Tom,
<<<The "certification" is a fairly strict and precise term. It depends on who is at the facility, watching the test, handling material, etc. to actually qualify as "certified". Unbiased verification of a process is the goal.>>>
Actually, certification depends more on which state the assay is being performed in. In New Mexico there are no requirements for assayers. Anybody can open a lab in their garage and do assays. They can certify the assay results but do not have any official authority other than their word.
In Arizona, assayers have to be registered. When they certify results they have a seal issued by the State with which they may seal their certification. However, being registered with the state does not guarantee competence.
I am not sure about CA, NV, or UT. I did a white pages search, yellow pages search, and looked through several supplier guides for the mining industry and I can find no NWA other than the one I mentioned before. Without knowing where the lab is located and who the assayer is, there is no way to ascertain if the lab can even certify other than by their own word.
