In the old East Germany the Schutzhund and working dogs were rated by the Wertmessziffer system. In English Wertmessziffer means "measured value number". This system was quick and easy to understand for breeders/buyers wanting to get a look into the conformation and temperament of any dog that had been evaluated and rated.
As an example, a dog with a Wertmessziffer rating of 6545/55 would be a powerfully built dog with ideal constitution, good angulation. It would be be relaxed and friendly yet very hard when provoked. It's courage and sharpness would be very good.
This is a chart of the system itself and an example rating.
