Before you test

EEI employment test batteries are designed for specific energy-industry job families, but the hiring company chooses the battery, delivery method, timing, permitted materials, scoring process, and next steps. EEI does not administer these tests directly to applicants. Confirm your assigned test and current instructions with the employer or test administrator before you study or schedule travel.
