A method for detecting and interpreting disturbances of the local-independence assumption among items that share common stimulus material or other features is presented. Dichotomous and polytomous Rasch models are used to analyze structure of the learning outcome superitems. (SLD)

Two indices for measuring the degree of conformity or consistency of an individual examinee's response pattern on a set of items are developed. The use of the indices for spotting aberrant response patterns of examinees is detailed. (Author/JKS)

The effects of repeaters (testees included in both administrations of two forms of a test) on the test equating process are examined. It is shown that repeaters do effect test equating and tend to lower the cutoff point for passing the test. (JKS)

A debate concerning specific issues and the general usefulness of the Rasch latent trait test model is continued. Methods of estimation, necessary sample size, and the applicability of the model are discussed. (JKS)

TAILOR, a computer program which implements an approach to tailored testing, was examined by Monte Carlo methods. The evaluation showed the procedure to be highly reliable and capable of reducing the required number of tests items by about one half. (Author/JKS)

Statements made in a previous article of this journal concerning the Rasch latent trait test model are questioned. Methods of estimation, necessary sample sizes, several formuli, and the general usefulness of the Rasch model are discussed. (JKS)

Describes measurement problems associated with computer based testing (CBT) programs when they are part of a computer assisted instruction curriculum. Topics discussed include CBT standards; selection of item types; the contamination of items that arise from test design strategies; and the non-equivalence of comparison groups in item analyses. (8…

This experiment was designed to assess the ability of item writers to construct truly parallel tests based on a "duplicate-construction experiment" in which Cronbach argues that if the universe description and sampling are ideally refined, the two independently constructed tests will be entirely equivalent, and that within the limits of item…

As a preliminary step in customizing the Stanford Achievement Test, a study was made to compare the test items at each level with the curriculum objectives of a Florida school district, classifying them as either matching, above or below grade level, or unmatching. Results are shown in table form. (TE)

This article presents a model that can be used by local school districts for reanalyzing standardized test results to obtain a more valid assessment of local learning objectives can be used to identify strengths/weaknesses of existing programs as well as individual students. (EGS)

Instructional programs organized according to modern educational technology are discussed within the purposes of criterion-referenced measurements used. The problems of criterion-referenced measurements include scoring and score interpretation, item and test analysis, and mastery testing. An overview of solutions and approaches to the problems and…

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…

A model is presented using examinee judgements in detecting ambiguous/misinterpreted items on teacher-made criterion-referenced tests. A computational example and guidelines for constructing domain categories and interpreting the indices are presented. (Author/PN)

The effects of test-item selection on total test reliability and validity were investigated. It was posited that in a reading comprehension test, the knowledge displayed by the examinees is of interest only as it is a valid measure of how much a student learned from reading or comprehending a stimulus paragraph. Selection of items solely on the…
