Although previous studies have attempted to use different experiences of raters to rate product creativity by adopting the Consensus Assessment Method (CAT) approach, the validity of replacing CAT with another measurement tool has not been adequately tested. This study aimed to compare raters with different levels of experience (expert ves.…

In high-stakes writing assessments, rater training in the use of a rating scale does not eliminate variability in grade attribution. This realisation has been accompanied by research that explores possible sources of rater variability, such as rater background or rating scale type. However, there has been little consideration thus far of…

Students at the University of Edinburgh do almost all their work on computers, but at the end of the semester they are examined by handwritten essays. Intuitively it would be appealing to allow students the choice of handwriting or typing, but this raises a concern that perhaps this might not be "fair"--that the choice a student makes,…

There is variability in the estimation of an equating transformation because common-item parameters are obtained from responses of samples of examinees. The most commonly used standard error of equating quantifies this source of sampling error, which decreases as the sample size of examinees used to derive the transformation increases. In a…

This paper illustrates a method to study rater severity across exam administrations. A multi-facet Rasch model defined the ratings as being dominated by four facets: examinee ability, rater severity, project difficulty, and task difficulty. Ten years of data from administrations of a histotechnology performance assessment were pooled and analyzed…

Compared three methods of rating thoughts: self-rating by subjects, rating by experts with thoughts presented randomly, and rating by experts with thoughts presented in context among 107 students who listed their thoughts prior to giving a speech. Results indicated all three methods were equal in predictions of speech anxiety and performance.…

This paper examines whether individuals who train themselves to score a performance assessment will rate acceptably when compared to known standards. Research on the efficacy of rater self-training materials developed by the Center for Applied Linguistics for the Texas Oral Proficiency Test (TOPT) is examined. Rater self-materials are described…

This paper discusses recent developments in language testing. It begins with a review of the traditional criteria that are applied to all measurement and outlines recent emphases that derive from the expanding range of stakeholders. Drawing on Alderson's seminal work, criteria are presented for evaluating communicative language tests. Developments…

A preliminary study is reported of the use of new multifaceted Rasch measurement mechanisms for investigating rater characteristics in language testing. Ratings from four judges of scripts from 50 candidates taking the International English Language Testing System test, a test of English for Academic Purposes, are analyzed. The analysis…

A group of seven Japanese-language Oral Proficiency Interview (OPI) testers licensed by the American Council on the Teaching of foreign Languages (ACTFL) conducted research related to ACTFL-OPI criteria. They first examined 24 audiotaped interview tests to see what kind of consistency there would be when individual testers applied general criteria…

In this study, planning time was manipulated as a variable in a trial administration of a semi-direct oral interaction test. Discourse analytic techniques were used to determine the nature and/or significance of difference in the elicited discourse across two conditions in terms of complexity and accuracy. Findings suggest that planning time may…

This study investigated the effects of three aspects of language testing (test task, familiarity with an interviewer, and test method) on both tester and tested. Data were drawn from several previous studies by the researcher. Concerning test task, data were analyzed for the type of topic students wanted most to talk about or preferred not to talk…

This study aimed to comprehensively investigate the impact of a word-processor on an ESL writing assessment, covering comparison of inter-rater reliability, the quality of written products, the writing process across different testing occasions using different writing media, and students' perception of a computer-delivered test. Writing samples of…

Problems inherent in the holistic scoring of essay examinations written by limited-English-speakers are examined, particularly in the context of one California state college in which English writing skills, holistically assessed, are required for graduation. These problems include lack of interrater reliability, raters' perceptions of their role,…

This study investigated whether different groups of native speakers assess second language learners' language skills differently for three elicitation techniques. Subjects were six learners of college-level Arabic as a second language, tape-recorded performing three tasks: participating in a modified oral proficiency interview, narrating a picture…
