What the class is and is not

You receive a certificate of completion. It is not a contractor license, not a manufacturer certification, and not a warranty program. Licensing rules depend on your state; in California, jobs over $1,000 in labor and materials require a CSLB license.

Numbers shown on this site, including the job calculator, are examples based on inputs you choose. They are not a promise of income.
