The importance of item difficulty (equated delta) was explored as a predictor of differential item functioning of Black versus White examinees for 4 verbal item types using 13 Graduate Record Examination forms and 11 Scholastic Aptitude Test forms. Several significant racial differences were found. (TJH)

Differential item functioning (DIF) methodology for revealing sources of item difficulty and performance characteristics of different groups was explored. A total of 150 Scholastic Aptitude Test items and 132 Graduate Record Examination general test items were analyzed. DIF was evaluated for males and females and Blacks and Whites. (SLD)
