Cognitive diagnostic assessment is known for its capacity to provide detailed feedback to test-takers, which can inform instruction and guide learning. Besides this core strength of the assessment approach, the measurement procedure also works as a construct validation method in itself. Previous studies do not call attention to this aspect of…

Modern vocabulary size tests are generally based on the notion that the more frequent a word is in a language, the more likely a learner will know that word. However, this assumption has been seldom questioned in the literature concerning vocabulary size tests. Using the Vocabulary of American-English Size Test (VAST) based on the Corpus of…

One of the most critical steps in the test development process is defining the construct, or the knowledge, skills, or abilities, to be assessed. This foundational step provides the basis for initial assumptions about the meaning of test scores and serves as a reference for subsequent validity research. In this paper, we describe the purpose of…

Reverse engineering (RE) can play an important role in the re-designing tests in L2 English. It can also enrich the aim of teaching the same as raising children through academic achievement. In addition, it can play a key role in helping students understand how much their test is valid by using Standard reverse engineering (SRE). This paper is a…

The Norwegian government recommends a systematic language assessment of all four-year-olds as part of the general health surveillance program for the purpose of identifying children at risk of language delay. This study aimed to investigate the construct validity of the recommended language screening tool called LANGUAGE4 [SPRÅK4] by first…

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…

Despite the current need for reliable and valid test instruments in different countries in order to monitor the sign language acquisition of deaf children, very few tests are commercially available that offer strong evidence for their psychometric properties. This mirrors the current state of affairs for many sign languages, where very little…

Although programs for teaching and testing of English as a second language (ESL) are often evaluated for their attention to communicative competence, there is no consensus on the nature of the communicative competence construct(s) and little empirical support for the various explanatory models. The theoretical literature related to communicative…

This study examined the construct validity of the "e-rater"® automated essay scoring engine as an alternative to human scoring in the context of TOEFL® essay writing. Analyses were based on a sample of students who repeated the TOEFL within a short time period. Two "e-rater" scores were investigated in this study, the first…

The thought of Samuel Messick has influenced language testing in 2 main ways: in proposing a new understanding of how inferences made based on tests must be challenged, and in drawing attention to the consequences of test use. The former has had a powerful impact on language-testing research, most notably in Bachman's work on validity and the…
