Whilst r75 is right about experience sheets and recording work - I refer you back to Post No. 10 para 2.
I hit this problem with a Workshop mechanic who was recommended for an approval but I couldn't give him one (in that company) due to the lack of "certified" basic training or any other relevant qualification.
Different companies may view this in different ways - but its one that may stop you from joining anywhere.
Strangely, the answer may be for you to go through all the modules, prove you know what you're on about, and get yourself an EASA Licence!!
