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…

Several techniques exist to automatically put together a test meeting a number of specifications. In an item bank, the items are stored with their characteristics. A test is constructed by selecting a set of items that fulfills the specifications set by the test assembler. Test assembly problems are often formulated in terms of a model consisting…

Use of the Rasch model for vertical equating of tests is discussed. Although use of the model is promising, empirical results raise questions about the adequacy of the Rasch model. Latent trait models with more parameters may be necessary. (JKS)

"Assessing Student Performance" sets forth arguments for looking at testing and assessment. The exploration is more about morality and epistemology than about technology and politics. A principal assumption is that mainstream assessment and testing philosophy is flawed. (SLD)

The assessment framework underlying a science performance monitoring program is process-oriented and intended to appeal to generalizability theory for a suitable estimation paradigm. Preliminary applications are described. Results suggest that computerized question-banking, domain-sampling of questions, and generalizablity theory together provide…

The 63 items on skills in acquiring and using information from written documents contained in the Survey of Young Adult Literacy in the 1985 National Assessment of Educational Progress are analyzed. The analyses are based on a qualitative cognitive model and an item-response theory model. (TJH)
