Calibrating Essay Markers With The Partial Credit Model, Geoff Masters, Siek Khoo
Dr Siek Toon Khoo
This paper shows how a range of differences in marker behaviour, including leniency/severity and central tendency, can be detected and investigated using the Rasch partial credit model. The method allows for variations in the use of rating categories by estimating a set of rating 'thresholds' for each assessor. By calibrating each assessor's rating behaviour in this way, the method automatically takes account of detected differences among assessors in the measurement process.
