SC189 application

Hello, I would like to ask what the PCC stands for, while loging the 189 PR application. This is because that I saw a lot of persons mentioned the PCC material while doing the 189 application.
It is Police clearance certificate. Thanks

If so can someone share some insights and also, the medicals has been completed as "No Action required", do I need to upload something to prove this as a document ? Please advice guys,
