The aptitude test is developed and scored under the standards of the Electrical Training Alliance. It consists of algebra and reading comprehension. Applicants are scored on a scale of 1-9. A score of four (4) or higher will qualify for a interview. If a score is below four (4), a applicant will need to wait 3 months and submitt a new application with all the required information for re-testing. You can not retest within the first 3 months after taking a test.
When a applicant submits his application, the application is assigned to the next testing date. Testing is conducted monthly. The sooner a application is submitted, the sooner a testing date will be scheduled. When a testing date is scheduled, the applicant will be notified by mail of the testing date.
