There is nothing on a site you can see as of course each test is different depending on the location, assessor etc but the broad outline for what the assessors are measuring is here:
It is not something you can really train for specifically.
Temperament Assessment in Dogs
The position of the dog in society and the attitude of it towards dogs, regardless of breed, have undergone quite striking changes in the last few years. No longer is he regarded solely as “man’s best friend” and the growth of a powerful anti-dog lobby has meant that the overwhelming coverage given to dogs and dog incidents/events has been both negative and critical.
Therefore the importance of breeding for sound temperament and the building on that by socialising the puppy sufficiently is now more important than ever. Apart from having a pleasant companion around the house you will have an animal that is a pleasure to take out and about in public – one, moreover, which will do a good public relations job not only for the breed but for dogs in general!
Many owners will not have any experience of what is involved in temperament assessment and may feel some apprehensions on that score. It is purely what its name implies and is not an assessment of the owner’s ability as a trainer. It is concerned with how the dog behaves in every day settings which, after all, is where the majority of our dogs spend the bulk of their time.
What sort of impression does it give: Friendly, reserved, calm, confident etc?
How does it react to a friendly approach? A dog of sound temperament should not show fear of or aggression towards a person approaching its handler in a normal manner (unless it has been trained in an undesirable way).
What is the reaction to an unusual advance – perhaps someone with a limp or on crutches or carrying a large package of some sort over a shoulder, walks past the dog. The dog is never threatened.
Will noise prove upsetting – daily life in urban areas always embraces exposure to noise of some sort or another; cars backfiring, loud engines, and aircraft flying overhead and so on.
Reaction to traffic, moving and stationary.
Reaction to unusual obstacles that are encountered in normal surroundings eg road works, small ditches, low fences etc.
Reaction to other dogs (non aggressive) and to a crowd of friendly/neutral people.
How does the dog react being left alone without the owner? And how does the dog behave off lead?
The Rottweiler Club evolved the idea of character assessments in the 1960s with the aim of maintaining awareness of the importance of good temperament in the breed; however the assessment is not breed specific.
Dogs may be graded “excellent”; “good pass” or of course fail.
