Short answer: You learn in two places at once. In class you study subjects such as electrical theory, print reading, grounding, controls, testing equipment, conduit bending and the National Electrical Code; that is the curriculum Houston JATC lists. On the job you learn by working under experienced journeyman electricians, from digging trenches, carrying conduit and pulling cable to wiring lights and receptacles and finding out why a motor will not start. Federal rules (29 CFR 29.5) require each registered program to write down the work processes you will be trained in and about how much time goes to each one, plus safety training on the job and in class.
Preparing to apply for an electrical apprenticeship? The Texas Electrical Apprenticeship Entry Kit is for getting in, not for job site skills. It has 1,366 math and 288 reading aptitude-test questions with worked answers and 8 timed simulations, plus 20 interview questions with a weak and a strong answer for each, an 8-question mock interview, a 7-day start plan, and 13 Texas apprenticeship programs checked on their own websites. Launch price US$49 through November 30, 2026, one payment, instant download.
Tsai Electro is an independent learning site. Not affiliated with TDLR or any apprenticeship program. Each program sets its own course order, so ask for its outline.
Classroom and job site, side by side
| In class | On the job site |
|---|---|
| Electrical theory | Understanding why a circuit behaves as it does while you help run conduit and pull wire |
| Print reading | Using the drawings to find where equipment and runs go |
| Grounding | Installing grounding and bonding as directed |
| Controls | Learning how motor controls work, then helping troubleshoot when trained and authorized |
| Testing equipment | Using meters under a journeyman’s supervision |
| Conduit bending | Handling and bending conduit of many sizes |
| The National Electrical Code | Finding the code rules that apply and following approved installation instructions under supervision |
Houston JATC says the program covers residential, commercial and industrial installations, and that the work is often physical: mud and dust, all kinds of weather, ladders, heavy cable and cleanup. Its instructors are mostly working electricians or managers at electrical companies.
How ready are you for day one?
Day-one familiarity check
Check the skills and working conditions you already feel familiar with. This is a self-check, not an entrance test or a safety qualification; your employer and instructors teach you how to work safely.
- I can work outside in heat, cold and rain for a full day
- I can carry heavy material and climb an extension ladder safely
- I can read a tape measure to the sixteenth of an inch
- I can do fractions, decimals and basic algebra without a calculator
- I know the difference between voltage, current and resistance
- I can read a simple floor plan
- I can name common hand tools such as strippers, linesman pliers and a level
- I follow safety rules even when others cut corners
What the first years look like
- Year one tasks are covered in the first year of a Texas apprentice electrician.
- Later years add more of the work itself, more responsibility and more theory, as listed in your program’s work process schedule. See year two of a Texas apprentice electrician.
- By the end you may have the experience the TDLR Journeyman license asks for: 8,000 hours of on-the-job training under a Texas Master Electrician plus a passing exam, with the option to apply after 7,000 hours to test early. Finishing an apprenticeship does not by itself grant the license.
Ask your program for its work process schedule. It is the list of what you should be trained in on the job, and it helps you speak up if you have been doing only one task for months.
What do you learn in an electrical apprenticeship?
Classroom subjects such as electrical theory, print reading, grounding, controls, testing equipment, conduit bending and the National Electrical Code, plus job site skills learned under journeyman electricians. That is the Houston JATC curriculum; other programs cover similar ground.
Do apprentices learn the same skills in every program?
Not exactly. Houston JATC lists electrical theory, print reading, grounding, controls, testing equipment, pipebending and the NEC. Other programs may order subjects and job site training differently, so ask each program for its curriculum and work process schedule.
Do apprenticeships include safety training?
Yes. Federal rules for registered programs require safety training on the job and in related instruction.
