Validity in psychometrics refers to the degree to which evidence and theory supports the interpretations drawn from a test, and Messick's Contemporary Validity Theory (1994) includes several facets with well-established evidence collection methods. However, there is a lack of consensus on appropriate methods of evaluating the facet of…

Assessment of functional impairment provides information that is complementary to diagnostic criteria information and is critical for identifying targets for intervention and evaluating treatment outcomes. This review presents summative psychometric information for five multidimensional measures of functional impairment developed for use with…

Background: Digital-first assessments leverage the affordances of technology in all elements of the assessment process--from design and development to score reporting and evaluation to create test taker-centric assessments. Objectives: The goal of this paper is to describe the engineering, machine learning, and psychometric processes and…

The Wechsler Individual Achievement Test (WIAT-4) is the latest iteration of a popular instrument that psychologists employ to assess academic achievement. The WIAT-4 authors make both pragmatic and measurement claims about the instrument. The pragmatic claims involve being useful for identifying individuals in certain academic achievement-related…

Scholars have lamented that current methods of assessing student performance do not align with contemporary views of learning as situated within students, contexts, and time. Here, we introduce and describe one theoretical--psychometric paradigm--termed "dynamic measurement"--designed to provide a valid representation of the way students…

We investigated the ecological validity of performance measures from a computer-based assessment tool that utilises scripted video vignettes. The intended purpose of this tool is to assess the maintenance and repair skills of automotive technician apprentices, complementing traditional hands-on assessment formats from the German journeymen's…

Clinical cognitive ability assessment--and its corollary, score interpretation--are in a state of disarray. Many current instruments are designed to provide a bevy of scores to appeal to a variety of school psychologists. These scores are not all grounded in the attribute's theory or developed from sound measurement or psychometric theory. Thus,…

This research is motivated by the perspective that when empirical studies and assessment frameworks inform each other, assessments can enrich science education and strengthen its connections to modern science. The research proposes a bioenergy competency assessment for science education. It uses an argument-based approach to validation. Multiple…

Charles Spearman and L. L. Thurstone were pioneers in the field of intelligence. They not only developed methods to assess and understand intelligence, but also developed theories about its structure and function. Methodologically, their approaches were not that distinct, but their theories of intelligence were philosophically very different --…

The main purpose of this study was to conduct a validation analysis of student surveys of teaching effectiveness implemented at Bangkok University, Thailand. This study included three phases; survey development, a pilot study, and a full implementation study. Four sources of validity evidence were collected to support intended interpretations and…

Paul E. Newton provides an insightful and scholarly overview of central issues in validity theory. As he notes, many of the conceptual problems in validity theory derive from the fact that the word "validity" has two meanings. First, it indicates "whether a test measures what it purports to measure." This is a factual claim about the psychometric…

This article examined the impact of unscorable item responses on the psychometric validity and practical interpretability of scores on the Restructured Clinical (RC) Scales of the Minnesota Multiphasic Personality Inventory-2/Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2/MMPI-2-RF). In analyses conducted with five…

The purpose of this study was to enhance the meaning of the scores of an English-language test by developing performance levels and descriptors for reporting overall test performance. The levels and descriptors were intended to accompany the total scale scores of TOEFL Junior® Standard, an international test of English as a second/foreign…

The purpose of this report is to review ETS psychometric contributions that focus on test scores. Two major sections review contributions based on assessing test scores' measurement characteristics and other contributions about using test scores as predictors in correlational and regression relationships. An additional section reviews additional…

Accurate interpretations of large-scale assessment results and sound judgments about students' mathematical literacy depend on these assessments' validity and reliability. One important type of evidence towards this validation is the dimensionality analysis, which explores the conformity between the intended factorial structure (related closely to…
