Walsh, Patrick – Education Finance and Policy, 2014
This paper quantifies the extent to which unified teacher pay scales and differential alternatives produce opportunity costs that are asymmetric in math and verbal skills. Data from the Baccalaureate and Beyond 1997 and 2003 follow-ups are used to estimate a fully parametric, selection-corrected wage equation for nonteachers, which is then used to…

Ruban, Lilia M.; McCoach, D. Betsy – Review of Higher Education, 2005
This study examined the differential impacts of SAT scores and high school rank, college academic level, motivational variables, and self-regulatory variables in explaining variance in the academic achievement of male and female collegians using structural equation modeling and multiple groups analyses. Significantly, in light of earlier research,…

Moses, Tim; Liu, Jinghua; Tan, Adele; Deng, Weiling; Dorans, Neil J. – ETS Research Report Series, 2013
In this study, differential item functioning (DIF) methods utilizing 14 different matching variables were applied to assess DIF in the constructed-response (CR) items from 6 forms of 3 mixed-format tests. Results suggested that the methods might produce distinct patterns of DIF results for different tests and testing programs, in that the DIF…

Temp, George – 1971
Differential prediction of grade point average for black and white freshman students was empirically investigated at 13 integrated institutions by comparison of regression planes. Particular attention was given to the possibility that prediction procedures that are appropriate for white (majority) students would under-predict the performance of…

Boldt, Robert F. – 1972
This paper describes several situations in which generalization of statistical results is not possible by representative sampling but which is attempted using corrections for selection of groups. The situations include hiring, admissions, differential classification, guidance, test score equating, and test score scaling. Evidence of inaccuracies…

Schultz, Matthew T.; Geisinger, Kurt F. – 1992
Research efforts have established that the Mantel-Haenszel procedure (MHP) is an effective method for detecting the presence of test items exhibiting differential item functioning (DIF). While the MHP has been advocated for situations where item response theory based methods may not be usable, recent findings have suggested that the performance of…
