We review common situations in Bayesian latent variable models where the prior distribution that a researcher specifies differs from the prior distribution used during estimation. These situations can arise from the positive definite requirement on correlation matrices, from sign indeterminacy of factor loadings, and from order constraints on…

This article presents the consensus of an National Council on Measurement in Education Presidential Task Force on Foundational Competencies in Educational Measurement. Foundational competencies are those that support future development of additional professional and disciplinary competencies. The authors develop a framework for foundational…

Evidence-based assessment (EBA) requires that investigators employ scientific theories and research findings to guide decisions about what domains to measure, how and when to measure them, and how to make decisions and interpret results. To implement EBA, investigators need high-quality assessment tools along with evidence-based processes. We…

In December 2022, federal, state and territory education ministers released a National Teacher Workforce Action Plan to improve teacher supply and retention in the profession. While recognising the important role that Highly Accomplished and Lead Teacher (HALT) certification could play, the plan also recognised that the current approach to…

Resistant behaviors in multicultural courses are a common dilemma within counselor education. On the basis of psychological reactance theory (J. W. Brehm, 1966), the authors created a multicultural training reactance scale to measure the construct. Exploratory factor analysis and initial reliability and validity data are presented, followed by…

Dynamic Measurement Modeling (DMM) is a psychometric paradigm that uses longitudinal data to estimate students' capacity to learn over the course of an educational program (i.e., growth scores). Here, we provide justification for this approach in health professions education and demonstrate its proof of concept with three time-points of USMLE Step…

In this article I provide an overview of the methodological issues involved in measuring constructs relevant to character development and education. I begin with a nontechnical overview of the 3 fundamental psychometric properties of measurement: reliability, validity, and equivalence. Developing and evaluating measures to ensure evidence of all 3…

Examinees' thinking processes have become an increasingly important concern in testing. The responses processes aspect is a major component of validity, and contemporary tests increasingly involve specifications about the cognitive complexity of examinees' response processes. Yet, empirical research findings on examinees' cognitive processes are…

The distinction between facts and moral values is highly desirable: science and politics should keep to their own territories. Traditionally speaking, science can be seen as an ivory tower, which attempts to do its job in isolation of external influences. Politics does not mandate methods of scientific research or standards of justification;…

It is imperative that counselors understand how to critically evaluate assessments before using them to make clinical decisions. This evaluation can be conducted through integrating the 5 sources of validity. Each source of validity is discussed, along with methods to appraise psychometric quality, throughout this special issue.

The purpose of this statement is to inform those using or considering the use of value-added models (VAM) about their scientific and technical limitations in the evaluation of educators and programs that prepare teachers. The statement briefly reviews the background and current context of using VAM for evaluations, enumerates specific psychometric…

Current educational policies rely on educational assessments. However, the technical aspects of assessments are often unknown to policy makers, which is dangerous because sound assessment policy requires knowledge of the strengths and limitations of educational tests. In this article, we discuss the importance of informing policy makers of…

Composition assessment scholars have exhibited uneasiness with the language of norming grounded in distaste for the psychometric assumption that achievement of consensus in a communal assessment setting is desirable even at the cost of individual pedagogical values. Responding to the problems of a "reliability" defined by homogenous agreement,…

Recently, student outcomes have bubbled to the top of debates about how to evaluate teaching in community and liberal arts colleges, universities, and professional schools, but even more international attention has been riveted on how outcomes are being used to evaluate teachers and administrators K-12 (Harris, 2012; Rowen & Raudenbush, 2016;…

Everyone who runs a youth program believes in their hearts that their program helps kids, but in their heads, they know they need convincing data to prove it. This guide--updated from 2011--is here to help them get the data they need. The guide addresses a common problem throughout the youth field: Out-of-school time (OST) programs can help youth…
