Approved by

American
National
Standard
Approval of an American National Standard requires verification by
ANSI that the requirements for due process, consensus, and other
criteria for approval have been met by the standards developer.
Consensus is established when, in the judgment of the ANSI Board of
Standards Review, substantial agreement has been reached by directly
and materially affected interests. Substantial agreement means much
more than a simple majority, but not necessarily unanimity. Consensus
requires that all views and objections be considered, and that a concerted
effort be made toward their resolution.
The use of American National Standards is completely voluntary; their
existence does not in any respect preclude anyone, whether he has
approved the standards or not, from manufacturing, marketing,
purchasing, or using products, processes, or procedures not conforming
to the standards.
The American National Standards Institute does not develop standards
and will in no circumstances give an interpretation of any American
National Standard in the name of the American National Standards
Institute. Requests for interpretations should be addressed to the
secretariat or sponsor whose name appears on the title page of this
standard.
Caution Notice: This American National Standard may be revised or
withdrawn at any time. The procedures of the American National
Standards Institute require that action be taken periodically to reaffirm,
revise, or withdraw this standard. Purchasers of American National
Standards may receive current information on all standards by calling or
writing the American National Standards Institute.

FOREWORD
(This Foreword is not part of American National Standard ANSI/NETA ETT-2010)
The InterNational Electrical Testing Association (NETA) was established in 1972 to establish uniform
testing procedures for electrical equipment and apparatus. NETA developed specifications for the
acceptance of new electrical apparatus prior to energization, the ANSI/NETA Standard for Acceptance
Testing Specifications for Electrical Power Equipment and Systems, and for the maintenance of existing
apparatus to determine its suitability to remain in service, the ANSI/NETA Standard for Maintenance
Testing Specifications for Electrical Power Distribution Equipment and Systems.
In 1987, NETA recognized the need to establish a standard for technicians who perform electrical
testing services. The Preface of Standard for Certification of Electrical Testing Technicians succinctly
states the necessity of this document.
This standard was created to codify the experience, education, and training requirements necessary for
an individual to obtain a level of competency as an electrical test technician. NETA carefully examines
the qualifications of each NETA Accredited Company (NAC) in addition to certifying the individual
technician employed by that NAC. Because of this requirement, another directive of this task group was
to assure that the NETA requirements for certification were aligned with an alternate certification path
for qualified individuals.
The participation of a wide variety of stakeholders during the review process contributed to the creation
and acceptance of this document as an American National Standard.
ANSI/NETA Standard for the Certification of Electrical Testing Technicians was approved as an
American National Standard by ANSI on March 15, 2000. On January 8, 2010 ANSI/NETA ETT-2010
was approved as a revised American National Standard.
Suggestions for improvement of the standard are welcome. They should be sent to the InterNational
Electrical Testing Association, 3050 Old Centre Avenue, Suite 102, Portage, MI 49024.

ANSI/NETA ETT-2010
Standard for Certification of Electrical Testing Technicians
PREFACE
Specifying requisite levels of training, experience, and education for the evaluator of electrical power
equipment is as important as the test procedure itself. The requirements herein parallel those of the
National Skill Standards Board in Washington, DC, which promulgates skill levels for various
occupations.
An Electrical Testing Technician (ETT) performs tests and inspections and evaluates the suitability of
electrical power equipment and systems for the intended use.
Inherent in the determination of the serviceability of electrical equipment is the prerequisite that
individuals performing these tests be capable of conducting the tests in a safe manner and with complete
knowledge of the hazards involved. They must also evaluate the test data and make an assessment on the
continued serviceability or nonserviceability of the specific equipment. The evaluation of service-aged
equipment requires subjective assessment by the ETT.
Certification is a means for individuals to indicate to employers, co-workers, the general public, and
others that they have met the standards of an impartial, nationally-recognized organization for the
performance of specific technical tasks by virtue of their technical knowledge and experience.

Certification bodies meeting criteria
Known certification bodies in the United States which meet the criteria set forth in this
standard are the InterNational Electrical Testing Association (NETA) and the Electrical
Test Technician Certification Institute (ETTCI).
7.13.1
InterNational Electrical Testing Association (NETA)
The InterNational Electrical Testing Association has provided an independent,
third-party certification program since 1975. It is a proven program based on
accepted academic principles. By requiring membership and certification of the
company as well as the individual, NETA enhances the industry and protects the
consuming public by enforcing such requirements as calibration programs, safety
programs, self-review programs, ethical practices, etc
7.13.2
Electrical Test Technician Certification Institute (ETTCI)
ETTCI was founded to address the need for a certification path for qualified
individuals seeking recognition as Electrical Testing Technicians. ETTCI’s
application process and certification examinations were developed in accordance
with structure and guidelines outlined in the ANSI/NETA Standard for
Certification of Electrical Testing Technicians.
7.14
Self-Certification Programs
Self-certification programs do not meet the criteria set forth in this standard since an
organization providing self-certification has a significant financial stake in the outcome of
the certification process. Self-certification does not provide independent, third-party
objectivity.
