Judd, Wallace – Practical Assessment, Research & Evaluation, 2009
Over the past twenty years in performance testing a specific item type with distinguishing characteristics has arisen time and time again. It's been invented independently by dozens of test development teams. And yet this item type is not recognized in the research literature. This article is an invitation to investigate the item type, evaluate…

Lord, Frederic M. – 1980
The purpose of this book is to make it possible for measurement specialists to solve practical testing problems through the use of item response theory (IRT). The topics, organization, and presentation are those used in a 4-week seminar held each summer for the past several years. The material is organized to facilitate understanding; all related…

DeAyala, R. J.; Koch, William R. – 1986
A computerized flexilevel test was implemented and its ability estimates were compared with those of a Bayesian estimation based computerized adaptive test (CAT) as well as with known true ability estimates. Results showed that when the flexilevel test was terminated according to Lord's criterion, its ability estimates were highly and…

Olsen, James B.; And Others – 1986
Student achievement test scores were compared and equated, using three different testing methods: paper-administered, computer-administered, and computerized adaptive testing. The tests were developed from third and sixth grade mathematics item banks of the California Assessment Program. The paper and the computer-administered tests were identical…

Lord, Frederic M. – 1971
Some stochastic approximation procedures are considered in relation to the problem of choosing a sequence of test questions to accurately estimate a given examinee's standing on a psychological dimension. Illustrations are given evaluating certain procedures in a specific context. (Author/CK)

Hambleton, Ronald K.; And Others – 1975
The success of objectives-based programs depends to a considerable extent on how effectively students and teachers assess mastery of objectives and make decisions for future instruction. While educators disagree on the usefulness of criterion-referenced tests the position taken in this monograph is that criterion-referenced tests are useful, and…

Gustafsson, Jan-Eric – 1977
The Rasch model for test analysis is described and compared with two-parameter and three-parameter latent-trait models. Conditional maximum likelihood equations for estimating item parameters are derived, and estimates of person parameters are described together with their confidence intervals. Goodness of fit tests are discussed, including a…
