2. Take C-42 License Practice Tests
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.
Practice Test Questions
1. Which public agency issues permits for vacuum trucks?
a. California Department of Transportation

d. Department of Public Health
3. How does clay soil affect the surface area of seepage pits?
a. The size of the pits will need to be smaller.
b. Imported soil might be used to install the pits.

3. Use Contractor License Study Guides
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-42 sanitation license exam study books in audio or video format.
Practice test questions for the sanitation license exam do not give you the theory behind what the question is asking you. Use a book or study guide as a reference.
Exam prep books for the sanitation 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.

4. Contractor Classes
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-42 license test is for journey level tradesman who has a solid understanding of the sanitation systems trade. Contractor classes are not meant to teach you your trade.
