Which Test Requires a Certified Psychologist for Administration?

The Minnesota Multiphasic Personality Inventory (MMPI)

The test that identifies mental functioning and must be administered by a certified psychologist or therapist is the Minnesota Multiphasic Personality Inventory (MMPI). The MMPI is a widely used self-report inventory composed of true/false questions aimed at establishing a clinical profile. This assessment tool was first published in 1943 and has since been revised, with the current version being the MMPI-2. It is designed to measure a range of psychological conditions and personality attributes. The MMPI is often used for various purposes, including clinical diagnosis, occupational screening, and in settings such as law enforcement and counseling.

Other personality assessments mentioned, such as the Big 5, 16 Personalities Test, and The Career Questionnaire, do not require administration by a certified psychologist or therapist and are not as clinically focused as the MMPI.
