You must also have:
Journeyman level experience means that you have worked unsupervised full time for an electrical company, or contractor that holds the C-55 License.
The CSLB will want to see four full-time years over the last ten years. The years do not need to be consecutive, but they do need to be four years in total.
Signature of a Qualifying Individual
The following people may be used as Qualifying Individuals to sign off on your experience when applying for the C-55 license:
Your Qualifying Individual will also need to provide a brief but detailed description of your knowledge and skillset.
The way this description is written will be critical to whether or not your application is accepted. For example:
“Ed installed our water filter” is not descriptive enough.
The CSLB will want to see:
"Ed has safely connected treatment systems to existing water supply, conducted water analysis, installed pipes, vales and installed water conditioning equipment".
The description written by your qualifying individual will need to include the core skills required a water conditioning contractor.
You must be prepared to submit documentation supporting the experience you claim to have. The Contractors State License Board gives you a few ways that you can prove your experience.
The CSLB receives thousands of applications per month so there is a good chance they won’t document your experience.

The truth is many applicants with criminal records get licensed in California each year...some end up obtaining multiple classifications.
The key is to be honest on the application, even if the felony or misdemeanor happened years ago and even if it was expunged.
BE 100% HONEST ON THE APPLICATION, because they will see everything anyway when you do fingerprinting. The CSLB handles criminal records on a case by case basis.
Remember, their responsibility is to protect the public.
