It would be expected, merely because of restriction of the ability range (and ignoring any changes in skills or abilities being assessed), that the reliability will be less in the Part Consequently, smaller standard errors translate to more sensitive measurements of student progress. Of necessity SCEs are taken by small numbers of candidates, being the final knowledge-based assessment for specialty trainees.MethodsThree separate studies were carried out.a) A Monte Carlo analysis of the effects upon Please join the conversation on the NWEA Twitter and Facebook channels! navigate here
In the diagram at the right the test would have a reliability of .88. Holsgrove, however, points out that the reliability of an assessment can be improved not only by reducing the error variance, but that one "can also take steps to increase subject variance" Increasing Reliability It is important to make measures as reliable as is practically possible. So, to this point we’ve learned that smaller SEMs are related to greater precision in the estimation of student achievement, and, conversely, that the larger the SEM, the less sensitive is http://web.cortland.edu/andersmd/STATS/sem.html

Reliability also shows problems when numbers of candidates in examinations are low and sampling error affects the range of candidate ability.

The SEM is an estimate of how much error there is in a test. This could happen if the other measure were a perfectly reliable test of the same construct as the test in question.
