The argument-based approach to validation involves two steps; specification of the proposed interpretations and uses of the test scores as an interpretive argument, and the evaluation of the plausibility of the proposed interpretive argument. More ambitious interpretations and uses tend to involve an extended network of inferences and assumptions and require extensive evidence for their support. Simpler interpretations do not claim much, and therefore, may not require much evidential support. The evaluation of score based decisions generally requires an evaluation of the consequences of the decision rule. In any case, the claims that are being made need to be justified.

Kane’s argument-based framework is summarized and examined. He implicitly appeals to the backgrounded concepts of fairness and justice. From there it is a short distance to grounding the whole system in the mundane notion of truth. In fact, valid argument systems must depend on representations that are ‘true’ by virtue of agreement with purported facts. As a friendly amendment, therefore, I argue that (provided the ceteris paribus, all else being equal, requirement is met) agreement with known facts in testing, experimental research, and scientific measurement counts for a great deal more than disagreement. It follows by Peircean ‘exact logic’ that higher test scores (if the tests have any validity at all) are invariably more informative (interpretable in general) and thus more useful than lower scores. Why? Because higher scores show more agreement between the test-makers and the higher scoring test-takers about whatever facts (or performances) may be at issue. Exceptions are cases where the ceteris paribus requirement is not met. Necessary (but testable) inferences follow for interpretations and uses of ‘cutscores.’

The fuzziness of assessing second language speaking performance raises two difficulties in scoring speaking performance: indistinction between adjacent levels and overlap between scales. To address these two problems, this article proposes a new approach, confidence scoring, to deal with such fuzziness, leading to confidence scores between two adjacent levels applied to three scales. Since confidence scores have to be transformed to an exact score for test interpretation and use, membership functions and rule bases are applied and a confidence scoring algorithm is developed. Confidence scoring is demonstrated in the paper by an example to facilitate easy understanding. The paper then describes a pilot study that was conducted to try out the confidence scoring design. Initial results reveal that: first, confidence scoring is as feasible as traditional scoring; second, confidence scoring performs better in scoring dependability and in correlations with established benchmarks. At the end of the article, further studies are called for in order to build a validity argument and make further revisions to the confidence scoring method described here.

This study investigated the relationships among the quality of L2 test takers’ notes evaluated in terms of different levels of information and test takers’ performance on open-ended listening tasks tapping into different comprehension subskills. In addition, this study examined the invariance of the structural relationships among the variables across two different note-taking formats, that is, a blank format and an outline format, by employing a multi-group structural equation modeling (SEM) approach. The results indicated that note quality measures, in particular the number of topical ideas found in the notes and the organization of these notes, may be good indicators of test takers’ second language academic listening proficiency. It was also found that despite the invariance of structural relationships among variables across the two note-taking formats, the associations between the open-ended listening measures and note quality measures were slightly stronger in the outline format than in the blank format. The implications of these results for L2 academic listening assessment are considered.

Scores assigned by trained raters and by an automated scoring system (SpeechRaterTM) on the speaking section of the TOEFL iBT™ were validated against a communicative competence criterion. Specifically, a sample of 555 undergraduate students listened to speech samples from 184 examinees who took the Test of English as a Foreign Language Internet-based test (TOEFL iBT). Oral communicative effectiveness was evaluated both by rating scales and by the ability of the undergraduate raters to answer multiple-choice questions that could be answered only if the spoken response was understood. Correlations of these communicative competence indicators from the undergraduate raters with speech scores were substantially higher for the scores provided by the professional TOEFL iBT raters than for the scores provided by SpeechRater. Results suggested that both expert raters and SpeechRater are evaluating aspects of communicative competence, but that SpeechRater fails to measure aspects of the construct that human raters can evaluate.

The important yet under-researched role of item writers in the selection and adaptation of texts for high-stakes reading tests is investigated through a case study involving a group of trained item writers working on the International English Language Testing System (IELTS). In the first phase of the study, participants were invited to reflect in writing, and then audio-recorded in a semantic-differential-based joint discussion, on the processes they employed to generate test material. The group were next observed at a simulated item writers’ editing meeting to refine their texts and items for an IELTS reading test module. The participants’ written descriptions and recorded discussions provided rich data on how source texts were perceived, selected and adapted for the Test. The study reports findings from textual analyses using indices of readability and lexical density from the original material sourced by the item writers and their adapted versions for the test. Results from qualitative and quantitive analyses are discussed in terms of the implications for the IELTS reading module of editing actions such as: reducing redundancy and technical language, changing styles, deciding on potentially sensitive issues and relationships between texts and test items. The important issue of text authenticity in tests such as IELTS is also broached.

This study examined the factor structure of the listening and reading sections of the revised Test of English for International Communication (TOEIC®) test. The data from the TOEIC IP (institutional program) test taken by 569 English learners were randomly split into two samples (n = 285 vs. 284). Four models (higher-order, correlated, uncorrelated, and unitary) were hypothesized on the basis of the literature and were tested with each sample. The results from confirmatory factor analysis suggested that the correlated model fit the data best in both samples. Further, multiple-sample analysis using the two samples supported an invariance of factor loadings, measurement error variances, factor variances, and factor covariances for the correlated model in the revised TOEIC test. The presence of distinctive factors of listening and reading skills supports the reporting of separate scores for each skill, whereas the relatively high correlation between the two factors may support single score reporting. This is in accordance with the formats used to report revised TOEIC test scores. The results of the current study provide empirical support for the reporting practice of the revised TOEIC test and thus for test interpretation based on the test scores.
