2.2.8.c. Test-taking procedure: testing space
The space is appropriate for the psychodiagnostic assessment in question. This means, among other things, that there is an adequately lit, quiet area free of dust and smoke, and that the chair and table provided are suitable for the client to work on and at without a problem for some time. Workplace health-and-safety standards (from the Dutch Ministry of Social Affairs and Employment, n.d.), for example, can be considered as a guide for the appropriate set-up of the testing space. The psychologist ensures that any disturbances that could distract from the test are kept to a minimum, so that there are as few deviations as possible from the standard situation in which the norms for the psychodiagnostic instrument were collected. Deviations within the testing space, such as a tight or cramped room or a room full of people who are causing distractions, can have a negative impact on test performance, so that the scores can no longer be interpreted in accordance with the norms for the psychodiagnostic instrument.
