A minimum of 1500 on-the-job hours must be documented. Once a task has been successfully demonstrated in the service center, the student and the student's supervisor/mentor will initial and date the task. As each page is completed, a member of top management must sign and date the checklist.
Any portion of the checklist may be completed based on work performed and competencies demonstrated prior to enrolling in the program.
IMPORTANT: It is the responsibility of the student's employer to monitor the student's progress and to make the determination when a student has displayed adequate proficiency for each checklist criteria point.
Due to the vast range of service center sizes, capabilities, types of work performed, and tools available, EASA is unable to provide detailed checklist criteria to cover every possible instance. It is the responsibility of the employer to ensure the student has sufficient knowledge and skill to safely complete each checklist item.
In this phase of the program, the student will learn more advanced skills that can be applied to their on-the-job training and tasks within the checklist.

Introduction to ANSI/EASA AR100
Duration: 1 hour
Course format: Slide-based video presentation with quiz.
This lesson provides an overview of the industry's guide for the repair of electric motors: ANSI/EASA AR100: Recommended Practice for the Repair of Rotating Electrical Apparatus.
The scope of this document describes record keeping, tests, analysis and general guidelines for the repair of induction, synchronous and direct current rotating electrical apparatus. It is not intended to take the place of the customer's or the machine manufacturer's specific instructions or specifications or specific accepted and applicable industry standards or recommended practices.
ANSI recognizes only one standard on a topic; therefore, the EASA Recommended Practice is the standard for repair of rotating electrical apparatus.
Introduction to the EASA/AEMT Good Practice Guide to Maintain Motor Efficiency
Duration: 45 minutes
Course format: Slide-based video presentation with quiz.
This lesson provides an overview of repair/rewind practices and tips that will help service center technicians and motor winders maintain or increase the efficiency, reliability and quality of the motors they repair.
Some of the included procedures included derive directly from the 2019 and 2003 rewind studies by EASA and AEMT of the impact of repair/rewinding on motor efficiency. Others are based on the findings of an earlier AEMT study [1998] of small/ medium size three-phase induction motors and well-established industry good practices .
The procedures in this guide cover all three-phase, random-wound induction motors. Much of the guide also applies to form-wound stators of similar sizes.
(Note: This guide provides many specific procedures and recommendations. Alternative practices may accomplish the same results but must be verified.)
Once all activities on the checklist have been completed and signed by the student's supervisor(s)/mentor(s), the student will upload the checklist through an activity in the ERT course within the EASA Learning Center. EASA's Technical Support Specialists will then review the checklist and approve it or send it back to the student with comments to be addressed. If necessary, EASA staff may contact your mentor(s)/supervisor(s) for verification of the completed tasks.
Once approved (and if all required coursework is complete), the Electromechanical Repair Technician Certificate will be unlocked and will be available for download and printing. A printed copy of the certificate will also be mailed to the student.
EASA will recognize ERT Certificate awardees online and at the annual convention. The online company profile will also display a count of employees that have earned the ERT Certificate.
