An Optimization Model for Test Assembly To Match Observed-Score Distributions. Research Report 94-7.
Download full textvan der Linden, Wim J.; Luecht, Richard M. – 1994
An optimization model is presented that allows test assemblers to control the shape of the observed-score distribution on a test for a population with a known ability distribution. An obvious application is for item response theory-based test assembly in programs where observed scores are reported and operational test forms are required to produce…

Optimal Assembly of Educational and Psychological Tests, with a Bibliography. Research Report 98-05.
van der Linden, Wim J. – 1998
The advent of computers in educational and psychological measurement has lead to the need for algorithms for optimal assembly of tests from item banks. This paper reviews the literature on optimal test assembly and introduces the contributions to this report on the topic. Four different approaches to computerized test assembly are discussed:…
