Difference between psychometrics and psychological tests:

Psychometrics is a tool for understanding the human mind, and is mainly used in a "nominal" sense. On the other hand, psychometrics is a practical activity that uses tests as a tool to understand the human psyche, and it is mainly used in the sense of "verb".

Psychometrics focuses on quantification, which is usually the process of quantitatively describing and determining the characteristics of something using numbers. In practice, psychometrics is a branch of psychology.

Overall, testing is a tool, while measurement is the process of making and using such a tool. Thus, the meaning of psychometrics is a little wider in scope. There are many other methods of psychometric measurement besides psychometric testing, such as observation, interviewing, work analysis, and case studies.
