hia mate not yet am working from the bottom to the top mate as i feel that its the only way forward for us civi types as we dont have the years of experience behind us to go cpo straight away, not beeing horrible mate but i carnt really see you getting a cp job just by doing 2 to 4 weeks on a course read what ervyone else says here mate unless you are x army or police its almost impossible that why i am working up the tree to see if i have a better chance that way.
Good luck mate whatever you do through
Keep Safe
