THE 1965 CSE MONITORING EXPERIMENT: A COMMENT

Mr. Please criticizes a study reported by the NFER in 1966 which suggested that CSE grades were likely to be too lenient. He contests the relevance of the ‘regression line’ calculated by the experimenters which led to their conclusion that a number of examining boards were too lenient in their marking. It is claimed that the regression line is incompatible with the stated objective of the CSE examination which defines grade one as corresponding to a pass at O‐level in the same subject. A reply from G. F. Peaker finds the criticism justified, explains how it arose and how it could have been put right.
