This is the report of a project which explored psychometric properties of response-time data and developed a model in which response-time was incorporated in scoring achievement tests. Validation of the model with real data has not yet been done, though the foundation of the model is based on theoretical and empirical research conducted in the past few years. The intention of the model is to try to quantify individual differences in information-processing skills in terms of a latent response-time variable analogous to the ability variable in latent trait theory which affects the time taken by an examinee to answer each of a given set of test items. We did not attempt to give a precise psychological meaning for this construct beyond saying that it may be regarded as a pervasive trait of individuals to be slow or quick in solving items of a certain domain. The other object of the project was to apply adaptive testing techniques to the interactive mode of actual instructions and testing with computer-managed routing systems.
