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…

Guo, Hongwen; Liu, Jinghua; Dorans, Neil; Feigenbaum, Miriam – ETS Research Report Series, 2011
Maintaining score stability is crucial for an ongoing testing program that administers several tests per year over many years. One way to stall the drift of the score scale is to use an equating design with multiple links. In this study, we use the operational and experimental SAT® data collected from 44 administrations to investigate the effect…

Liu, Jinghua; Sinharay, Sandip; Holland, Paul W.; Feigenbaum, Miriam; Curley, Edward – Educational Testing Service, 2009
This study explores the use of a different type of anchor, a "midi anchor", that has a smaller spread of item difficulties than the tests to be equated, and then contrasts its use with the use of a "mini anchor". The impact of different anchors on observed score equating were evaluated and compared with respect to systematic…

Liu, Jinghua; Zhu, Xiaowen – ETS Research Report Series, 2008
The purpose of this paper is to explore methods to approximate population invariance without conducting multiple linkings for subpopulations. Under the single group or equivalent groups design, no linking needs to be performed for the parallel-linear system linking functions. The unequated raw score information can be used as an approximation. For…

Haberman, Shelby J.; Guo, Hongwen; Liu, Jinghua; Dorans, Neil J. – ETS Research Report Series, 2008
This study uses historical data to explore the consistency of SAT® I: Reasoning Test score conversions and to examine trends in scaled score means. During the period from April 1995 to December 2003, both Verbal (V) and Math (M) means display substantial seasonality, and a slight increasing trend for both is observed. SAT Math means increase more…

Liu, Jinghua; Feigenbaum, Miriam; Dorans, Neil J. – College Board, 2005
Score equity assessment was used to evaluate linkings of new SAT® to the current SAT Reasoning Test™. Population invariance across gender groups was studied on the linkage of a new SAT critical reading prototype to a current SAT verbal section, and on the linkage of a new SAT math prototype to a current SAT math section. The results indicated that…

Liu, Jinghua; Allspach, Jill R.; Feigenbaum, Miriam; Oh, Hyeon-Joo; Burton, Nancy – College Entrance Examination Board, 2004
This study evaluated whether the addition of a writing section to the SAT Reasoning Test™ (referred to as the SAT® in this study) would impact test-taker performance because of fatigue caused by increased test length. The study also investigated test-takers' subjective feelings of fatigue. Ninety-seven test-takers were randomly assigned to three…

Liu, Jinghua; Feigenbaum, Miriam; Cook, Linda – College Entrance Examination Board, 2004
This study explored possible configurations of the new SAT® critical reading section without analogy items. The item pool contained items from SAT verbal (SAT-V) sections of 14 previously administered SAT tests, calibrated using the three-parameter logistic IRT model. Multiple versions of several prototypes that do not contain analogy items were…
