Which of the following statements is true in the case of a test prepared by you as a teacher?

If a test is valid it must also be reliable, because valid measurement of the intended trait requires consistent results.

Validity means a test measures what it claims to measure, while reliability means it measures consistently.

A test cannot consistently hit the right target unless its scores are stable, so validity implies reliability.

The converse fails: a reliable test can be consistent yet measure the wrong thing, so reliability does not imply validity.

This rules out the claims that a reliable test is automatically objective or automatically valid.

Objectivity and usability are further test qualities, but they do not follow simply from reliability alone.
