The standard error of measurement (SEM) is the most useful indicator of reliability for the interpretation of individual scores because it provides an estimate of the amount of error that is inherent in a particular score. This allows us to interpret a score with more confidence knowing the range of scores that the true score is likely to fall within. Split-half variance and test-retest reliability are useful for assessing the consistency of a measure across multiple administrations, while item sampling is used to test the psychometric properties of individual test items.
