What to know now.
California uses the title Certified Nurse Assistant (CNA) certificate. The initial certificate is issued for two birthdays and expires on the holder's birthday; after that, timely renewals follow a two-year cycle. Current CDPH guidance requires 48 total hours of in-service training or continuing education during the two-year certification period, with at least 12 hours in each year and no more than 24 hours completed through an approved online program. CDPH also requires qualifying paid, supervised patient-care work during the certification period. OASYS now supports online renewal submissions and document uploads.

Verified facts
Use the official source for the final check.
- Credential and cycle: California issues a CNA certificate. The initial certificate spans two birthdays; timely renewals then follow a two-year cycle.
- Training/CE requirement: CDPH currently requires 48 hours of in-service training or CEUs during the two-year certification period, with at least 12 hours in each year.
- Online-hour limit: Up to 24 of the 48 hours may be completed through a CDPH-approved online program.
- Work requirement: Current CDPH guidance requires at least one day of paid direct patient-care work under licensed supervision during the certification period.
- Online renewal: CDPH's OASYS process allows electronic renewal submission and uploading of CEU, employment-verification, and deficiency documents.
- Expired certificate: CDPH has separate reactivation rules for expired or otherwise nonqualifying certificates; do not assume a normal renewal workflow applies after expiration.
Renewal workflow
Turn the requirement into a repeatable checklist.
- Step 1
Verify the CNA certificate's current expiration date in the California Department of Public Health record.
- Step 2
Track the 48-hour training/CE requirement across both years instead of waiting until the final weeks of the certification period.
- Step 3
Keep the employment verification needed to show qualifying paid supervised patient-care work during the certification period.
- Step 4
Submit the current CDPH renewal application and supporting documents through the accepted online or mail process before expiration.
- Step 5
After CDPH issues the renewed certificate, record the new expiration date and begin the next two-year tracking cycle.
From one credential to a tracking system
One renewal question can reveal a much larger roster problem.
If you are responsible for several employees, contractors, or credentials, the hard part is often no longer finding one renewal rule. It is keeping every holder, authoritative date, reminder, completion, and renewed date visible without repeatedly scanning a spreadsheet.
Care-workforce rosters can be especially mixed: CNA or nurse-aide records, HHA/HCA/CHHA credentials, RN/LPN licenses, CPR/BLS, and other recurring requirements may all sit under one administrator.
