What three criteria must a psychological test meet before it can be widely used?

The three criteria that a psychological test meets before it can be widely used would be:

· Standardization - To standardize a test, it must first be given to a large representative sample of people in which their scores will be set as the standard for comparison.

· Reliability - To be reliable, a test must yield consistent results. This is done by comparing scores on two halves of a test or by retesting.

and finally,

· Validity - The degree to which a test measures what it is supposed to measure.

I hope this was able to help you, have a nice day! :)
