Validity and reliability are two important characteristics of behavioral measure and are referred to as psychometric properties. It is important to bear in mind that validity and reliability are not an all or none issue but a matter of degree. Validity: Very simply, validity is the extent to which a test measures what it is supposed to measure.

Reliability refers to the extent to which the same answers can be obtained using the same instruments more than one time. Reliability is a necessary ingredient for determining the overall validity of a scientific experiment and enhancing the strength of the results. Debate between social and pure scientists, concerning reliability, is robust and ongoing. Assessment validity is a bit more complex because it is more difficult to assess than reliability. There are various ways to assess and demonstrate that an assessment is valid, but in simple terms, assessment validity refers to how well a test measures what it is supposed to measure.
