I agree with klewis31975. I'm not a big fan of NNA, but I think this is one of the few things they did right. If an individual obtained a copy of any NNA certificate for anyone, they could alter the name and/or expiration date and pretend to have passed the NNA certification. Much better to get it straight from the horse's mouth. But some signing services have been reluctant to adapt to the NNA's new policy.
