Examining Rater Errors in the Assessment of Written Composition with a Many-Faceted Rasch Model.

Engelhard, George, Jr.

Journal of Educational Measurement, v31 n2 p93-112 Sum 1994

Rater errors (rater severity, halo effect, central tendency, and restriction of range) are described, and criteria are presented for evaluating rating quality based on a many-faceted Rasch (FACETS) model. Ratings of 264 compositions from the Eighth Grade Writing Test in Georgia by 15 raters illustrate the discussion. (SLD)
