The moderation of examination answer books is an area where quality assurance is essential, and should be employed to ensure that an examination paper’s standard, content and span, marking, etc. are fair and reasonable. A scientific procedure is given for finding the minimum number of answer books to moderate (sample size) so that the statement – that no answer book in a set will contain more than a prespecified proportion of errors – can be made with a pre-specified confidence. The procedure is an extension and enhancement of previous research , and guarantees a statistical statement in all cases.
