Hi Seal,
Your practice Information Governance (IG) toolkit has loads on confidentiality as this is what it is basically about.
If you search IG online you should find loads, there are recommended and mandatory tests for you to do, we've been classing them as verifiable as they have set out what you should learn, have a time frame that it should take you, you're tested on your knowledge and it's all saved online.
You practice should know about this..
Hope that helps you x
