The symposium, "Taming the Rasch Tiger: Using Item Response Theory in Practical Educational Measurement," was organized to deemphasize the technical complexities of item response theory (IRT) and to show the audience how IRT can be used in practical educational measurement. Four papers from the symposium are summarized and comments are…

Using the analogy of temperature measurement, the Rasch model is presented with arguments for its adoption as the basic scaling technique for achievement measures. Three extensions of the Rasch model for more complex testing are developed. Test development for the British national assessment program and the promise of item banking are also…

For many years personalization of achievement testing has been impossible in all but the simplest forms. Recently, item response theory (IRT), or latent trait theory, has emerged as a valuable tool which brings far greater flexibility to the process than had previously been possible. The single parameter Rasch Model, a mathematical model developed…

This paper argues that no single measurement strategy serves all purposes and that applying methods and techniques which allow a variety of data elements to be retrieved and juxtaposed may be an investment in the future. Item response theory, Rasch model, and latent trait theory are all approaches to a single conceptual topic. An abbreviated look…

Item banking offers psychometric efficiency and user flexibility when compared with standardized testing. This article discusses the theories, procedures, and potential of item banks for improving educational measurement. (BS)

This paper has shown the advantages of tailored testing over traditional methods, the need for latent trait theory in the application of tailored testing, and some of the results available to show the quality of estimates obtained by tailored testing procedures. Since the tailored testing procedures overcome many of the problems with traditional…

The process of writing test items is analyzed, and a blueprint is presented for an authoring system for test item writing to reduce invalidity and to structure the process of item writing. The developmental methodology is introduced, and the first steps in the process are reported. A historical review traces the advances made in the field and the…

The use of item banks and item response theory has resulted in new ways to misinterpret and misuse tests through customized, yet standardized, achievement test batteries. The new test batteries create the possibility of serious misunderstandings based on the idea that any subset of items from the pool with a proper range of difficulties will…

Criticisms of norm referenced standardized tests are contrasted with the assumption and claims of proponents of Rasch model testing and item banking. The Rasch test theory model is based on the assumption of equal interval curriculum referenced scales for both students' abilities and test item difficulties. The Portland school district has…

The potential value of developing item banks that would both guarantee the quality of teacher-made examinations and allow for national comparison of student achievement is described. Use of Rasch model methods, rather than classical item analysis techniques, to calibrate the items for these banks is illustrated. (BS)

Computerized adaptive testing for language teaching and learning takes advantage of two properties of the computer: its number-crunching and multiple-branching capabilities. Adaptive testing has also been called tailored testing because it aims at presenting items that suit the student's competence and that are informative, using an item bank and…

Possible future practices in testing are discussed, with a critique of current educational measurement. As standardized achievement tests are used for wide-ranging purposes, there will be increasing reliance on item response theory and national item banks. A national system of monitoring development and use of tests will probably emerge. (SLD)

Many problems are encountered by school districts regardless of size. State and federal involvement in education provides certain financial resources, but also makes demands for accountability. This creates conflicts between local program development and the requirements of state and federal regulations, and particularly complicates the…

Increasing numbers of state-mandated testing programs have resulted in the selection of norm-referenced tests (NRTs) for statewide assessment. Adaptation or customization of existing tests has become a viable solution for individual programs. Changes in test instruments have arisen from the behaviorist approach and mastery learning, minimum…

It has been recommended that the National Assessment of Educational Progress (NAEP) specify comprehensive exercise domains to measure academic achievement, and provide a national item pool to measure the objectives in these domains. These domain specifications and item pools would serve to satisfy the increasing demand for valid, accurate, and…
