Decoding variance and predictive ability in selection systems: An application of Gauthier’s framework of rater cognitions

(2016) framework (Lewis, 2021). [...]not only should rater training involve maintaining consistent perceptions of good and poor performance among the raters, but an additional focus on maintaining consistent perceptions of the assessed competencies should be considered. (2018), the shift could result from the range-frequency of raters’ internal scales or the emphasized performance aspects within assessment judgments. [...]understanding raters’ internal scales of performance aspects may indicate if biased or inaccurate ratings are likely to be present and to establish the optimal rater training procedures for reducing the variance. According to Mishra and Roch (2013), measuring the effects of cultural values on performance ratings can be useful for understanding the schemas or preferences that raters form surrounding the competencies of interest in the performance evaluation. [...]Sebok and Syer (2015) concluded that the substantial variance in ratings may result from raters’ possession of different interpretations of performance.
