For someone who finds the CSLB application process confusing and wants hand-holding, that bundled service can be worth paying for — PrepPass is exam practice only, not an application service.

Preguntas frecuentes
Do I need a $395 contractor school to pass the CSLB exam?+
No — a paid school is not required to pass. Schools like CSLS or Contractors Intelligence School bundle exam prep with help filing the CSLB application, which some first-time applicants find worthwhile. If you only need exam practice, PrepPass offers free CSLB practice with an optional $59 one-time mock. Verify current school pricing directly with each provider.
What do the contractor schools do that PrepPass doesn't?+
The schools often help you complete and file the CSLB application, verify your work experience, and navigate bonding — with phone support. PrepPass is exam practice only (question bank plus a timed mock), not an application-filing service. If the paperwork is your main worry, that bundled help is a genuine reason to consider a school.
Can I study for the CSLB exam in Chinese or Spanish?+
PrepPass offers CSLB practice in English, Chinese, Spanish and Vietnamese. Contractor schools are primarily English, though some offer Spanish. For Chinese-language CSLB study in particular, PrepPass has the broader coverage.
