Psychological testing refers to a process in which individuals are assessed through standardized procedures and instruments that measure psychological characteristics, behaviors or abilities. These tests can be used for various purposes such as diagnosing mental disorders, identifying cognitive strengths and weaknesses, evaluating intellectual functioning, predicting job performance, and determining eligibility for special education services. The results of these tests provide valuable information to psychologists, educators or employers that can be used to make informed decisions about an individual's needs, abilities, or potential.
