Technician Certification
As part of its commitment to advancing professionalism within the onsite power industry, EGSA offers the Electrical Generator Systems Technician Certification Assessment. This rigorous assessment identifies technicians who possess comprehensive knowledge of electrical systems, mechanical and electrical components, and their interactions, as well as the processes and procedures required for the installation, service, maintenance, and repair of onsite power generation systems.
EGSA’s Technician Certification is available at two levels:
- Apprentice Certification – Designed for technical college students, recent graduates, military personnel, and first- or second-year technicians, this exam covers 40+ areas of expertise and validates that fundamental knowledge of onsite power systems have been achieved. Certification is valid for three years.
- Journeyman Certification – Intended for technicians with at least three years of practical field experience, this exam covers 61 individual areas of expertise, assuring employers that the technician meets or exceeds industry knowledge standards. Certification is valid for five years.

Test Preparation
EGSA currently has two options to help you prepare for the Apprentice and Journeyman Certification exams: study guides and EGSA Prep+.
Study Guides:
The EGSA study guides are practice booklets that are mailed directly to you. These study guides are a great option for technicians who have experience but just want to know what to expect on test day. The booklets include all the knowledge areas included in each assessment and practice questions to help candidates gauge their readiness.
Study guide booklets can be ordered by visiting the EGSA Store.
EGSA Prep +
This instructor-guided review program is offered both in-person and in live online formats. The review session has the highest success rate of all EGSA preparatory offerings, and it includes a review of all main test topics to ensure that technicians are fully prepared for the Apprentice and Journeyman Certification exams. The course is offered as one 4-hour review and can include both apprentice and journeyman candidates simultaneously. There are no prerequisites for EGSA Prep Plus but completing the study guide and purchasing EGSA’s Onsite Power Generation reference book are highly recommended.
