Verifying Work Experience: After meeting the basic eligibility requirements, the qualifier could be randomly selected to provide documentation that they meet the minimum work experience requirements. Having this documentation ready beforehand can make this process easier if your application is selected for review. The experience listed on the application must be verifiable, and people with firsthand knowledge of that experience must certify the accuracy of the information provided to CSLB on the Certification of Work Experience form.
  3. Complete Application: Must fill out the Original Contractor, Additional Classification, or Replacing the Qualifying Individual application form.
  4. Submit Application and Required Fees: For the current list of fees visit the California CSLB Fees page .
  5. Fingerprint Requirement after CSLB Review of Application: For information on fingerprinting, visit the CSLB Fingerprinting Requirement page.
  6. Schedule the Exams: Once the application is submitted the CSLB will send you a 'Notice to Appear for Examination." Upon receipt, the business exam and a Solar (C-46) exams must be scheduled and passed.
  7. Contractor Bond: All applicants must submit to CSLB a contractor bond or cash deposit payable to CSLB in the amount of $15,000. CSLB does not issue bonds.
