The Stability of Rater Severity in Large-Scale Assessment Programs.

Congdon, Peter J.; McQueen, Joy

Journal of Educational Measurement, v37 n2 p163-78 Sum 2000

Studied the stability of rater severity over an extended rating period by applying multifaceted Rasch analysis to ratings of 16 raters of writing performances of 8,285 elementary school students. Findings cast doubt on the practice of using a single calibration of rate severity as the basis for adjustment of person measures. (SLD)
