For professionals working in manufacturing, automation, and robotics, demonstrating technical proficiency is the key to career advancement. The ETA International Industrial Electronics (IND) certification stands as one of the most respected credentials in the field. This guide provides a comprehensive breakdown of everything you need to know to earn this prestigious “Journeyman” level certification.

What is the ETA International Industrial Electronics (IND)?

The Industrial Electronics (IND) certification is a specialized credential designed to validate the skills of technicians who install, maintain, and repair electronic equipment used in industrial settings.

  • Official Exam Name & Acronym: Industrial Electronics (IND)
  • Conducting Body/Authority: Electronics Technicians Association, International (ETA-I). Founded in 1978 by electronics teachers and technicians, ETA-I is a professional association that has issued over 200,000 certifications globally.
  • Purpose of Exam: Professional Certification. It serves to provide an objective measure of a technician’s knowledge in industrial systems, including power supplies, PLCs, and motor controls.
  • Geographic Validity: Globally recognized. ETA-I certifications are accredited by the International Certification Accreditation Council (ICAC) and are widely accepted across the United States, Canada, and by international defense and automation firms.
  • Level of Competence: Specialist/Journeyman Level. This is not an entry-level exam; it demonstrates that the holder has mastered advanced industrial concepts beyond basic electronics.
  • Brief History: Established to bridge the gap between general electronics repair and the highly specialized needs of the manufacturing sector, the IND exam has evolved from focusing on vacuum tubes and relays to modern microprocessors and automated logic controllers.

Who Can Take the ETA International Industrial Electronics (IND)? (Eligibility Requirements)

The IND is considered a “Journeyman” level certification. To hold the full IND credential, candidates must meet specific foundational requirements.

Eligibility Checklist

  • Academic Requirements: No specific degree is mandated, but a High School Diploma or equivalent is expected. Most successful candidates hold an Associate Degree in Electronics Technology or Industrial Automation.
  • Experience Requirements: Candidates must have at least two years of documented experience in the electronics field or have completed a formal electronics training program.
  • The Prerequisite Rule: To receive the Industrial Electronics (IND) Journeyman certification, you must also pass the ETA Associate Electronics Technician (CETa) exam. You can take the IND exam before the CETa, but the certification will not be issued until both are passed.
  • Documentation Checklist:
    • Valid Government-issued Photo ID (Passport or Driver’s License).
    • Proof of work experience (if not using the education track).
    • ETA-I Membership Number (optional but reduces fees).
  • Language Proficiency: The exam is primarily administered in English. While no formal TOEFL score is required, a high-school level of English reading comprehension is necessary.
