As the reliability increases, the SEMdecreases. It should however be emphasised that there is a standard correction for restriction of range which cannot also be applied.

ConclusionsStandard error of measurement is a better measure of the quality of an assessment than is reliability, particularly when the ability range of the candidates must necessarily be restricted, as is Student B has an observed score of 109.

The MRCP(UK) Part 1 and Part 2 Written Examinations are criterion-referenced, single-version, machine-marked papers. It also tells us that the SEM associated with this student’s score is approximately 3 RIT—this is why the range around the student’s RIT score extends from 185 (188 - 3)

A review of the reliability of the MRCP(UK) Part 1 Examination between 1984 and 2001, during which period the examination consisted of 300 true-false items with negative marking, showed that the
