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…

This article discusses a particular type of concordance table and the potential for test score misuse that may result from employing such a table. The concordance that is discussed is typically created between scores on different, nonequatable versions of a test that share the same or close to the same test title. These concordance tables often…

Discusses the comparison of groups of individuals who were administered different forms of a test. Focuses on the situation in which there is little overlap in content between the test forms. Reviews equating problems in national tests in Canada and Israel. (SLD)

Research on true-false (TF), multiple-choice, and alternate-choice (AC) tests is reviewed, discussing strengths, weaknesses, and the usefulness in classroom and large-scale testing of each. Recommendations are made for improving use of AC items to overcome some of the problems associated with TF items. (SLD)

Examined the performance of Irish students on multiple-choice, short-answer, and extended-response item sets from the Third International Mathematics and Science Study to determine whether Ireland's relative rank among the more than 40 countries involved remained stable. Findings provide additional evidence that comparing student achievement…

If annual performance assessments are to yield results that can be compared from year to year, many technical problems must be addressed. It is essential that tests to be equated measure the same construct. Methods of equating performance assessment scores, ways of equating system assessments, and standard setting are discussed. (SLD)

Different methodologies for linking tests across languages are reviewed and evaluated, focusing on monolingual item response theory, bilingual group designs, and matched monolingual group designs. These methods, although not without weaknesses, are superior for promoting score comparability than methods that rely on translation or expert judgment…
