Concerning the test scores and the possibility of transferring between companies, I have personally done this between star-company and sun company. I had passed with star-company, but wasn't going to be out in time to start for the next AO class. When asked about the POSS test, I told HR at the sun company I had a passing score with another company to which was replied "Here is this form consenting release, fill it out and have them fax us your results to validate they meet our minimum passing criteria. Then I called star-company H.R. person that had been supremely helpful while there, and she faxed over my score after ensuring that was allowed. It was allowed, score faxed from star-company to sun company, deemed good enough that I didn't have to retake, only interview. Interviewed, managed to get job, and now love it! Thanks to lots of kicks in the A help from Justin/Mike, I now have the job I wanted, at the plant I wanted to work for. This will seemingly not always work for everyone from the sounds of previous posters, however, it worked for me. Is this the recommended way? I don't know, I recognize the fact that I am just starting in this industry. Several previous posters have alluded to the fact that this isn't the norm/ or a good idea, and had I known that then, I would've just retested. YMMV, have a great thankschicken.
