The 2011 NAEP-TIMSS linking study conducted by the National Center for Education Statistics (NCES) was designed to predict Trends in International Mathematics and Science Study (TIMSS) scores for the U.S. states that participated in 2011 National Assessment of Educational Progress (NAEP) mathematics and science assessment of eighth-grade students.…

Direct linkLissitz, Robert W.; Hou, Xiaodong; Slater, Sharon Cadman – Journal of Applied Testing Technology, 2012
This article investigates several questions regarding the impact of different item formats on measurement characteristics. Constructed response (CR) items and multiple choice (MC) items obviously differ in their formats and in the resources needed to score them. As such, they have been the subject of considerable discussion regarding the impact of…

Peer reviewedFreedle, Roy; Kostin, Irene – Journal of Educational Measurement, 1990
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)

Peer reviewedDorans, Neil J.; And Others – Journal of Educational Measurement, 1992
The standardization approach to comprehensive differential item functioning is described and contrasted with the log-linear approach to differential distractor functioning and the item-response-theory-based approach to differential alternative functioning. Data from an edition of the Scholastic Aptitude Test illustrate application of the approach…

Spray, Judith A.; Miller, Timothy R. – 1992
A popular method of analyzing test items for differential item functioning (DIF) is to compute a statistic that conditions samples of examinees from different populations on an estimate of ability. This conditioning or matching by ability is intended to produce an appropriate statistic that is sensitive to true differences in item functioning,…

Nandakumar, Ratna – 1992
The phenomenon of simultaneous differential item functioning (DIF) amplification and cancellation and the role of the SIBTEST computer program in detecting it were studied. A variety of simulated test data was generated for this purpose. In addition, the following real test data were used: (1) American College Testing program data for 2,115 males…

Ryan, Katherine E. – 1992
Whether specification of focal group membership based on ethnicity as well as educational opportunity affects differential item functioning (DIF) of test items was studied. Subjects were 4,342 freshmen admitted to a large midwestern university who completed the 40-item Advanced Mathematics Placement Examination in the spring of 1991. There were…

Peer reviewedScheuneman, Janice Dowd; Gerritz, Kalle – Journal of Educational Measurement, 1990
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)

Kulick, Edward; Hu, P. Gillian – 1989
The relationship of differential item functioning (DIF) to item difficulty on the Scholastic Aptitude Test (SAT) was examined, based on data from nine recent administrations of the test from June 1986 through December 1987. This pool of information includes item statistics on 765 verbal and 540 mathematical items computed for subgroups of White,…

Coffman, William E. – 1978
The Iowa Tests of Basic Skills were administered to over 600 black and white students in grades six through nine, to determine if the test showed bias against minorities. Outliers were identified from test results. Outliers are items which differ from the central core of test items because they fall outside the range expected from a random…
