The AP is the last step before becoming a fully fledged Police Constable.
You are on patrol with an officer however you are treated as if you are on a solo patrol.
You will need to have everything on your ODP signed off including your PRE.
Remember this is just your unofficial first patrol as a PC. Treat it as you would on a day to day patrol.
Do not be scared to attend things, you can't pass if you do nothing.
How long does the AP take?
It will take as long as it needs too. On average it is 1-3 hours, the length of a normal shift.
