam retake itself is free within the one-year window.
For the complete scheduling picture - including how testing windows and administrator availability work - see CETa Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
Key Takeaway
Practice using a permitted nonprogrammable scientific calculator and a printed copy of the Common Formulas Sheet during your final review sessions, not just on exam day - familiarity with the sheet's layout saves time under the two-hour clock.
Eligibility Snapshot
CETa is designed for technicians with less than two years of electronics experience or training, making it the natural entry point before pursuing higher-level ETA credentials. Hands-on assessment is optional - it is not a requirement for earning the standard CETa credential, which means the exam itself is knowledge-based rather than a practical skills demonstration.
If you're unsure whether your background qualifies, or you want the full prerequisite breakdown, read CETa Requirements 2026: Eligibility, Prerequisites & How to Qualify.
The 20 Competency Domains
These are the 20 competency categories drawn from ETA's current Associate C.E.T. Basic Electronics Certification Competency Requirements. They are content categories, not percentage-weighted exam sections - ETA does not publish a breakdown of how many questions come from each domain.
Domains 1-7: Fundamentals and Hands-On Skills
Safety Precautions, Electrical Theory, Electronic Components, Electronic Circuits: Series and Parallel, Soldering - Desoldering Tools, Block Diagrams - Schematics - Wiring Diagrams, and Cabling.
- Component identification and basic circuit analysis are foundational to nearly every later domain.
- Soldering and desoldering knowledge is tested conceptually, covering tools and technique rather than a physical bench test.
Domains 8-13: Measurement, Math, and Circuit Function
Test Equipment and Measurements, Mathematics and Formulas, Power Supplies, Amplifiers, Interfacing of Electronics Products, and Digital Concepts and Circuitry.
- Meter usage and basic formula application (Ohm's Law, power calculations) show up repeatedly across question styles.
- Digital concepts introduce logic-level thinking that carries into later computer-related domains.
Domains 14-20: Applied and Emerging Technologies
Computer Electronics, Computer Applications and Software, Audio and Video Systems, Optical Electronics, Radio (RF) Communications Technology, Telecommunications Basics, and Technician Work Procedures.
- Note that ETA's official numbering skips heading 14 in its source document - the domain list here follows ETA's own consecutive numbering without inventing a missing topic.
- Technician Work Procedures closes the list, covering professional practices rather than a specific circuit type.

High-Yield Topics to Lock In
With 20 domains and no published weighting, treat every category as fair game. That said, a few areas tend to generate the most confusion for first-time candidates:
- Series and parallel circuit math - voltage divider and current divider relationships, plus total resistance/impedance calculations.
- Test equipment reading - interpreting multimeter, oscilloscope, and basic signal generator output correctly.
- Schematic and wiring diagram symbols - recognizing standard component symbols quickly under time pressure.
- Power supply stages - rectification, filtering, and regulation, and what happens when each stage fails.
- Digital logic basics - gate functions and number systems as a bridge into computer electronics questions.
If you want a candid read on how these topics translate into overall exam difficulty, see How Hard Is the CETa Exam? Complete Difficulty Guide 2026. For context on how other candidates have performed historically, review CETa Pass Rate 2026: What the Data Shows.
Maintenance and Renewal Numbers
CETa certification is valid for a four-year term. To keep it active, ETA requires one of the following, plus a maintenance fee:
- 10 continuing-education hours per year, totaling 40 hours over the four-year term, or
- The applicable employer-verification form in place of logged CE hours.
On top of the CE requirement, maintenance fees run $25 per year, totaling $100 over the four-year certification period. Build this into your long-term planning the same way you budget for the initial exam fee - it's a recurring cost of staying certified, not a one-time expense.
A Focused Final Review Week
Rather than a generic study calendar, structure your last week around the domains most likely to trip up candidates with under two years of experience - since that's exactly who CETa targets.
Circuits and Math
- Drill Electronic Circuits: Series and Parallel alongside Mathematics and Formulas - these two domains reinforce each other.
- Practice with the actual Common Formulas Sheet so it's familiar during timed conditions.
Measurement and Diagrams
- Review Test Equipment and Measurements and Block Diagrams - Schematics - Wiring Diagrams together, since diagram reading often supports measurement questions.
Applied Systems
- Cover Power Supplies, Amplifiers, Digital Concepts and Circuitry, and Computer Electronics as a connected group.
Full Simulation
- Take a full-length, timed practice run covering all 20 domains at electronicsprep.com to confirm your pacing across 100 questions in two hours.
This kind of domain-clustered review works better than a generic weekly template because it mirrors how CETa topics actually build on one another rather than treating each domain as an isolated flashcard deck.
Common Mix-Ups to Avoid
A surprising number of preparation mistakes come from confusing similar-sounding numbers or credentials rather than from not knowing the electronics content itself.
- 22 chapters vs. 20 domains: The study guide's chapter count and the competency domain count are different systems. Don't assume chapter 14 of the study guide maps directly onto "Domain 14" - the domain list follows ETA's own numbering, which skips heading 14 in the source document and runs to 21.
- ETA's CETa vs. ISCET's Associate CET: These are two distinct organizations with separate credentials that sound alike. This site's content refers specifically to ETA International's Associate Certified Electronics Technician (CETa) - keep any research you do clearly labeled by certifying body.
- Full exam vs. Electronics Modules route: This cheat sheet covers the full CETa examination path, which is the primary focus of most candidates and of this site, rather than ETA's separate modular option.
- Free retake vs. free proctoring: The retake itself is free within one year, but remote-proctoring charges still apply if you retake remotely.

Key Takeaway
Before exam day, confirm in writing which route you registered for (in-person via a Certification Administrator or remote via ExamRoom.AI) so you know exactly which fees apply and where to bring your photo ID.
