This article considers psychometric properties of composite raw scores and transformed scale scores on mixed-format tests that consist of a mixture of multiple-choice and free-response items. Test scores on several mixed-format tests are evaluated with respect to conditional and overall standard errors of measurement, score reliability, and…

The major purpose of this study is to assess the conditions under which single scoring for constructed-response (CR) items is as effective as double scoring in the licensure testing context. We used both empirical datasets of five mixed-format licensure tests collected in actual operational settings and simulated datasets that allowed for the…

The present study examined the psychometric equivalence of administering a computer-based version of the Gifted Rating Scale (GRS) compared with the traditional paper-and-pencil GRS-School Form (GRS-S). The GRS-S is a teacher-completed rating scale used in gifted assessment. The GRS-Electronic Form provides an alternative method of administering…

The purpose of this report is to review ETS psychometric contributions that focus on test scores. Two major sections review contributions based on assessing test scores' measurement characteristics and other contributions about using test scores as predictors in correlational and regression relationships. An additional section reviews additional…

This paper illustrates that the psychometric properties of scores and scales that are used with mixed-format educational tests can impact the use and interpretation of the scores that are reported to examinees. Psychometric properties that include reliability and conditional standard errors of measurement are considered in this paper. The focus is…

The Wisconsin Card Sorting Test (WCST) assesses executive and frontal lobe function and can be administered manually or by computer. Despite the widespread application of the 2 versions, the psychometric equivalence of their scores has rarely been evaluated and only a limited set of criteria has been considered. The present experimental study (N =…

Large-scale testing programs involving classification decisions typically have multiple forms available and conduct equating to ensure cut-score comparability across forms. A test developer might be interested in the extent to which an examinee who happens to take a particular form would have a consistent classification decision if he or she had…

Developed an Italian version of the Self-Description Questionnaire (SDQ-III) and studied the reliability and factorial validity of this translated instrument. Results show that the translated version has psychometric properties similar to those of the original English version. (SLD)

The purpose of this paper is to highlight some psychometric cautions that should be observed when seeking to develop short form versions of tests. Several points are made: (1) score reliability is impacted directly by the characteristics of the sample and testing conditions; (2) sampling error has a direct influence on reliability and factor…

Studied descriptive measurement reliability and validity of scores from the newly developed Mathematics Self-Efficacy Scale (MSES) for class and test with a sample of 302 Australian high school students. Results provide some evidence for the psychometric properties of the MSES in both contexts, but there is evidence of failure to counterbalance…

The purpose of this research was to study the effects of violations of standard multiple-choice item writing principles on test characteristics, student scores, and pass-fail outcomes. Four basic science examinations, administered to year-one and year-two medical students, were randomly selected for study. Test items were classified as either…

A study was conducted to compare the psychometric qualities of two forms of an identical survey: one administered in a paper-and-pencil format and the other administered in Web format. The survey addressed the topic of college course anxiety and used to survey a sample of 236 undergraduate students. The psychometric qualities investigated included…

Reliability and validity of 4-point and 6-point scales were assessed using a new model-based approach to fit empirical data from 165 graduate students completing an attitude measure. Results suggest that the issue of four- versus six-point scales may depend on the empirical setting. (SLD)
