Using Set Covering with Item Sampling to Analyze the Infeasibility of Linear Programming Test Assembly Models

Peer reviewed

Direct 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…

Evaluation of Implied Orders as a Basis for Tailored Testing with Simulation Data.

Peer reviewed

Cliff, Norman; And Others – Applied Psychological Measurement, 1979

Monte Carlo research with TAILOR, a program using implied orders as a basis for tailored testing, is reported. TAILOR typically required about half the available items to estimate, for each simulated examinee, the responses on the remainder. (Author/CTM)
