What is reliability and validity in human resources?

What are the types of validity in education?
Validity can be demonstrated by showing a clear relationship between the test and what it is meant to measure. This can be done by showing that a study has one (or more) of the four types of validity: content validity, criterion-related validity, construct validity, and/or face validity.
What is content validity and examples?
the extent to which a test measures a representative sample of the subject matter or behavior under investigation.
