* The CUI Mandatory Training Course is the official initial CUI training course and also meets the annual refresher training requirement.  

Certificates:  There is a test at the end of the CDSE mandatory training course.  When you finish the test, you have the opportunity to create and print a certificate.  If you take the training through a learning management system, you should receive a certificate.  If you have any problems with getting a certificate, please talk to your training manager.  There is no certificate if you take the training through the Security Awareness Hub.
