Certified Electric Vehicle Technician Standards - 2023

Introduction 

Design of the Certified Electric Vehicle Technician Standards 

The Certified Electric Vehicle Technician Standards define the knowledge and skills that need to be effectively taught and learned for all learners to be literate in electric vehicle foundations. Learners who have this literacy are ready to succeed in technical schools, in the workplace, in military service, and engage in civic responsibilities related to electric vehicles. These standards present a vision of what it means to be scientifically and practically literate in electric vehicle foundations. 

Standards Validation Committee

The Electric Vehicle Safety Council (EVSC) developed and validated these standards on 7/25/23

Core Concepts

Core Concepts

The Certified Electric Vehicle Technician Standards focus on fifteen core concepts in EV understanding and practice, adapted from the Next Generation Science Standards, the Arizona Department of Education Science Standards, the Arizona Department of Education Career and Technical Standards for Automotive Technologies, and the ASE Education Foundation Automobile Program Standards. Seven Core Ideas for Knowing an EV center on understanding how and why the interrelated systems of an electric vehicle perform and function in tandem. Then, eight Core Skills for Working with EVs connect higher levels of practical application to the foundations of electric vehicle knowledge, diagnosis, scientific principles, theories, & models; engineering and technological applications; and societal implications to support the EV industry.

The standards are neither curriculum nor instructional practices

While the Certified Electric Vehicle Technician Standards serve as a basis for a curriculum, they are not curriculum. Therefore, identifying one’s own sequence of instruction requires concerted effort and attention at the local level of which it is being taught. The Electric Vehicle Technician Education Council defines standards, curriculum, and instruction as: 

  • Standards are what a learner needs to understand and be able to do by the end of the program. Standards build across the training in a progression of increasing understanding and application and through a range of cognitive demand levels.
  • Curriculum refers to the resources used for teaching and learning the standards. Curricula are adopted at the local level. 
  • Instruction is defined as the methodologies used by trainers to train learners. Instructional design and techniques are executed by individual educators in response to the needs of their learners to help them progress through the curriculum to master the standards. Instructional design and techniques are decided at a local level.

This framework does not explicitly adhere to the needs of learners with no automotive and/or electrical foundations or others who are far below the National Assessment of Adult Literacy (NAAL). 

No set of standards can truly reflect the variety in achievement levels, abilities, and needs of all learners. The Certified Electric Vehicle Technician Standards do not outline methods for intervention to support learners who are far below the National Assessment of Adult Literacy (NAAL) or do not speak English as their first language. See APPENDIX B for strategies to support equity, diversity, inclusion, and accessibility in technical education. 

Safety Expectations 

The concern for safety, particularly high voltage and battery chemistry safety, is of utmost importance in the learning environment. Each standard and application of knowledge has the following safety requirements preceding all related tasks: 

  • Comply with personal and environmental safety practices associated with clothing; eyewear; hand tools; power equipment; ventilation systems; and the handling; storage; and disposal of chemical/materials in accordance with local, state, and federal safety and environmental regulations. 
  • Comply with local, state, federal, and international standards related to high voltage health and safety regulations, including, but not limited to, the standards outlined by the United States Department of Labor’s Occupational Safety and Health Administration (OSHA), the National Highway Traffic Safety Administration (NHTSA), the Department of Transportation (DOT), and the Global Technical Regulation (GTR). 

Coding of the Technician Standards

Each Certified Electric Vehicle Technician Standard represents the intersection of Core Ideas for Knowing an EV and Core Skills for Working with EVs. This intersection emphasizes that content related to Knowing an EV is not learned independently from skills for Working with EVs, theoretical applications, or other practical skills-based knowledge. Learners will engage in theoretical understanding as they gather information to solve EV problems, answer their own questions, interpret EV data, use practical evidence to support their understanding, and then communicate those findings to others, including potential customers. The standard numbers are for documentation purposes and do not imply instructional sequence or importance. Below are examples of the standard coding sequence.
