The reliability coefficient (r) indicates the amount of consistency in the test. First, the middle number tells us that a RIT score of 188 is the best estimate of this student’s current achievement level. It's unfortunate that we also talk of Cronbach's alpha as a "lower bound for reliability" since this might have confused you. The most notable difference is in the size of the SEM and the larger range of the scores in the confidence interval.While a test will have a SEM, many tests will
