Electrician Assessment
A 34-question assessment with a 45-minute timer will start on the first question.
Before you begin...
(Required)
Close any unnecessary applications and check that you have a stable network connection. If you lose connection, you can't continue your assessment where you left off.
Please don't use reference materials, take notes or accept any outside help while working through your assessment, as you may be breaking the law by doing so.
We need your consent for the test administrator to record your name and email address and store these details and test results in our database. The test results will belong to them, and it's up to them how they will share the results with you.
