Paul E. Newton's article on the consensus definition of validity tackles a number of big issues and makes a number of strong claims. I agreed with much of what he said, and I disagreed with a number of his claims, but I found his article to be consistently interesting and thought provoking (whether I agreed or not). I will focus on three general…

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 "HOPE Scale" was developed to identify academic and social components of giftedness and talent in elementary-aged students with particular attention to students from low-income and/or culturally diverse families. Based on previous findings, additional research was conducted on revisions made to the "HOPE Scale". Items were…

The Mayo-Portland Adaptability Inventory 4 (MPAI-4) is a valid and reliable assessment tool to detect clinical impairments in patients with acquired brain injury. The tool is widely used by rehabilitation therapists worldwide, given its good psychometric properties and its availability in several languages. The purpose of this study was to…

This chapter introduces theory that undergirds the role of testing adaptations in assessment, provides examples of item modifications and testing accommodations, reviews research relevant to each, and introduces a new paradigm that incorporates opportunity to learn (OTL), academic enablers, testing adaptations, and inferences that can be made from…

This study investigates the validity of the Diagnostic College English Speaking Test (DCEST) in the context of EFL teaching and learning in China. The experiment was conducted in three stages over the course of eight weeks at a national key university in China. By means of test administration and questionnaire survey, the researcher gathered…

The vast majority of measures have, at their core, a purpose of personal and social change. If test developers and users want measures to have personal and social consequences and impact, then it is critical to consider the consequences and side effects of measurement in the validation process itself. The consequential basis of test interpretation…

Test score validity takes center stage in the debate over the use of high school exit exams. Scant literature addresses the amount of conditional standard error of measurement (CSEM) present in individual student results on high school exit exams. The purpose of this study is to fill a void in the literature and add a national review of the CSEM,…

In response to Lissitz and Samuelsen (2007), the author reconstructs the historical arguments for the more comprehensive unitary concept of validity and the principles of scientific inquiry underlying it. Her response is organized in terms of four questions: (a) How did validity in educational measurement come to be conceptualized as unitary, and…

This study used confirmatory factor analysis (CFA) to examine the comparability of the National Nurse Aide Assessment Program (NNAAP[TM]) test scores across language and administration condition groups for calibration and validation samples that were randomly drawn from the same population. Fit statistics supported both the calibration and…

The Woodcock Johnson III Brief Assessment is a "maximum performance test" (Reynolds, Livingston, Willson, 2006) that is designed to assess the upper levels of knowledge and skills of the test taker using both power and speed to obtain a large amount of information in a short period of time. The Brief Assessment also provides an adequate…

Lissitz and Samuelsen (2007) propose a new framework for validity theory and terminology, emphasizing a shift in theory and practice toward issues of test content rather than constructs. The author of this article argues that several of Lissitz and Samuelsen's critiques of validity theory focus on previously considered, but subsequently discarded,…

In keeping with the theme of the International Language Testing Association/Language Testing Research Colloquium Conference in 2008, "Focusing on the Core: Justifying the Use of Language Assessments to Stakeholders," I define "stakeholder-friendly tests," "defensible testing," and "testing-context analysis."…

A qualitative study investigated the test-taking behaviors, knowledge, and perceptions of 20 urban, adult basic education students reading at third to fifth grade equivalency levels. The entire reading comprehension subtest of the Test of Adult Basic Education, levels E and M, was administered under standardized conditions. A combination of…

Instructions for the administration of the Opinions about Deaf People Scale are given. This scale measures the beliefs of hearing adults about the capabilities of deaf adults. The somewhat ambiguous title of the instrument is designed to avoid leading respondents to respond in socially desirable ways. The instrument is based on misconceptions…
