You may reactivate the certificate by taking the Competency Evaluation if your certificate has not been expired for more than two (2) years, and you did not meet the renewal requirement. 

To reactivate the CNA certificate, please submit the completed Renewal Application (CDPH 283C), making sure to check the “yes" box for question number six (6) in the “Reactivation" section.  If approved, a Competency Evaluation approval letter will be sent to you, along with information needed to schedule the examination.  You must complete the evaluation within two (2) years from your certificates expiration date. 

Once you have successfully passed the examination, maintained criminal record clearance, and the results from the testing vendor have been received, CDPH will issue a current CNA certificate.​
