Abstract: A computer program (10) and a method for creating non-verbal test items (20) to target a level and a cognitive source of item difficulty for psychological tests comprising a test configuration module (30) for choosing an ability to be tested, an item type, and a general appearance of the items (20), an item specification module (40) for choosing one of a plurality of blueprints, and an item creation module (50) for creating each item (20). Each item (20) comprises a stem (90) and a list of response alternatives (100). Both the stem (90) and the list of response alternatives (100) each comprise a plurality of objects (110). The blueprints allow a user to create and immediately use the items (20) without having to conduct empirical tryouts. Tests can be administered either as fixed-content paper tests, fixed-content computer tests, or adaptive-content computer tests.
