CSLB Exam Fees and Retake Rules
Who you pay for the CSLB exams, when you lose your exam fee and the rules for retaking an exam you did not pass.
Quick answer
You pay CSLB a $450 application fee, then pay PSI a separate fee for each exam when you schedule it. If you fail, you can retake the exam after 21 calendar days by paying a re-examination fee to PSI. You can retake as many times as needed, but you must pass within 18 months of your application being accepted.
Who You Pay
| Fee | Paid to | When |
|---|---|---|
| Application fee: $450 | CSLB | With your application |
| Exam fee for each exam | PSI | When you schedule each exam |
| Re-examination fee | PSI | Each time you retake or reschedule after a missed exam |
| Initial license fee: $200 sole owner, $350 other entities | CSLB | After you pass |
PSI shows the current exam fee when you schedule. Check your Notice to Schedule and your PSI account for the amount.
Retake Rules
- Wait 21 calendar days after a failed attempt before retaking.
- There is no limit on attempts within your 18 month eligibility period.
- If you test within three weeks of your void date and fail, that was your last chance.
- Pay the re-examination fee to PSI and reschedule online or by phone.
When You Lose Your Exam Fee
- You do not cancel at least 48 hours before the exam
- You do not show up
- You arrive after the start time
- You do not bring acceptable identification
If Your Application Becomes Void
If you do not pass within 18 months, the application becomes void and you must submit a new application with a new $450 fee.

CSLB Exam Fees and Retake Rules: FAQs
How much is the CSLB exam fee?
The exam fee is paid to PSI, not CSLB, and each exam has its own fee. The current amount appears when you schedule through PSI.
Do I have to retake both exams if I fail one?
No. You retake only the exam you did not pass, as long as you are within your 18 month window.
Is there a limit to how many times I can retake?
No limit within 18 months, but you must wait 21 days between attempts.
