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…

The study compared two promising item response theory (IRT) item-selection methods, optimal and content-optimal, with two non-IRT item selection methods, random and classical, for use in fixed-length certification exams. The four methods were used to construct 20-item exams from a pool of approximately 250 items taken from a 1985 certification…

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…

Item response model applications to National Assessment of Educational Progress (NAEP) data specifically aimed at the uses of item response models in mathematics item banking are discussed. Approaches for addressing goodness of fit were organized into three categories: Checks on model assumptions, expected features, and additional model…

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…
