Lee Cronbach once expressed the view that all roads lead to construct validity. In looking to clarify the consensus definition of validity, and its place in assessment, Newton is also led to the troublesome idea of construct validity. To be sure, he addresses other validity issues, but in this commentary, I will restrict my attention to construct…

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…

The inevitable responses to high stakes testing, wherein students' test scores are highly consequential for teachers and administrators, include cheating, excessive test preparation, changes in test scoring and other forms of gaming to ensure that test scores appear high. Over the last decade this has been demonstrated convincingly in the USA, but…

Life sciences faculty agree that developing scientific literacy is an integral part of undergraduate education and report that they teach these skills. However, few measures of scientific literacy are available to assess students' proficiency in using scientific literacy skills to solve scenarios in and beyond the undergraduate biology classroom.…

Examines evidence presented for the validity of the American Council on the Teaching of Foreign Languages (ACTFL) rating scales in "Foreign Language Annals" (1990), "System" (1992), and "Proficiency Guidelines" (1982, 1986). The article argues that this evidence is insufficient to support a claim for validity. (36…

This handbook is designed as a quick reference for first-year teachers who find themselves in an assessment driven environment with little experience to help make sense of the language, underlying philosophy, or organizational structure of the assessment system. The handbook begins with advice on developing and evaluating effective learning…

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…

Work Keys (occupational tests developed by American College Testing) could support an employer's human resource function in a number of ways: (1) communicating to educators the skill requirements for an employer's particular jobs on a national basis; (2) providing students with a realistic preview of skills needed for jobs and an assessment of…
