The way in which validity has been conceptualized has changed throughout the years. The focus in validation studies shifted from evaluating distinct components of validity to developing a comprehensive argument for the use and interpretations of test scores. The argument-based approach to validity incorporates the distinct types of the…

The redesigned "TOEIC Bridge"® tests were designed to evaluate test takers' English listening, reading, speaking, and writing skills in the context of everyday adult life. In this paper, we summarize the initial validity argument that supports the use of test scores for the purpose of selection, placement, and evaluation of a test…

Critical language assessment (CLA) has been addressed in numerous studies. However, the majority of the studies have overlooked the need for a practical framework to measure the CLA dimension of teachers' language assessment literacy (LAL). This gap prompted us to develop and validate a critical language assessment literacy (CLAL) scale to further…

This report provides a brief overview of how the "TOEIC"® program has adopted an argument-based approach to validity in order to support the use of the TOEIC tests. This approach emphasizes the need to explicitly state claims about the measurement quality and intended use of a test and to support those claims with evidence. This report…

Some writers invoke the notion of washback validity, holding that a test's validity should be gauged by the degree to which it has…

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…
