What Is IND Certification?

TL;DR
  • IND is ETA International's Industrial Electronics Journeyman certification, covering 16 competency categories from safety to robotics.
  • The live ETA tables list USD 80, 100 questions, two hours, and a 75% passing score.
  • The Journeyman pathway requires CETa or the complete EM1-5 foundation, plus roughly two or more years of experience.
  • There is no hands-on assessment; the exam is proctored on Trapeza online testing or paper and pencil.

What the Credential Actually Is

IND stands for Industrial Electronics, a Journeyman-level certification offered by ETA International (the Electronics Technicians Association, International). It validates that a technician understands the electrical, electro-mechanical, and control systems found in industrial plants, from safety practices and wiring codes to motors, instrumentation, PLCs, and robotics.

If you have seen the same three letters attached to other credentials, set those aside. This article is only about the ETA Industrial Electronics certification. Its scope is defined by ETA's published competency document, Industrial Electronics (IND), Competency Requirements: CET Core and Specialties, which lists the numbered exam-competency headings candidates are tested against. If you want the shortest possible orientation, our What Is IND? and What Does IND Stand For? pages cover the naming basics, while this article goes into the structure and mechanics of the exam itself.

Why the distinction matters: Study materials, pass-rate claims, and salary numbers written for other credentials that share this acronym do not transfer. Everything you prepare should trace back to ETA's Industrial Electronics competency list and ETA's published exam rules.

Who Issues It and Where It Sits on the Ladder

ETA International is a long-standing electronics certifying body, and its credentials are organized as a ladder of progression. Foundation modules (EM1 through EM5) feed into the Associate-level CETa, and Journeyman-level specialty certifications such as Industrial Electronics build on that base. Industrial Electronics is a specialty route: it takes the general electronics foundation and applies it to the plant-floor world of motors, controllers, sensors, and industrial networks.

ETA's competency document is titled around "CET Core and Specialties," which signals that the IND content is meant to sit alongside the broader Certified Electronics Technician framework rather than replace it. That framing explains a quirk in the scope that we cover below.

Exam Format and Test-Day Rules

Both of ETA's live IND tables (the Specialty Certifications page and the Additional Accredited Certifications page) specify the same exam parameters.

ItemWhat ETA Lists
Exam feeUSD 80
Questions100
Time allowedTwo hours
Passing score75%
Certification termFour years
Hands-on assessmentNone

One discrepancy deserves a mention. ETA's certification catalog booklet lists 75 questions rather than 100, and a third-party listing of the exam shows different figures again. The two live IND tables on ETA's own site agree on 100 questions, so that is the figure to plan around. Because published numbers can shift, confirm the current count with ETA when you register. For more on how the score threshold works in practice, see IND Passing Score 2026.

How the Exam Is Delivered

The exam is proctored through ETA Certification Administrators. Candidates can sit it using Trapeza online testing or traditional paper and pencil. Because there is no hands-on component, the entire evaluation is knowledge-based: you are expected to read a schematic, interpret a scenario, and select the correct answer, not demonstrate a bench skill.

Rules You Should Know Before You Arrive

  • Photo ID is required.
  • Scratch paper and a non-programmable scientific calculator are permitted under ETA rules.
  • Used scratch paper is returned to the proctor.
  • Phones are prohibited.
  • Candidates may not leave the room once testing begins.

The calculator rule matters more than it sounds. Industrial Mathematics is a full domain, so you will want a calculator you have already practiced with, and it must be non-programmable.

The 16 Exam Competency Areas

ETA's competency document lists 16 numbered categories. These are exam objectives, not a curriculum, and ETA publishes no percentage weights for them, so you cannot assume one area counts more than another. The practical conclusion: treat all 16 as examinable. For a deeper breakdown of each, see IND Exam Domains 2026: Complete Guide to All 16 Content Areas.

Domains 1-3: Safety, Industrial Mathematics, Diagrams and Schematics

These are the working vocabulary of the whole exam. Safety covers the hazards of industrial electrical work, while mathematics and diagram reading underpin nearly every later question.

  • Expect to apply formulas, not just recognize them.
  • Practice reading industrial schematics until symbols are automatic.
  • Safety questions often hide inside troubleshooting scenarios in other domains.

Domains 4-6: Electrical Components, Electro-Mechanical Devices, Wiring and Codes

This cluster covers the physical hardware of a plant: components, relays and contactors and similar devices, and the wiring practices and codes that govern installation.

  • Know how each device behaves, what it fails like, and how it appears on a diagram.
  • Wiring and codes questions reward precise knowledge of requirements rather than general familiarity.

Domains 7-8: AC Power Sources and Motors, DC Power Sources and Motors

Motors are the workhorses of industry, and the exam treats AC and DC machines as separate domains.

  • Understand construction, operating principles, and typical faults for each type.
  • Be ready to connect power-source behavior to motor performance.

Domains 9-12: Networking/Interfacing/Programming, Test Equipment and Troubleshooting, Industrial Communications, Networks

Modern plants run on data. These domains cover how devices talk to each other and how a technician diagnoses problems with instruments.

  • Test Equipment and Troubleshooting is where theory becomes method: choose the right instrument, interpret readings, isolate the fault.
  • Communications and Networks are separate headings, so study protocols and network concepts distinctly.

Domains 13-16: Fluid Power, Instrumentation, PLCs, Robotics

The final four domains cover the systems that move product and make decisions: hydraulic and pneumatic power, sensing and measurement, programmable logic controllers, and robotic systems.

  • PLC questions typically reward understanding of logic and I/O behavior over memorized syntax.
  • Fluid Power is often the domain electronics-focused candidates neglect.

The Core-Versus-Specialty Wrinkle

ETA's competency document has an internal inconsistency worth knowing about. Its introduction states that the IND Core examination covers all 16 categories, yet it also describes twelve core categories. In the body, categories 1 through 10 are labeled Core, while categories 11 through 16 are grouped into five specialty areas. No separate specialty examination is described, so the safe preparation strategy is to treat all 16 headings as fair game on the single IND exam.

Practical reading of the scope: Do not skip Domains 11-16 on the theory that they are "specialty" topics. Because the document says the IND Core examination covers all 16 categories, the lower-numbered domains are your foundation and the higher-numbered ones are still testable. Our difficulty guide discusses how this breadth shapes the challenge.

Also note the date on the source: the competency document carries a 2020 copyright. That dates the linked document, not a separately named exam version, so check ETA's current competency page before you finalize your study plan.

Eligibility and Prerequisites

Industrial Electronics is a Journeyman pathway certification, so it is not an entry-level credential. ETA's pathway requires one of two foundations:

  • The CETa credential, or
  • The complete EM1-5 foundation (ETA issues CETa when all five module certifications are current).

ETA's Journeyman pathway also says a candidate should have two or more years of experience. This is phrased as a guideline for who should attempt the credential. For the full picture, see IND Requirements 2026: Eligibility, Prerequisites & How to Qualify.

If you are earlier in your career, the sensible route is to build the foundation first and treat Industrial Electronics as the next rung. Our IND training overview outlines how candidates typically bridge that gap.

Fees, Retakes, and Remote Proctoring

The published exam fee is USD 80. A few mechanics are worth understanding before you register:

  • Free retake: One eligible exam retake is free within one year of the original session.
  • Remote proctoring: Optional ExamRoom.AI remote proctoring must be arranged through ETA and adds USD 16 for the two-hour examination. That surcharge also applies to an otherwise eligible free retake.
  • Scheduling: ETA lists test sites and course-approved schools where you can sit the exam in person.

The full cost picture also includes maintenance fees over the certification term, covered below. For a consolidated view, read IND Certification Cost 2026, and see IND Exam Dates 2026 for scheduling logistics.

Keeping the Credential Current

The certification term is four years. For credentials like IND that carry no hands-on testing requirement, ETA's general maintenance route involves:

  1. Submitting the Certification Maintenance Form.
  2. Documenting either 10 continuing-education hours per year (40 over four years) or a supervisor-completed Employer Verification.
  3. Paying USD 25 per year (USD 100 over the four-year cycle).

The employer verification option is useful for technicians already working in plants, since ongoing job duties can substitute for logging classroom-style hours. Verify the current requirements on ETA's maintenance page before each renewal period.

Who Benefits From It

Industrial Electronics is built for technicians who maintain and troubleshoot automated production environments. The domains point to the roles where it fits: maintenance technicians, controls and PLC support staff, instrumentation techs, and technicians supporting motor-driven and fluid-power equipment. Employers in manufacturing and process industries tend to value a credential that proves breadth across electrical, mechanical, and control systems in one document.

Whether the credential pays off for you depends on your employer, region, and career stage, and we do not quote figures we cannot source. For a qualitative treatment, see IND jobs, the IND salary guide, and Is the IND Certification Worth It?

Sequencing Your Preparation

With 16 unweighted domains, the main planning decision is order. One reasonable approach builds from foundations upward, because later domains reuse earlier skills. This is a sample sequence, not an official ETA schedule.

Weeks 1-2

Foundations

  • Safety, Industrial Mathematics, Diagrams and Schematics
  • Get comfortable with your non-programmable scientific calculator now
Weeks 3-4

Hardware and Power

  • Electrical Components, Electro-Mechanical Devices, Wiring and Codes
  • AC and DC Power Sources and Motors
Weeks 5-6

Data and Diagnosis

  • Networking, Interfacing, and Programming; Industrial Communications; Networks
  • Test Equipment and Troubleshooting
Weeks 7-8

Systems and Review

  • Fluid Power, Instrumentation, PLCs, Robotics
  • Full timed practice runs: 100 questions in two hours

Because the exam runs 100 questions in two hours, you have roughly a minute and a bit per question, so timed practice matters. Our IND study guide expands on this approach, and the IND cheat sheet works well as a final-week review. When you are ready to test yourself, the IND practice tests let you drill each domain and simulate the full-length exam.

Key Takeaway

Do not let the core-versus-specialty labeling tempt you to skip anything. Study all 16 areas, give extra time to Fluid Power and Robotics if your background is purely electrical, and rehearse under the two-hour clock.
