I agree with all that has been said before.
When a 'checkee' is being checked by a checker, he/she will often take comfort from the fact that a more qualified/experienced pilot is also at the controls and therefore not display the degree of captaincy that he/she would were they on their own or with Granny, etc.
When solo or accompanied by non pilots in the other front seat, this often changes in my experience (as Instructor, Examiner on SEP/MEP and Jet) and the checkee becomes necessarily a much more self-reliant individual.
So to set the ground rules to start with is good. The checkee needs to be told to display captaincy skills to the checker, as well as basic flying ability, as an integral part of the check. As long as the decisions made are safe, even if not always what the checker would do in the same situation, then they can be discussed on the ground afterwards.
