Evaluators use a variety of different tests depending on the nature of the evaluation and any allegations that may have been made by either party. Most evaluations will include some sort of psychological or 'personality' test
, such as the Minnestoa Multiphasic Personality Index (MMPI or MMPI II), the Millon Clinical Multiaxial Inventory-III (MCMI-III), or the Bricklin Perceptual Scales (BPS).
Some evaluators still use the Rorschach test, also commonly called the "Ink Blot" test. We don't feel that the Rorschach is an appropriate test when used in the context of a custody evaluation, and it's our position that people should not take the Rorschach during or as part of a custody evaluation.
