Abstract
A method for use of pretest items in a test to calculate interim scores is provided. The method includes, for example, a computer implemented test having a plurality of test items that include, for example, a plurality of operational items and one or more pretest items having one or more pretest item parameters. An interim latent construct estimate is calculated using both operational and pretest items. The error for the latent construct estimation is controlled by weighting the contribution of the one or more pretest items.
