Test-Retest Reliability: This term describes the consistency of scores when individuals take the same test at two different points in time. If a standardized test has high test-retest reliability, it means that individuals will likely score similarly when taking the test again after some time.

Interrater Reliability: Interrater reliability focuses on how consistent scores are when different raters or observers assess performance or behavior using a standardized test. High interrater reliability indicates that different raters would come up with similar scores for individuals' cognitive competence based on their observations.
