Ah well, paperwork being copies of your proof of residence, copies of high school results, pilots licence or tertiary education, and a stat dec we had to bring as well, which was linked to in the email we got confirming our booking for the testing day. All easy stuff, but one guy on my day still managed to not bring half of it signed and copied like he was asked :P
Pretty sure the ability to follow simple instructions is a valued quality in a potential ATC recruit :P
