Equating without an Anchor for Nonequivalent Groups of Examinees
Peer reviewed Peer reviewed
Direct linkDirect link
Longford, Nicholas T. – Journal of Educational and Behavioral Statistics, 2015
An equating procedure for a testing program with evolving distribution of examinee profiles is developed. No anchor is available because the original scoring scheme was based on expert judgment of the item difficulties. Pairs of examinees from two administrations are formed by matching on coarsened propensity scores derived from a set of…

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…

Albano, Anthony D. – Journal of Educational Measurement, 2013
In many testing programs it is assumed that the context or position in which an item is administered does not have a differential effect on examinee responses to the item. Violations of this assumption may bias item response theory estimates of item and person parameters. This study examines the potentially biasing effects of item position. A…

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…

Lawrence, Ida M.; Rigol, Gretchen W.; Van Essen, Thomas; Jackson, Carol A. – College Entrance Examination Board, 2003
This paper provides an historical perspective on the content of the SAT. The review begins at the beginning, when the first College Board SAT (the Scholastic Aptitude Test) was administered to 8,040 students on June 23, 1926. At that time, the SAT consisted of nine subtests: Definitions, Arithmetical Problems, Classification, Artificial Language,…
