What's on This Practice Exam

Preparing for the Tennessee Electrical Contractor continuing education exam takes more than reviewing the codebook — you need to practice answering questions the way they're actually asked. This page gives you two ways to do that.

Free practice exam: Get 10 questions per attempt drawn from a limited question pool. You can retake it as many times as you want, making it a great way to sample the question style, check your baseline knowledge, and decide where to focus your study time.

Full practice exam: Built to mirror the real exam experience — 100 questions, a 300-minute time limit, and a pool of 578+ practice questions so every attempt generates a fresh, unique set. You'll never see a duplicate exam, which means repeated attempts continue to build new knowledge rather than just reinforcing memorized answers. Every question is based on the official exam topics provided by the Tennessee licensing authority.

The real exam requires a 73% passing score, so knowing where you stand before test day matters. Both options give you immediate scoring so you can gauge your readiness right away.

How This Practice Exam Helps

Passing a licensing exam at the 73% threshold requires both knowledge and confidence under time pressure. The full practice exam puts you in realistic conditions — 100 questions, a timed 300-minute session, and a topic distribution that reflects the actual exam blueprint.

After each attempt, you'll see your score broken down by topic area, so you can instantly identify whether you need more work on Grounding and Bonding or Hazardous Locations rather than guessing where your gaps are. Because the full exam draws from 578+ questions and never repeats a session, you can take it multiple times and face genuinely new questions each time — making each attempt a productive study session, not just a memory exercise.

Start with the free exam to get comfortable with the format. When you're ready to prepare seriously, the full practice exam gives you the depth and variety you need to walk into the real test with confidence.
