Psychologists and Therapists administer tests and assessments for a wide variety of reasons. Children who are experiencing difficulty in school, for example, may undergo aptitude testing or tests for learning disabilities. Tests for skills such as dexterity, reaction time and memory can help a neuropsychologist diagnose conditions such as brain injuries or dementia.
If a person is having problems at work or school, or in personal relationships, tests can help a psychologist understand whether he or she might have issues with anger management or interpersonal skills, or certain personality traits that contribute to the problem. Other tests evaluate whether clients are experiencing emotional disorders such as anxiety or depression.
