IND Certification

TL;DR
  • IND is ETA International's Industrial Electronics Journeyman certification, built on 16 numbered exam-competency categories.
  • The live exam tables list USD 80, 100 questions, two hours, and a 75% passing score.
  • There is no hands-on component, and a non-programmable scientific calculator is allowed.
  • Eligibility requires CETa or the complete EM1-5 foundation, with two or more years of experience recommended.

What the Industrial Electronics (IND) Certification Is

The IND certification is the Industrial Electronics credential offered by ETA International, the Electronics Technicians Association, International. It sits at the Journeyman level of ETA's ladder of progression, which means it is designed for technicians who already have a working foundation in electronics and want to demonstrate competence in the equipment and systems found on plant floors, in manufacturing lines, and in industrial maintenance departments.

This article focuses on the credential as ETA publishes it, not on any other certification that happens to share the same three letters. If you are still sorting out the terminology, our explainers on what IND is and what IND stands for cover the naming question, while what IND certification is goes into the credential's purpose in more depth.

What sets this exam apart from many entry-level electronics credentials is its breadth. Rather than drilling into a single technology, the competency document spans safety, mathematics, schematics, components, motors, wiring codes, networking, test equipment, fluid power, instrumentation, programmable logic controllers, and robotics. It rewards the technician who has touched many kinds of industrial equipment, not the one who has memorized a single vendor's manual.

The Exam at a Glance

ETA's two live IND tables agree on the core exam parameters, and those are the figures this article follows. Here is the format in a single view:

ItemWhat ETA Lists

LevelJourneyman
Exam feeUSD 80
Questions100

Passing score75%
Hands-on assessmentNone
Certification termFour years
RetakeOne eligible retake free within one year of the original session
A note on conflicting numbers: ETA's printed certification catalog lists 75 questions for this credential, and an indexed ETA Press page shows 75 questions and a lower fee. The live IND tables on ETA's own site specify 100 questions and USD 80, so those are the figures to plan around. Before you book, confirm the current numbers with ETA directly.

A 75% passing score on 100 questions means you need roughly 75 correct answers. With two hours on the clock, you have about 72 seconds per question, which is comfortable for definition-and-recall items but tight for multi-step calculations. For a closer look at the score threshold, see our page on the IND passing score, and for the money side, the IND certification cost breakdown.

The Sixteen Competency Areas

ETA's competency document organizes the exam into 16 numbered categories. These are exam objectives taken from the published document, and ETA does not publish percentage weights for them, so you should not assume any category counts more than another. A full walkthrough lives in our complete guide to all 16 IND content areas; here is how the categories cluster in practice.

Foundations: Domains 1 through 3

Domain 1: Safety

Industrial environments combine high voltage, rotating machinery, stored energy, and pressurized systems. Expect questions that test whether you recognize hazards and respond correctly.

  • Electrical shock hazards and protective practices
  • Lockout and tagout thinking for equipment that can restart unexpectedly
  • Personal protective equipment and safe work habits around machinery

Domain 2: Industrial Mathematics

The math here is applied, not abstract. You will use it to size, convert, and verify.

  • Ohm's law and power relationships in series and parallel circuits
  • Unit conversions and working with scientific notation
  • Practice with your allowed non-programmable scientific calculator before test day

Domain 3: Diagrams and Schematics

Reading a print quickly is a daily skill for an industrial technician, and the exam reflects that.

  • Interpreting schematic symbols and ladder-style control drawings
  • Tracing signal and power paths through a diagram
  • Connecting what a drawing shows to what you would measure on the equipment

Components, Devices, and Wiring: Domains 4 through 6

Domains 4 and 5: Electrical Components and Electro-Mechanical Devices

These two areas cover the building blocks of industrial control: passive and active components on one side, and relays, contactors, solenoids, and similar devices on the other.

  • How components behave in circuits and how they fail
  • The operating principles of electro-mechanical devices that convert electrical signals into motion or switching action

Domain 6: Wiring and Codes

Installation practice and code awareness matter in any industrial setting.

  • Conductor, protection, and wiring-method fundamentals
  • Why codes exist and how they shape safe installations

Power and Motion: Domains 7 and 8

Domain 7 (AC Power Sources and Motors) and Domain 8 (DC Power Sources and Motors) are where industrial electronics separates itself from general electronics. Motors drive conveyors, pumps, fans, and machine tools, so the exam expects you to understand how they are powered, how they are controlled, and what symptoms point to trouble. Candidates who come from a pure-electronics background often find that motor theory needs extra attention.

Test, Network, and Communicate: Domains 9 through 12

Domain 9: Networking, Interfacing, and Programming

Industrial equipment rarely works in isolation, so this area covers how devices connect and exchange information.

Domain 10: Test Equipment and Troubleshooting

Because the exam has no hands-on portion, your practical judgment is tested through written scenarios.

  • Choosing the right instrument for a measurement
  • Following a logical fault-isolation sequence
  • Interpreting readings to narrow down a failed section

Domain 11 (Industrial Communications) and Domain 12 (Networks) round out the connectivity story, covering how data moves between controllers, sensors, drives, and supervisory systems.

Specialty Areas: Domains 13 through 16

The final four domains are Fluid Power (13), Instrumentation (14), PLCs, or Programmable Logic Controllers (15), and Robotics (16). Fluid power matters because hydraulic and pneumatic actuators sit alongside electrical controls in most plants. Instrumentation covers measuring and transmitting process variables. The PLC domain is often the one candidates feel most pressure about, since PLCs are the backbone of modern industrial automation. Robotics closes the list with the fundamentals of automated manipulators and their control.

Key Takeaway

Because ETA publishes no percentage weights, do not skip any of the 16 categories. A weak area in motors or fluid power can cost you as many questions as a weak area in PLCs, and you cannot predict the split in advance.

A Quirk in the Official Scope Document

If you read ETA's competency requirements closely, you will notice an inconsistency worth knowing about. The introduction says the IND Core examination covers all 16 categories, yet it also describes twelve core categories. Meanwhile, the body of the document labels categories 1 through 10 as Core and groups categories 11 through 16 into five specialty areas.

The document's date is 2020, and that date applies to the competency document itself, not to a separately named exam version. The document also includes an unnumbered Additive Manufacturing placeholder that contains no usable objectives.

The practical advice is simple: prepare for all 16 numbered categories, ignore the placeholder, and do not count on a specialty-only shortcut. If the scope matters to your employer or your plans, ask ETA to clarify before you commit to a study plan. For a candid look at how this breadth translates into difficulty, read how hard the IND exam is.

Who Qualifies for the Journeyman Pathway

IND is not an entry-level exam. ETA's Journeyman pathway requires either the CETa credential or the complete EM1-5 foundation. ETA issues CETa once all five module certifications are current, so the two routes are really the same foundation described two ways. ETA's pathway guidance also says candidates should have two or more years of experience, which is framed as an expectation for readiness rather than a separate application hurdle.

If you are earlier in your career, the sensible plan is to finish the foundation modules first and then spend a couple of years in the field before sitting for IND. Our IND requirements page walks through eligibility in more detail, and IND training covers ways to build the underlying skills.

Registration and Test-Day Mechanics

Exams are proctored through ETA Certification Administrators, using either Trapeza online testing or paper and pencil. Candidates who prefer remote delivery can use optional ExamRoom.AI remote proctoring, which must be arranged through ETA and adds USD 16 for the two-hour examination. That surcharge also applies to an otherwise eligible free retake.

  • Photo ID: required for every sitting.
  • Scratch paper: permitted, and used sheets must be returned to the proctor.
  • Calculator: a non-programmable scientific calculator is allowed.
  • Phones: prohibited in the testing area.
  • Leaving the room: candidates may not leave once testing has begun.
Plan your logistics early: Because you cannot leave the room after the exam starts, handle everything beforehand. Two hours is a long stretch, so arrive settled, and bring a calculator you already know how to use quickly. For scheduling specifics, see our guide to IND exam dates and scheduling.

A free retake is available within one year of your original session, which takes some pressure off a first attempt. Still, treat the first sitting seriously, since the retake cannot be used to simply gauge the exam.

Keeping the Credential Current

The certification term is four years. For credentials without a hands-on test, ETA's general maintenance route asks you to submit the Certification Maintenance Form and meet one of two conditions: complete 10 continuing-education hours per year (40 over the four-year term), or have your supervisor complete an Employer Verification. In either case, ETA charges USD 25 per year, or USD 100 across the full four-year cycle.

This is a lightweight maintenance burden compared with many professional credentials, which makes the long-term cost of holding IND modest. Keep a simple log of training and plant-floor learning throughout the term so the paperwork is painless.

Who Benefits from Holding It

The credential makes the most sense for people whose daily work sits close to industrial equipment. Typical profiles include:

  • Maintenance technicians in manufacturing and processing plants who troubleshoot motors, drives, and controls.
  • Electronics technicians moving from bench work into automation and production environments.
  • Controls and automation technicians who work with PLCs, instrumentation, and industrial networks.
  • Technicians who want a third-party validation of skills they already use, particularly where an employer values vendor-neutral credentials.

Whether the credential pays for itself depends on your employer, region, and role, so we avoid quoting earnings figures here. For a careful discussion, see the ROI analysis, the salary guide, and our overview of IND jobs.

Sequencing Your Preparation

You do not need an elaborate method. What helps is ordering your study so that early topics support later ones. Here is a sequence that follows the dependencies in the competency list, assuming a candidate who already holds the foundation credentials:

Week 1

Safety, Math, and Prints

  • Review Domains 1 through 3 and drill calculations with your exam calculator
  • Practice reading schematics until symbols feel automatic
Week 2

Components, Devices, and Wiring

  • Cover Domains 4 through 6 together, since they build on each other
Week 3

Motors and Power

  • Spend a full week on Domains 7 and 8, the area most likely to need extra time
Week 4

Test, Network, Communicate

  • Work through Domains 9 through 12, pairing troubleshooting practice with networking concepts
Week 5

Specialties and Full Review

  • Finish Domains 13 through 16, then take timed mixed practice sets

For a broader plan, see the IND study guide, and keep the IND cheat sheet handy for last-minute review. When you are ready to test yourself under realistic conditions, our IND practice tests let you rehearse the 100-question, two-hour pacing before the real session. You can also look at the pass rate discussion to see why we do not quote a figure here.

Frequently Asked Questions

Does the IND exam include a hands-on portion?

No. ETA's IND tables specify no hands-on assessment, so the exam is entirely written. Your practical knowledge is tested through scenario-style questions on topics such as troubleshooting and test equipment.

How many questions are on the exam and how long do I have?

The live ETA tables list 100 questions and two hours, with a 75% passing score. A printed catalog elsewhere lists 75 questions, so confirm the current format with ETA before you register.

What do I need before I can take it?

You need CETa or the complete EM1-5 foundation. ETA also says Journeyman candidates should have two or more years of experience, which is guidance on readiness.

What happens if I fail on the first try?

One eligible retake is free if taken within one year of your original session. If you used optional remote proctoring, the USD 16 surcharge applies again to the retake.

How long does the certification last, and what does renewal take?

The term is four years. Maintenance requires the Certification Maintenance Form, either 10 continuing-education hours per year or supervisor Employer Verification, and USD 25 per year in fees.
