While running a contractor license school, I learned that the biggest difficulty my students faced was that most of them had not taken an exam in years.

  • Some of my students did not finish high school or had immigrated to the United States recently, and were still learning English. 

  • One of the best study tools for them was to use Online Practice Tests. Simulated online tests are based on the state exam. 

  • Unless you went to a welding school or achieved some level of certification, it is possible that taking tests may be new to you

3. How helpful are exam prep study guides for the contractor license test?

Test questions are great, but relying on them as your only study source is a big mistake. If you are not into reading, you can find C-51 license exam study books in audio or video format.

Since practice test questions for the welding license exam do not give you the theory behind what the questions are asking you. 


Using a book or study guide as a reference can be a big help.

Exam prep books for the welding license cover a wide range of topics. They can also be incredibly helpful to refresh your memory on core topics you may have forgotten.

Free contractor license study guides often cover just a snapshot of what you need to know. 

Invest in yourself and look for study guides that cover topics like:

  • Shop preparation
  • Field preparation
  • Finishing
  • Mobilization
  • Plans and specifications
  • Bidding and job cost estimating
  • Placing
  • Connecting

4. Contractor Schools

When you see the term “Contractor Classes” you should understand that they are only LAW & BUSINESS classes for construction contractors.

Contractor license schools offer state-specific exam prep classes that cover the basics of construction LAW.

It is essential to understand the distinction between a contractor license and a trade school. The C-51 license test is for journeymen. A journeyman is someone who has mastery of their trade.

Contractor classes are not meant to teach you the fundamentals of steel fabrication.

They are highly beneficial for those of us who haven’t been in school for a while.

Contractor License schools offer several services that can help you get everything taken care of quickly and easily.
