All NAVHDA test scores are listed on the NAVHDA pedigree.
However, like AKC, there are no enforced standards for breeding, but the community is much smaller which makes it much more difficult to cheat the system. AKC is so big and political that it has become more about helping the AKC and less about helping the dog breeds themselves. I have seen more than one case where DNA samples taken from pups did not match the parents on the pedigree and nothing is done to penalize this. I don't believe this kind of thing could happen at NAVHDA; not because the system couldn't be tricked; but because the community is small and dedicated enough that it wouldn't tolerate such behavior.
Also there is far more emphasis by NAVHDA breeders to only breed dogs that have successfully completed tests than in AKC. Personally, I am happy that AKC doesn't recognize NAVHDA test scores. AKC is an everything for everybody type organization. NAVHDA caters only to hunters.
There are great dogs in both systems, but I would argue the level of consistency is substantially higher in pups whelped by a NAVHDA breeder than an AKC breeder.
