A method for determining at least one competency relationship to be used as a basis for selection of a dose-related recording parameter for an examination process, in particular the recording of a timed series of x-ray images as an x-ray image dataset, of a patient at an x-ray device, between at least one competency value describing a user-specific or user-group specific user competency in respect of the evaluation of recorded x-ray images and at least the at least one recording parameter. The method includes displaying a plurality of x-ray image datasets corresponding to different recording parameters and/or having different image contents described by image content parameters； recording, for each x-ray image dataset, at least one measured value describing the competency value based on an interaction of a user with an operating device assigned to a display device； and determining, based on the measured values, the competency relationship describing the recording parameter-dependent competency value.
