I just heard on sky news that as part of the white paper screening for security personnel will go to yearly
Matt, I believe they mean the competency assessment that is currently undertaken at the start of employment as a security screener. This was a post 9/11 initiative that was supposed to ensure that security staff are capable of reading an X ray correctly, but under the current system the test is not repeated regularly, ie you might have passed the 'hand granade: yes or no' test back in 2002 but no-one's checked since.
I haven't had the strength or time to read the whole thing yet, so I'm happy to be corrected.
