Approaches proposed for educational diagnostic assessment are reviewed and identified as deficit assessment and error analysis. The development of diagnostic instruments may require a reexamination of existing psychometric models and development of alternative ones. The psychometric and content demands of diagnostic assessment all but require test…

This articles discusses ways to respond to the need for criterion referenced information using Bayes' theorem, a method coupled with criterion referenced testing in the early 1970s. The theorem determines the most likely classification for an examinee from a dichotomous choice or through placement on a categorical or interval scale. A discussion…

Recent changes in the structure of curriculum and the instructional system in Texas have required a major reorganization of teaching, evaluating, budgeting, and planning activities in the local education agencies, which has created the need for a database. The history of Richardson Instructional Management System (RIMS), its data processing…

The potential use of criterion referenced tests (CRT) and norm referenced tests (NRT) in the same testing program is discussed. The advantages and disadvantages of each are listed, and the best solution, a merging, is proposed. To merge CRTs and NRTs into an overall testing program, meaningful and useful to all levels, consideration must be given…

The DX SYSTEM of Diagnostic Testing is an easy-to-use computerized system for developing and administering diagnostic tests. A diagnostic test measures a student's mastery of a specific domain (skill or content area). It examines the necessary subskills hierarchically from the most to the least complex. The DX SYSTEM features tailored testing with…

A contemporary mathematics curriculum emphasizes using a variety of evaluation techniques to determine student achievement. Too frequently in the past, standardized norm- referenced tests and their results provided the main information related to student achievement. These tests have not presented objectives for teachers to use in teaching…

The following steps have been taken to accomplish the goals of the Wisconsin Pupil Assessment Program: the development of objective-referenced tests; the administration of a standardized norm-referenced test; reporting of trends in performance on these tests; and the availability of two testing services and personnel for consultation purposes.…

Grade Level Evaluation (GLE) is a computerized criterion-based reference examination designed for elementary schools and secondary schools. The advanced software program is coupled with an in-depth curriculum covering basic computational and critical thinking skills for each grade. This packet introduces the software and its use. GLE is a…

This report describes the development, operation, maintenance, and future prospects of the item banks pioneered by the Portland (Oregon) School District. At the time of this report, there were 3,500 mathematics, 2,200 reading, and 2,300 language usage items calibrated under the fixed parameter model of item response theory (IRT) for Grades 3-8.…

This paper describes two case studies of testing programs at local levels. The work was conducted as part of the Assessment Development and Use component of the Northwest Regional Educational Laboratory's (NWREL) Assessment and Development project. Two school districts were recruited to participate in this effort--McMinnville, Oregon, and Kyrene,…
