This paper presents an algorithm for determining the number of items to measure each objective in a criterion-referenced test when testing time is fixed and when the objectives vary in their levels of importance, reliability, and validity. Results of four special applications of the algorithm are presented. (BS)

Essential for an effective criterion-referenced testing program is a set of test items that are "valid" indicators of the objectives they have been designed to measure. Unfortunately, the complex matter of assessing item validity has received only limited attention from educational measurement specialists. One promising approach to the item…

A new method was developed to assist in the selection of a test length by utilizing computer simulation procedures and item response theory. A demonstration of the method presents results which address the influences of item pool heterogeneity matched to the objectives of interest and the method of item selection. (Author/PN)

In this paper, an attempt has been made to synthesize some of the current thinking in the area of criterion-referenced testing as well as to provide the beginning of an integration of theory and method for such testing. (Editor)

In this paper, an attempt has been made to synthesize some of the current thinking in the area of criterion-referenced testing as well as to provide the beginning of an integration of theory and method for such testing. Since criterion-referenced testing is viewed from a decision-theoretic point of view, approaches to reliability and validity…

In light of the widespread use of competency testing, the authors consider that it is important to determine ways of developing and using competency testing to insure that it achieves its full potential. The paper, in three parts, introduces a model for the development and validation of competency tests, reviews several methods for setting…

Technical considerations associated with item selection and reliability assessment are considered in relation to criterion-referenced tests constructed to provide group information. The purpose is to emphasize test building and the evaluation of test scores in program evaluation studies. It is stressed that an evaluator employ a performance or…

The purpose of the investigation was to obtain some relationships among (1) test lengths, (2) shape of domain-score distributions, (3) advancement scores, and (4) several criterion-referenced test score reliability and validity indices. The study was conducted using computer simulation methods. The values of variables under study were set to be…

Reviewing psychometric and statistical developments in criterion- referenced testing, this paper presents six sections: uses of criterion- referenced test scores, reliability of criterion-referenced test scores, determination of test length, determination of cut-off scores, test development and validation, and summary and suggestions for further…

The problem of determining optimal test lengths with fixed total testing time has proved to be a difficult one for criterion-referenced test developers. An algorithm is needed which can be used by test developers to allocate available testing time to maximize the validity of their total criterion-referenced tests or testing programs. To be…

Four main approaches to customized testing are described, and their resulting scores' valid uses and interpretations are discussed. Customized testing can yield valid normative and curriculum-specific information, although cautious application is needed to avoid misleading inferences about student achievement. (SLD)

The success of objectives-based programs depends to a considerable extent on how effectively students and teachers assess mastery of objectives and make decisions for future instruction. While educators disagree on the usefulness of criterion-referenced tests the position taken in this monograph is that criterion-referenced tests are useful, and…

This instructional training package introduces practitioners to methods for developing, validating, using, and reporting criterion-referenced tests. It provides a comprehensive presentation of criterion-referenced testing technology. The package emphasizes the most recent substantive and technological advances in the field that are both important…

This paper highlights some special characteristics of criterion-referenced tests while comparing them with norm-referenced tests. Psychometric considerations involved in constructing a criterion-referenced test, including item analysis, reliability, and validity, are discussed, along with application of criterion-referenced testing to individual…

A review of educational measurement journals indicates that the decade of the 1970s and up until about 1984 was the time when substantial numbers of studies dealt with criterion-referenced measurement, and the era in which criterion-referenced measurement advances were made. Although there appears to be less interest in publications today, a…
