The use of aptitude tests for selections is a rather spread practice, even if the social representation about this type of tools does not seem to give sci-entific sense. Although Verona prefers the use of aptitude tools, the trend was to construct tests directed to abilities (skills), cultural competencies and knowledge. This has been done respecting the needs of the study plan-ning of each faculty. The present report explains the procedures used to adjust tests, and it examines areas of items, subdivided according to vari-ous stimulus-situations. Finally it briefly refers to a special handbook made by the Centro Docimologico and directed to specialized personnel (staff) for test administration.
