Achievement Tests and Latent Structure Models. Studies in Measurement and Methodology, Work Unit 3: Psychometric Problems in Achievement Tests.
Wilcox, Rand R.
In the past, several latent structure models have been proposed for handling problems associated with measuring the achievement of examinees. Typically, however, these models describe a specific examinee in terms of an item domain or they describe a few items in terms of a population of examinees. In this paper, a model is proposed which allows a population of examinees to be described in terms of an item domain. As is illustrated, the model yields a new formula score which allows guessing to vary over the population of examinees. (Author)
