The teaching of English as a foreign language in Indonesia has a long history, and it is always important to ask whether the assessment of the students' language skills has been valid and reliable. A screening of many articles in several prominent databases reveal that a number of evaluation studies have been done by Indonesian scholars in the…

A method for medical screening is adapted to differential item functioning (DIF). Its essential elements are explicit declarations of the level of DIF that is acceptable and of the loss function that quantifies the consequences of the two kinds of inappropriate classification of an item. Instead of a single level and a single function, sets of…

This article proposes that sampling design effects have potentially huge unrecognized impacts on the results reported by large-scale district and state assessments in the United States. When design effects are unrecognized and unaccounted for they lead to underestimating the sampling error in item and test statistics. Underestimating the sampling…

In the attempt to identify or prevent unfair tests, both quantitative analyses and logical evaluation are often used. For the most part, fairness evaluation is a pragmatic attempt at determining whether procedural or substantive due process has been accorded to either a group of test takers or an individual. In both the individual and comparative…

Item-discrimination indices are numbers calculated from test data that are used in assessing the effectiveness of individual test questions. This article asserts that the indices are so unreliable as to suggest that countless good questions may have been discarded over the years. It considers how the indices, and hence overall test reliability,…

Presently available test statistics for the Rasch model are shown to be insensitive to violations of the assumption of test unidimensionality. Two new statistics are presented. One is similar to available statistics, but with some improvements; the other addresses the problem of insensitivity to unidimensionality. (Author/JKS)

Four hypotheses regarding stability of response process and response in personality testing are tested and supported. (RC)

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)

This report summarizes the findings of Jackson and Lahadern who used a revised form of the Student Opinion Poll (SOP) and a questionnaire to study the intercorrelations of attitudes and achievement. The study found that: (1) first graders have attitudes toward school work but these attitudes were not differentiated toward specific school subjects;…

The Selected Marker Tests were examined for scoring problems and internal consistency and were administered orally to sixth and seventh graders. Scoring problems were discovered and changes were suggested. The problem was found to be item reliability rather than interrater reliability. (Author/MH)

The DELPHI procedure requires respondents to reply to several questionnaire iterations with subsequent rounds containing previous round feedback. This study investigated the methodology (response rates, effects of feedback) and offered evidence that large-scale DELPHI surveys are not as advantageous as has previously been indicated. Suggestions…

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)

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)

A series of studies on conceptual and design problems in competency-based measurements are explained. The concept of validity within the context of criterion-referenced measurement is reviewed. The authors believe validation should be viewed as a process rather than an end product. It is the process of marshalling evidence to support…
