Double Marking Investigation

An investigation of targeted double marking for GCSE and GCE

Double marking is the marking of a script by two assistant examiners or markers; the final mark is an average of the two separate marks.  The purpose of this project was to investigate whether the final mark is affected either by the way in which markers were paired with each other - either randomly, or lenient and severe markers together - or by whether markers are able to see the marks given by each other.  In examining these issues, the researchers were also able to judge whether double marking improved the reliability of the marks given.
