What it is

Part-time classes focused on the code books, theory and math that apprentices need to pass a state trade licensing exam. Delivered live online, in rented classroom space, or both.

Your first three steps

  1. Check your state licensing board's exam content, approved codebooks and any rules on who can provide exam prep or continuing education
  2. Build a short pilot course with a syllabus and practice questions, and test it with a few apprentices you know
  3. Reach out to local contractors, union or trade associations and supply houses to find students and referrals
Who pays

Apprentices and journeymen preparing for an exam, and sometimes their employers who cover training costs.

How it makes money

Course fees per student or per cohort, plus optional extras like practice exams, study guides or one-to-one tutoring.

Skills that help
  • Strong knowledge of one trade and its code requirements
  • Teaching and explaining technical material simply

Watch out for

  • Exam content and code editions change, so keep your materials current
  • Copyright on code books and published exam materials, so use only content you have the right to use
  • Do not guarantee pass rates, as results depend on the student
  • Business license and sales tax rules for online course sales vary by state, so check with your state revenue department
