Huitzing, Hiddo A.; Veldkamp, Bernard P.; Verschoor, Angela J. – Journal of Educational Measurement, 2005
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…

Using Set Covering with Item Sampling to Analyze the Infeasibility of Linear Programming Test Assembly Models
Peer reviewed Peer reviewed
Direct linkDirect link
Huitzing, Hiddo A. – Applied Psychological Measurement, 2004
This article shows how set covering with item sampling (SCIS) methods can be used in the analysis and preanalysis of linear programming models for test assembly (LPTA). LPTA models can construct tests, fulfilling a set of constraints set by the test assembler. Sometimes, no solution to the LPTA model exists. The model is then said to be…
