The standard error of measurement (SEM) is a measure of the expected variation in scores due to measurement error, and it provides a range of scores in which an individual's true score is likely to fall. When using a test score for selection or classification decisions, it is important to know the amount of measurement error associated with the particular score used to make the decision. Therefore, the SEM should be calculated at the score used to make the classification decision to ensure that the decision is based on accurate and reliable information.
