The standard error of measurement (SEM) is the most appropriate index to determine the level of confidence in a test-taker's score. It estimates the amount of error that occurs when a person takes the same test multiple times. A high SEM indicates lower reliability of the test and lower confidence in the scores, while a low SEM indicates higher reliability and higher confidence in the scores. In this case, the test-taker scored above the cut-off score, but the psychologist needs to know how much confidence to place in this score. Therefore, the SEM will provide an estimate of the error associated with the score and help the psychologist determine the level of confidence in the score.
