Returning to CRST after 3 years

I went through training with CRST in the Winter of 2005 and completed its then 6 month driving obligation. I then left the company, lost my Class A license and went into another field of work for a few years. In the meantime, CRST sent me a nice certificate stating I had completed their program, etc. If I wanted to go back and work for them, would I have to start again from the beginning?

 

At the end of the 6 months with CRST, the DMV wanted me to do another test for them because there was some problem with CRST's training standards. I decided I was going to pursue other career options so I didn't bother. A few weeks later I get a letter from DMV stating my Class A license was revoked which was fine by me at the time. I have no probs going out with a trainer and doing a refresher course but I'd like to know if I have to repeat the whole process over again from the start and sign the dreaded contract.
