This study was patterned after a previous study by Skaggs and Lissitz (1992) in which inconsistency of differential item functioning (DIF) was reported across test administrations. They suggested multidimensionality of test data as one possible reason for inconsistency. Therefore, in this study, DIF indices which were developed recently with a…

The purpose of this study was to examine rater, domain, and gender influences on the assessed quality of student writing using weighted and unweighted scores. Twenty rates were randomly selected from a group of 87 operational raters contracted to rate essays as part of the 1993 field test of the Georgia High School Writing Test. All of the raters…

Gender differences in answers to constructed-response reading items from a state assessment program were studied with four raters rating approximately 500 papers at two grade levels. Results indicate that number of words written and number of unrelated responses show significant gender differences and are related to holistic scores. (SLD)

To understand the achievement gap between Black and White students, test performance on Delaware statewide assessments was studied. The study focused on Black-White test score gaps in reading, mathematics, and writing across grades 3, 5, 8, and 10 by achievement level, item format, and gender within each racial/ethnic group over time.
