What is the EEI test?
Also known as the Edison Electric Institute test, EEI tests are a series of tests that are developed to measure if a candidate possesses skills and abilities that are relevant to the energy industry. These tests help to determine if the skill set that an individual possesses can lead to job success in the industry.
EEI tests are created and maintained by the Edison Electric Institute, which has served as the representational body for privately owned and investor-electric companies in the U.S since 1933. EEI tests are specially tailored to measure skills such as problem-solving, math, spatial awareness, administrative, and technical and mechanical comprehension.
EEI test series is comprised of nine different tests that measure basic capabilities, strengths that are vital to succeeding in a certain role, as well as general industry knowledge. Candidates are not required to sit all nine tests. Instead, employers give them the test that is the closest match for the position they have applied for.
When you get invited to take an EEI test, your employer will most likely refer you to the EEI website for sample test material. However, this material will only provide you with a partial picture of what the test looks like, and they do not match the real test’s level of difficulty. Additionally, the sample tests are not timed, while the real test has strict time limits.
