The cumulative value of ‘Minor discordance’, ‘Differential Diagnosis’, ‘Discordant’, ‘Unable to be assessed’ and ‘No submission received’ assessments for all cases in each survey are calculated.
The Non‐concordant Sum is an indication of the number of results in a survey that are assessed as not obtaining the target diagnosis. This type of assessment is also used in the RCPA Fellowship Part 2 exams where 4 out of 15 incorrect answers are allowed.
