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; 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…
