The results of the parents will show on the puppies registration certificates. IT is true that the system at the moment requires testing but not passes (which many of us find ridiculous) but as far as I am aware they will not accept litter registrations if the testing has not been done - a friend registered a litter last year and had a phone call back almost straight away saying the eye tests were out of date so the registration could not go ahead - this was an instance of the Vet taking ages to send them is, so she had to post her copies so the registration could go through in time for the paperwork to be ready to go with the pups. I suppose it depends on how vigilant the person doing the paperwork at the KC is.
OF course, this only applies to a breed with health testing required.
