The article reviews error analysis procedures for two subtests of the Peabody Individual Achievement Test (reading recognition and reading comprehension). Suggestions are offered for composing and interpreting a pattern of errors on items from each subtest. (CL)

A latent class model for rating data is presented which provides an alternative to the latent trait approach of analyzing test data. It is the analog of Andrich's binomial Rasch model for Lazarsfeld's latent class analysis (LCA). Response probabilities for rating categories follow a binomial distribution and depend on class-specific item…

This article illustrates the use of generalizability theory in special education to estimate the reliability of a measure when there is more than one source of error in the universe of inference and how the effects from changing the number of items and/or raters can be evaluated. (Author)

Method, results, and conclusions are discussed of a study to compare responses to 3-choice test items with responses to 4-choice items when the question or statement being presented was held constant. (Author/AV)

The purpose of this study was to compare three technologies: the item forms technology (domain-referenced testing) of Hively et al. (1968), the hierarchical or stratified item forms technology of Ferguson (1969), and the algorithmic technology of Scandura (1971, 1973). (Author/RK)

The Strong Vocational Interest Blank responses of 93 students were used to construct six empirical scales similar to the scales of Holland's Vocational Preference Inventory. Correlation of scale scores with VPI scores suggested that meaningful estimates of VPI profiles are obtainable by scoring selected SVIB items. (Author)

In this paper consideration is given to the nature of the relationships among items within item forms and how these relationships compare with an ideal case for diagnostic tests in which if a person gets one item within an item form right then he would get all items within the item form correct. (Authors)

Results indicate that the troublesome scale/concept interaction which in past studies has lowered the internal validity of many investigations can be reduced by the simple expedient of controlling for homogeneity of domain of scales and concepts employed. (Authors)

Author presents a method for calculating item factor scores which are independent of item trait scores. (MB)

Paper reports on the use of a technique of item writing and item keying in personality scale construction which overcomes the drawbacks, while maximizing the advantages of unit response weighting. (Author)

The proportion of cross-validated and suggestively discriminating items in the area of preference or aversion for a large variety of activities, most of all of which imply excitement or potential excitement, suggests this as the most important finding from the item analysis done in this study. (Author)

Concern is raised about the wording of the Counselor Education Program Innovation Index items and about the response format. The influence of perceived item ambiguity andresponse format bias upon the results of the inventory are noted. A suggestion is made for ACES sponsorship of research descriptive of what counselor educators do and with what…
