Abstract
Cognitive psychology has an important impact on ability and achievement testing because many of the item types on educational tests have been studied as cognitive tasks. In this article, a system of designing tests from the cognitive perspective is described. Further, appropriate statistical models for estimating the effects of specific variables on psychometric properties are also described. Examples are presented from two different tests to show how the properties of items are predicted from the cognitive variables. The estimated effect parameters for the cognitive variables may be useful for item banking and test equating if the model has sufficient predictive power.
