Arce, Alvaro J.; Wang, Ze – International Journal of Testing, 2012
The traditional approach to scale modified-Angoff cut scores transfers the raw cuts to an existing raw-to-scale score conversion table. Under the traditional approach, cut scores and conversion table raw scores are not only seen as interchangeable but also as originating from a common scaling process. In this article, we propose an alternative…

Lamprianou, Iasonas – International Journal of Testing, 2008
This study investigates the effect of reporting the unadjusted raw scores in a high-stakes language exam when raters differ significantly in severity and self-selected questions differ significantly in difficulty. More sophisticated models, introducing meaningful facets and parameters, are successively used to investigate the characteristics of…

Pommerich, Mary; And Others – 1995
The Mantel-Haenszel (MH) statistic for identifying differential item functioning (DIF) commonly conditions on the observed test score as a surrogate for conditioning on latent ability. When the comparison group distributions are not completely overlapping (i.e., are incongruent), the observed score represents different levels of latent ability…

Liu, Xiufeng; Lesniak, Kathleen M. – Science Education, 2005
Using the US national sample from the Third International Mathematics and Science Study (TIMSS) and the Rasch modeling method, this study identified the conceptual progression sequence of various matter concept aspects, and compared students' latent abilities against the sequence. We found that the four matter aspects, i.e. conservation, physical…

Smith, Robert L.; Carlson, Alfred B. – 1995
The feasibility of constructing test forms with practically equivalent cut scores using judges' estimates of item difficulty as target "statistical" specifications was investigated. Test forms with equivalent judgmental cut scores (based on judgments of item difficulty) were assembled using items from six operational forms of the…
