Final answer:
Test scores are assessed for their validity and reliability. Validity refers to the extent to which a test accurately measures what it is supposed to measure, while reliability refers to the consistency of test scores over time and across different test takers.
Step-by-step explanation:
Test scores are assessed for their validity and reliability. Validity refers to the extent to which a test accurately measures what it is supposed to measure. Reliability, on the other hand, refers to the consistency of test scores over time and across different test takers.
For example, if a test is considered reliable, it would produce similar scores for the same individual taking the test multiple times. However, a reliable test may not necessarily be valid if it does not measure the concept it intends to measure accurately.
In summary, while test scores may be stable and consistent (reliable), they may not always accurately measure the intended concept (valid). This is why both validity and reliability are important considerations in the assessment of test scores.
