A test that is consistent in measuring what it is supposed to measure is considered to have

A) reliability.
B) generalizability.
C) validity.
D) constructability.

Reliability refers to the consistency of a measurement tool in yielding the same results when used repeatedly under similar conditions. It does not necessarily mean that the test is measuring what it is supposed to measure (validity) or that the results can be generalized to other populations or situations (generalizability) or that the test assesses a specific construct (constructability).
