Psychometrics is a broad term used to define the theory behind the use and practice of psychological assessments.

Psychological assessments comprise the measurement of psychological constructs and how that information is used in a clinical setting to help formulate the clinical case and make treatment decisions. Psychometrics is also used in a forensic setting to answer questions about a person involved in the legal system, such as criminal prosecution or for a civil matter (e.g., custody dispute). Data from psychological assessments is also used to improve efficiency and overall functioning in an organizational setting.
