Here's another update (in case any one is using my experience to decide if it's worth trying to fight a school for N.R.R.P.T. credits) :
1. When you send in the 'transcript request' that is on the N.R.R.P.T. website, they send out basically the same letter that they would send to a nuke plant. It says you have successfully completed the test, etc, BUT was not official enough for my director to use as a TRANSCRIPT.
2. The PONSI rep at Thomas Edison IS a good knowledge resource, but for them to actually 'transcript' your N.R.R.P.T. costs a bundle.
3. ACE will 'transcript' your N.R.R.P.T. for $35, plus $10 for each one they send to a school. This is the route I am currently pursuing. My director has 99% promised the full 30 credits as soon as ACE sends the transcript!
