Validity and Reliability

In medical education concerns of validity and reliability of the assessment method are always important. A valid assessment should measure what it intend to measure or was designed to measure. Validity refers to the degree that the evidence supports that the test interpretations are correct.

Reliability refers to the consistency of assessment and the ability of results to be generalized to other performances. Reliability implies that the same results will be obtained when the assessment is administered to a student under the same or similar conditions.
